Obviously, the described embodiments are only some of the embodiments of the present disclosure, rather than all the embodiments.

[0029] It should be noted that the user information (including but not limited to user device information, user personal information, etc.) and data (including but not limited to data for analysis, stored data, displayed data, etc.) involved in the present disclosure are all information and data authorized by the user or authorized by all parties, and the collection, use and processing of related data need to comply with relevant laws, regulations and standards of countries and regions, and provide corresponding operation portal for user to choose authorization or refusal.

[0030] The application scenarios of the embodiments of the present disclosure are explained as follows:

[0031] The video draft generation method provided by the embodiments of the present disclosure can be applied in an application program (APP, Application) with video editing function, such as a video editing application program, a short video application program, etc. More specifically, it can be applied in the application scenario of video editing. The execution subject of the present embodiment can be a terminal device running the above-mentioned application program with video editing function, or a server deploying the server of the above-mentioned application program, or other electronic devices with similar functions. When the execution subject is a terminal device, the terminal device executes the method provided by the present embodiment by running the above-mentioned application program; when the execution subject is a server, the server of the above-mentioned application program with video editing function can be partially or entirely run on the server, and the method provided by the present embodiment is executed on the server side, while the terminal device runs the client of the application program, or runs a browser. The server and the terminal device communicate based on the client-server (CS) architecture, or the server and the terminal device communicate based on the browser-server (BS) architecture, so that the terminal device can obtain the execution result of the method provided by the present embodiment and display it as needed.

[0032] In some embodiments, the terminal device or server can implement the video draft generation method provided in this disclosure by running various computer-executable instructions or computer programs. For example, computer-executable instructions can be program-level commands, machine instructions, or software instructions. Computer programs can be native programs or software modules in an operating system; they can be local applications, i.e., programs that need to be installed in the operating system to run, or mini-programs embedded in any APP, i.e., programs that run in a browser environment. In summary, the aforementioned computer-executable instructions can be any form of instruction, and the aforementioned computer programs can be any form of application, module, or plugin; the specific implementation can be configured as needed. Furthermore, in implementing the video draft generation method provided in this disclosure, the terminal device can execute the method by running computer-executable instructions or computer programs set locally, or by calling computer-executable instructions or computer programs set in an external server. In some embodiments, the server may be an independent physical server, a server cluster or distributed system composed of multiple physical servers, or a cloud server that provides basic cloud computing services such as cloud services, cloud storage, cloud communication, cloud database, cloud computing, cloud functions, network services, middleware services, domain name services, security services, content delivery network (CDN), and big data and artificial intelligence platforms. Among these, cloud services may be interactive processing services that can be invoked by terminal devices.

[0033] Figure 1 This is an application scenario diagram of the video draft generation method provided in this disclosure embodiment, with reference to... Figure 1 As shown in the diagram, taking a terminal device as an example, the terminal device runs a target application with video editing functions. The user launches this target application to display a video editing interface. Within the video editing interface, there is a media library, a media track, and a playback window for previewing video drafts. The user selects media materials such as videos (video clip #1, video clip #2), images (image #3), and music (music clip #4) from the media library and loads them onto the media track to generate a video draft. Then, the user plays the video draft through the playback window to demonstrate the video editing effect. The user can further adjust the overlay and playback order of the various media materials as needed to obtain a video editing solution that meets their requirements. Finally, by exporting the video draft, the user obtains the final video editing result, which is a video clip composed of the aforementioned media materials.

[0034] In the prior art, only one timeline is usually included in a video editing interface, and since the content video draft needs to be based on all media materials in the material track on the timeline, the alternatives cannot be kept on the timeline, which makes the user unable to efficiently and intuitively compare between multiple video editing schemes, and unable to quickly replace the video editing scheme, thereby affecting the video editing efficiency.

[0035] Embodiments of the present disclosure provide a video draft generation method to solve the above problems.

[0036] Reference Figure 2 , Figure 2 Flowchart of the video draft generation method provided by the embodiments of the present disclosure Figure 1 The method of the present embodiment can be applied in a terminal device or a server. In the case of applying the method provided by the present embodiment to a terminal device, in one possible implementation, the terminal device can implement the video draft generation method provided by the present embodiment by executing program code deployed locally. In another possible implementation, the server can be used to deploy a function service based on the video draft generation method provided by the present embodiment, and the terminal device can implement the video draft generation method provided by the present embodiment by accessing the server and calling the corresponding function service. For example, the video draft generation method provided by the present embodiment includes:

[0037] Step S101: display a video editing interface, and at least two timeline components are set in the video editing interface, wherein a material track is configured in the timeline component, and the timeline component is used to generate a corresponding video draft based on an independent timeline.

[0038] Step S102: in response to a first operation on a first timeline component of the video editing interface, configure the content on the material track of the first timeline component, generate a first video draft based on the first timeline; or add the content on the material track of the first timeline component to the material track of a second timeline component of the video editing interface, and generate a second video draft based on the second timeline.

[0039] Reference Figure 1The application scenario diagram shown in the embodiment introduces the video draft generation method provided by taking a terminal device as an execution subject. For example, a target application program is a video editing application program. The terminal device displays a video editing interface by running the target application program. The video editing interface can be a main interface of the target application program or a secondary interface jumped from another function interface in the target application program, which is not limited here. In the video editing interface, at least two timeline components are arranged. The timeline component is a function component with an independent time axis. The timeline component is configured with a material track. The material track is used to load media materials. Each timeline component can generate a corresponding video draft based on the independent time axis by using the media materials loaded on the material track. Figure 3 A schematic diagram of a timeline component provided by an embodiment of the present disclosure is shown in FIG. 2. Figure 3 As shown in the figure, in the video editing interface, a material library component, a playing component, and at least two timeline components are arranged, for example, a first timeline component (shown as T1 in the figure) and a second timeline component (shown as T2 in the figure) shown in the figure. The user can select video, picture, music, and other media materials from the material library component and load them on the material track of any timeline component to generate a video draft corresponding to the timeline, for example, by responding to a first operation on the first timeline component of the video editing interface, loading video clip V1, video clip V2, and music clip M1 on the material track of the first timeline component to generate a video draft with a duration of n seconds (i.e., a first video draft based on the first timeline), and playing in the playing component. In another possible case, by responding to a first operation on the second timeline component of the video editing interface, loading video clip V3, video clip V1, and music clip M2 on the material track of the second timeline component to generate a video draft with a duration of m seconds (i.e., a second video draft based on the second timeline), and playing in the playing component. Through the above embodiment scheme, the media materials can be saved as different combinations of media materials, thereby realizing the effects of scheme backup, scheme recording, and scheme reference of the video editing scheme.

[0040] Further, in another possible implementation, in response to a first operation on the first timeline component of the video editing interface, the content on the material track of the first timeline component can be added to the material track of the second timeline component of the video editing interface to generate a second video draft based on the second timeline. Figure 4 A process diagram for generating a second video draft provided by an embodiment of the present disclosure is shown in FIG. 4. Figure 4As shown, after a first video draft based on a first timeline is generated by loading video clip V1, video clip V2 and music clip M1 onto the material track of the first timeline component (shown as T1 in the figure), the user adds video clip V1 and video clip V2 on the material track of the first timeline component to the material track of a second timeline component (shown as T2 in the figure) by applying a first operation, for example, in a dragging manner. In this case, video clip V1 and video clip V2 on the material track of the first timeline component remain on the material track of the first timeline component; and video clip V1 and video clip V2 are added to the material track of the second timeline component. Thus, the effect of quickly adding video clip V1 and video clip V2 to the material track of the second timeline component is achieved.

[0041] Further, in a possible implementation, among the at least two timeline components, there is one timeline component in an unfolded state and at least one timeline component in a folded state; a component panel of the timeline component in the unfolded state is displayed in a first area of the video editing interface, and a component label of the timeline component in the folded state is displayed in a second area of the video editing interface, where the component panel is used to display the material track configured in the timeline component. Figure 5 A state diagram of a timeline component provided by an embodiment of the present disclosure is shown in Figure 5 As shown, by way of example, after entering the video editing interface, a component panel of a first timeline component in an unfolded state is displayed by default in a first area of the video editing interface, and the component panel displays the material track configured in the timeline component, for example, the material track Track_1 and the material track Track_2 shown in the figure. A second timeline component in a folded state only displays a component label thereof, namely Timeline_2, in a second area of the video editing interface. When the component label is clicked, the second timeline component is set to an unfolded state, and the content on the material track of the second timeline component is displayed; meanwhile, the first timeline component is set to a folded state (this case is not shown in the figure). Optionally, the component label of the second timeline component, namely Timeline_1, can also be displayed in the second area. In this embodiment, different timeline components, for example, the first timeline component and the second timeline component, are displayed in a card form in a folded state, and the user can set them to an unfolded or folded state as needed, thereby increasing the operation area of the component panel of the timeline component in the unfolded state and improving the operation convenience.

[0042] In another possible implementation, the second timeline component can be configured to the display state in response to a second operation on the component label of the second timeline component, for example, clicking the component label Timeline_2 of the second timeline component, and then the component panel of the first timeline component and the component panel of the second timeline component are simultaneously displayed in the form of a split column in the first area of the video clip interface. Then, the user can transfer / add the media on the media track of any one of the timeline components to the media track of the other timeline component by operating the component panel of the first timeline component or the component panel of the second timeline component, to achieve flexible multi-timeline video clip scheme management and backup.

[0043] Further, the video clip interface is further configured with a playing component for displaying a video draft. After the first video draft based on the first timeline component is generated by performing the above steps, on one hand, the terminal device can perform image rendering based on the first video draft to play a corresponding preview video, that is, to play the first video draft. Meanwhile, the playing component can preload the second video draft corresponding to the second timeline component, and immediately play the second video draft through the playing component when the second timeline component is activated, to realize real-time switching display of the first video draft and the second video draft, facilitate the user to perform effect comparison, and improve the efficiency of video clipping.

[0044] In this embodiment, the video clip interface is displayed, and the video clip interface is provided with at least two timeline components. The timeline component is configured with a media track, and the timeline component is used to generate a corresponding video draft based on an independent time axis. In response to a first operation on a first timeline component of the video clip interface, the content on the media track of the first timeline component is configured to generate a first video draft based on the first timeline. Alternatively, the content on the media track of the first timeline component is added to the media track of a second timeline component of the video clip interface to generate a second video draft based on the second timeline. By providing at least two timeline components in the video clip interface, the user can configure media to the media track of any one of the timeline components, and the media configured in one timeline component can be added to the media track of another timeline component, to realize backup and rapid adjustment of the video clip scheme and improve the efficiency of video clipping.

[0045] Reference Figure 6 , Figure 6 Flowchart of a video draft generation method provided by the embodiment of the disclosure Figure 2 This embodiment is based on the embodiment shown in Figure 2 The video draft generation method provided by the embodiment of the disclosure includes:

[0046] Step S201: display a video clip interface, the video clip interface is provided with at least two timeline components and a material library component, wherein the timeline component is configured with a material track, and the timeline component is used to generate a corresponding video draft based on an independent time axis.

[0047] Step S202: in response to a first sub-operation on the material library component, select a target media material, and configure the target media material to the material track of the first timeline component to generate a first video draft based on the first timeline.

[0048] Step S203: in response to a second sub-operation on the target material identifier on the material track of the first timeline component, locate the target media material indicated by the target material identifier in the material library component.

[0049] Step S204: configure the target media material to the material track of the second timeline component to generate a second video draft based on the second timeline.

[0050] Exemplarily, in the process of selecting a media material from the material library and adding it to the timeline component, first, the terminal device selects a target media material in response to a first sub-operation on the material library component, wherein the first sub-operation is, for example, a point selection operation, and then the terminal device automatically, or in response to another user operation, configures the target media material to the material track of the first timeline component, the material track of the first timeline component displays a material identifier corresponding to the target media material, i.e., a target material identifier, which includes, for example, an indication icon, such as a frame arrangement icon corresponding to a video clip, or a text description, without limitation. Then, when it is needed to add the media material on the material track of the first timeline component to the material track of the second timeline component, in response to a second sub-operation, such as a point selection or drag operation, on the target material identifier on the material track of the first timeline component, the target media material is configured to the material track of the second timeline component, for example, the target material identifier corresponding to the target media material is added to the material track of the first timeline component to show the user the result of loading the target media material to the material track.

[0051] Further, in a possible implementation, the material library component includes a media library or a sub-draft library, wherein the media library is used to provide single media materials, and the sub-draft library is used to provide composite media materials, wherein the composite media materials are obtained by track-dimensionally superimposing at least one media sequence, and the media sequence includes a plurality of ordered arranged single media materials.

[0052] For example, a single media asset is a media asset consisting of a single asset file, such as a video clip, an image, a piece of music, and a special effect. Single media assets are stored in a media library, which will not be elaborated further here. A composite media asset, on the other hand, is formed by superimposing at least one media sequence along a track dimension. A media sequence includes multiple ordered single media assets, such as an arrangement of multiple video clips. Superimposing one or more media sequences located on different tracks constitutes a composite media asset. A composite media asset can be represented as a complete video draft, and a corresponding video clip can be directly generated using this composite media asset. Furthermore, this composite media asset is stored in a sub-draft library and saved as a sub-draft. Therefore, the process of generating composite media assets is similar to the process of generating a video draft, and can also be generated using the video draft generation method provided in this embodiment.

[0053] Figure 7 This is a schematic diagram illustrating the generation process of composite media material provided in an embodiment of this disclosure, such as... Figure 7 As shown, in the video editing interface, users can configure the media tracks within a timeline component. After loading media materials (such as image A, video B, and audio C as shown in the figure), the content on the media tracks of that timeline component can be stored as a composite media material M1. Image A and video B are located on the same track, forming a media sequence L1, while audio C is located on another track, forming another media sequence L2. This is then stored in the sub-draft library. Afterward, users can directly load this composite media material M1 onto the media tracks of a new project's timeline component. For example, as shown in the figure, by manipulating the sub-draft library, the composite media material M1 is loaded onto the media track of the first timeline component (shown as T1 in the figure), enabling rapid reuse of sub-drafts.

[0054] In one possible implementation, the target material identifier is used to indicate the target composite media material. In this case, after step S204, the following is also included:

[0055] Step S205: In response to the third operation of the target composite media material configured on the media track of the first timeline component, generate the modified target composite media material and synchronize the modified target composite media material to the media track of the second timeline component.

[0056] Step S206: In response to the third operation of the target composite media material configured on the media track of the second timeline component, generate the modified target composite media material and synchronize the modified target composite media material to the media track of the first timeline component.

[0057] Exemplarily, in the case that the target material is used to indicate the target composite media material, that is, the same composite media material is configured on the material tracks of the first timeline component and the second timeline component, in a possible implementation manner, in response to a third operation on the target composite media material configured on the material track of the first timeline component, the target composite media material is modified, for example, the position, duration, etc. of the media material in the target composite media material is modified, to generate a modified target composite media material. The target composite media material in the sub-draft library to which the modification operation is directed is globally modified, and then the modified target composite media material is synchronized to the material track of the second timeline component, that is, the target composite media material on the material track of the second timeline component is also automatically modified. In another possible implementation manner, in response to a third operation on the target composite media material configured on the material track of the second timeline component, the target composite media material is modified, for example, the position, duration, etc. of the media material in the target composite media material is modified, to generate a modified target composite media material. The target composite media material in the sub-draft library to which the modification operation is directed is also globally modified, and then the modified target composite media material is synchronized to the material track of the first timeline component on the other side, that is, the target composite media material on the material track of the first timeline component is also automatically modified. Since the target composite media material is a structure stored in the sub-draft library and has the same or similar data structure as the video draft, modification of the composite media material on any timeline component can achieve modification of the data body, thereby achieving global synchronization and improving the modification efficiency of the video editing scheme with the reference relationship of the composite media material.

[0058] Optionally, after step S204, the embodiment further includes:

[0059] Step S207: in response to a fourth operation on the composite media material configured on the material track of the first timeline component, displaying a material structure of the composite media material in the second timeline component, the material structure being used to represent the position of the media material constituting the composite media material on each material track.

[0060] Step S208: in response to a modification operation on the material structure of the composite media material in the second timeline component, synchronously modifying the corresponding composite media material in the first timeline component.

[0061] Exemplarily, in a possible implementation manner, the second timeline component is a subordinate functional component of the first timeline component, and is used to display the material structure of the selected composite media material in the first timeline component. Figure 8 A schematic diagram of the second timeline component provided by the embodiment of the disclosure is as follows: Figure 8As shown, in the video clip interface, in the initial state, the first timeline component is in the display state, and the second timeline component is in the folded state. Then, the composite media material M1 is loaded on the material track of the first timeline component, and in response to a fourth operation, such as a click operation, on the composite media material M1, the second timeline component is set to the display state, and the specific content of the composite media material M1 is displayed in the component panel of the second timeline component, for example, as shown in the figure, the composite media material M1 includes three material tracks, track_1, track_2 and track_3, wherein the track_1 loads the media sequence L1 composed of three video clips; the track_2 loads the media sequence L2 composed of three transition effects; and the track_3 loads the media sequence L3 composed of an audio and another composite media material M2. Through the component panel of the second timeline component, the detailed content display of the composite media material M1 loaded on the material track of the first timeline component is realized. Further, on this basis, in response to a modification operation on the material structure of the composite media material in the second timeline component, the corresponding composite media material in the first timeline component can be modified synchronously. Specifically, by responding to the operation instruction of the second timeline component, the content of the composite media material M1 displayed by the second timeline component can be modified, such as adjusting the duration of the video clip in the above-mentioned media sequence L1, replacing the video clip, etc., so as to realize the rapid adjustment of the multi-level content in the first timeline component and improve the efficiency of video editing.

[0062] Further, on this basis, if the composite media material M1 displayed by the second timeline component further includes a further composite media material, such as the composite media material M2, by clicking the composite media material M2, the content of the composite media material M2 (such as including multiple media sequences and single media materials constituting each media sequence) can be further displayed in other timeline components (such as the third timeline component or the first timeline component), and so on, to perform multi-level display until a composite media material composed of single media materials is displayed. Thus, efficient multi-level content display and editing are realized, and the efficiency of material adjustment in the video clip process is improved.

[0063] Further, exemplarily, the first timeline component and the second timeline component have the same project attribute, and the method further comprises:

[0064] Step S209: after the first timeline component is started, based on the project attribute, the second timeline component is started, and / or in the video clip interface, the version information corresponding to the timeline component is displayed.

[0065] Exemplarily, the first timeline component is a timeline component displayed in the video clip interface by default after a clip project is created, i.e., a main timeline component. In a possible implementation, on one hand, video clipping can be performed only through the first timeline component, a video draft is generated, and the video draft is saved as a composite media material. On the other hand, based on the display of the first timeline component, the terminal device can create a new timeline component, i.e., a second timeline component, in the video clip interface in response to a creation instruction, so that more than two timeline components are set in the video clip interface. The second timeline component is created based on the same clip project as the first timeline component, and therefore has the same project attribute.

[0066] In another possible implementation, when the first timeline component is used to load the video draft, the project attribute corresponding to the video draft is obtained, and then the terminal device can load the second timeline component belonging to the same clip project as the video draft based on the project attribute, so as to obtain the alternatives and reference schemes recorded for the video draft before, thereby improving the efficiency of video modification and secondary creation.

[0067] Exemplarily, on the other hand, when a timeline component (the first timeline component, the second timeline component, or the like) is selected or activated in the video clip interface, version information corresponding to the timeline component is displayed in a property area in the video clip interface, for example, including modification time, version number, video resolution, video duration, version description (for example, this version is compact in rhythm and cheerful in music), and the like, so that the user can quickly confirm the characteristics of the video editing schemes backed up in different timeline components through the version information, achieve the purpose of quickly generating video drafts of different versions, and improve the version management efficiency of multi-version video clip schemes.

[0068] In this embodiment, the implementation manner of step S201 is the same as that of step S101 in the embodiment of the disclosure Figure 2 The implementation manner of step S201 in this embodiment is the same as that of step S101 in the embodiment of the disclosure
