Description

Technical Field

[0001] This disclosure relates to the field of computer software technology, and in particular to a multimedia material editing and processing method, apparatus, electronic device, and storage medium. Background Technology

[0002] In today's multimedia era, editing multimedia materials has become increasingly important and common. During the editing process, there are often situations where it's necessary to temporarily interrupt the editing. The draft function allows you to temporarily save the editing state of multimedia materials, so you can resume editing later.

[0003] However, with the continuous development and diversification of multimedia material editing, the draft function has also exposed some problems. For example, as editing methods become increasingly diverse, draft data becomes more and more abundant. Each time a draft is temporarily saved, a large amount of editing status attribute information needs to be persistently stored locally. This not only slows down the speed of saving drafts, but also makes the process of restoring drafts and continuing editing more complex and time-consuming when there is too much draft data, seriously affecting the smoothness and efficiency of multimedia material editing. Summary of the Invention

[0004] This disclosure provides a multimedia material editing and processing method, apparatus, electronic device, and storage medium to solve the problems of slow draft saving speed and the process of restoring drafts for continued editing when there is too much draft data, which becomes more complicated and time-consuming.

[0005] In a first aspect, embodiments of this disclosure provide a multimedia material editing and processing method, the method comprising:

[0006] Determine the first editing task information associated with the first editing state. The first editing state is the initial editing state when the target editing task is just triggered. The editing task information is used to describe the editing results generated by the target editing task in the current editing state due to the triggered editing operations. The target editing task is a multimedia material editing task.

[0007] Determine the second editing task information associated with the second editing state, where the second editing state is the editing state after triggering an editing operation on a target editing task that is already in the first editing state;

[0008] When a draft is stored for a target editing task in the second editing state, the draft of the target editing task in the second editing state is stored. The draft of the target editing task in the second editing state is determined based on the difference between the editing task information of the second editing task and the first editing task.

[0009] Secondly, this disclosure also provides a multimedia material editing and processing apparatus, the apparatus comprising:

[0010] The first determining module is used to determine the first editing task information associated with the first editing state. The first editing state is the initial editing state when the target editing task is just triggered. The editing task information is used to describe the editing results generated by the target editing task in the current editing state due to the triggered editing operations. The target editing task is a multimedia material editing task.

[0011] The second determining module is used to determine the second editing task information associated with the second editing state, wherein the second editing state is the editing state after the target editing task that is already in the first editing state continues to trigger an editing operation;

[0012] The storage processing module is used to store a draft of the second editing state of the target editing task when the draft storage is triggered for the target editing task in the second editing state. The draft of the target editing task in the second editing state is determined based on the difference between the editing task information of the second editing task and the first editing task.

[0013] Thirdly, this disclosure also provides an electronic device, the electronic device comprising:

[0014] At least one processor; and

[0015] A memory communicatively connected to the at least one processor; wherein,

[0016] The memory stores a computer program that can be executed by the at least one processor, which enables the at least one processor to perform the multimedia material editing method described in any of the above embodiments.

[0017] Fourthly, this disclosure also provides a computer-readable medium storing computer instructions that, when executed by a processor, implement the multimedia material editing and processing method described in any of the above embodiments.

[0018] The technical solution of this disclosure can accurately capture the editing status of the target editing task at different stages by determining the first editing task information associated with the first editing state and the second editing task information associated with the second editing state. For multimedia material editing tasks, this means that the specific details of each editing task from the initial editing state to the subsequent further editing state can be recorded in detail. When a draft is stored for a target editing task in the second editing state, the draft content is determined based on the difference between the second and first editing task information. It eliminates the need to repeatedly store the editing task information already in the first editing state for draft content description; only the changes from the first to the second editing state need to be recorded, significantly reducing the amount of data stored. This differential storage method also speeds up storage. Because draft storage is based on differences, the number of read / write operations during draft storage is greatly reduced, avoiding the impact on draft storage speed caused by large amounts of storage required for each draft. This is especially beneficial when frequent editing operations require frequent draft storage, preventing the smoothness of creation from being affected by excessively long storage processes. Since the draft is determined based on the difference in editing task information, the target editing task can be quickly restored to a specific editing state when a draft needs to be recovered, as only the difference information needs to be processed, rather than the entire data of the editing task, reducing potential errors and confusion during data recovery.

[0033] Figure 1This is a flowchart illustrating a multimedia material editing method provided in an embodiment of the present disclosure. This embodiment is applicable to situations where a draft is saved during the editing of multimedia materials. The multimedia material editing method can be executed by a multimedia material editing device, which can be implemented in the form of software and / or hardware, and is generally integrated into any electronic device with network communication capabilities, such as a mobile terminal, a PC, or a server.

[0034] like Figure 1 As shown, the multimedia material editing and processing method of this disclosure embodiment may include the following process:

[0035] S110. Determine the first editing task information associated with the first editing state. The first editing state is the initial editing state when the target editing task is just triggered. The editing task information is used to describe the editing results generated by the target editing task in the current editing state due to the triggered editing operations. The target editing task is a multimedia material editing task.

[0036] See Figure 2 In the process of editing multimedia materials, a draft function is provided. This draft function allows you to temporarily save the editing state of the multimedia material so that you can continue editing operations the next time you enter the editing state. Drafts can be used to edit multimedia materials, pause editing, temporarily save the editing state of the multimedia material as a draft, and restore the draft to continue editing the multimedia material. Saving a draft can generally be understood as persistently storing the editing task information data of each editing state in memory to disk.

[0037] The editing state refers to the state reached by the editing page corresponding to the target editing task after a series of editing operations are performed during the execution of the target editing task. Optionally, the target editing task is a multimedia material editing task, covering editing operations on various types of multimedia materials such as images, audio, and video. Accordingly, the editing state can be characterized by the editing results produced after editing operations on multimedia materials, based on the specific combination of multimedia materials, special effects, and duration of the editing operations on the target editing task. For example, taking video material as an example, in video material editing, the editing state may be the state of the editing page corresponding to the multimedia material editing task after specific filters, subtitles, and music have been added, and the video material has been edited and spliced ​​to a certain extent.

[0038] Optionally, a multimedia material editing task can be an editing task that processes and modifies multimedia materials to achieve a desired editing effect. For example, multimedia materials can refer to various original materials used to constitute a multimedia work, and multimedia materials can include at least one of the following: video materials, audio materials, and image materials. For example, an editing task involves operations such as editing, adding special effects, and creating subtitles for multimedia content such as video, audio, and images.

[0039] The first editing state can refer to the initial editing state when the target editing task is just triggered and jumps to the editing page corresponding to the target editing task. In this case, the first editing state can be understood as the initial editing state when first entering the editing page corresponding to the target editing task or when resuming entering the editing page corresponding to the target editing task.

[0040] The first editing task information describes the editing results of a target editing task in its first editing state, resulting from the editing operations already triggered for that task. For example, in video editing, this might include initial video duration, resolution, and records of any simple trimming operations performed. The first editing task information can independently present the editing effects resulting from triggered editing operations within its respective editing state. This means that when displaying the editing results of a target editing task in its first editing state, the first editing task information can be used to fully present the corresponding editing results.

[0041] Optionally, for the target editing task, the editing operations involved in the editing task information can refer to various editing actions performed during the editing of multimedia materials involved in the target editing task, such as cropping, adding filters, adjusting volume, etc. The editing result can be the actual editing effect produced by the editing operations on the target editing task, such as the cropped video footage, the image colors after applying filters, etc.

[0042] The target editing task is a multimedia material editing task, explicitly defined as any editing task related to multimedia materials, such as image editing, video editing, and audio processing. Optionally, when a target editing task is triggered, the system accurately identifies the target editing task entering its first editing state. For example, in image editing software, the instant the image is imported and the user is redirected to the editing page, signifying entry into the first editing state. While the target editing task is in its first editing state, the system records the editing results generated by the editing operations triggered for the target editing task and stores these results in a preset format as first editing task information. For instance, in video editing, some simple playback preview operations might be performed in the first editing state; the timing of these operations, playback progress, and other information can be included as part of the first editing task information.

[0043] Using the above method, the first editing task information can accurately describe the editing results of the target editing task in the first editing state, and clearly show the progress of the target editing task at the current moment. Furthermore, as the editing task progresses, the first editing task information can be used as the basis for subsequent editing, facilitating comparison between subsequent editing states and the first editing state.

[0044] As an optional but not limited implementation, determining the first editing task information associated with the first editing state includes the following steps A1-A2:

[0045] Step A1: When triggering the creation of a target editing task to perform editing operations, the target editing template selected for the target editing task will be loaded to generate a target editing task in the first editing state.

[0046] Step A2: Record the information of the first editing task associated with the target editing task that is in the first editing state.

[0047] The first editing state can be the initial editing state generated after loading the target editing template corresponding to the target editing task when the target editing task is created and the editing operation is executed. The target editing template can be a pre-set template with a specific structure and style used to load and generate the editing task for the editing operation. It can be used to quickly start the editing task and provide an initial framework for editing. The first editing task information can be used to describe the editing result information of the target editing task in the first editing state after loading the target editing template selected for the target editing task, such as the initial page layout and preset format of the editing page corresponding to the target editing task formed after loading the target editing template.

[0048] Optionally, triggering the creation of a target editing task and executing editing operations can be understood as triggering the creation of a target editing task through a preset triggering method (such as clicking the edit button, selecting multimedia materials for import, etc.) when deciding to start a multimedia material editing task. Optionally, in response to selecting a target editing template for the target editing task from multiple available editing templates, the template data associated with the target editing template selected for the target editing task is read and loaded to generate the editing page corresponding to the target editing task in the first editing state. The target editing template may contain preset elements such as specific layouts, color schemes, and font styles. For example, in video editing, selecting a cinematic template may load specific aspect ratios, subtitle styles, and transition effects.

[0049] After loading the target editing template and generating the first editing state, the system begins recording the first editing task information for the target editing task in the first editing state. This first editing task information may include the specific characteristics of the editing template, the initial settings after loading, and the editing results involved in any minor adjustments made in the initial state. For example, if color parameters are adjusted immediately after loading the editing template, this color parameter adjustment will also be recorded as part of the first editing task information.

[0050] By using the above method, the target editing template can be provided to quickly enter the editing state without having to build the editing task from a completely blank editing state, which greatly saves time and effort, improves the editing efficiency of the target editing task, and records the task information of the first editing state to provide a reference for subsequent editing and modification, and facilitates comparison of the differences in editing task information of different editing states.

[0051] As an alternative but not limited implementation, determining the first editing task information associated with the first editing state includes the following steps B1-B2:

[0052] Step B1: When triggering the editing operation of the editing task corresponding to the draft to restore from the draft, the reference draft selected for the target editing task will be loaded to generate the target editing task in the first editing state. The reference draft is the draft selected from the stored draft information that can enable the target editing task to enter the first editing state.

[0053] Step B2: Record the first editing task information associated with the target editing task that is in the first editing state.

[0054] The first editing state can be the initial editing state when restoring from a draft to the target editing task after loading the reference draft selected by the target editing task. The first editing task information describes the results of editing operations in the target editing task while in the first editing state, covering various initial characteristics after restoring the target editing task to the first editing state from a draft. The reference draft is a draft selected from stored draft information that enables the target editing task to enter the first editing state; for example, it can be a draft in any editing state saved in the draft box, and serves as the basis for restoring the editing task.

[0055] Triggering the restoration from draft to the corresponding editing task to perform editing operations can mean that when it is decided to restore the editing task from the saved draft, the restoration operation from the draft to the editing page corresponding to the editing task is initiated through a preset trigger method (such as clicking the restore draft button, selecting a reference draft item from the draft box, etc.), which means that it is desired to continue the previously unfinished editing task.

[0056] Specifically, after selecting a specific reference draft from the stored draft information, the corresponding draft data for that reference draft is loaded, restoring the editing state from the reference draft to the editing state of the target editing task associated with that reference draft—that is, the first editing state of the target editing task. For example, in video editing, if multiple drafts were previously saved, and one draft is now selected for restoration, information such as the video clips, applied effects, and editing positions within that draft will be loaded, returning the video editing task to the editing state of the editing task associated with the previously saved draft.

[0057] When the target editing task is restored to its first editing state, the first editing task information corresponding to the target editing task in its current first editing state is recorded, just as it was when the editing task was initially created. This first editing task information includes content loaded from the reference draft and any minor adjustments that may be made immediately after restoration. For example, if the video playback speed is adjusted immediately after restoring the draft, this playback speed adjustment will be recorded as part of the first editing task information.

[0058] Using this method, when pausing and resuming editing multimedia materials, you can quickly return to the previous editing state by restoring from a draft, without having to start over, saving time and effort. Since you can choose from multiple saved drafts to restore, you effectively have multiple possible starting points for editing. This allows you to try different editing paths, compare different versions of the edited results, and make better decisions. This method encourages iterative editing, continuously improving and refining multimedia materials. You can save drafts at different points in time, and then choose the appropriate draft to restore and further edit as needed, gradually optimizing the edited results.

[0059] As an optional but not limited implementation, recording the first editing task information associated with the target editing task in the first editing state includes the following steps:

[0060] Perform a deep copy of the first editing task information related to the target editing task in the first editing state and back it up in the running memory.

[0061] The target editing task enters its first editing state during the initial creation of the editing task or after a draft restoration operation. In the first editing state, the specific attributes and characteristics of the target editing task can be described using the first editing task information. For example, in an image editing task, the first editing state might be when an image has just been opened. The first editing task information corresponding to this first editing state could include the image's original size, color mode, and any basic adjustments already applied.

[0062] To better record the information of the first editing task, a deep copy can be used. A deep copy means not only copying the surface information of the first editing task, but also recursively copying all objects and sub-objects contained within it, ensuring a completely independent copy. This is done to guarantee the integrity and independence of the backed-up first editing task information; even if the original first editing task information changes during subsequent editing, the backup copy will not be affected. For example, since the ArkTs development language runs on a JS engine and all types of objects are JSObjects, this mechanism can be used to perform a deep copy of the first editing task information related to the target editing task in its first editing state.

[0063] The first editing task information obtained from the deep copy is stored in RAM, which features fast read and write capabilities, allowing for rapid access to the backup data when needed. This backup method is suitable for scenarios requiring quick restoration to the first editing state, such as in case of accidental operation or software malfunction during editing. It allows for rapid restoration from the backup in RAM, avoiding data loss and the hassle of restarting the editing process.

[0064] By employing the above method, and backing up the first editing task information in RAM through a deep copy, data security is significantly improved. Because the backup copy is completely independent of the original data, it will not be affected by damage to the original data. The deep copy ensures complete independence between the backup and original data. Modifying the original data will not affect the backup data, and vice versa. This guarantees that when data needs to be restored, a state completely consistent with the state at the time of backup can be obtained. Furthermore, since the backup record is stored in RAM, restoration to the first editing state can be very fast. The fast read / write characteristics of RAM allow the system to load the backed-up first editing task information into the target editing task in a short time. At the same time, because the backup is performed in RAM, it does not consume a large amount of disk space, making it suitable for various devices and environments.

[0065] Optionally, the editing task information describes various status and configuration data of the reference functional modules involved in the editing operation to form the editing result of the target editing task; for example, "hasMusic=true" explicitly indicates whether the music reference function is used. Optionally, the editing task information also describes the file paths corresponding to the multimedia materials in the editing task; for example, multimedia materials may include images, videos, audio files, etc., and generally only the file paths corresponding to the multimedia materials are recorded in memory.

[0066] Alternatively, editing task information can be represented as string and numeric types, which are relatively simple, occupy less storage space, and are easy to process and store.

[0067] Optionally, since multimedia materials are typically large, storing them directly in memory would consume significant resources. Therefore, it's generally best to only record the file paths of the multimedia materials in memory. This allows the multimedia materials to be loaded based on the file paths when needed, avoiding unnecessary memory usage. Multimedia materials are usually stored in specific directories on disk or via cloud storage. Applications can use file system APIs or dedicated multimedia libraries to manage and access multimedia materials.

[0068] S120. Determine the second editing task information associated with the second editing state. The second editing state is the editing state after the target editing task, which is already in the first editing state, continues to trigger editing operations.

[0069] Once it has been determined that the target editing task is in the first editing state and the information associated with the first editing task in the first editing state has been recorded, a series of editing operations can be performed on the target editing task in the first editing state. As more editing operations are triggered on the target editing task already in the first editing state, it begins to transition to the second editing state. For example, in image editing, the target editing task in the first editing state might have loaded an image and performed simple cropping. When further operations such as adding filters and adjusting colors are performed, the target editing task is triggered to transition to the second editing state.

[0070] Optionally, as new editing operations continue to be performed on the target editing task in the first editing state, changes in the corresponding editing results of the target editing task are monitored and recorded in real time. These changes include, but are not limited to, changes in the editing results resulting from operations such as pixel modification of images, clipping of video, and volume adjustment of audio. Once a new editing operation is completed, the second editing task information associated with the target editing task in the second editing state is determined. The second editing task information will describe in detail the results of the target editing task in the second editing state, including all changes from the first editing state to the second editing state. For example, in document editing, the first editing state might be the input of some text content, while the second editing state might be operations such as formatting these texts or adding images; the second editing task information will record these specific changes.

[0071] By employing the above process and determining the second editing state and associated second editing task information, every step and change made by the user during the editing process can be completely recorded. This is particularly important for complex multimedia material editing tasks, allowing for easy review and tracing of the editing history, facilitating modifications and adjustments. During multimedia material editing, needs and creative ideas may constantly change. Determining the second editing state and associated task information allows the system to flexibly adapt to these changes, recording new editing operations and results at any time, providing greater creative freedom and flexibility for multimedia material editing.

[0072] As an optional but not limited implementation, determining the second editing task information associated with the second editing state includes the following steps C1-C2:

[0073] Step C1: In response to the editing operation triggered on the target editing task in the first editing state, continue to perform editing processing on the target editing task in the first editing state so that the target editing task changes from the first editing state to the second editing state.

[0074] Step C2: Record the information of the second editing task associated with the target editing task that is in the second editing state.

[0075] When an editing operation is performed on a target editing task in its first editing state, the operation is detected and a response is taken. For example, in image editing, cropping or color adjustments might be performed on an image in its first editing state. Based on the editing operation triggered on the target editing task, further editing processing is performed on the target editing task, causing its state to gradually transition from the first editing state to the second editing state. For example, in video editing, the first editing state is the original video clip; after editing operations such as trimming and adding effects, it enters the second editing state.

[0076] When the target editing task enters the second editing state, it records the second editing task information at that time. This second editing task information includes the specific characteristics of the target editing task in the second editing state. For example, in document editing, the second editing task information may include newly added text content, modified formatting, etc.

[0077] Using the above method, editing operations can continue from the first editing state, achieving a smooth transition from the first to the second editing state. By recording the second editing task information, every step and change in the editing process can be accurately recorded, allowing for an understanding of the evolution from the first to the second editing state. Thus, when it's necessary to save the current editing state or restore to a previous state, one can switch between different editing states at any time according to their creative ideas and needs, enabling flexible editing operations.

[0078] As an optional but not limited implementation, recording the second editing task information associated with the target editing task in the second editing state includes the following steps:

[0079] Perform a deep copy of the second editing task information related to the target editing task in the second editing state and back it up in the running memory.

[0080] The above process is the same as the process of performing a deep copy of the first editing task information related to the target editing task in the first editing state and backing it up in the running memory, so it will not be described again here.

[0081] S130. When the draft storage is triggered for the target editing task in the second editing state, the draft storage of the second editing state of the target editing task is performed. The draft storage of the second editing state of the target editing task is determined based on the difference between the editing task information of the second editing task and the first editing task.

[0082] The second editing state refers to the editing state of the target editing task after one or more editing operations, which is more varied and developed compared to the first editing state. Triggering draft storage for the target editing task in the second editing state refers to the process of restoring and storing the draft of the editing results formed by the triggered editing operations while the target editing task is in the second editing state. The editing task information difference refers to the difference between the editing task information in the second editing task and the first editing task, that is, the changes in editing task information that occur from the first editing state to the second editing state.

[0083] See Figure 2 When the decision is made to save the target editing task in the second editing state, a draft save operation is triggered. This is achieved through a preset draft save button, shortcut key, or automatic save mechanism. For example, in image editing software, the user might click the "Save Draft" button to trigger the draft save operation. Draft saving of the target editing task in the second editing state is implemented based on the difference between the second and first editing task information. In other words, the first and second editing task information are first obtained, and then the difference between them is compared. This difference is used to describe the changes that occurred from the first to the second editing state, and this is used to save the draft of the target editing task in the second editing state.

[0084] When a draft is saved for a target editing task in the second editing state, the draft content is determined by the difference between the editing task information in the second editing state and the first editing task information. This method greatly improves storage efficiency. It avoids repeatedly storing information already saved in the first editing state; only the changes from the first to the second editing state need to be recorded, significantly reducing the amount of data stored. For example, if a basic video segment has already been saved in the first editing state, when saving the draft in the second editing state, only newly added effects, adjusted parameters, and other changes need to be recorded, instead of saving the entire video again. This differential storage method also speeds up storage, especially for editing large multimedia materials. It reduces storage time, particularly when frequent editing operations require saving drafts frequently. Because draft storage is based on differential storage, it significantly reduces the number of read / write operations during draft storage, preventing the large amount of data required for each draft storage from affecting the draft storage speed and ensuring that a long storage process does not disrupt the flow of creation.

[0085] Since the draft is determined based on the difference in editing task information, when the draft needs to be restored, the target editing task can be quickly restored to a specific editing state. To return to the second editing state, simply read the first editing task information and apply the difference in the second editing task information to accurately restore the previous editing result. This is extremely helpful for users who may need to backtrack and modify multiple times during the editing process, saving time and effort and improving editing efficiency. At the same time, this method also reduces the risk of recovery errors. Because only the difference in information needs to be processed, rather than all the data from the entire editing task, potential errors and confusion during data recovery are reduced.

[0086] The technical solution of this disclosure can accurately capture the editing status of the target editing task at different stages by determining the first editing task information associated with the first editing state and the second editing task information associated with the second editing state. For multimedia material editing tasks, this means that the specific details of each editing task from the initial editing state to the subsequent further editing state can be recorded in detail. When a draft is stored for a target editing task in the second editing state, the draft content is determined based on the difference between the second and first editing task information. It eliminates the need to repeatedly store the editing task information already in the first editing state for draft content description; only the changes from the first to the second editing state need to be recorded, significantly reducing the amount of data stored. This differential storage method also speeds up storage. Because draft storage is based on differences, the number of read / write operations during draft storage is greatly reduced, avoiding the impact on draft storage speed caused by large amounts of storage required for each draft. This is especially beneficial when frequent editing operations require frequent draft storage, preventing the smoothness of creation from being affected by excessively long storage processes. Since the draft is determined based on the difference in editing task information, the target editing task can be quickly restored to a specific editing state when a draft needs to be recovered, as only the difference information needs to be processed, rather than the entire data of the editing task, reducing potential errors and confusion during data recovery.

[0087] Figure 3 This is a flowchart illustrating another multimedia material editing method provided by an embodiment of the present disclosure. The technical solution of this embodiment further optimizes the process of storing a draft of the second editing state of the target editing task in the foregoing embodiments based on the technical solutions of the above embodiments. This embodiment can be combined with various optional solutions in one or more of the above embodiments.

[0088] like Figure 3 As shown, the multimedia material editing and processing method of this disclosure embodiment may include the following process:

[0089] S310. When triggering the restoration from draft to the corresponding editing task to perform editing operations, the reference draft selected for the target editing task will be loaded to generate the target editing task in the first editing state. The reference draft is a draft selected from the stored draft information that can enable the target editing task to enter the first editing state.

[0090] S320: Record the first editing task information associated with the target editing task that is in the first editing state.

[0091] The first editing state is the initial editing state when the target editing task is first triggered. The editing task information is used to describe the editing results of the target editing task in the current editing state due to the triggered editing operations. The target editing task is a multimedia material editing task.

[0092] S330. Determine the second editing task information associated with the second editing state. The second editing state is the editing state after the target editing task, which is already in the first editing state, continues to trigger editing operations.

[0093] S340. When the draft is stored for the target editing task in the second editing state, if the draft associated with the target editing task has been stored in the local storage device, the information of the second editing task is compared with the information of the first editing task to determine the information change result of the second editing task information relative to the first editing task information.

[0094] See Figure 4 When operating on a target editing task in its second editing state, triggering the draft save function indicates a desire to temporarily save the editing progress for later continuation, or a proactive save due to concerns about data loss in case of unforeseen circumstances. The system first checks whether the draft associated with the target editing task has already been saved on the local storage device, especially whether the draft was saved during the first editing state.

[0095] See Figure 4 The process compares the information of the second editing task, currently in the second editing state, with the previously stored information of the first editing task. The purpose of this comparison is to determine what changes have occurred from the first editing state to the second editing state. This includes, but is not limited to, added, deleted, or modified content. For example, in video editing, the comparison might include changes such as video clip editing, the addition of special effects, and audio adjustments.

[0096] See Figure 4By comparing the information from the second editing task with that from the first editing task, the changes made to the second editing task relative to the first editing task can be determined. By comparing the differences between the two editing task information, it's possible to identify which parameters might have changed during the transition from the first editing state to the second editing state, and the specific details of those changes. This change result can be a concrete list of operations or an abstract description, depending on the implementation. For example, the information change result might be a concrete description such as "a new video clip has been added" or "the brightness and contrast of the video have been adjusted," or a more abstract representation such as "the content has undergone significant modifications."

[0097] By storing only the changes from the first editing state to the second editing state, instead of repeatedly storing the entire editing task's data, storage space can be significantly saved. This is especially true for large multimedia editing tasks, where this method can dramatically improve storage efficiency. When it's necessary to restore a draft, the second editing state can be quickly restored simply by using the changes and the previously stored information from the first editing task.

[0098] As an optional but not limited implementation, the second editing task information is compared with the first editing task information to determine the information change result of the second editing task information relative to the first editing task information, including the following steps D1-D2:

[0099] Step D1: Iterate through and obtain the reference function module data in the second editing task information and the reference function module data in the first editing task information, and compare them item by item. The second editing task information and the first editing task information include reference function module data of the same type. The second editing task information and the first editing task information are configured to use the same type of reference function attribute field to describe the same reference function module data.

[0100] Step D2: Based on the item-by-item comparison results of the reference functional module data in the second editing task information and the reference functional module data in the first editing task information, determine the data change results between the second editing task information and the first editing task information.

[0101] See Figure 4The process iterates through the second and first editing task information, which describe the editing results of the target editing task under different editing states. Iteration means checking and retrieving each reference function module data (SubModel) in the second and first editing task information one by one. Reference function module data can be understood as the data of each functional part that makes up the editing task. For example, in image editing, it may include color adjustment module data, filter module data, cropping module data, etc.; in video editing, it may include video clip module data, special effects module data, transition module data, etc. Optionally, each reference function module data in the editing task information is configured with a reference function attribute field for description. The reference function attribute field is used to describe the attribute field of the editing function used in the video and audio materials.

[0102] Furthermore, these two editing task information entries are configured to use the same type of reference function attribute fields to describe the same reference function module data. This means that the description method for the same function module is consistent across different editing states; both editing task information entries use the same attribute fields to describe its characteristics, only the resulting values ​​differ. For example, for the "audio adjustment" function module, attribute fields such as "volume" and "pitch" might be used to describe its state. During the traversal, each reference function module data entry in the second editing task information is compared with its corresponding entry in the first editing task information, yielding comparison results for each reference function module data entry. These results can be completely identical, partially identical, or completely different. The comparison content includes, but is not limited to, the module's parameter values ​​and status flags.

[0103] See Figure 4 If there are discrepancies in the data of a certain reference functional module between the two editing task information, these discrepancies will be recorded and used as part of the data change result between the second and first editing task information. For example, if the intensity value of a filter changes in the second editing task information, this change will be recorded to describe the change from the first to the second editing state. In other words, based on the results of item-by-item comparison, the overall information change result between the second and first editing task information is comprehensively analyzed and determined. This information change result can clearly show what specific changes have occurred from the first to the second editing state. Finally, by integrating the comparison results of all reference functional module data, the complete data change result between the second and first editing task information is obtained.

[0104] By using the above method, and comparing reference function module data of the same type item by item, and describing them using reference function attribute fields of the same type, the specific changes from the first editing state to the second editing state can be determined very accurately. Furthermore, after determining the data change results, only these changed parts can be stored, rather than the entire editing task's data, which greatly saves storage space.

[0105] S350. If the information change result of the second editing task information relative to the first editing task information is that an information change has occurred, then based on the difference in editing task information caused by the information change between the second editing task information and the first editing task information, the second editing state of the target editing task is stored as a draft.

[0106] See Figure 4 To determine whether the information in the second editing task has changed compared to the information in the first editing task, this is done by comparing the data of various reference functional modules in the two editing task information. If any difference is found in the data of any reference functional module, it is considered that an information change has occurred. For example, in an image editing task, the image color parameters, filters, etc. in the first editing state are compared with the corresponding parameters in the second editing state. If any item is different, it indicates that an information change has occurred.

[0107] Optionally, by recursively traversing and comparing the values ​​of the functional attribute fields in the reference functional module data of the second editing task information with those in the first editing task information, any subtle changes in the second editing task information relative to the first editing task information can be detected very accurately.

[0108] See Figure 4 If the information change result of the second editing task information relative to the first editing task information is a change in information, it is necessary to determine the difference in editing task information caused by the information change between the second and first editing task information. This difference refers to the specific changes that occur from the first editing state to the second editing state. For example, in video editing, this may include specific changes such as adding new video clips or adjusting the parameters of a special effect. By analyzing the two editing task information, these differences can be accurately determined. If the information change result of the second editing task information relative to the first editing task information is no change in information, then a draft is not stored for the second editing state of the target editing task.

[0109] Based on the determined differences in editing task information, a draft is stored for the second editing state of the target editing task. This means that only the differences in editing task information from the first to the second editing state are stored, rather than storing all the data of the second editing task information corresponding to the second editing state. For example, in audio editing, if the only change from the first to the second editing state is adjusting the volume, then when storing the draft, only the volume change value needs to be recorded, not the entire audio file and all editing settings.

[0110] By adopting the above scheme, only the differences in editing task information are stored, significantly reducing the amount of data stored. For large multimedia editing tasks, this can save a significant amount of storage space and improve storage efficiency. Especially in situations involving frequent editing operations, it avoids repeatedly storing large amounts of the same data. When it is necessary to restore the draft, the restoration process can be much faster because only the differences are stored. The system can first load the draft from the first editing state, and then quickly update it based on the differences to restore it to the second editing state.

[0111] As an optional but not limited implementation, the second editing state of the target editing task is stored as a draft based on the difference between the second editing task information and the first editing task information, including the following steps E1-E2:

[0112] Step E1: Based on the difference in editing task information between the second editing task information and the first editing task information, generate draft status description information for the target editing task when it is in the second editing state. The draft status description information is used to indicate the reference function module data that has changed in the draft of the target editing task in the second editing state relative to the draft of the target editing task in the first editing state.

[0113] Step E2: Store the draft status description information of the target editing task when it is in the second editing state.

[0114] After determining the differences between the second and first editing task information, the difference is used to generate a draft state description for the target editing task in the second editing state. This difference represents the changes from the first to the second editing state. The draft state description information indicates the reference functional module data that shows changes in the draft of the target editing task in the second editing state relative to the draft of the target editing task in the first editing state. For example, if a new video clip is added or the color saturation is adjusted in video editing, the draft state description information will record these changed functional module data.

[0115] By storing only the draft state description information, rather than all the data from the second editing state, storage requirements are significantly reduced. For large multimedia editing tasks or situations involving frequent editing, this approach can save substantial storage space and improve storage efficiency. When it's necessary to revert to the second editing state, it can be quickly reconstructed based on the stored draft state description information and the data from the first editing state. Because only the changed parts need to be processed, rather than the entire task's data, the recovery speed is much faster.

[0116] Draft status descriptions serve as crucial information for version control. By viewing the status descriptions of different draft versions, one can clearly understand the changes in each version, facilitating version comparison and selection. Furthermore, it allows for reverting to a specific version's editing state as needed. The generated draft status descriptions are then stored so that, when required, they can be combined with the first editing task information from the first editing state to revert to the second editing state or view the editing history. The storage method can be a local database, a file system, or cloud storage, depending on the application's needs.

[0117] As an optional but not limited implementation, the draft storage when the target editing task is in the second editing state is to store the data of each reference functional module in the form of a database table, and the data of different reference functional modules are stored in separate columns, with each reference functional module data corresponding to a column of the database table.

[0118] The draft of the target editing task in its second editing state is stored in a database table structure. This means that various information of the editing task is organized into a table format in the database according to certain rules. For example, SQLite is a lightweight embedded relational database management system. For instance, in a multimedia editing task, a database table can be created to store draft status description information. For each version of the editing state, each column corresponds to different reference functional module data. Different reference functional module data within the same version of the editing state are stored in separate columns; that is, each reference functional module data is stored in a column of the database table. This makes the data structure clearer.

[0119] The technical solution of this disclosure, by determining the first editing task information associated with the first editing state and the second editing task information associated with the second editing state, can accurately capture the editing state of the target editing task at different stages. For multimedia material editing tasks, this means that it can record in detail the specific situation of each editing task from the initial editing state to the subsequent further editing state. When the target editing task in the second editing state triggers draft storage, the draft content is determined according to the difference between the editing task information of the second editing task and the first editing task. It is not necessary to repeatedly store the editing task information already in the first editing state to describe the draft content. Only the changes from the first editing state to the second editing state need to be recorded, which greatly reduces the amount of data to be stored. This differential storage method also speeds up the storage speed. Especially when frequent editing operations are performed and drafts need to be stored at any time, the smoothness of creation will not be affected by the long storage process. Since the draft is determined based on the difference in editing task information, when the draft needs to be restored, the target editing task can be quickly restored to a specific editing state. This is because only the information of the difference needs to be processed, rather than all the data of the entire editing task, which reduces the errors and confusion that may occur during the data restoration process.

[0120] Figure 5 This is a schematic diagram of the structure of a multimedia material editing and processing device provided in an embodiment of the present disclosure. The embodiments of the present disclosure are applicable to the situation of saving drafts during the editing process of multimedia materials. The multimedia material editing and processing device can be implemented in the form of software and / or hardware, and is generally integrated on any electronic device with network communication function, such as a mobile terminal, PC, or server.

[0121] like Figure 5 As shown, the multimedia material editing and processing apparatus of this disclosure embodiment may include the following:

[0122] The first determining module 510 is used to determine the first editing task information associated with the first editing state. The first editing state is the initial editing state when the target editing task is just triggered.

The target editing task is a multimedia material editing task.

[0138] Based on the above embodiments, optionally, the second editing state of the target editing task is stored as a draft, including:

[0139] If the draft associated with the target editing task has already been stored in the local storage device, the second editing task information is compared with the first editing task information to determine the information change result of the second editing task information relative to the first editing task information.

[0140] If the information change result of the second editing task information relative to the first editing task information is that an information change has occurred, then the second editing state of the target editing task is stored as a draft based on the editing task information difference caused by the information change between the second editing task information and the first editing task information.

[0141] Based on the above embodiments, optionally, the second editing task information is compared with the first editing task information to determine the information change result of the second editing task information relative to the first editing task information, including:

[0142] The reference function module data in the second editing task information is retrieved and compared with the reference function module data in the first editing task information. The second editing task information and the first editing task information include reference function module data of the same type. The second editing task information and the first editing task information are configured to use the same type of reference function attribute field to describe the same reference function module data.

[0143] Based on the item-by-item comparison results between the reference functional module data in the second editing task information and the reference functional module data in the first editing task information, the data change results between the second editing task information and the first editing task information are determined.

[0144] Based on the above embodiments, optionally, the second editing state of the target editing task is stored as a draft according to the difference between the second editing task information and the first editing task information, including:

[0145] Based on the difference in editing task information between the second editing task information and the first editing task information, a draft status description information is generated for the target editing task when it is in the second editing state. The draft status description information is used to indicate the reference function module data that has changed in the draft of the target editing task in the second editing state relative to the draft of the target editing task in the first editing state.

[0148] The technical solution of this disclosure, by determining the first editing task information associated with the first editing state and the second editing task information associated with the second editing state, can accurately capture the editing state of the target editing task at different stages. For multimedia material editing tasks, this means that it can record in detail the specific situation of each editing task from the initial editing state to the subsequent further editing state. When the target editing task in the second editing state triggers draft storage, the draft content is determined according to the difference between the editing task information of the second editing task and the first editing task. It is not necessary to repeatedly store the editing task information already in the first editing state to describe the draft content. Only the changes from the first editing state to the second editing state need to be recorded, which greatly reduces the amount of data to be stored. This differential storage method also speeds up the storage speed. Especially when frequent editing operations are performed and drafts need to be stored at any time, the smoothness of creation will not be affected by the long storage process. Since the draft is determined based on the difference in editing task information, when the draft needs to be restored, the target editing task can be quickly restored to a specific editing state. This is because only the information of the difference needs to be processed, rather than all the data of the entire editing task, which reduces the errors and confusion that may occur during the data restoration process.
