[Figure 7]This is a schematic diagram of the structure of the electronic device 700 according to an embodiment of this application. [Modes for carrying out the invention]

[0029] With the development of the internet, the dissemination of multimedia files enriches people's work and lives. Before disseminating multimedia files, people generally use tools with multimedia editing capabilities to edit the original media material. For example, they add stickers, subtitles, background music, etc. to the original media material, or they trim, arrange, etc., of the original multiple materials to obtain a higher quality multimedia file, which they then play.

[0030] In the process of multimedia editing, a multimedia editing page typically displays multiple media segments. For example, referring to the multimedia editing page shown in Figure 1, it may include a title area, a tools area, an editing area, and a player. In the editing area, the first track contains text 1 or sticker 1, the second track contains background music 1 and background music 2, and the third track contains video 1. The title area may display, for example, the name of the multimedia editing tool and / or the name of the multimedia editing task. As shown in Figure 1, the title area may display "Multimedia Editing Tool A: Creating a New Multimedia Editing Task 1". The tools area may include the names of various tools. As shown in Figure 1, the tool names may include "XXXX", "ZZZZ", "AAAA", and "BBBB" as examples. In the embodiment of this application, the tools area may include at least a tool called "My Presets". The player is used to display editing effect screens for various materials, and the editing effect screens are used to reflect the effects of various materials after export. To achieve unified operation of multiple media segments, users can combine multiple media segments to obtain a single composite segment. Many composite segments can be reused repeatedly; for example, segments used at the beginning and / or end of many media files can all use the same composite segment. However, the current method for reusing composite segments requires users to first export the composite segment to be reused from a single multimedia editing task, obtain the corresponding media file, and then import that media file into a newly created multimedia editing task. This method has the following problems.Problem 1 is that user operation is complex; Problem 2 is that when there is a reuse target, the corresponding media files must be exported and imported to match the target, resulting in a lack of flexibility; and Problem 3 is that because reused composite segments are exported as corresponding media files and then imported, it is not possible to re-edit the reused composite segments.

[0031] Based on this, embodiments of the present application provide a method for saving a composite segment, which may include, for example, saving a first draft and editing attribute information of a first composite segment in response to a save operation on the first composite segment in a first multimedia editing task, wherein the editing attribute information is used to instruct editing operations on multiple media segments in the first draft, and displaying the first composite segment in accordance with the editing attribute information and the first draft on a page corresponding to a second multimedia editing task in response to a call operation on the first composite segment in a second multimedia editing task.

[0032] In this way, in a single multimedia editing task, content related to a potentially reusable composite segment is saved in the draft corresponding to that multimedia editing task, and in another multimedia editing task, the user can retrieve the content corresponding to the composite segment by calling the composite segment and display the composite segment on the page corresponding to the multimedia editing task based on the retrieved content. The user can also import the exported results when reusing the composite segment without having to individually composite and export multiple media segments related to the composite segment, thereby greatly simplifying the process and workload for reusing composite segments in multimedia editing work and improving the efficiency of user reuse of composite segments, thus providing convenience for users to achieve rapid multimedia editing.

[0033] Taking the multimedia editing page shown in Figure 1 as an example, if the page corresponds to multimedia editing task 1, the user performs a composite operation on text 1 (or sticker 1), background music 1, background music 2, and video 1 according to the method of the embodiment of this application to obtain a composite segment 1 to be displayed on track n. Next, the user saves the composite segment 1 to "My Presets" and saves content related to the composite segment 1 in draft 0 corresponding to multimedia editing task 1, corresponding to a tool having multimedia editing functionality, which may include, for example, segment information 1 of the composite segment 1 and draft 1 indicated by the material identifier in segment information 1. In multimedia editing task 2, the user recalls the composite segment (including composite segment 1) saved in "My Presets" and displays the composite segment 1 on the multimedia editing page, that is, adds segment information 1 and draft 1 of the composite segment 1 to draft 2 corresponding to multimedia editing task 2, and the page corresponding to multimedia editing task 2 may display the composite segment 1 according to the editing attribute information in segment information 1 and draft 1. Track n may be the first, second, or third track, or any other track other than the first, second, and third tracks. Here, Draft 1 may be considered a subdraft of Draft 0 and Draft 2 in two multimedia editing tasks, respectively. Draft 1 contains segment information corresponding to text 1 (or sticker 1), background music 1, background music 2, and video 1, and the editing attribute information contained in segment information 1 is used to instruct editing operations that are uniformly applied to text 1 (or sticker 1), background music 1, background music 2, and video 1, such as speeding up, displacement, trimming, etc.

[0034] The entity implementing the method for saving the composite segment may be a composite segment saving device according to the embodiment of this application. The composite segment saving device may be mounted on an electronic device or a functional module of an electronic device. The composite segment saving device may also be a functional module in a tool having multimedia editing capabilities (e.g., a multimedia editing client or website) that can implement the composite segment saving function according to the embodiment of this application.

[0035] Figure 2 is a flowchart of a method for storing composite segments according to an embodiment of this application. This method may also be used in a composite segment storage device, which may be, for example, the composite segment storage device 600 shown in Figure 6.

[0036] As shown in Figure 2, the method may include, for example, the following S101 to S102.

[0037] S101, in response to a save operation on a first composite segment in a first multimedia editing task, a first draft and editing attribute information of the first composite segment are saved, and the editing attribute information is used to instruct editing operations on multiple media segments in the first draft.

[0038] Multimedia editing is the process by which a user edits original media material (e.g., video or audio) to obtain a media file for playback. Multimedia editing may include, but is not limited to, editing at least one of the following materials: video, audio, text, or stickers. Multimedia editing is generally achieved by a user performing editing operations in a single multimedia editing task using a tool with multimedia editing capabilities (e.g., a video editing client). The page of a multimedia editing task may refer to the editing page that the tool with multimedia editing capabilities shows to the user in this multimedia editing task. For example, the page corresponding to the first multimedia editing task in S101 is the editing page shown to the user in the first multimedia editing task, and the page corresponding to the second multimedia editing task in S102 is the editing page shown to the user in the second multimedia editing task. The first multimedia editing task and the second multimedia editing task may be the same multimedia editing task or different multimedia editing tasks.

[0039] In a multimedia editing tool, the user may create a new multimedia editing task and open the corresponding multimedia editing page. In response to the creation of the multimedia editing task, the multimedia editing tool generates a project file, which may be called a rough draft (e.g., Draft 0 or Draft 2, or Draft 2 or Draft 3 below). The user may then import multiple media segments into the same or different tracks on the multimedia editing page as needed for editing the multimedia editing task.

[0040] Here, the multiple media segments may include multiple single material segments, and the single material segments may include, but are not limited to, video, audio, text, or stickers. Alternatively, the multiple media segments may include at least one single material segment and at least one composite segment. Alternatively, the multiple media segments may include multiple composite segments. In embodiments of this application, a composite segment may participate in a multimedia editing task as a single material type.

[0041] The user may perform individual editing operations on each multimedia segment on the multimedia editing page. Taking the page corresponding to the first multimedia editing task in S101, which corresponds to the multimedia editing page shown in Figure 1, as an example, if the first track contains character 1, then the second draft corresponding to the first multimedia editing task would be, for example, Second draft { Material pool { Text 1 {Material ID 1: Path 1}, Sticker 1 {Material ID 2: Path 2}, Background music 1 {material id 3:path 3}, Background music 2 {Material ID 4: Path 4}, Video 1 {Material ID 5: Path 5}, Track 1 { Segment 1 corresponding to character 1 {edit attribute information 1, material id: 1}}, Track 2 { Segment 3 corresponding to background music 1 {edit attribute information 3, material id:3}, Segment 4 corresponding to background music 2 {edit attribute information 4, material id: 4}}, Third track { Segment 5 corresponding to Video 1 {Editing attribute information 5, Material id: 5} It may also be expressed as}.

[0042] Here, segment information corresponding to a segment includes editing attribute information and a material identifier (id). Editing attribute information may also be instructions from the user for editing operations on the corresponding segment, and may include, but is not limited to, at least one of the following: start time, end time, trimming, speed doubling, or displacement. The material id is indexed in the material pool and used to obtain the corresponding material from the path by obtaining the path corresponding to the material id. The path may be, for example, a local path or a network path, and if the material is stored locally, the path corresponds to the local path where the material is stored, and if the material corresponds to an online resource, the path corresponds to the online retrieval link for the material, for example, a Uniform Resource Locator (URL) for downloading or pulling the online resource.

[0043] Furthermore, at least two of the multiple media segments must participate in the generation of the composite segment. The number of media segments participating in the generation of the composite segment does not affect the realization of the composite segment generation method. In the following explanation, we will use the example that all of the above multiple media segments in S101 participate in the generation of the composite segment.

[0044] Prior to S101, the method may further include generating a first composite segment in response to composite operations on the plurality of media segments in a first multimedia editing task. As one example, generating a first composite segment may include, for example, generating first segment information corresponding to the first draft and the first composite segment in a second draft corresponding to the first multimedia editing task, wherein the editing attribute information in the first segment information is used to instruct the editing operations on the plurality of media segments in the first draft, and the first material identifier in the first segment information is used to indicate the first draft in the material pool of the second draft.

[0045] Here, in one case, the compound operation may be implemented by a control on a multimedia editing page corresponding to the compound function according to the embodiment of the present application, which may be, for example, a "Compound" button on the multimedia editing page, and the compound operation may correspond to a click on the control, or to the selection of at least two media segments to participate in the compound + a click on the control. In another case, the compound operation may be implemented by a shortcut key on the multimedia editing page, and the compound operation may correspond to the use of the shortcut key, or to the selection of at least two media segments to participate in the compound + the use of the shortcut key.

[0046] Taking the page corresponding to the first multimedia editing task in S101, which corresponds to the multimedia editing page shown in Figure 1, as an example, if the first track contains character 1, then after generating the first composite segment, the second draft corresponding to the first multimedia editing task is, for example, Second draft { Material pool { Text 1 {Material ID 1: Path 1}, Sticker 1 {Material ID 2: Path 2}, Background music 1 {material id 3:path 3}, Background music 2 {Material ID 4: Path 4}, Video 1 {Material ID 5: Path 5}, Draft {Material ID 6: First Draft}, First draft { Material pool {text1{materialid1:path1}, Background music 1 {material id 3:path 3}, Background music 2 {Material ID 4: Path 4}, Video 1 {Material ID 5: Path 5}, Segment 1 corresponding to character 1 {edit attribute information 1, material id: 1}, Segment 3 corresponding to background music 1 {edit attribute information 3, material id:3}, Segment 4 corresponding to background music 2 {edit attribute information 4, material id: 4}, Segment 5 corresponding to Video 1 {editing attribute information 5, material id: 5}, }}, Track 1 { Segment 1 corresponding to character 1 {edit attribute information 1, material id: 1}}, Track 2 { Segment 3 corresponding to background music 1 {edit attribute information 3, material id:3}, Segment 4 corresponding to background music 2 {edit attribute information 4, material id: 4}}, Third track { Segment 5 corresponding to Video 1 {editing attribute information 5, material id: 5}}, Track n{ Composite segment 1 {edit attribute information 6, material id: 6}}, It may also be expressed as}.

[0047] Here, composite segment 1 includes editing attribute information 6 and material ID 6, the editing attribute information 6 may be used to instruct editing operations for each media segment in the first draft indicated by material ID 6, and the editing attribute information 6 may include, for example, start time, end time, trimming, speed doubling, or displacement. Each piece of editing attribute information 6 may correspond to each media segment in composite segment 1 and constitutes a unified limitation for each media segment. Material ID 6 is indexed in the material pool to obtain the first draft, and compared to a single material segment, the material ID in the segment information of a single material segment obtained by indexing in the material pool is a pass, not a draft. The first draft may include at least segment information for each media segment in composite segment 1, and may also include a material pool consisting of materials related to each media segment.

[0048] It can be understood that after generating the first composite segment, the first draft is presented as the first composite segment on the page corresponding to the first multimedia editing task, according to the editing attribute information of the first composite segment, and the multiple media segments are replaced.

[0049] To facilitate the reuse of the first composite segment in other multimedia editing tasks, a save operation may be performed on the first composite segment, saving it as a "My Preset," that is, saving it as special material for use in subsequent multimedia editing tasks.

[0050] In one possible embodiment, the save operation may be implemented by a control corresponding to the preset save function according to the embodiment of the present application on a page corresponding to a first multimedia editing task, which may be, for example, a “Save as Preset” button on the multimedia editing page. The user may click the control to trigger the execution of S101 and save the first draft and editing attribute information of the first composite segment.

[0051] In another possible embodiment, the save operation may be performed by a multimedia editing shortcut key, which the user may use directly to trigger the execution of S101 and save the first draft and editing attribute information of the first composite segment.

[0052] For example, taking the page corresponding to the first multimedia editing task shown in Figure 1 as an example, as shown in Figure 3, a "compound" operation on multiple media segments on page 1 corresponding to the first multimedia editing task may be performed to display compound segment 1 on page 2 corresponding to the first multimedia editing task, and the multiple media segments may then be hidden. Next, on page 2 corresponding to the first multimedia editing task where compound segment 1 is displayed, a "save as preset" operation may be performed, and compound segment 1 may be included in "My Presets" on page 3 corresponding to the first multimedia editing task.

[0053] In one possible embodiment, S101 may include, for example, obtaining a first segment identifier in response to a save operation on a first composite segment in a first multimedia editing task, the first segment identifier being used to indicate first segment information corresponding to the first composite segment, the first segment information including editing attribute information and a first material identifier; then, retrieving the first segment information from a second draft corresponding to the first multimedia editing task based on the first segment identifier, and retrieving the first draft from a material pool of the second draft based on the first material identifier; and then saving the first segment information and the first draft in a preset path for the composite segment. In this way, when it is necessary to save the first composite segment as a "my preset", the content associated with the first composite segment can be accurately retrieved, saved in a preset path, and prepared for subsequent retrieval of the first composite segment.

[0054] Here, if the first composite segment corresponds to composite segment 1 in the second draft above, the first segment identifier may be "composite segment 1" before the above {edit attribute information 6, material id: 6}, the first segment information may correspond to {edit attribute information 6, material id: 6}, and the first material identifier may correspond to material id: 6. Content saved after S101 is, Draft {Material ID 6: First Draft}, First draft { Material pool {text1{materialid1:path1}, Background music 1 {material id 3:path 3}, Background music 2 {Material ID 4: Path 4}, Video 1 {Material ID 5: Path 5}, Segment 1 corresponding to character 1 {edit attribute information 1, material id: 1}, Segment 3 corresponding to background music 1 {edit attribute information 3, material id:3}, Segment 4 corresponding to background music 2 {edit attribute information 4, material id: 4}, Segment 5 corresponding to Video 1 {editing attribute information 5, material id: 5}, } and It may also correspond to composite segment 1 {edit attribute information 6, material id: 6}.

[0055] In one embodiment, in S101, a first draft and first segment information corresponding to a first composite segment are stored, the first segment information including a first material identifier and editing attribute information. Here, storing the first draft may include storing the material for each media segment in the first draft. As one example, to conserve memory resources, before saving each media segment for the first draft, it may be determined whether the media segment is already saved in a preset path of the composite segment. If yes, the media segment is not saved redundantly, and only the path corresponding to the material identifier of the media segment in the first draft is updated. The updated path indicated by the material identifier of the media segment in the first draft is the saved location of the media segment in the preset path of the composite segment. If the media segment is not saved in a preset path of the composite segment, the media segment is saved in a preset path of the composite segment, and the path corresponding to the material identifier of the media segment in the first draft is updated. The updated path indicated by the material identifier of the media segment in the first draft is the saved location of the media segment in the preset path of the composite segment.

[0056] As one example, if the first media segment among the plurality of media segments is already saved in the preset path of the composite segment, the path corresponding to the material identifier corresponding to the first media segment in the first draft is updated, and the path indicated by the material identifier corresponding to the first media segment in the updated first draft is the save location of the first media segment in the preset path of the composite segment. If the second media segment among the plurality of media segments is not saved in the preset path of the composite segment, the second media segment is saved in the preset path of the composite segment, the path corresponding to the material identifier corresponding to the second media segment in the first draft is updated, and the path indicated by the material identifier corresponding to the second media segment in the updated first draft is the save location of the second media segment in the preset path of the composite segment.

[0057] For example, referring to Figure 4, the process of saving the first composite segment as a "My Preset" may include the following: S11, the user clicks "Save as Preset" on the page corresponding to the first multimedia editing task, and based on the first segment identifier of the first composite segment, retrieves the first segment information indicated by the first segment identifier in the second draft corresponding to the first multimedia editing task, and the first draft indicated by the first material identifier in the first segment information, S12, displays a save pending notification, which may include, for example, a save progress bar, notifies the user that the save was successful after the save is complete, S13, compares the first composite with the material already saved in the preset path of the composite segment, S14 determines whether all saves are complete. If media segments related to a segment that need to be saved locally and are not saved in the preset path of the composite segment, save them to the preset path of the composite segment. If all saves are complete, execute S15; otherwise, execute S16. In S15, update the path corresponding to the material identifier of each media segment in the subdraft, save the updated first segment information and the first draft. In S16, notify that the save failed and delete the content in memory related to this "Save as Preset" operation.

[0058] Thus, S101 saves the first composite segment as "My Preset," and the composite segment saving device saves the content associated with the first composite segment (i.e., the first segment information and the first draft), preparing it for reuse in subsequent tasks (for example, in the second multimedia editing task in S102).

[0059] S102, In response to a call operation for the first composite segment in the second multimedia editing task, the first composite segment is displayed on the page corresponding to the second multimedia editing task, according to the editing attribute information and the first draft.

[0060] In one possible embodiment, if the second multimedia editing task and the first multimedia editing task are different multimedia editing tasks, after S101 and before S102, the method may further include: S21, loading a third draft corresponding to the second multimedia editing task in response to a new creation operation for the second multimedia editing task; S22, reading segment information and draft corresponding to at least one stored composite segment, the segment information and draft corresponding to at least one composite segment including first segment information and first draft corresponding to a first composite segment. Thus, S102 may include adding the first segment information and first draft to the third draft in response to a call operation for the first composite segment in the second multimedia editing task, and adding the first composite segment to the page corresponding to the second multimedia editing task according to the editing attribute information in the first draft and first segment information on the corresponding timeline.

[0061] Taking the page corresponding to the first multimedia editing task in S101, which corresponds to the multimedia editing page shown in Figure 1, as an example, if the first track contains character 1, then after saving the first composite segment and calling composite segment 1 in the second multimedia editing task, the third draft corresponding to the second multimedia editing task is, for example, Third draft { Material pool { ... Draft {Material ID x: First Draft}, First draft { Material pool {text1{materialid1:path1}, Background music 1 {material id 3:path 3}, Background music 2 {Material ID 4: Path 4}, Video 1 {Material ID 5: Path 5}, Segment 1 corresponding to character 1 {edit attribute information 1, material id: 1}, Segment 3 corresponding to background music 1 {edit attribute information 3, material id:3}, Segment 4 corresponding to background music 2 {edit attribute information 4, material id: 4}, Segment 5 corresponding to Video 1 {editing attribute information 5, material id: 5}, }}, ... track m{ Composite segment 1 {edit attribute information x, material id: x}}, It may also be expressed as}.

[0062] For example, based on the fact that composite segment 1 is included in "My Presets" on page 3, which corresponds to the first multimedia editing task in Figure 3, multiple composite segments are displayed in "My Presets" on page 4, which corresponds to the second multimedia editing task, and these multiple composite segments include composite segment 1. If the user wants to reuse composite segment 1 on page 4, which corresponds to the second multimedia editing task, they can click the "Recall" button below composite segment 1 and display composite segment 1 on track m of page 5, which corresponds to the second multimedia editing task. In this way, the user can edit composite segment 1 on page 5 again.

[0063] As one example, in S22 above, reading the segment information and draft corresponding to at least one stored composite segment may include, for each of the at least one composite segments, first checking whether the associated content of the composite segment is corrupted, obtaining a first check result, for example, whether the draft corresponding to the composite segment has been deleted or corrupted, or whether the segment information of the composite segment has been deleted or corrupted, and if the first check result indicates that the associated content of the composite segment has not been deleted or corrupted, continuing to check the status of the material included in the draft of the composite segment, obtaining a second check result, and if the second check result indicates that the material included in the draft of the composite segment has been deleted, replaced or modified, updating the draft of the composite segment based on the updated material.

[0064] For example, referring to Figure 5, the process of calling the first composite segment in the second multimedia editing task may include the following: S31, the user creates a new second media editing task in a tool with multimedia editing capabilities and generates a third draft corresponding to the second multimedia task; S32, waits for the third draft to finish loading; S33, starts reading each composite segment in "My Presets," including the first composite segment; S34, for each composite segment in "My Presets," first checks whether the associated content of the composite segment is corrupted and obtains a first check result; if the first check result indicates that the associated content of the composite segment has not been deleted and is not corrupted, continues checking the status of the material included in the draft of the composite segment and obtains a second check result; updates the draft of the composite segment based on the second check result; S35, completes reading each composite segment in "My Presets."

[0065] In one possible embodiment, the call operation may be implemented by a control corresponding to a preset call function according to an embodiment of the present application on a page corresponding to a second multimedia editing task, which may be, for example, a “Call” button on the multimedia editing page. The user may click the control to trigger the execution of S102 and display the first composite segment on the page corresponding to the second multimedia editing task.

[0066] In another possible embodiment, the call operation may be performed by a multimedia editing shortcut key, which the user may use directly to trigger the execution of S102 and display the first composite segment on the page corresponding to the second multimedia editing task.

[0067] In another possible embodiment, the call operation may be implemented by a method such as "dragging" a call-awaited composite segment in "My Presets" on the multimedia editing page, where the user "drags" the "first composite segment" in "My Presets" to track m, triggering the execution of S102 and displaying the first composite segment on the page corresponding to the second multimedia editing task. Track m may be any track on the page corresponding to the second multimedia editing task.

[0068] As one example, the method may further include updating the first composite segment in response to an editing operation on the first composite segment that has been saved, wherein the editing operation may include, for example, at least one of renaming, trimming, or speeding up. When an editing operation is performed on the first composite segment on a page corresponding to a second multimedia editing task, it is necessary to update the editing attribute information related to the editing operation in the segment information corresponding to the first composite segment in the third draft, corresponding to the third draft. Here, the editing operation may be implemented by an editing control or shortcut key corresponding to the page corresponding to the second multimedia editing task. Note that the editing operation on the first composite segment may be performed by the Action layer of a tool that provides multimedia editing functionality.

[0069] Furthermore, if the editing operation is a trimming operation on the first composite segment, the composite segment saving device can prohibit trimming outwards. That is, for a first composite segment with a time length of 10 seconds, the time length of the composite segment obtained after the trimming operation will be a maximum of 10 seconds, and it will not be possible to obtain a segment with a time length greater than 10 seconds.

[0070] As another example, the method may further include, in response to a preview operation on a saved first composite segment, displaying an editing effects screen on the player of the multimedia editing page to embody the exported effects of the first composite segment, corresponding to the first composite segment. Here, the preview operation may be achieved by a preview control or shortcut key corresponding to the page corresponding to the second multimedia editing task, or by clicking the first composite segment in "My Presets". In this way, there is no need to call up the composite segment in "My Presets", and when the composite segment is placed on the timeline, the preview of the composite segment in "My Presets" provides convenience in calling up the appropriate composite segment by understanding the content of the composite segment, making it very user-friendly. Note that the above preview operation may be achieved by the Driver layer rendering the first composite segment based on the first draft and the editing attribute information of the first composite segment.

[0071] Thus, this method allows a user to save content related to a potentially reusable composite segment in a draft corresponding to a multimedia editing task within a single multimedia editing task, and in another multimedia editing task, retrieve the content corresponding to the composite segment by calling the composite segment, and display the composite segment on the page corresponding to the multimedia editing task based on the retrieved content. This eliminates the need for the user to individually composite and export multiple media segments related to the composite segment and then import the exported results when reusing the composite segment, significantly simplifying the process and workload for users to reuse composite segments in multimedia editing work and improving the efficiency of users reusing composite segments, thereby providing convenience for users to achieve rapid multimedia editing.

[0072] Accordingly, the embodiments of this application further provide a composite segment generating apparatus 600. Referring to Figure 6, the apparatus 600 is A save unit 601 is used to save a first draft and editing attribute information of a first composite segment in response to a save operation on a first composite segment in a first multimedia editing task, and the editing attribute information is used to instruct editing operations on multiple media segments in the first draft. In response to a call operation for the first composite segment in a second multimedia editing task, the page corresponding to the second multimedia editing task may include a call unit 602 for displaying the editing attribute information and the first composite segment according to the first draft.

[0073] In one embodiment, the storage unit 601 specifically, In response to a save operation on a first composite segment in a first multimedia editing task, a first segment identifier is obtained, the first segment identifier is used to indicate first segment information corresponding to the first composite segment, and the first segment information includes the editing attribute information and a first material identifier. Based on the first segment identifier, the first segment information is obtained from a second draft corresponding to the first multimedia editing task, Based on the aforementioned first material identifier, retrieve the aforementioned first draft from the aforementioned second draft material pool, It is used to save the first segment information and the first draft in a preset path of a composite segment.

[0074] In one embodiment, the editing attribute information includes at least one of the following: start time, end time, trimming, speed, or displacement.

[0075] In one embodiment, the plurality of media segments include a plurality of single material segments, Alternatively, the plurality of media segments include at least one single material segment and at least one composite segment. Alternatively, the plurality of media segments may include a plurality of composite segments.

If the second media segment among the plurality of media segments is not saved in the preset path of the composite segment, the second media segment is saved in the preset path of the composite segment, the path corresponding to the material identifier corresponding to the second media segment in the first draft is updated, and the path indicated by the material identifier corresponding to the second media segment in the updated first draft is used to be the save location of the second media segment in the preset path of the composite segment.

[0077] In one embodiment, the apparatus 600 is Prior to the call operation for the first composite segment in the second multimedia editing task, a load unit for loading a third draft corresponding to the second multimedia editing task in response to a new creation operation for the second multimedia editing task, The system further includes a reading unit for reading segment information and drafts corresponding to at least one stored composite segment, wherein the segment information and drafts corresponding to the at least one composite segment include first segment information and the first draft corresponding to the first composite segment.

This is used to add the first composite segment to the page corresponding to the second multimedia editing task, according to the editing attribute information and the first draft, along the corresponding timeline.

[0078] As one example, the reading unit specifically, For each of the at least one composite segment, the segment information of the composite segment is checked, and a first check result is obtained to indicate whether or not the segment information of the composite segment is corrupted. If the first check result indicates that the segment information of the composite segment is not corrupted, the material included in the draft of the composite segment is checked, and a second check result is obtained to indicate the condition of the material included in the draft of the composite segment. The results of the second check described above are used to update the draft of the composite segment.
