[0058] FIG. 1 is a schematic flow chart of a video editing method according to an embodiment of the present disclosure. The embodiment of the present disclosure is applied to a case where editing subtasks are assigned to a video for editing. The method may be executed by a video editing device. The video editing device may be realized in the form of software and / or hardware, or may be disposed in any electronic device having a network communication function. The electronic device may be a mobile terminal, a PC terminal, a server, etc. As shown in FIG. 1, the video editing method of the present embodiment may include, but is not limited to, the following processes:

[0059] At S110, at least one editing subtask is created for the video editing task.

[0060] Referring to Fig. 2, one complete video may be decomposed into at least two video synopses according to video content, for example, video synopsis 1, video synopsis 2 and video synopsis 3 shown in Fig. 2. In this way, each video of different cases can be decomposed into different video synopses according to video content. For each video synopsis, a video editing subtask may be corresponding based on the creation format of the video synopsis. In this way, one video editing task may include at least one editing subtask.

[0061] Referring to FIG. 3, when entering an editing screen for performing a video editing task, the editing screen may create and display at least two video editing components 110 corresponding to the video synopsis. Each video editing component 110 corresponds to one editing subtask, and the same video synopsis includes at least one video editing component 110. A video editing component may be the smallest unit in a video editing process. For example, the editing screen of a video editing task may be a mainframe page shown in the left diagram in FIG. 3, and the editing screen of an editing subtask may be a preview editing page shown in the right diagram in FIG. 3. Due to the limited display dimension of the editing screen of a video editing task, some of the video editing components 110 may not be displayed in their entirety, and the video editing components 110 hidden in the editing screen of a video editing task may be displayed by sliding the video editing components.

[0062] 2 and 3, in the editing screen of the video editing task, at least one video editing component may be set corresponding to the same video synopsis, and the video editing component may be an editing subtask. For example, take a case where one video synopsis information is video synopsis M / N as an example, the video synopsis M / N may indicate that the video editing component selected by the dotted line is the video editing component corresponding to the Nth editing subtask of the Mth video synopsis. The types of the video editing components set corresponding to the same video synopsis may be the same or different. The same video editing components belong to the same video synopsis, that is, the same editing subtask cannot belong to different video synopses at the same time.

[0063] The above method can clearly present different editing methods in video editing by intuitively expressing the framework of the video content to be edited / generated by each created editing subtask, so that corresponding video editing components can be created according to the video editing subtasks as needed, simplifying the complexity of video editing and making the video editing process more intuitive and clear.

[0064] As an optional and non-limiting implementation method, refer to FIG. 4, and enlarge the video editing component corresponding to the editing subtask displayed on the editing screen of the video editing task shown in FIG. 3, and first annotation content and second annotation content are displayed on the video editing component, the first annotation content describes the editing type of the editing subtask corresponding to the video editing component, the second annotation content describes the time of the video clip generated by the editing subtask corresponding to the video editing component, and the cover of the video editing component is the first frame of the video clip generated by the editing subtask corresponding to the video editing component.

[0065] The editing types of the editing subtasks corresponding to the video editing component may include narration video editing, selfie video editing, and chromakey shot video editing. Narration video is where the main narration content is from a monologue, which is recorded independently and is generally a spoken or converted audio from text, and the video screen can jump based on the audio content. Selfie video is a video clip where a person stands in front of the camera and gives a narration. Chromakey shot video includes a video clip where a person stands in front of the camera and gives a narration, combined with a picture or recording of a product in the background.

[0066] Using the above method, the duration and video editing mode of each video clip of each editing subtask can be clearly defined during the execution of the video editing subtask, so that the video clips can be reduced and added for each editing subtask according to actual needs, and the video editing mode can be optimized and adjusted to generate a better video.

[0067] At S120, in response to a first operation for triggering the target editing subtask, a source video material is obtained and an editing screen of the target editing subtask is displayed, where an editing track is displayed on the editing screen of the target editing subtask, a video track clip formed based on the source video material is placed on a video track in the editing track, and at least one editing subtask includes the target video editing subtask.

[0068] 3, a video editing component corresponding to at least one editing subtask displayed on an editing screen of a video editing task can trigger a target editing subtask of the at least one editing subtask in response to a first operation on the video editing component, and after triggering the target editing subtask, obtain an original video material and jump to the editing screen of the target editing subtask to display the editing screen. The editing screen is for video editing the editing subtask corresponding to the video editing component. An editing track is displayed on the editing screen, and a video track clip formed based on the original video material is placed on the video track in the editing track.

[0069] In S130, in editing the target editing subtask, an editing operation triggered on the editing screen is recorded and an instruction mark for the editing operation is displayed on the editing track.

[0070] Referring to FIG. 3, in one example, in an edit track displayed on an edit screen, a video split edit operation can be triggered for a video track clip of the edit track. Thereby, edit operation information for splitting a video track clip to be performed in the video track can be recorded, and an indicator mark for indicating that the video track clip has been video split in the video track can be displayed. In another example, a video speed change edit operation can be triggered for a video track clip of the edit track. Thereby, edit operation information for performing a video speed change in the video track clip can be recorded, and an indicator mark for indicating that the video track clip has been video speed changed in the video track can be displayed. In a further example, a video special effect edit operation can be triggered for a video track clip of the edit track. Thereby, edit operation information for performing a video special effect in the video track clip can be recorded, and an indicator mark for indicating that a video special effect operation has been performed on the video track clip in the video track can be displayed.

[0071] At S140, in response to a second operation for confirming completion of the target editing subtask, an editing result of the target editing subtask is generated based on the recorded information of the editing operation and the original video material.

[0072] Referring to Fig. 3, after video editing the editing screens corresponding to each editing subtask created on the editing screen of the video editing task, a second operation can be triggered on the editing screen to confirm the completion of the target editing subtask, at which time, an editing result of each editing subtask can be generated according to the recorded result of the editing operation recorded on the editing screen of the corresponding editing subtask and the original video material.

[0073] Using the above method, different types of video content clips are divided in the overall video in the manner of different editing sub-tasks, and video clips are formed by inputting video material according to the video editing components corresponding to the different editing sub-tasks, thereby providing step-by-step guidance to complete video editing on editing screens corresponding to the video editing components of the different editing sub-tasks.

[0074] In S150, based on the editing results of each editing subtask of the video editing task, a target video is generated as an editing result of the video editing task, and in the target video, the original video material is displayed according to an editing effect corresponding to the editing operation.

[0075] After the editing subtasks corresponding to each video editing component edit the video to obtain the editing results of each editing subtask, the editing results of the editing subtasks corresponding to each video editing component can be directly merged and concatenated, so that the editing result of the complete video editing task is generated as the target video, and the editing subtasks corresponding to different video editing components are guided to edit the video, thereby completing the video editing step by step to generate a final complete video.

[0076] As an optional and non-limiting implementation method, referring to FIG. 3, generating a target video as an editing result of a video editing task based on the editing results of each editing subtask of the video editing task may include, but is not limited to, the following steps A1 to A2.

[0077] In step A1, an original audio material is acquired, and an editing screen of the video editing task displays an audio track clip formed based on the original audio material and a video track clip formed based on the editing results of each editing subtask of the video editing task.

[0078] In step A2, in response to an editing operation on an audio track clip, a target audio material is obtained, and a target video is generated based on the editing results of each editing subtask of the video editing task and the target audio material.

[0079] Referring to the left diagram of FIG. 3, a music icon 130 is displayed on the editing screen of the video editing task. If the music is empty, clicking the music icon will pull up the music selection page to select the appropriate music. Only one music can be added to the entire video. After completing the addition, return to the editing screen of the video editing task and enter the music editing panel to edit the added music. When entering the editing template of the video editing task for the first time, the music icon displayed on the editing screen of the video editing task is in the added state. Clicking it will display the music attached to the editing template, and entering the music editing panel will automatically align the music duration with the duration of the current video.

[0080] As an optional and non-limiting implementation method, the video editing method of this embodiment may further include obtaining and saving a target sub-video corresponding to the target editing sub-task based on the editing result of the target editing sub-task, and displaying the original video material in the target sub-video according to an editing effect corresponding to the editing operation.

[0081] The editing result based on the target editing subtask may be a video generated in response to the target editing subtask based on the recorded information of the editing operations and the original video material. When the editing result based on the target editing subtask is obtained, the video corresponding to each target editing subtask can be composited into the target video. The editing result based on the target editing subtask may be an editing draft generated based on the recorded information of the editing operations and the original video material. When the editing draft corresponding to the target editing subtask is obtained, the editing draft corresponding to each target editing subtask can be merged and then a total editing draft after merging can be generated for the target video.

[0082] In the technical solution of the embodiment of the present disclosure, at least one editing subtask is created in a video editing task, and in response to a first operation for triggering a target editing subtask, an original video material is obtained and an editing screen of the target editing subtask is displayed, and the framework of the video content to be edited / generated by each created editing subtask is intuitively expressed, and in the editing of the target editing subtask, an editing operation to be triggered on the editing screen is recorded and an instruction mark of the editing operation is displayed on the editing track, so that the editing / generation of the entire video is divided into different editing subtasks, and the different editing subtasks are guided to complete the video editing. Thus, the complexity of the video editing is simplified, and even if an editing error occurs in the editing, the editing subtask with the error can be re-edited, thereby improving the efficiency of the video editing / generation.

[0083] 5 is a schematic flow chart of another video editing method according to an embodiment of the present disclosure. The technical solution of this embodiment further optimizes the process of creating at least one editing subtask in the video editing task in the above embodiment based on the above embodiment. This embodiment can be combined with each optional technical solution in one or more embodiments. As shown in FIG. 5, the video editing method of this embodiment may include, but is not limited to, the following steps:

[0084] At S510, an editing template used for a video editing task is obtained.

[0085] In S520, an editing subtask specified in the editing template is determined.

[0086] At S530, at least one editing subtask is created for the video editing task based on the editing subtask specified in the editing template.

[0087] As an optional and non-limiting implementation manner, creating at least one editing sub-task for a video editing task based on an editing sub-task specified in an editing template may include, but is not limited to, the following steps B1-B2.

[0088] In step B1, the editing screen of the video editing task displays the symbols of the editing subtasks specified in the editing template.

[0089] With reference to FIG. 2 and FIG. 6, different editing templates may be set in advance. When performing a video editing task in response to a trigger operation of the template, an editing template used for the video editing task may be selected, and editing subtasks designated to be included therein may be analyzed from the editing template. With reference to FIG. 3 and FIG. 6, in response to a trigger for the editing template of the selected video editing task, each editing subtask for performing the video editing task is called, and a video editing component for performing each editing subtask of the video editing task designated in the editing template is displayed on the editing screen of the video editing task. Here, at least one editing subtask corresponds to the same video summary, each editing subtask corresponds to one video editing component, and the label of the editing subtask may be indicated by the video editing component displayed on the editing screen of the video editing task. For example, the video editing component A, the video editing component B, and the video editing component C shown in FIG. 6 are displayed in the label format of each editing subtask.

[0090] In step B2, in response to a third operation for triggering the addition of an editing subtask, a notation of the first editing subtask is added to the editing screen of the video editing task, and / or in response to a fourth operation for triggering the deletion of the editing subtask, a notation of the second editing subtask is removed from the editing screen of the video editing task.

[0091] At least one of the editing subtasks includes an editing subtask in which a mark is displayed on an editing screen of the video editing task.

[0092] In one selectable example, in response to a third operation for triggering the addition of an editing subtask, a label for each editing subtask being displayed on the editing screen of the video editing task (i.e., which may be a label for visually displaying a video editing component corresponding to the editing subtask) is selected, and a subtask operation menu for the label of the selected editing subtask is synchronously displayed, and a control for triggering editing (hereinafter, an "edit trigger control"), a control for triggering addition (hereinafter, an "add trigger control"), and a control for triggering deletion (hereinafter, a "delete trigger control") are displayed in the subtask operation menu.

[0093] With reference to FIG. 7, for the video editing components 110 corresponding to each editing subtask displayed on the editing screen of the video editing task, the video editing components on the editing screen may be visualized and displayed by marking the editing subtask in the figure. In response to a click operation on any one of the video editing components, i.e., in response to a click operation on the marking of one editing subtask, the clicked video editing component 110 may be box-selected on the editing screen of the video editing task. For example, the video editing component 110 of the first editing subtask of the M+1th video summary in FIG. 7 is selected. When the video editing component 110 is selected, the subtask operation menu of the corresponding editing subtask of the selected video editing component may be pulled up and displayed as a pop-up on the editing screen of the video editing task. An edit trigger control, an add trigger control, a delete trigger control, and the like displayed on the subtask operation menu may be clicked and triggered.

[0094] In one selectable example, referring to FIG. 7, in response to a fourth operation for triggering the deletion of the editing subtask, a mark of the second editing subtask being displayed on the editing screen of the video editing task (a mark for correspondingly visually displaying a video editing component corresponding to the editing subtask) is selected, and a subtask operation menu of the mark of the second editing subtask is synchronously displayed.
