[0012] To further clarify the purpose, technical modes and advantages of the embodiments of this disclosure, the technical modes of the embodiments of this disclosure will be described clearly and completely below with reference to the drawings of the embodiments of this disclosure. It is clear that the embodiments described are only a part of the embodiments of this disclosure, and not all of them. All other embodiments that can be obtained by a person skilled in the art without creative effort based on the embodiments of this disclosure are also within the scope of this disclosure.

[0013] In conventional technology, the video editing process on terminal devices takes a long time, especially the video encoding and export processes, resulting in long waiting times for users to export the video, which has a serious impact on the user experience.

[0014] To solve the technical problems described above, this disclosure considers that when a user derives a video editing draft as a video, they typically need to enter the video editing draft's derivation interface. The derivation parameters set in the derivation interface include, but are not limited to, the video file name, derivation path, resolution, bitrate, encoding format, and video container format (file package format). Users generally remain in the derivation interface for a certain period of time. For most users, it is not common to frequently modify most of the derivation parameters within the derivation interface. Because users have certain usage habits for most of the derivation parameters, even if they are modified, the modified derivation parameters, such as the video file name and derivation path, may not affect the derivation product and may not affect the video encoding. Therefore, this idle time can be fully utilized to start the derivation of the video editing draft early in the background based on the historical derivation parameters. That is, when a user opens the video editing draft's derivation interface, simply by responding to the command to open the derivation interface, the pre-derivation process for the video editing draft can be started based on the historical derivation parameters. Because the pre-derivation process runs in the background, the user is unaware of it, and can continue to modify one or more derivation parameters in the derivation interface. This allows the pre-derivation process to be reused when the user triggers a derivation control within the derivation interface, reducing the time the user has to wait for derivation, improving the derivation speed the user perceives, and enhancing the user experience of the derivation process.

[0015] The video derivation method provided in this disclosure is applicable to electronic devices such as terminal devices or servers, and as shown in Figure 1, using a terminal device as an example, the user opens the video editing draft derivation interface.

[0016] Furthermore, user information (including, but not limited to, user device information and user personal information) and data (including, but not limited to, analytical data, storage data, and display data) relating to this application are all information and data authorized by the user or the relevant parties. The collection, use, and processing of related data must comply with the laws and standards of the relevant countries and regions, and a corresponding operating interface will be provided to allow the user to choose or refuse authorization.

[0017] The video derivation method of this disclosure will be described in detail below based on specific examples.

[0018] Referring to Figure 2, which is a flowchart of a video derivation method provided by one embodiment of the present disclosure. The method of this embodiment is applicable to electronic devices such as terminal devices or servers, and the video derivation method includes the following steps.

[0019] In S201, in response to a command to jump to the video editing draft derivation interface, the video editing draft is derived based on the history derivation parameters, and the first video is generated.

[0020] In this embodiment, in some video editing scenarios (such as video editing applications), a video editing draft includes one or more multimedia materials such as original video materials (one or more), pixel materials, audio materials, etc. and editing information for the multimedia materials. The process of deriving a video encoding draft is a video encoding process, that is, these multimedia materials are synthesized into one video. When deriving the video editing draft as a video, usually, it is necessary to enter the derivation interface of the video editing draft. The derivation parameters set in the derivation interface include, but are not limited to, video file name, derivation path, resolution, bit rate, encoding format, video container format (file package format), etc. Usually, the user stays at the derivation interface for a certain period of time. For most users, usually, most of the derivation parameters in the derivation interface are not frequently modified. Even if modifications are made, the modified derivation parameters, such as the video file name, derivation path, etc., may not affect the derivation product. Therefore, in this embodiment, such idle time is fully utilized, and based on the historical derivation parameters, the derivation of the video editing draft is started early in the background. That is, when the user opens the derivation interface of the video editing draft, just in response to the command to jump to the derivation interface of the video editing draft, based on the historical derivation parameters, the derivation process of the video editing draft is started, and the first video corresponding to the video editing draft is generated. The derivation process is executed in the background without the user's perception, and the user can continue to modify one or more derivation parameters in the derivation interface.

[0021] Optionally, since the derivation interface can save the historical derivation parameters at the previous derivation, based on the historical derivation parameters at the previous derivation in the derivation interface, the derivation process of the video editing draft can be started early.

[0022] In S202, in response to a trigger instruction of a derivation control in the derivation interface, obtain the current derivation parameters in the derivation page.

[0023] In this embodiment, the user can modify one or more derivation parameters in the derivation interface. After the modification is completed, trigger a derivation control (for example, a derivation button) in the derivation interface, and in response to the trigger instruction of the derivation control, the current derivation parameters in the derivation page can be obtained.

[0024] In S203, when the target derivation parameter in the current derivation parameter matches the target derivation parameter in the historical derivation parameter, adopt the first video and the target video derived from the video editing draft as the target video.

[0025] In this embodiment, after obtaining the current derived parameters within the derived page, the current derived parameters are compared with the historical derived parameters. Since modifications to some derived parameters affect the derived product, while modifications to some parameters do not affect the derived product, when comparing the current derived parameters with the historical derived parameters, it is only possible to determine whether the target derived parameters in the current derived parameters match the target derived parameters in the historical derived parameters. The target derived parameters are those that affect the derivation result and include, but are not limited to, resolution, bitrate, and encoding format. Selectively, modifications to the video container format (file package format) may or may not affect the derivation result. In scenarios where modifications to the video container format (file package format) affect the derivation result, the target derived parameters include the video container format (file package format). In scenarios where modifications to the video container format (file package format) do not affect the derivation result, the target derived parameters do not include the video container format (file package format). Modifications to derivation parameters such as video file names and derivation paths do not affect the derivation results, and therefore are not treated as target derivation parameters and are excluded from the comparison.

[0026] If the target derived parameter in the current derived parameters is determined to match the target derived parameter in the history derived parameters, the target derived parameter is not modified, and the derivation result is not affected. That is, the first video derived from the video editing draft based on the history derived parameters matches the second video derived from the video editing draft based on the current derived parameters. Therefore, when the derivation control is triggered, there is no need to derive the video editing draft from the beginning, and the final first video can be directly adopted as the target video derived from the video editing draft. This makes it possible to make full use of the idle time the user is in the derivation interface, reduce the time the user has to wait for derivation, and improve the user experience of the derivation process.

[0027] When a trigger command for the derivation control within the derivation interface is selectively received, the first video derivation process may be in execution, completed, or, of course, may have failed or be in any other state. Therefore, in this embodiment, it is possible to detect the state of the first video derivation process when a trigger command for the derivation control within the derivation interface is received.

[0028] Furthermore, in S203, adopting the first video as the target video derived from the video editing draft specifically includes, if the derivation process for the first video is in progress, continuing to run the derivation process for the first video until the execution of the derivation process for the first video is completed, displaying derivation progress information, and adopting the first video as the target video derived from the video editing draft.

[0029] In this embodiment, when a trigger command for the derivation control in the derivation interface is received, if the derivation process for the first video is in progress, there is no need to restart the normal derivation process. Rather, the derivation process for the first video continues to run until it finishes, the derivation process for the first video is reused, and derivation progress information, which is progress information for the derivation process for the first video, is displayed. The first video obtained after the execution of the first video derivation process is completed is a video file based on history derivation parameters, and this video file is adopted as the target video derived from the video editing draft.

[0030] After the first video derivation process has started, it is possible to record the progress information of the first video derivation process. When a trigger command for the derivation control in the derivation interface is received, the derivation progress display interface is displayed, and the progress information of the first video derivation process is displayed on the derivation progress display interface.

[0031] In another case, when a trigger command for the derivation control in the derivation interface is received, the execution of the first video derivation process has already finished, and derivation completion prompt information, such as the derivation completion prompt interface, is displayed directly. Furthermore, there is no need to restart the normal derivation process, and the first video obtained after the execution of the first video derivation process has finished can be adopted as the target video derived from the video editing draft.

[0032] If it is determined that the target derived parameter in the current derived parameter does not match the target derived parameter in the history derived parameter, a re-derivation of the video editing draft is performed based on the current derived parameter. If the pre-derivation process is running, the derivation process for the first video is terminated and the first video is deleted. If the execution of the derivation process for the first video has finished, the first video is deleted directly.

[0033] According to the video derivation method provided in this embodiment, in response to a command to jump to the video editing draft derivation interface, the video editing draft is derived based on the history derivation parameters, a first video is generated, and in response to a trigger command of the derivation control in the derivation interface, the current derivation parameters in the derivation page are obtained, and if the target derivation parameter in the current derivation parameters matches the target derivation parameter in the history derivation parameters, the first video is adopted as the target video derived from the video editing draft. When the derivation page is opened, the video editing draft derivation is started early, making full use of the idle time the user is in the derivation interface, reducing the time the user has to wait for derivation, and improving the user experience of the derivation process.

[0034] Based on any of the above embodiments, in S201, when deriving the video editing draft based on the history derivation parameters, a target folder is created in the corresponding storage area based on the history derivation path in the history derivation parameters, and the derivation process of the first video of the video editing draft is started based on the history derivation parameters. The first video in the derivation process is cached in the target folder, and the target folder may be a non-hidden folder or a hidden folder. By using a hidden folder, the user may not be aware of the derivation process of the first video, and it is possible to avoid failure of the derivation process of the first video due to deletion of the target folder by user error.

[0035] Furthermore, after the execution of the first video derivation process is complete, if the first video obtained after the execution of the first video derivation process is to be adopted as the target video derived from the video editing draft, the user may modify the derivation path in the derivation interface. Therefore, the first video is moved from the target folder mentioned above to the current derivation path in the current derivation parameters and adopted as the target video derived from the video editing draft.

[0036] Furthermore, if the user modifies other derivation parameters (not those mentioned above) that do not belong to the target derivation parameters in the derivation interface, the first video obtained after the execution of the first video derivation process is completed can be adjusted based on these other derivation parameters. For example, if the user modifies the video file name in the derivation interface, the video file name for the first video will be modified based on the modified video file name.

[0037] Based on any of the above embodiments, in S202, after obtaining the current derivation parameters in the derivation page, if a failure in the first video derivation process or deletion of the first video is detected, the video editing draft is directly re-derivated based on the current derivation parameters.

[0038] In this embodiment, after starting the first video derivation process, there is a possibility of failure occurring or the product of the first video derivation process being deleted. When a trigger command of the derivation control in the derivation interface is received, it is possible to detect whether the first video derivation process has failed or whether the product of the first video derivation process has been deleted. If it is detected that the first video derivation process has not failed and the product of the first video derivation process has not been deleted, it is possible to further determine whether the target derivation parameter in the current derivation parameter in the derivation interface matches the target derivation parameter in the history derivation parameter. If it is detected that the first video derivation process has failed or the first video has been deleted, the video editing draft can be directly re-derived based on the current derivation parameter. In the case where the first video derivation process has failed and the product of the first video derivation process has not been deleted, the generated first video can be deleted.

[0039] Based on any of the embodiments described above, if, after obtaining the current derived parameters in the derived page, S202 detects that the current derived path in the current derived parameters and the path where the first video resides are not on the same disk partition, the video editing draft is further re-derived directly based on the current derived parameters.

[0040] In this embodiment, although modifying the derived path does not affect the derivation result, if the current derived path in the current derived parameters and the path where the first video resides are not on the same disk partition, it may take a long time to move the first video to another partition after the execution of the first video derivation process is completed. Therefore, if it is detected that the current derived path in the current derived parameters and the path where the first video resides are not on the same disk partition after receiving a trigger command for the derivation control in the derivation interface, the video editing draft is directly re-derived based on the current derived parameters. Of course, the detection process of whether the current derived path in the current derived parameters and the first video are on the same disk partition can also be performed after obtaining the current derived parameters in the derivation page in S202.

[0041] Based on any of the above embodiments, after initiating the first video derivation process for a video editing draft, the user may modify any target derivation parameter before receiving a trigger command for the derivation control in the derivation interface. If the video editing draft derivation process is restarted based on the current derivation parameter after receiving a trigger command for the derivation control in the derivation interface, some idle time may be wasted. For example, if the user first modifies a target derivation parameter, which is the derivation interface, and then remains in the derivation interface for a long time to trigger the derivation control in the derivation interface, the idle time between the modification of the target derivation parameter and the triggering of the derivation control in the derivation interface is wasted. Therefore, in this embodiment, if a modification of any target derivation parameter in the derivation interface is detected after initiating the first video derivation process for a video editing draft, but before receiving a trigger command for the derivation control in the derivation interface, the first video derivation process is stopped, and the video editing draft is re-derived based on the history derivation parameter and the modified target derivation parameter. In other words, each time a modification to the target derivation parameter is detected, the derivation process for the first video is stopped, the derivation process is restarted, and the effective use of idle time is ensured. More specifically, the target derivation parameter in the history derivation parameter is replaced with the modified target derivation parameter, the replaced derivation parameter is obtained, and the video editing draft derivation process is restarted based on the replaced derivation parameter.

[0042] Based on any of the above embodiments, as shown in Figure 3, S201, which derives the video editing draft based on the history derivation parameters, further includes S2011, which determines whether the current state satisfies a preset derivation activation condition based on a preset detection strategy, and S2012, which, if it is determined that the current state satisfies the preset derivation activation condition, derives the video editing draft based on the history derivation parameters.

[0043] In this embodiment, it is possible to determine in advance whether the current state satisfies the pre-set derivation start conditions before starting the pre-derivation process. If it is determined that the current state does not satisfy the pre-set derivation start conditions, the pre-derivation process is not started. When the derivation control in the derivation interface is triggered, the system responds to the trigger command of the derivation control and starts the normal derivation process for the video editing draft based on the current derivation parameters in the derivation interface. If it is determined that the current state satisfies the pre-set derivation start conditions, the system starts the pre-derivation process for the video editing draft based on the history derivation parameters.

[0044] When selectively determining whether the current state satisfies pre-defined derivation and activation conditions based on a pre-defined detection strategy, the pre-defined detection strategy may include one or more of the following detection items.

[0045] 1) Detect whether the execution of the target draft editing algorithm has finished. The target draft editing algorithm includes, but is not limited to, frame interpolation algorithms, image stabilization algorithms, and keying algorithms. Whether it is pre-derivation or a normal derivation process, it must be performed after the execution of these algorithms has finished. When a command to open the video editing draft derivation interface is received, if the execution of the target draft editing algorithm has not finished, the pre-derivation process will not start until the execution of the target draft editing algorithm has finished. At this time, if a trigger command for the derivation control in the derivation interface has not yet been received, the pre-derivation process will be started, or, after a trigger command for the derivation control in the derivation interface is received, the normal derivation process for the video editing draft will be started based on the current derivation parameters in the derivation interface.

[0046] 2) Detect whether the current device's processing power meets the maximum load pressure of the pre-extraction process. The purpose of this detection is to minimize user awareness of the pre-extraction process and avoid affecting the user's normal editing experience. If the current device's processing power does not meet the maximum load pressure of the pre-extraction process, the pre-set export start conditions will not be met.

[0047] It is possible to selectively pre-set the processing power corresponding to any device, and this processing power is the pre-set load pressure threshold for the pre-export process for any device. For example, the pre-set load pressure threshold for model 1 is 3840*2160 (4K), and the pre-set load pressure threshold for model 2 is 3840*2160*2 (8K). The pre-set load pressure threshold is related to the performance of the device hardware (e.g., GPU), and the higher the performance of the device hardware, the higher the pre-set load pressure threshold. For the maximum load pressure in the pre-export process of the video editing draft, the maximum resolution of each track in the video editing draft is obtained, the sum of the maximum resolutions of each track is calculated, and the sum of the maximum resolutions of each track is determined as the maximum load pressure of the pre-export process. For example, if the video editing draft shown in Figure 4 contains three tracks, with a maximum resolution of 1080*1920 for track 1, 1280*720 for track 2, and 3840*2160 for track 3, the maximum load pressure will be 1080*1920 + 1280*720 + 3840*2160. Then, the maximum load pressure of the pre-extraction process is compared with the preset load pressure threshold of the current device. If the maximum load pressure of the pre-extraction process exceeds the preset load pressure threshold, it is determined that the processing capacity of the current device does not meet the maximum load pressure of the pre-extraction process. For example, if the current device is model 1 and the corresponding preset load pressure threshold is 3840*2160 (4K), the maximum load pressure of the pre-extraction process of the video editing draft shown in Figure 4 exceeds the preset load pressure threshold of the current device, and it is determined that the processing capacity of the current device does not meet the maximum load pressure of the pre-extraction process, i.e., the preset derivation start condition is not met.

[0048] 3) Detect whether or not there are access rights to the target path of the pre-extraction process's output. In the above embodiment, the output of the pre-extraction process is cached in the storage area where the history output path exists, or output to an arbitrarily specified output path; therefore, both are referred to here as the target path of the pre-extraction process's output. If there are no access rights to the target path of the pre-extraction process's output, the output obtained after the pre-extraction process has finished cannot be accessed or moved, and the output obtained after the pre-extraction process has finished cannot be used as the target video output from the video editing draft. Therefore, it is necessary to detect whether or not there are access rights to the target path of the pre-extraction process's output before starting the pre-extraction process.

[0049] 4) The system detects whether the storage area of ​​the target path for the pre-extraction process's products satisfies the caching requirements for the pre-extraction process's products. Specifically, this includes whether the storage area of ​​the target path for the pre-extraction process's products is sufficient and can accommodate the pre-extraction process's products, and may also include whether the maximum size of a single file allowed by the storage area of ​​the target path for the pre-extraction process's products can accommodate the pre-extraction process's products. If the pre-extraction process's products cannot be accommodated, the system fails to satisfy the caching requirements for the pre-extraction process's products, i.e., it fails to satisfy the pre-configured derivation start conditions.

[0050] 5) Detect whether the materials in the video editing draft are valid. For example, detect whether the materials are missing, whether access permissions exist, and whether there are any problems preventing them from being opened due to abnormal conditions.

[0051] 6) The system detects whether member material (VIP material) is used in the video editing draft and whether the current account is a member account (VIP account). If member material is used in the video editing draft and the current account is not a member account, the material becomes unavailable and pre-export cannot be started. The system can optionally prompt the user to purchase a VIP account or modify the material. If the current account is a member account, the pre-configured export activation conditions are met.

[0052] Based on any of the above embodiments, it is possible to manage the state of the first video extraction process (the state of the pre-extraction process). Specifically, 1) if the pre-set extraction startup conditions are not met, the deployment state is "pre-extraction process unavailable", 2) when the pre-extraction process starts, the deployment state is "pre-extraction process running", 3) when the pre-extraction process fails midway, the deployment state is "pre-extraction process failed", and 4) when the execution of the pre-extraction process is completed, the deployment state is "pre-extraction process successful".

[0053] When a trigger command for the derivation control in the derivation interface is received, the status of the pre-derivation process can be obtained. If the status is pre-derivation process unavailable or pre-derivation process failed, the video editing draft is re-derived based on the current derivation parameters in the derivation interface. If the status is pre-derivation process running, the first video derivation process continues to run until the execution of the first video derivation process is completed, the first video derivation process is reused, derivation progress information is displayed, and the first video is adopted as the target video derived from the video editing draft. If the status is pre-derivation process successful, derivation completion prompt information is displayed directly, and the first video is directly adopted as the target video derived from the video editing draft.

[0054] Based on any of the above embodiments, this embodiment provides a video extraction method, the steps of which are as follows.

[0055] In S401, a command is received to open the video editing draft derivation interface.

[0056] In S402, based on a pre-configured detection strategy, it is determined whether the current state satisfies a pre-configured derived activation condition.

[0057] If it is determined that the current state does not meet the pre-set derivation start conditions, the derivation process will not be started. Instead, after receiving a trigger command from the derivation control in the derivation interface, the normal derivation process will be started for the video editing draft based on the current derivation parameters in the derivation interface. Conversely, if the system does not meet the pre-set derivation start conditions, S403 will be executed.

[0058] In S403, if it is determined that the current state satisfies the pre-set derivation activation conditions, a video editing draft is derived based on the history derivation parameters, and the first video is generated.

[0059] In S404, the system receives a command to modify the derived parameters performed by the user in the derivation interface. Optionally, the user may modify the derived parameters or not. In either case, the user confirms the current derived parameters and then triggers the derivation control within the derivation interface.

[0060] In S405, the trigger command for the derivation control within the derivation interface is received.

[0061] In S406, it is detected whether the first video derivation process has failed or whether the first video has been deleted. If it is detected that the first video derivation process has failed or the first video has been deleted, the video editing draft is directly re-derived based on the current derivation parameters in the derivation interface. If not, S407 is executed.

[0062] In S407, it is detected whether the target derived parameter in the current derived parameter within the derived interface matches the target derived parameter in the history derived parameter. If it is determined that the target derived parameter in the current derived parameter does not match the target derived parameter in the history derived parameter, the video editing draft is directly re-derived based on the current derived parameter within the derived interface, the derivation process for the first video is canceled, and the first video is deleted. If the opposite is true, S408 is executed.

[0063] In S408, it is detected whether the current derivation path in the current derivation parameters and the path where the first video resides are on the same disk partition. If it is determined that the current derivation path in the current derivation parameters and the path where the first video resides are not on the same disk partition, the video editing draft is directly re-derived based on the current derivation parameters in the derivation interface, the derivation process for the first video is canceled, and the first video is deleted. If the opposite is true, S409 is executed.

[0064] In S409, the first video is selected as the target video derived from the video editing draft. Specifically, if the first video derivation process is in progress, the first video derivation process continues until it is completed, derivation progress information is displayed, and the first video is selected as the target video derived from the video editing draft. Alternatively, if the first video derivation process has already been completed, derivation completion prompt information is displayed directly, and the first video is selected as the target video derived from the video editing draft.

[0065] Furthermore, this may further include moving the first video from the current path to the current derived path within the current derived parameters, and further including performing other processes on the first video, such as modifying the video file name, based on the current video file name within the current derived parameters.

[0066] Corresponding to the video extraction method of the above embodiment, Figure 5 is a structural block diagram of a video extraction device provided by an embodiment of the present disclosure. For the sake of clarity, only the parts relevant to the embodiment of the present disclosure are shown. Referring to Figure 5, the video extraction device 500 includes a pre-extraction unit 501, a determination unit 502, and an extraction unit 503.

[0067] Of these, the pre-derivation unit 501 is used to respond to a command to jump to the video editing draft derivation interface, derive the video editing draft based on the history derivation parameters, and generate a first video.
