[0026] Before introducing a specific embodiment of the present invention, the application scenario of the present invention will be described as follows. The present invention can be applied to the video editing process, especially the scene of editing a video using a video template. At present, in the process of editing using a video template, usually, only one effect video corresponding to one video template can be previewed, but the visual difference between different video templates is not necessarily large, so there may be only a few frames with obvious features. When selecting a template, usually, the user needs to preview the video template one by one, which is time-consuming; moreover, the user can only preview one video template at a time, and after selecting a video template, it requires a certain loading time, so the user is likely to forget the video effect previewed before. Therefore, when the number of video templates is larger, it will inevitably take a very long time for the user to select a preferred video template, which is not conducive to improving the efficiency of video synthesis and is not conducive to improving the user experience.

[0027] In order to solve the above technical problems, the present invention provides a video preview method, an apparatus, a readable medium, and an electronic device, in which, in response to receiving a video editing command for a video to be edited, a first target interface is generated and displayed, where the first target interface includes a template display area and a preview area, the template display area includes control buttons of a plurality of video templates, the preview area includes a first preview video corresponding to a first target video template among the plurality of video templates, and in response to obtaining a user's trigger operation on a control button corresponding to a second target video template among the plurality of video templates, a second preview video corresponding to the second target video template is generated and displayed in the preview area, and by displaying the first preview video and the second preview video in the preview area in this manner, it is easy for a user to compare the effects of generating videos using different video templates, so as to improve a speed at which a user selects a video template, improve the efficiency of video synthesis, and effectively improve the user experience.

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

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

[0030] In step 101, in response to receiving a video editing command for a video to be edited, a 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 of a plurality of video templates, and the preview area includes a first preview video corresponding to a first target video template among the plurality of video templates.

[0032] By way of example, the video to be edited may be a game video obtained by screen recording, the video editing command may be triggered by a user clicking a stop recording button when recording the game screen, and the video to be edited may be a video captured by a camera of the terminal or a video obtained by other means and stored locally on the terminal.

[0033] It should be noted that when generating and displaying the first preview video on the first target interface, a loading animation of a video template can be combined, and as the loading progress of the video template changes, a predetermined cartoon image peels off a mask layer on the video, and the first preview video lights up and begins to play.

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

[0035] Here, the second target video template may be a video template other than the first video template among a plurality of video templates, and the trigger operation may be dragging (clicking, long pressing, or double clicking) a 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 possible embodiment of the step, the preview area may include a first display window and at least one second display window, the first display window may be used to display a first preview video, and the second display window may be used to display a second preview video, and 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 display window and the second display window are the same, and the predetermined size can be obtained by obtaining a target number of preview videos currently displayed in the preview area, and determining the predetermined size from a predetermined size correspondence relationship based on the target number.

[0039] It should be noted that the second target video template may be included in a plurality of ways, and when the second target video template is one, only one second preview video is included, and the first designated area may be the left side (or upper side) of the preview area, and the second designated area may be the right side (or lower side) of the preview area, as shown in a of FIG. 2 (FIG. 2 is a schematic diagram of a preview interface shown in an exemplary embodiment of the present invention). When two second target video templates are included, the first designated area may be the left center (or upper center) position of the preview area, and the second designated area may be the upper right side (or lower left side) or lower right side (or lower right side), as shown in b of FIG. When three second target video templates are included, the first designated area may be the upper left side position of the preview area, and the second designated area may be the upper right side, lower right side, or lower left side, as shown in c of FIG. 2.

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

[0041] According to the above technical solution, by displaying the first preview video and the second preview video in the preview area, it is easy for users to compare the effects of generating videos using different video templates, so that the speed at which users select video templates can be improved, the efficiency of video synthesis can be improved, and the user experience can be effectively improved.

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

[0043] At step 1011, in response to receiving the video editing command, a first target video template is determined from the plurality of said video templates.

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

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

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

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

[0048] In this step, when generating the first preview video, the first target video template is loaded, and then the first preview video can be generated by applying the first target video template onto the video to be edited.

[0049] It should be noted that when loading the first target video template, a video template loading animation can be combined to display relevant presentation of the template loading process, and as the video template loading progress changes, a predefined cartoon image peels off a mask layer on the video, and when it is determined to generate the first preview video, the first preview video will light up and start 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 display window may be used to display the first preview video.

[0052] According to the above technical solution, a first target video template that is closest to the duration of the video to be edited can be selected from a plurality of video templates, and a first preview video corresponding to the first target video template can be displayed in the first target interface when entering the first target interface, which can help users quickly select video templates, effectively improve the efficiency of template selection, improve the efficiency of video synthesis, and even effectively improve the user experience.

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

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

[0055] As an example, taking the example shown in step 1011 above, the arrangement order corresponding to the control buttons of the multiple video templates (i.e., video template A to video template F) in 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, the control buttons of multiple video templates can be displayed in the template display area in order of the smallest target difference, which can help users quickly select video templates, effectively improve the efficiency of template selection, improve the efficiency of video synthesis, and effectively improve the user experience.

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

[0058] An associated relationship between the first preview video, the second preview video and the playback progress bar is established so that the playback progress bar controls the playback progress of the first preview video and the second preview video simultaneously.

[0059] It should be noted that when a plurality of second preview videos are included, an association relationship between each of the second preview videos and the playback progress bar of the video to be edited can be established, thereby realizing the use of the playback progress bar of the video to be edited to control each preview video in the preview area; when each second preview video is added to the preview area, the first preview video and the second preview video are both played from their starting frames, so that the plurality of preview videos are played synchronously, effectively ensuring that the screens displayed by the plurality of preview videos currently displayed in the preview area are all identical, thus helping users to compare the display effects of the plurality of preview videos, and effectively improving the efficiency of video template selection.

[0060] According to the above technical solution, by establishing an association relationship between the first preview video, the second preview video and the playback progress bar of the video to be edited, it is possible to realize using the playback progress bar of the video to be edited to control the playback progress of the first preview video and the second preview video, which can effectively improve the video control efficiency, and also effectively improve the video template selection efficiency, which is helpful to improving the user experience.

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

[0062] At step 104, in response to obtaining a replacement operation for the third target video template and the designated 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 the multiple video templates, and the replacement operation may be an operation of dragging the control button of the third target video template above the designated preview video, or an operation of clicking the third target video template (which may be a click, double-click, or long press) and then clicking the designated preview video.

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

[0065] Here, the designated preview video is 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 replacement method can be used to perform preview comparison with video templates other than the first target video template and the second target video template, thereby effectively improving the user experience in the video template selection process.

[0067] Optionally, the method further comprises the steps of:

[0068] In response to acquiring a position adjustment operation action for the first adjustment-target preview video and the second adjustment-target preview video, the display area in which the first adjustment-target preview video and the second adjustment-target preview video are arranged is adjusted.

[0069] Here, the first adjustment target preview video may be the first preview video or the second preview video, and the second adjustment target preview video is another preview video in the preview area other than the first adjustment target preview video. The position adjustment operation may be an operation of dragging a video template corresponding to the first adjustment target preview video onto a video template corresponding to the second adjustment target preview video, or an operation of dragging the first adjustment target preview video onto the second adjustment target preview video.

[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, and the efficiency of video template selection can be effectively improved.

[0071] Optionally, each of the video templates includes a volume control button, and the method further includes the following steps:

[0072] A playback volume input using a volume control button corresponding to each preview video in the preview display area is obtained, and the preview video is played according to the playback volume corresponding to each preview video.

[0073] Here, as shown in FIG. 2, a volume control button may be provided in the display window in which each preview video is arranged, and a user may use the volume control button corresponding to each preview video to control the playback volume of the preview video, thereby adjusting the playback volume of different preview videos in a personalized manner, thereby effectively improving the user experience in the video template selection process.

[0074] Optionally, as shown in FIG. 2, each of the video templates may further include a use template button, which is displayed on a preview video screen of the corresponding video template, and the method further includes the steps of:

[0075] In response to receiving an input use command triggered by using a 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 click the template use button to trigger the input use command, and after the terminal obtains the input use command, the terminal can use the preview video corresponding to the clicked template use button as the target preview video and stop displaying preview videos other than the target preview video, and the user can click a predetermined save (or send) button to trigger the video generation command, and the predetermined save (or send) button may be an ``X'' symbol for closing the current interface.

[0077] According to the above technical solution, the preview video corresponding to the non-desired video template can be quickly closed, and the user's preferred target preview video can be conveniently and quickly saved, which can effectively improve the efficiency of video synthesis and improve the user experience.
