[0026] Before introducing specific embodiments of the present invention, let's first describe the application scenarios of the present invention as follows. The present invention can be applied to video editing processes, particularly when editing videos using video templates. Currently, in the process of editing using video templates, it is usually only possible to preview the effect video corresponding to one video template at a time. However, the visual differences between different video templates are not always large, and there may only be a few frames with clearly distinguishable features. When selecting a template, the user usually has to preview each video template one by one, which is time-consuming. Furthermore, the user can only preview one video template at a time, and there is a certain loading time required after selecting a video template. As a result, the user tends to forget the video effect they previewed earlier. When there are many video templates, it inevitably takes a very long time for the user to select their preferred video template, which does not help to improve the efficiency of video compositing or the user experience.

[0027] To solve the above technical problems, the present invention provides a video preview method, apparatus, readable medium, and electronic device, wherein the video preview method generates and displays a first target interface in response to receiving a video editing command for a video to be edited, the first target interface includes a template display area and a preview area, the template display area includes control buttons for a plurality of video templates, the preview area includes a first preview video corresponding to the first target video template among the plurality of video templates, and in response to obtaining a user trigger operation on a control button corresponding to the second target video template among the plurality of video templates, a second preview video corresponding to the second target video template is generated, and the first and second preview videos are displayed in the preview area, thereby facilitating the user to compare the effects of generating videos using different video templates, thereby improving the speed at which the user selects a video template, improving the efficiency of video compositing, and further effectively improving the user experience.

[0028] The technical solutions of the present invention will be described in detail below, along with specific examples.

[0029] Figure 1 is a flowchart of a video preview method shown in an exemplary embodiment of the present invention, which may include the following steps, as shown in Figure 1.

[0030] In step 101, in response to receiving a video editing command for the video to be edited, the first target interface is generated and displayed.

[0031] Here, the first target interface includes a template display area and a preview area, the template display area includes control buttons for multiple video templates, and the preview area includes a first preview video corresponding to the first target video template among the multiple video templates.

[0032] For example, the video to be edited may be a game video obtained by recording the screen, the video editing command may be triggered when the user clicks the stop recording button while recording the game screen, the video to be edited may be a video taken by the device's camera, or a video obtained by other means and stored locally on the device.

[0033] When generating and displaying the first preview video on the first target interface, a video template loading animation may be incorporated, and it should be explained that as the video template loading progress changes, a predetermined cartoon image peels off the mask layer on the video, causing the first preview video to light up and begin playing.

[0034] In step 102, in response to obtaining a user trigger operation on a control button corresponding to a second target video template among multiple video templates, a second preview video corresponding to that second target video template is generated.

[0035] Here, the second target video template is a video template other than the first video template among a group of video templates, and the trigger operation may be dragging (clicking, holding down, or double-clicking) the control button corresponding to the second target video template.

[0036] In step 103, the first preview video and the second preview video are displayed in the preview area.

[0037] In one steppable embodiment, the preview area includes a first display window and at least one second display window, the first display window being used to display a first preview video, and the second display window being used to display a second preview video, wherein in the step, the first display window may be reduced to a predetermined size, the reduced first display window may be moved to a first designated area within the preview area, the reduced first display window may be used to display the first preview video, and the second preview video may be displayed in the second display window within the second designated area.

[0038] Here, the sizes of the first and second display windows are the same, and the predetermined size can be obtained by acquiring the target number of preview videos currently displayed in the preview area and determining the predetermined size from a predetermined size correspondence relationship based on that target number.

[0039] The second target video template may include multiple templates. If there is only one second target video template, it should be noted that only one second preview video is included, and the first designated area may be on the left (or top) side of the preview area, and the second designated area may be on the right (or bottom) side of the preview area, as shown in Figure 2 (Figure 2 is a schematic diagram of a preview interface shown in an exemplary embodiment of the present invention). If there are two second target video templates, the first designated area may be in the left center (or top center) of the preview area, as shown in Figure 2 (b), and the second designated area may be on the upper right (or bottom left) side or the lower right (or bottom right) side. If there are three second target video templates, the first designated area may be in the upper left side of the preview area, as shown in Figure 2 (c), and the second designated area may be on the upper right, bottom right, or bottom left side.

[0040] Furthermore, if two (three, four, five, or six) preview videos are displayed in the preview area, the size corresponding to each display window may be pre-set; that is, a size correspondence relationship may be pre-generated, and this size correspondence relationship may be a correspondence between the target number recorded in the form of a list and a predetermined size. When a user selects a second target video template (i.e., a trigger operation is obtained for that second target video template), the target number of preview videos currently in the preview area is obtained, and a predetermined size can be determined based on this target number. For example, if three preview videos are currently displayed, including one first preview video and two second preview videos, the sizes corresponding to the three preview videos can be obtained from the size correspondence relationship, and the predetermined size can be obtained. In this way, the size of the display window corresponding to multiple preview videos can be flexibly controlled, and the number of preview videos displayed can be flexibly adjusted.

[0041] According to the above technical solution, by displaying the first and second preview videos in the preview area, it becomes easier for users to compare the effects of generating videos using different video templates. This improves the speed at which users can select video templates, enhances the efficiency of video compositing, and effectively improves the user experience.

[0042] Figure 3 is a flowchart of the video preview method shown in the embodiment of the present invention shown in Figure 1, and as shown in Figure 3, generating and displaying a first target interface in response to receiving a video editing command for the video to be edited as described in step 101 of Figure 1 may include the following steps.

[0043] In step 1011, in response to receiving the video editing command, a first target video template is determined from among multiple video templates.

[0044] In this step, the first playback duration of the video to be edited and the second playback duration of each video template are obtained, the target difference between the first playback duration of the video to be edited and the second playback duration of each video template is obtained, and the first target video template can be determined based on the designated video template having the smallest target difference.

[0045] Furthermore, in the process of determining the first target video template based on the designated video template with the smallest target difference, if it is determined that there are multiple designated video templates, the historical usage amount for each designated video template is obtained, and the designated video template with the largest historical usage amount is used as the first target video template.

[0046] For example, if the first playback duration of the video to be edited is 13 seconds, the second playback duration of video template A is 15 seconds, the second playback duration of video template B is 15.3 seconds, the second playback duration of video template C is 13.1 seconds, the second playback duration of video template D is 13.5 seconds, the second playback duration of video template E is 12.9 seconds, and the second playback duration of video template F is 12.6 seconds, then the target difference between the first playback duration and the second playback duration corresponding to each video template is obtained, and the target difference between the video to be edited and video template A is 2 seconds, the target difference between the video to be edited and video template B is 2.3 seconds, the target difference between the video to be edited and video template C is 0.1 seconds, the target difference between the video to be edited and video template D is 0.5 seconds, and the target video The target difference corresponding to the video template E is 0.1s, and the target difference corresponding to the video to be edited and the video template F is 0.5s. Since 0.1s is the smallest value among the multiple target differences, and the target differences corresponding to both the video template C and the video template E are both 0.1s, the first history usage corresponding to the video template C and the second history usage corresponding to the video template E can be obtained. If the first history usage is greater than the second history usage, the video template C is used as the first target video template. If the first history usage is less than the second history usage, the video template E is used as the first target video template. If the first history usage is equal to the second history usage, both the video template E and the video template C are used as the first target video templates.

[0047] In step 1012, the first preview video is generated based on the video to be edited and the first target video template.

[0048] In this step, when generating the first preview video, the first target video template can be loaded and then applied to the video to be edited to generate the first preview video.

[0049] When loading the first target video template, a video template loading animation may be combined, and relevant presentations of the template loading process may be displayed. It should be explained that as the video template loading progress changes, a predetermined cartoon image will peel off the mask layer on the video, and once it is determined that this will generate the first preview video, the first preview video will light up and begin playing.

[0050] In step 1013, the first preview video is displayed in the preview area.

[0051] In this step, the preview area may include a first display window, and the first preview video may be displayed using the first display window.

[0052] According to the above technical solution, the first target video template that is closest in duration to the video being edited is selected from multiple video templates, and when the user enters the first target interface, a first preview video corresponding to the first target video template can be displayed in the first target interface. This helps the user to quickly select a video template, effectively improves the efficiency of template selection, improves the efficiency of video compositing, and further effectively enhances the user experience.

[0053] Selectively generating and displaying a first target interface in response to receiving a video editing command for the video to be edited as described in step 101 of Figure 1 above may further include the following steps:

[0054] The control buttons for multiple video templates are displayed within the template display area in order of increasing target difference.

[0055] For illustrative purposes, taking the example again shown in step 1011 above, the arrangement order corresponding to the control buttons of the multiple video templates (i.e., video templates A to F) within the template display area is video template C, video template E, video template D, video template F, video template A, and video template B.

[0056] According to the above technical solution, control buttons for multiple video templates can be displayed within the template display area in order of increasing target difference, which helps users quickly select video templates, effectively improves template selection efficiency, enhances video compositing efficiency, and further effectively improves the user experience.

[0057] Selectively, the first target interface may further include a playback progress bar for the video to be edited, and the method may further include the following steps:

[0058] By establishing a relationship between the first preview video, the second preview video, and the playback progress bar, the playback progress bar is made to simultaneously control the playback progress of the first and second preview videos.

[0059] When multiple second preview videos are included, it is possible to control each preview video within the preview area using the playback progress bar of the video being edited by establishing a relationship between each second preview video and the playback progress bar of the video being edited. When each second preview video is added to the preview area, both the first and second preview videos will start playing from the beginning frame. This ensures that multiple preview videos play synchronously and that the screen displayed by all of the preview videos currently shown in the preview area is identical. In this way, it is necessary to explain that this helps users compare the display effects of the multiple preview videos and effectively improves the efficiency of selecting video templates.

[0060] According to the above technical solution, by establishing a relationship between the playback progress bars of the first preview video, the second preview video, and the video to be edited, it becomes possible to control the playback progress of the first and second preview videos using the playback progress bar of the video to be edited. This effectively improves video control efficiency and video template selection efficiency, contributing to an improved user experience.

[0061] Figure 4 is a flowchart of another video preview method shown in the embodiment of the present invention shown in Figure 1, and after displaying the first preview video and the second preview video in the preview area described in step 103 of Figure 1 above, as shown in Figure 4, the method may further include the following steps.

[0062] In step 104, in response to obtaining a replacement operation for the third target video template and the specified preview video, a third preview video corresponding to the third target video template is generated.

[0063] Here, the third target video template is a video template other than the first target video template and the second target video template among a group of video templates, and the replacement operation may be an operation in which the control button of the third target video template is dragged above the specified preview video, or an operation in which the third target video template is clicked (click, double-click, or long-pressed) and then the specified preview video is clicked.

[0064] In step 105, the designated preview video is replaced with the third preview video.

[0065] Here, the designated preview video is either the first preview video or the second preview video.

[0066] According to the above technical solution, when the number of preview videos displayed in the preview area is limited, a preview comparison can be performed between the first target video template and other video templates besides the second target video template by replacing them, thereby effectively improving the user experience during the video template selection process.

[0067] Selectively, the method further includes the following steps:

[0068] In response to obtaining position adjustment operations for the first and second preview videos to be adjusted, the display area in which the first and second preview videos are located is adjusted.

[0069] Here, the first preview video to be adjusted may be the first preview video or the second preview video, and the second preview video to be adjusted may be another preview video outside the first preview video within the preview area. The position adjustment operation may be an operation of dragging the video template corresponding to the first preview video to be adjusted onto the video template corresponding to the second preview video to be adjusted, or an operation of dragging the first preview video to be adjusted onto the second preview video to be adjusted.

[0070] According to the above technical solution, the display positions of multiple preview videos can be effectively adjusted to help users compare multiple preview videos, thereby effectively improving the efficiency of selecting video templates.

[0071] Selectively, each video template includes a volume control button, and the method further includes the following steps:

[0072] The system obtains the playback volume input using the volume control buttons corresponding to each preview video within the preview display area, and plays each preview video according to that corresponding playback volume.

[0073] Here, as shown in Figure 2, volume control buttons may be placed within the display window where each preview video is located. By using these volume control buttons corresponding to each preview video to control the playback volume of that preview video, users can adjust the playback volume of different preview videos in a personalized manner, effectively improving the user experience during the video template selection process.

[0074] Selectively, as shown in Figure 2, each video template may further include a "Use Template" button, which is displayed on the preview video screen of the corresponding video template, and the method further includes the following steps:

[0075] In response to receiving a use command triggered by using the template use button on the target preview video, only the target preview video is displayed in the video preview area, and in response to receiving a video generation command, the target preview video is saved.

[0076] Here, the user can trigger the input command by clicking the Use Template button, and after receiving the input command, the terminal can use the preview video corresponding to the clicked Use Template button as the target preview video and stop displaying preview videos other than the target preview video. The user can trigger the video generation command by clicking a predetermined save (or send) button, which may be an "x" symbol for closing the current interface.

[0077] According to the above technical solution, preview videos corresponding to unwanted video templates can be quickly closed, and the user's preferred target preview video can be conveniently and quickly saved, effectively improving the efficiency of video compositing and enhancing the user experience.

[0078] Figure 5 is a block diagram of a video preview device shown in an exemplary embodiment of the present invention, and as shown in Figure 5, the device is A first generation module 501 that generates and displays a first target interface in response to receiving a video editing command for a video to be edited, wherein the first target interface includes a template display area and a preview area, the template display area includes control buttons for a plurality of video templates, and the preview area includes a first preview video corresponding to the first target video template among the plurality of video templates, A second generation module 502 generates a second preview video corresponding to a second target video template in response to a user trigger operation on a control button corresponding to a second target video template among multiple video templates, The system may also include a first display module 503 that displays the first preview video and the second preview video in the preview area.

[0079] According to the above technical solution, by displaying the first and second preview videos in the preview area, it becomes easier for users to compare the effects of generating videos using different video templates. This improves the speed at which users can select video templates, enhances the efficiency of video compositing, and effectively improves the user experience.

[0080] Selectively, the first generation module 501 is, In response to receiving the video editing command, the system determines a first target video template from among multiple video templates.
