[0029] The names of messages or information exchanged between multiple devices in the embodiments of this disclosure are for illustrative purposes only and are not intended to limit the scope of such messages or information.

[0030] To address the aforementioned issues, this disclosure provides a video editing method in which video editing templates can be reused, thereby improving video editing efficiency and flexibility.

[0031] The method will be described below with reference to specific embodiments.

[0032] Figure 1 This is a flowchart illustrating a video editing method provided in an embodiment of the present disclosure. The method can be executed by a video editing device, which can be implemented using software and / or hardware, and is generally integrated into an electronic device. Figure 1 As shown, the method includes:

[0033] Step 101: Obtain a video editing template; wherein the video editing template is generated based on first multimedia data; the first multimedia data includes at least one multimedia material and editing information, the editing information being used to indicate editing operations for at least one multimedia material; the video editing template includes tagging information, the tagging information being used to indicate that the first multimedia material in at least one multimedia material is marked as a replaceable material.

[0034] In one embodiment of this disclosure, a video editing template is obtained. This video editing template is generated based on first multimedia data, which includes at least one multimedia material such as images, text, and audio. The first multimedia data may also include editing information, which is used to indicate editing operations for at least one multimedia material. For example, each multimedia material includes multiple editing tracks, and each editing track includes one type of editable information from the corresponding multimedia material. For example, multimedia material A includes a text editing track, an audio editing track, an image editing track, etc. The editing operation in this embodiment can be an editing operation on the editable information of any track in the multimedia material. For example, the editing operation is image effects processing in the image editing track.

[0035] It is easy to understand that the video editing template itself is the first multimedia data in video form. To facilitate the processing of the corresponding first multimedia data into a video editing template, in one embodiment of this disclosure, marking information is used to indicate that at least one multimedia material is marked as a replaceable material. To facilitate the application of the video editing template, this marking information can be displayed visually on the corresponding multimedia material. The display style of the marking information can be set according to the needs of the scenario; for example, it can be as follows: Figure 2 As shown, the tag information can be a "replaceable" text style.

[0036] Step 102: Based on the video editing template, display the video editing interface; the video editing interface presents a timeline-based video editing track, on which a first video track segment is presented, and the first video track segment corresponds to a second video track segment formed by the first multimedia material in the first multimedia data.

[0037] In one embodiment of this disclosure, a video editing interface is displayed based on a video editing template, so that the video editing template can be reused on the video editing interface, wherein, as... Figure 3 As shown, the video editing interface displays a timeline-based video editing track. The video editing track displays a first video track segment, which corresponds to a second video track segment formed from the first multimedia material in the first multimedia data. The first video track segment can be the second video track segment, and the first video track segment can be a video track segment generated by freezing a target image frame, where the target image frame is an image frame in the first multimedia material.

[0038] In other words, the first video track segment displayed on the video editing interface can be either a second video track segment formed from the first multimedia material, or a single image frame from the first multimedia material. For example, ... Figure 4 As shown, when the first multimedia data contains a video segment containing image frames B1-B4, the first video track segment can be a second video track segment composed of B1-B4, or it can be a video track segment generated by freezing B1.

[0039] Step 103: In response to the material import operation for the first video track segment, the first video track segment is replaced with the third video track segment to obtain the second multimedia data; the third video track segment corresponds to the fourth video track segment formed by the second multimedia material indicated by the material import operation, and the first video track segment and the third video track segment occupy the same timeline position on the video editing track.

[0040] In this second multimedia data, compared to the first multimedia data, the first multimedia material in the first multimedia data is replaced with the second multimedia material in the second multimedia data.

[0041] In one embodiment of this disclosure, a material import operation can be performed directly on the first video track segment to replace the first video track with a third video track segment to obtain the second multimedia data, thereby enabling the reuse of relevant video editing templates.

[0042] The third video track segment corresponds to the fourth video track segment formed by the second multimedia material indicated by the material import operation. In one embodiment of this disclosure, after obtaining the second multimedia data, the second multimedia data can be exported to obtain a video export operation. This video export operation can be implemented by triggering a preset export control, or by executing other bound events corresponding to the export operation. For example, in some optional implementations, the export operation can be implemented by double-clicking the current video editing page.

[0043] In one embodiment of this disclosure, in response to a video export operation, it is detected whether a first video track segment has been replaced with a third video track segment. If the replacement is complete, a target video is directly generated based on the second multimedia data, and the user can further perform operations such as saving or sharing the target video. If the replacement is not complete, a replacement guidance prompt is given to the first video track segment, such as displaying text prompts to indicate whether the target video should be generated using the first video track segment since the current first track segment has not been completely replaced. In this embodiment, the replacement can be determined to be complete after all first video track segments have been completely replaced with third video track segments, or it can be determined to be complete after some first video track segments have been replaced with third video track segments. When some first video track segments have been replaced with third video track segments, the first video track segments that have not been replaced with third video track segments can be highlighted when the replacement guidance prompt is given, for example, by outlining the corresponding first video track segments that have not been replaced with third video track segments with a rectangle. In some possible embodiments, the target video segment can also reuse the first video track segment. For example, when a video export confirmation operation is obtained after receiving a replacement guidance prompt, all current video track segments are exported as the target video.

[0044] It should be emphasized that in this embodiment, the first video track segment and the third video track segment occupy the same timeline position on the video editing track, thereby realizing the operation of replacing the first video track segment with the third video track segment at the same timeline position.

[0045] In one embodiment of this disclosure, in order to ensure that the first video track segment and the corresponding third video track segment are aligned on the time axis, the first duration corresponding to the second multimedia material is compared with the second duration of the first video track segment. If the first duration is less than the second duration, the playback speed of the second multimedia material is slowed down so that the playback duration of the adjusted video segment is the second duration. For example, the playback duration of each frame of the second multimedia material is determined based on the duration difference between the second duration and the first duration, and the playback duration of the video segment corresponding to the second multimedia material is adjusted by playing the second multimedia material with this duration.

[0046] If the first duration is greater than the second duration, then the material is extracted starting from the first frame of the second multimedia material so that the playback duration of the video segment generated from the extracted second multimedia material is the second duration. That is, a video segment with the same playback duration as the second duration is extracted from the second multimedia material as the third video track segment. Of course, in some possible embodiments, the difference between the first duration and the second duration can also be calculated, and the playback duration of each image frame of the second multimedia material can be determined based on the difference. The playback duration of the video segment corresponding to the second multimedia material is adjusted by playing the second multimedia material with this duration, so that the playback duration of the adjusted second multimedia material is the same as the second duration, without the need to extract the second multimedia material.

[0047] In addition, in the embodiments of this disclosure, compared with the first multimedia data, the first multimedia material in the first multimedia data is replaced with the second multimedia material in the second multimedia data, wherein the editing operations of the first multimedia material are retained, thereby realizing the reuse of video editing templates.

[0048] Of course, in one embodiment of this disclosure, to further meet the needs of video editing, the second multimedia material can also be edited. That is, in one embodiment of this disclosure, after replacing the first video track segment with the third video track segment to obtain the second multimedia data, an editing area can be displayed in response to editing operations on the second multimedia material, such as in response to a preset trigger operation on the second multimedia material, or in response to a trigger operation on a preset editing control. The editing area contains various editing menus for the second multimedia material, including a color editing menu for the second multimedia material, etc. The second multimedia material can be edited in the editing area. Thus, without jumping to other video editing interfaces, the editing of the second multimedia data can be achieved on the video template editing interface of the current second multimedia data, further improving video editing efficiency.

[0049] For example, such as Figure 5As shown, after replacing the first video track segment with the third video track segment to obtain the second multimedia data, the corresponding editing area for the second multimedia material under the current timeline can be displayed. This editing area can include menus for adjusting the size, color, and brightness of the second multimedia material. Editing of the second multimedia material can be performed within this editing area.

[0050] Of course, in one embodiment of this disclosure, the editing operations in the first multimedia data can also be edited a second time so that the result of the second editing can be reused in the subsequent second multimedia data. For example, at least one replaceable text fragment in the first multimedia data can be displayed in the text area of ​​the video editing interface.

[0051] Furthermore, in response to the selection operation of the target text fragment in the text area, the target text fragment can be an editable text fragment in the multimedia material of the first multimedia data. At least one video frame is marked on the video editing track based on the timeline, wherein the video frame corresponds to the position of the target text fragment in the first multimedia data. The video frame corresponding to the timeline can be actively selected by the user, or the video frame content information of each video frame in the first multimedia data can be identified. It is determined whether it matches the target text fragment based on the video frame content information. The video frame corresponding to the target text fragment is determined based on the matching result. It is also possible to optionally set the correspondence between each replaceable text fragment and the corresponding video frame. After selecting the target text fragment, the preset correspondence is queried to determine the corresponding video frame. In response to the editing operation of the target text fragment, the edited text fragment is synchronously displayed in the video player, wherein the edited text fragment can be reflected in the second multimedia data.

[0052] For example, such as Figure 6 As shown, in the text area of ​​the video editing interface, the replaceable text fragments in the first multimedia data are "2222222", "333333", and "44444444". In response to the editing operation of the selected replaceable text fragment "2222222" in the text area, video frames (video frames in the rectangle in the figure) are marked on the video editing track based on the timeline. In response to the editing operation of the target text fragment, the edited text fragment corresponding to this editing operation is "wwwww", and the corresponding text fragment "wwwwww" is displayed synchronously in the player.

[0053] Of course, in actual execution, the video editing interface can also display other editing tracks for editing the first video track segment. These other editing tracks include tracks for trimming, speed adjustment, and other editing of the first video track segment. Alternatively, the video editing interface can also display other editing tracks for editing the third video track segment. Similarly, these other editing tracks can include tracks for trimming, speed adjustment, and other editing of the third video track segment. This satisfies other editing needs for video editing, allowing other editing operations to be performed directly on the video editing interface without having to switch to other pages, further improving the efficiency of video editing.

[0054] In summary, the video editing method of this disclosure obtains a video editing template. The video editing template is generated based on first multimedia data. The first multimedia data includes at least one multimedia material and editing information, the editing information indicating editing operations for the at least one multimedia material. The video editing template includes marking information indicating that the first multimedia material in the at least one multimedia material is marked as replaceable material. Based on the video editing template, a video editing interface is displayed. The video editing interface presents a timeline-based video editing track, on which a first video track segment is presented. The first video track segment corresponds to a second video track segment formed by the first multimedia material in the first multimedia data. In response to a material import operation for the first video track segment, the first video track segment is replaced with a third video track segment to obtain second multimedia data. The third video track segment corresponds to a fourth video track segment formed by the second multimedia material indicated by the material import operation. The first video track segment and the third video track segment occupy the same timeline position on the video editing track. Compared to the first multimedia data, the first multimedia material in the first multimedia data is replaced with the second multimedia material in the second multimedia data. Thus, video editing based on the video editing template is realized, improving the efficiency and flexibility of video editing.

[0055] As can be seen from the above embodiments, in the video editing method proposed in this disclosure, the first video track segment is replaced with the third video track segment to generate the second multimedia data. The first video track segment and the third video track segment occupy the same timeline position on the video editing track. The second multimedia data and the first multimedia data contain multiple video track segments on the same timeline. The editing operation of each video track segment can reuse the editing operation corresponding to the first multimedia material in the first multimedia data, thereby realizing the reuse of video editing templates.

[0056] The following describes, with reference to a specific embodiment, how to replace the first video track segment with the third video track segment.

[0057] In one embodiment of this disclosure, at least one multimedia material corresponding to the first multimedia data further includes a third multimedia material. That is, the first video track segment is a composite video segment, corresponding to a combination of the second and fifth video track segments. The fifth video track segment is a video track segment formed from the third multimedia material within the first multimedia data. The second and fifth video track segments overlap on the timeline. The composite video segment can be displayed visually on the video editing track, for example, displaying that the corresponding first video track segment contains "3 video segments, etc." When the composite video segment is selected, multiple corresponding video segments are displayed in a list or other format, allowing the user to replace the video segments. For example, ... Figure 7A As shown, when the first video track segment is a composite video segment, in addition to the second video track segment, it may also include at least one fifth video track segment composed of third multimedia material (two fifth video track segments are shown in the figure). There are overlapping parts between the multiple video segments on the timeline. This overlap can be any form of overlap. For example, the multiple video segments may have the same start time but not the same end time, or the multiple video segments may have different start and end times, etc.

[0058] In this embodiment, in response to a material import operation for a first video track segment, the first and second sub-segments of a second video track segment can be displayed in chronological order in response to a trigger operation for the first video track segment. Here, the first sub-segment can be understood as corresponding to the second video track segment, and the second sub-segment can be understood as corresponding to the fifth video track segment. Furthermore, in response to a first import operation for the first sub-segment, the first sub-segment is replaced with a third sub-segment, where the third sub-segment corresponds to the fourth video track segment. In this embodiment, in response to a material import operation for the second sub-segment, the second sub-segment is replaced with a fourth sub-segment, where the fourth sub-segment corresponds to the sixth video track segment formed by the fourth multimedia material. The material import operation includes a first import operation and a second import operation. The first import operation instructs the import of the second multimedia material into the first sub-segment, and the second import operation instructs the import of the fourth multimedia material into the second sub-segment.

[0059] For example, such as Figure 7BAs shown, when the first video track segment is a composite track segment, including a first sub-segment W1 and a second sub-segment W2, W1 and W2 are displayed in chronological order in response to a trigger operation on the first video track segment. In response to a material import operation on W1, and in response to a first import operation on the first sub-segment, the first sub-segment W1 is replaced with a third sub-segment W3, which corresponds to the fourth video track segment. In response to a material import operation on the second sub-segment W2, the second sub-segment is replaced with a fourth sub-segment W4, which corresponds to the sixth video track segment formed by the fourth multimedia material. Thus, the first video track segment is replaced with the third video track segment, which corresponds to a combined segment of the fourth and sixth video track segments. After the aforementioned material import operation, the first video track segment is replaced with the third video track segment, which corresponds to a combined segment of the fourth and sixth track segments. This achieves the replacement of multiple sub-segments ultimately corresponding to the composite video track segment.

[0060] In one embodiment of this disclosure, in response to a material import operation for a first video track segment, replacing the first video track segment with a third video track segment to obtain second multimedia data may include:

[0061] In response to the material import operation for the first video track segment, the material upload entry is displayed. The style of the material upload entry can be set according to the needs of the scene. In response to the upload operation for the second multimedia material selected by the material upload entry, the first video track segment is replaced with the third video track segment to obtain the second multimedia data.

[0062] That is, in this embodiment, such as Figure 8 As shown, an "Import" control from the local media library can be provided on the video editing interface as an entry point for uploading media. After the "Import" control is triggered, the corresponding candidate second multimedia media from the local media library is displayed. In response to the triggering operation of multiple candidate second multimedia media, the selected second multimedia media can be uploaded.

[0063] In one embodiment of this disclosure, in response to a material import operation for a first video track segment, replacing the first video track segment with a third video track segment to obtain second multimedia data may include: in response to an add operation for a selected second multimedia material on the material panel, replacing the first video track segment with a third video track segment to obtain second multimedia data. That is, in this embodiment, multiple candidate second multimedia materials are displayed on the material panel, and a selection operation can be performed on the candidate second multimedia materials to replace the first video track segment with the corresponding third video track segment to obtain second multimedia data.

[0064] In this embodiment, as Figure 9 As shown, an import control can be displayed on each second multimedia material, such as a "+" control. When the import control is triggered, a material display panel is displayed, showing multiple candidate second multimedia materials. A selection operation can be performed on the candidate second multimedia materials to replace the currently selected first video track segment with the corresponding third video track segment to obtain the second multimedia data.

[0065] In this embodiment, other operation methods can also be used to replace the second multimedia material. For example, in response to the drag operation of the second multimedia material selected on the material panel to the first video track segment, the first video track segment can be replaced with the third video track segment to obtain the second multimedia data.

[0066] In addition, in the embodiments of this disclosure, after replacing the first video track segment with the third video track segment, the replaced third video track segment can be replaced again, and if the client currently performing the editing is editing for the first time, editing prompts and guidance information can be displayed at each step.

[0067] In summary, the video editing method of this disclosure can replace the first video track segment with the third video track segment in different ways according to different application scenarios, thereby further improving the flexibility of video editing.

[0068] To implement the above embodiments, this disclosure also proposes a video editing apparatus. Figure 10 This is a schematic diagram of a video editing device provided in an embodiment of the present disclosure. The device can be implemented by software and / or hardware and is generally integrated into an electronic device for video editing. Figure 10As shown, the video editing device includes: an acquisition module 1010, a display module 1020, and a replacement module 1030. The acquisition module 1010 is used to acquire a video editing template. The video editing template is generated based on first multimedia data. The first multimedia data includes at least one multimedia material and editing information, the editing information indicating editing operations for at least one multimedia material. The video editing template includes marking information indicating that the first multimedia material in the at least one multimedia material is marked as a replaceable material.

[0069] The display module 1020 is used to display a video editing interface based on a video editing template. The video editing interface presents a timeline-based video editing track, on which a first video track segment is presented. The first video track segment corresponds to a second video track segment formed by the first multimedia material in the first multimedia data.

[0070] Replacement module 1030 is used to replace the first video track segment with a third video track segment in response to a material import operation for the first video track segment to obtain second multimedia data; the third video track segment corresponds to a fourth video track segment formed by the second multimedia material indicated by the material import operation, and the first video track segment and the third video track segment occupy the same timeline position on the video editing track;

[0071] In this second multimedia data, compared to the first multimedia data, the first multimedia material in the first multimedia data is replaced with the second multimedia material in the second multimedia data.
