The embodiments described below with reference to the accompanying drawings are exemplary, only used to explain the embodiments of the present application, and should not be construed as limitations on the embodiments of the present application.

Referring to FIG. 1 , the video processing method according to the embodiment of the present application includes steps 01 , 02 and 03 . Wherein, step 01 is to process the material video to generate a video file. Step 02 is to generate a backup video of the material video when processing the video file, the material video is stored in the first path, the backup video is stored in the second path, and the video file includes the first path and the second path. Step 03 is to read the backup video through the second path to replace the material video when the video file is processed and the material video cannot be read through the first path.

Please refer to FIG. 2 , the terminal 100 according to the embodiment of the present application includes the processor 10 . The terminal 100 can be used to implement the video processing method of the embodiment of the present application, that is, the terminal 100 can be used to implement the above steps 01, 02 and 03. Specifically, the processor 10 can be used to process the material video to generate a video file, and generate a backup video of the material video when processing the video file, the material video is stored in the first path, the backup video is stored in the second path, and the video file includes the first path. and the second path; and when the video file is processed and the material video cannot be read through the first path, the backup video is read through the second path to replace the material video.

In the video processing method and the terminal 100 according to the embodiment of the present application, since the backup video is stored, even if the material video cannot be read during the processing of the video file, the backup video can be read to replace the material video without interruption or Loss of the user's processing operation on the video file, the user experience is better.

Specifically, the terminal 100 may be any terminal such as a mobile phone, a computer, a camera, a tablet computer, a notebook computer, a head-mounted display device, a game console, a smart watch, a smart TV, etc. The description in this specification takes the terminal 100 as a mobile phone as an example for description, and it can be understood that , the specific form of the terminal 100 is not limited to a mobile phone. The processor 10 may be an application processor (Application Processor, AP) of the terminal 100 or any dedicated microprocessor in the terminal 100 .

The processor 10 performs step 01, that is, the processor 10 processes the material video to generate a video file. Specifically, the material video may be any video file stored in the memory 20 of the terminal 100, and the memory 20 may be the cache and/or memory of the terminal 100. For example, the material video is a video stored in a media library or an album, and the material video It may be a video shot by the user with the terminal 100, a video downloaded by the user from a server, a video received through Bluetooth, wifi, etc., or a video stored in the cloud.

The video file may be a file including one or more silhouettes of the material video, one or more thumbnails of the material video, shooting time, shooting location, etc. The user can preview the material video through the information in the video file. If an operation is performed on a video file, the corresponding processing method of the operation can be applied to the material video.

Please refer to FIG. 3. In the example shown in FIG. 3, the video file 21 in FIG. 3a includes the silhouette V11 of the material video, and the user can preview the material video through the silhouette V11. As shown in FIG. 3b, the user can Perform processing, such as adding background music, editing, and adding subtitles to the material video corresponding to the silhouette V11 of the video file.

The processor 10 executes step 02, that is, when processing the video file, a backup video of the material video is generated, the material video is stored in the first path, the backup video is stored in the second path, and the video file includes the first path and the second path.

The execution of step 02 by the processor 10 may be triggered by a predetermined operation of the user. The predetermined operation may be that the user inputs an instruction to confirm that the video file is to be opened, specifically, the user selects the video file and clicks to edit, or the user clicks edit first and then confirms the selection of the video file, or the user opens the video editing APP and imports the video file. When the user does not perform the predetermined operation, the processor 10 may not perform step 02 to save the processing resources of the processor 10 and the storage space of the memory 20 .

The location where the material video is stored is defined as the first path, and the backup video generated according to the material video is stored in the second path. The second path can be any storage space opened up in the memory 20, and the second path is, for example, sdcard/data/ com.coloros.videoeditor/videocache, the second path may be pre-specified by the user, or may be the cache directory of the video editing APP. At the same time, the index relationship between the material video and the backup video can also be stored in the video file, that is, through the index relationship, the location of the backup video can be found according to the request for the material video, and the location of the material video can also be found according to the request for the backup video. Location.

In an example, for one material video, the amount of backup video generated and stored by the processor 10 is one, and the one material video and the backup video can be mutually indexed. In another example, for one material video, the number of backup videos generated and stored by the processor 10 is multiple, and the one material video and the plurality of backup videos can be indexed to each other pairwise.

Please refer to FIG. 3. In the example shown in FIG. 3, FIG. 3b is an interface for opening the video file. When the video file is opened, the silhouette V11 of the material video is displayed on the interface. At the same time, as shown in FIG. 3c, the processor 10 A backup video V12 of the material video is generated and stored in the second path 22 .

The processor 10 executes step 03, that is, when the video file is processed and the material video cannot be read through the first path, the backup video is read through the second path to replace the material video. Wherein, when processing a video file, it means that the user has already started processing the video file and has not finished processing the video file. The material video that cannot be read through the first path may be that the material video has been removed from the original first path, for example, the material video has been completely deleted from the storage 20 or the cloud, or the material video has been moved to the storage 20 or another location in the cloud. under a path.

In the related art, when processing video files, for example, in the process of editing silhouettes, the user may switch to processing other matters in the terminal, and when processing other matters, the material video may be deleted, or the terminal may generate a system The fault causes the material video to be deleted, or the video material in the cloud is deleted by other users. When the user switches to editing the silhouette again, at this time, since the material video has been deleted, the editing will not be carried out normally, and the editing interface may be forced to exit, or the effects such as adding filters and music can be previewed. , but the edited video cannot be finally generated, which leads to the failure of editing, the editing operations that the user spends their time on are lost at the same time, and the user experience is poor.

By implementing step 03, after reading the backup video to replace the material video, the backup video can transfer all the operation requirements for the material video in the process of processing the video file this time to the backup video.

Please refer to FIG. 4. In the example shown in FIG. 4, FIG. 4a shows that when processing the video file, the material video V13 is deleted, and the processor 10 can no longer read the material video V13 through the first path. As shown in FIG. 4b, the processor 10 reads the backup video V12 through the second path 22 to replace the material video V13. If the user inputs a request for the material video V13 in the process of processing the video file, the processor 10 uses the backup Video V12 replaces material video V13 in response to the request.

Of course, if the material video can be read through the first path when processing the video file, it is not necessary to read the backup video to replace the material video.

To sum up, in the video processing method and the terminal 100 according to the embodiment of the present application, since the backup video is stored, even if the material video cannot be read during the process of the video file being processed, the backup video can be read to replace the material video, and the material video can be replaced by the backup video. The user's processing operation of the video file will be interrupted or lost, and the user experience is better.

Referring to FIG. 5, in some embodiments, the video file includes a silhouette of the material video, and the silhouette is associated with the first path and the second path. The video processing method further includes step 04, which is that the first path cannot be read in step 04. After reaching the material video, disassociate the silhouette from the first path. The video editing interface still shows a silhouette when opening a video file through the video editing interface.

Please refer to FIG. 2 , in some embodiments, the processor 10 can also be used to implement step 04, that is, the processor 10 is used to disassociate the silhouette from the first path after the material video cannot be read through the first path . The video editing interface still shows a silhouette when opening a video file through the video editing interface.

Specifically, the silhouette can be a certain frame or multiple frames of the material video. When the user opens the video file through the video editing interface, he can operate the silhouette. The processor 10 records the information of these operations into the video file, and the subsequent processor 10. The material video can be found according to the relationship between the silhouette and the first path, and the material video can be processed accordingly according to the operation information. However, if the material video cannot be read through the first path, the silhouette is disassociated from the first path, and the processor 10 no longer searches for the material video according to the association between the silhouette and the first path, but according to the silhouette and the second path. The associated relationship of the path finds the backup video, and performs corresponding processing on the backup video according to the operation information.

Since the silhouette is included in the video file, the material video cannot be read through the first path, and the silhouette in the video file will not be affected. When opening a video file through the video editing interface, the silhouette is still displayed in the video editing interface, the user will not notice that the material video is deleted, the editing operation can continue, and the editing operation that has been performed can be transferred to the backup video. edits are not lost.

Please refer to Fig. 4. In the example shown in Fig. 4, Fig. 4c shows the video editing interface, in which the silhouette V11 is displayed, and even when the video editing interface has not been closed, the material video V13 is deleted (such as 4a), the video editing interface still displays the silhouette V11, and the user can still edit the silhouette V11 by operating on the video editing interface.

Referring to FIG. 6, in some embodiments, the video processing method further includes step 05. Step 05 is to remove the association between the silhouette and the first path and delete the backup video when the silhouette is deleted in response to a user input.

Referring to FIG. 2 , in some embodiments, the processor 10 may be configured to implement step 05, that is, the processor 10 may be configured to disassociate the silhouette with the first path and delete the backup video when deleting the silhouette in response to a user input.

When the user inputs an instruction and deletes the silhouette, it indicates that the user does not want to process the material video corresponding to the silhouette, then the silhouette is disconnected from the first path, and the backup video is deleted to prevent the backup video from occupying the storage space of the terminal 100 .

In an example, the number of material videos may be multiple, the user may edit multiple silhouettes corresponding to the multiple material videos at the same time, and the editing operation for the multiple silhouettes may be splicing multiple silhouettes. Multiple material videos may be stored in the same first path, or may be stored in different first paths. Corresponding to multiple material videos, the number of backup videos is also multiple, and each backup video is obtained by the processor 10 according to the corresponding material video, and the multiple backup videos can be stored in the same second path.

When editing multiple silhouettes, the user may decide during the editing process that one or more silhouettes no longer need to be edited, and remove the one or more silhouettes from editing, that is, delete the one or more silhouettes, At this time, the user is still editing other silhouettes. When the user confirms that one or more silhouettes need to be removed from editing, the processor 10 may disassociate the one or more silhouettes from the first path, and delete the corresponding one or more backup videos to avoid the one or more backup videos. The video occupies the storage space of the memory 20 . Of course, in the process of video editing, if the user adds the silhouette of the new material video to the ongoing video editing, the processor 10 will store the backup video of the new material video corresponding to the new silhouette according to the method. In order to make the backup video always correspond one-to-one with the silhouette being edited, extra backup video will not be stored and the storage space will not be wasted.

Please refer to Figure 7. In the example shown in Figure 7, Figure 7a is an interface for editing silhouettes of three material videos. After the user removes one silhouette, the number of silhouettes being edited is two as shown in Figure 7b. , at this time, as shown in FIG. 7c , one of the backup videos V12 in the second path 22 will be deleted, and the backup video V12 is obtained by copying the material video corresponding to the removed silhouette.

Referring to FIG. 8 , in some embodiments, the video processing method further includes step 06, and step 06 is to delete the backup video when the video file is closed.

Please refer to FIG. 2 , in some embodiments, the processor 10 can be used to implement step 06, that is, the processor 10 can be used to delete the backup video when the video file is closed.

Wherein, closing the video file includes completing the processing of the video file, or terminating the processing of the video file.

Specifically, taking opening a video file through the video processing interface as an example, the completion of processing the video file means that when the user confirms that the editing is completed, the processor 10 automatically processes the video file (material video or backup video) according to the editing operation, and automatically saves the processed video file as a separate file. Video files are placed in a file directory; termination of processing video files means that the user abandons video editing, and the instruction to abandon video editing may be that the user clicks the return button in the video editing interface, indicating that the user abandons this editing. Since the backup video is to ensure the normal progress of video editing, after the video editing is completed, when there is no need for video editing temporarily, the processor 10 can automatically call a process of cleaning the backup video to delete the backup video to avoid the increase of the backup video. The cache of the video editing APP prevents backup videos from occupying the storage space of the terminal 100 .

Referring to FIG. 9 , in the editing interface shown in FIG. 9 a , when the user clicks Finish, as shown in FIG. 9 b , the processor 10 deletes the backup video V12 in the second path 22 at the same time.

Further, in the process of processing the video file, if the material video is deleted from the first path, it is determined that the user may have deleted the material video by mistake. Therefore, before deleting the backup video, the processor 10 may issue an instruction to control the terminal 100 A prompt message is sent to prompt the user whether the material video needs to be restored. For example, a prompt window is displayed on the display screen of the terminal 100. When the user selects the need to restore, the stored backup video is backed up to the first path. In this way, it is equivalent to restoring the material video to the original first path, so as to recover the loss caused by the user accidentally deleting the material video.

Referring to FIG. 10 , in some embodiments, when the material video cannot be read through the first path, the video processing method further includes steps 07 and 08 . Step 07 is to generate a secondary backup video of the backup video and write the third path for storing the secondary backup video into the video file. Step 08 is to read the secondary backup video through the third path to replace the backup video when the video file is processed and the backup video cannot be read through the second path.

Please refer to FIG. 2 , in some embodiments, the processor 10 may be used to implement steps 07 and 08 . That is, the processor 10 can be used to generate the secondary backup video of the backup video and write the third path for storing the secondary backup video into the video file, and when processing the video file and the backup video cannot be read through the second path, The secondary backup video is read through the third path to replace the backup video.

As mentioned above, when opening a video file, such as in the process of editing the silhouette of the material video, after the material video is deleted, the backup video replaces the material video. However, if the subsequent editing process, the backup video is also deleted. , the editing can no longer be performed normally. Therefore, after the material video is deleted, the processor 10 will generate a backup of the backup video, that is, the secondary backup video. Even if the backup video is deleted, the backup video can be replaced with the secondary backup video to accept the final processing corresponding to the editing operation. Video editing can still be done as normal. After closing the video file later, you can delete the secondary backup video to save storage space.

Further, if the secondary backup video is required to replace the backup video, then the backup video of the secondary backup video can be generated at the same time, that is, the tertiary backup video. When the secondary backup video is deleted when processing the video file, the tertiary backup can be used. Video replacement The secondary backup video accepts the final processing corresponding to the editing operation. After closing the video file subsequently, the tertiary backup video can be deleted to save storage space.

Referring to FIG. 12 , the present application further provides a non-volatile computer-readable storage medium 200 containing computer-readable instructions. When the computer-readable instructions are executed by the processor 300, the processor 300 is caused to perform the video processing method of any one of the above embodiments.

Please refer to FIG. 1 and FIG. 11 , for example, when the computer-readable instructions are executed by the processor 300, the processor 300 is caused to perform step 01: process the material video to generate a video file; step 02: generate the material video when processing the video file backing up the video; and step 03: when the video file is processed and the material video cannot be read through the first path, the backup video is read through the second path to replace the material video.

Please refer to FIG. 5 and FIG. 11 , for example, when the computer-readable instructions are executed by the processor 300, the processor 300 executes step 04: after the material video cannot be read through the first path, cancel the connection between the silhouette and the first path. association.

6 and 11, for example, when the computer readable instructions are executed by the processor 300, the processor 300 executes step 05: in response to user input to delete the silhouette, disassociate the silhouette with the first path, and delete the backup video.

Please refer to FIG. 8 and FIG. 11 , for example, when the computer-readable instruction is executed by the processor 300, the processor 300 executes step 06: when the video file is closed, delete the backup video.

Please refer to FIG. 10 and FIG. 11, for example, when the computer-readable instructions are executed by the processor 300, the processor 300 is caused to perform step 07: generate a secondary backup video of the backup video and write the third path for storing the secondary backup video and step 08: when the video file is processed and the backup video cannot be read through the second path, the secondary backup video is read through the third path to replace the backup video.
