[0043] The target video editing template is used to indicate a filling slot of at least one video segment and an editing effect applied to the at least one video segment.

[0044] Wherein, a target video editing template is determined from multiple video editing templates based on the target video copy.

[0045] 103. Capture at least one material segment from the first video material.

[0046] The at least one material clip corresponds to a filling slot of the at least one video clip and is used to fill the target video editing template to form the at least one video clip.

[0047] It can be understood that because the target video editing template is used to indicate the filling slot of at least one video clip, it is necessary to extract at least one material clip from the first video material, and the at least one material clip corresponds one-to-one to the filling slot of at least one video clip.

[0048] 104. Generate a second video material according to the at least one material clip and the target video editing template.

[0049] The second video material is used to present the editing effect applied to the at least one material segment.

[0050] It can be understood that at least one material clip is filled into the filling slot of at least one video clip to generate a second material video, or, according to the target video editing template, at least one material clip is spliced ​​and an editing effect is applied to at least one material clip to obtain a second video material.

[0051] 105. Generate a target video by splicing the second video material in front of the first video material.

[0052] In the embodiment of the present disclosure, a video editing template is designed, which is used to indicate the filling slots of at least one video clip and the editing effects applied to the at least one video clip, and then a target video text corresponding to the first video material is obtained; a target video editing template is determined based on the target video text, and then a second video material corresponding to the first video material is generated according to the target video editing template, and the target video is generated by splicing the second video material in front of the first video material, thereby realizing automatic video editing of the first video material. There is no need for the user to manually clip the first video material, nor is there any need for the user to manually splice the clipped video segments, nor is there any need for the user to manually add editing effects to the clipped video segments to generate the second video material. At the same time, there is no need for the user to manually splice the second video material in front of the first video material to generate the target video. Therefore, the disclosed solution simplifies the user's operation process for video editing of the first video material, reduces the time consumption of video editing, and improves the processing efficiency of video editing.

[0053] In some embodiments of the present disclosure, steps 101 to 105 can be used to generate a header for the video material to be processed (hereinafter referred to as header video editing processing), wherein the first video material is the video material to be processed, the second video material is the header of the first video material, and the target video is the first video material including the header.

[0054] In some embodiments of the present disclosure, steps 101 to 105 can be used to generate chapters of the video material to be processed (hereinafter referred to as chapter video editing processing), wherein the first video material is one of the multiple chapters included in the video material to be processed, the second video material is a chapter introduction of the first video material, and the target video is the video material to be processed including multiple chapters. In this case, in the above step 101, it is necessary to first divide the video material to be processed into chapters to obtain multiple chapters. In the above step 105, it is necessary to splice the multiple chapters with the added chapter introductions to obtain the target video.

[0055] In some embodiments of the present disclosure, the above step 101 can be specifically implemented through the following steps 101a to 101b, or the above step 101 can be specifically implemented through the following steps 101c to 101e; the above step 105 can be specifically implemented through the following steps 105a to 105b.

[0056] 101a. Obtain the target video text of the video material to be processed.

[0057] 101b. Based on the target video text, divide the to-be-processed video material into a plurality of video materials, each of the plurality of video materials being a first video material.

[0058] It can be understood that the target video copy is the video copy of the video material to be processed. Then, combined with step 102, for chapter video editing processing, the video editing template of the chapter is determined based on the video copy of the video material to be processed, that is, the video editing templates corresponding to multiple video materials are the same.

[0059] 101c. Obtain the video material text to be processed of the video material to be processed.

[0060] 101d. Based on the text of the video material to be processed, divide the video material to be processed into multiple video materials.

[0061] Each of the multiple video materials is a first video material.

[0062] 101e. Obtain the target video text of the first video material.

[0063] It can be understood that the target video copy is the video copy of the first video material, and then combined with step 102, for the chapter video editing processing, the video editing template of the chapter is determined based on the video copy of the first video material, that is, the video editing templates corresponding to multiple video materials are determined according to the video copy of each video material. Therefore, the video editing templates corresponding to multiple video materials may be the same or different, and can be determined specifically according to actual conditions, which is not limited here.

[0064] Each of the multiple video materials is a chapter of the video material to be processed. Based on the voice information of the target video text, the video material to be processed can be divided into chapters to obtain multiple video materials, each of which is a part of the video material to be processed that describes different things or events.

[0065] The plurality of video materials are each a first video material, and the above steps 102 to 104 are performed on each of the plurality of video materials to obtain a second video material corresponding to each video material.

[0066] 105a. Generate an edited video corresponding to the first video material by splicing the second video material in front of the first video material, so as to generate an edited video corresponding to each video material.

[0067] The edited video corresponding to the first video material is the video material after adding chapter introductions to the first video material.

[0068] 105b. Splice the edited videos corresponding to each video material to obtain the target video.

[0069] In the embodiment of the present disclosure, the target video is obtained by splicing the edited videos corresponding to the plurality of video materials, that is, the video material after adding chapters to the video material to be processed is obtained.

[0070] In the embodiment of the present disclosure, in the process of adding chapters to the video material to be processed, the same video editing template can be determined for multiple chapters based on the video copy of the video material to be processed, or video editing templates can be determined for different chapters based on the video copy of the chapters. The specific details can be determined based on actual conditions and are not limited here.

[0071] In some embodiments of the present disclosure, the target video editing template is further used to indicate the video title to fill the slot; the video editing method provided by the embodiment of the present disclosure may further include the following step 106, and the above step 104 may be specifically implemented by the following step 104a.

[0072] 106. Generate a video title for the first video material according to the video text of the first video material, where the video title is used to fill the video title filling slot.

[0073] The video title is used to summarize the main information expressed by the first video material.

[0074] 104a: Generate a second video material according to the at least one material clip, the video title, and the target video editing template.

[0075] The second video material is used to present the editing effect applied to the at least one material segment and the video title.

[0076] In the disclosed embodiment, the video editing template includes a video title filling slot, which can make the generated second video material include the information mainly expressed by the first video material, making it easier for users to understand what the first video material is trying to express.

[0077] In some embodiments of the present disclosure, the above step 102 can be specifically implemented through the following steps 102a and 102b.

[0078] 102a. Determine the category label of the category to which the target video copy belongs.

[0079] Among them, category tags may include video blogs, technology, fashion, film and television, animation, news, etc. If the video copy has no obvious category characteristics, the video copy will be labeled with a general tag.

[0080] It can be understood that the category to which the video copy belongs is the category to which the video material belongs.

[0081] In some embodiments of the present disclosure, step 102a can also be replaced by determining a category label for the category to which the first video material belongs. This can be accomplished by extracting a preset number of video frames from the first video material and then performing content recognition on the preset number of video frames to determine the category to which the first video material belongs, thereby obtaining a category label for the category to which the first video material belongs.

[0082] 102b. Determine a target video editing template corresponding to the category label from a plurality of video editing templates, where different category labels correspond to different video editing templates.

[0083] Among them, different category labels correspond to different video editing templates, and the target video editing template includes a video title filling slot and at least one video clip filling slot. The video title filling slot is used to indicate the video title of the first video material, and each video clip filling slot is used to indicate a video clip of the first video material.

[0084] It can be understood that multiple correspondences are stored in the electronic device, each correspondence is used to indicate a category label and at least one video editing template corresponding to the category label; each correspondence can also be used to indicate a video editing template and a category label corresponding to the video editing template.

[0085] In some embodiments of the present disclosure, a category label may correspond to at least one video editing template, and a video editing template may also correspond to one or more category labels.

[0086] The multiple video editing templates in the above step 102b correspond to different category labels respectively. If there is only one video editing template corresponding to the category label among the multiple video editing templates, then the one video editing template is the target video editing template. If there are multiple editing templates corresponding to the category label among the multiple video editing templates, then you can arbitrarily select one video editing template from the multiple editing templates as the target video editing template; you can also display multiple template identifiers corresponding to the multiple editing templates to the user (which can also include an introduction to the differences between different template identifiers), and then determine the video editing template corresponding to the template identifier selected by the user from the multiple template identifiers as the target video editing template; the specific determination can be based on actual conditions and is not limited here.

[0087] In the disclosed embodiment, a video editing template is determined based on the category label of the category to which the video copy belongs, which can increase the diversity of video editing and improve user experience.

[0088] It can be understood that when the video editing process is a title video editing process, the target video editing template is a title video editing template, the title video editing template includes a title slot and a filling slot for at least one video clip, the video title of the first video material is the title title, the above step 104 is specifically based on the title video editing template, the title is filled into the title slot, and at least one material clip is filled into the filling slot of the at least one video clip to generate the target title, the above step 105 is specifically to synthesize the target title and the first video material into the target video.

[0089] It can be understood that when the video editing process is a chapter video editing process, the target video editing template is a chapter video editing template. The chapter video editing template includes a chapter title slot and a filling slot for at least one video clip. The video title of the first video material is the chapter title. The above step 104 is specifically based on the chapter video editing template, filling the chapter title into the chapter title slot, and filling at least one material clip into the filling slot of the at least one video clip to generate a target chapter introduction. The above step 105 is specifically splicing the chapter introduction before the first video material to obtain the edited video corresponding to the first video material (a chapter including a chapter introduction), and then splicing the edited videos corresponding to each video material to obtain the target video.

[0090] In the disclosed embodiment, a target video editing template that matches the category label is determined by using the category label of the video text of the video material to be processed, and then at least one material segment required by the target video editing template is extracted from the first video material, and the video title of the first video material required by the target video editing template is obtained based on the video text of the first video material, and then the video title and at least one material segment of the first video material are filled into the target video editing template to generate a second video material corresponding to the first video material, so as to synthesize the target video based on the second video material and the first video material. In this way, by setting different video editing templates for different categories of video materials to be processed, and then performing video editing on the video materials to be processed according to the video editing template that matches the category to which the video material to be processed belongs, automatic video editing of the video materials to be processed is achieved, which can improve the video editing efficiency of the video materials to be processed.

[0091] In some embodiments of the present disclosure, the filling slot of each video segment is also used to indicate the duration of the corresponding video segment; the above-mentioned step 103 can be specifically carried out through the following steps 103a to 103f.

[0092] 103a. Slice the first video material to obtain at least one slice.

[0093] In some embodiments of the present disclosure, the first video material may be sliced ​​based on the continuity of the video image. For example, the first video material may be sliced ​​using the locations where scene changes or shot changes are identified in the first video material as slicing points to obtain at least one slice.

[0094] In some embodiments of the present disclosure, the first video material may also be sliced ​​according to a preset duration (which may be determined based on actual conditions and is not limited here).

[0095] 103b. Perform highlight segment extraction processing on the at least one slice to obtain at least one highlight segment.

[0096] The at least one slice corresponds to the at least one highlight segment in a one-to-one manner.

[0097] In the disclosed embodiment, the specific process of extracting highlight segments is not limited and can be determined based on actual conditions.

[0098] Exemplarily, highlight segments may be extracted from slices using a related highlight segment extraction method, or using a highlight segment extraction model.

[0099] In some embodiments of the present application, extracting highlight segments for a slice (hereinafter referred to as a target slice) may be as follows: scoring each frame in the target slice, determining the frame with the highest score as the highlight frame, and then extending based on this highlight frame (extracting a continuous preset number of video frames forward and / or backward) to obtain the highlight segment corresponding to the target slice.

[0100] Among them, the scoring will be based on the composition, color, aesthetics and other dimensions of the video frame.

[0101] For example, if a 1-second highlight clip is needed, based on the highlight frame with the highest score, 0.5-second video frames can be taken forward and backward to obtain a 1-second highlight clip.

[0102] In some embodiments of the present disclosure, a highlight clip is a video clip that includes a highlight event. A highlight event is a special plot such as a person, thing, action, story and / or sound effect in a video that attracts the audience. Different highlight events can be defined in different types of videos. For example, in a football game video, goals, tackles and saves are defined as highlight events; in a battle-type operation game video, the release actions of various skills are defined as highlight events; compared with other relatively bland parts of the video, highlight events can arouse people's interest and attention.

[0103] In some embodiments of the present disclosure, a highlight segment refers to a segment of video material to be processed that includes a highlight event and has relatively bright colors and high picture quality.

[0104] Exemplarily, extracting a highlight segment for a slice (hereinafter referred to as a target slice) can be as follows: according to the category label of the category to which the first video material belongs, determining multiple highlight events that match the category label, and determining the segment of the highlight event among the multiple highlight events identified in the target slice as the highlight segment.

[0105] 103c. Determine N first material segments from the at least one highlight segment.

[0106] The duration of each first material segment is the duration of a video segment, each first material segment corresponds to a highlight segment, and N is a natural number;

[0107] Each first material segment is a highlight segment of the at least one highlight segment, which is obtained by processing according to the duration of a video segment, and N is a natural number.

[0108] It can be understood that the N first material clips are recorded as N of the at least one material clip.

[0109] In some embodiments of the present disclosure, each highlight segment in at least one highlight segment is scored. When determining N first material segments from the at least one highlight segment, the first material segment is preferentially selected from the highlight segments with the highest scores and those whose durations match the durations of the corresponding video segments. Highlight segments whose durations are shorter than the durations of any video segments are discarded, and from among the highlight segments whose durations are equal to or greater than the durations of the corresponding video segments, the highest-scoring highlight segments that match the durations of the corresponding video segments are selected as the first material segments.

[0110] In Example 1, the process for obtaining a first clip is to select, from among at least one highlight clip, a highlight clip with a duration greater than or equal to the corresponding duration and the highest score, excluding highlight clips already obtained from the first clip, to obtain the first clip. For example, the at least one highlight clip includes three highlight clips: 10s highlight clip 1, 15s highlight clip 2, 8s highlight clip 3, and 6s highlight clip 4. The scores of these four highlight clips are, from highest to lowest, highlight clip 3, highlight clip 2, highlight clip 4, and highlight clip 1. At least one video clip (hereinafter referred to as M video clips) includes clip a with a duration of 10s, clip b with a duration of 6s, and clip c with a duration of 8s. Clip a is first extracted from highlight clip 2, clip b is then extracted from highlight clip 3, and finally clip c is extracted from highlight clip 1. The extracted clips a, b, and c constitute the three first clips.

[0111] 103d. When N is less than M, determine MN second material segments from the first video material.

[0112] The duration of each second material segment is the duration of a video segment other than the video segments corresponding to the N first material segments, M is the number of the at least one material segment, and M is a positive integer.

[0113] Each second material segment is the first video material, and is obtained by processing according to the duration of a video segment among the at least one video segment, excluding the duration of the video segment corresponding to the N first material segments.

[0114] It can be understood that the MN second material clips are the remaining MN material clips in the at least one material clip (excluding the N first material clips).

[0115] 103e. Determine the N first material clips and the MN second material clips as the at least one material clip.

[0116] The N first material segments extracted above are the optimal material segments selected from the first video material. When N is less than M, it is necessary to select suboptimal material segments from the first video material again.

[0117] Example 2, for the above steps 103d and 103e, continuing from the above example 1, M is 5, and at least one video clip (M video clips) also includes a material clip d with a duration of 9 seconds, and a material clip e with a duration of 12 seconds. Then it is necessary to determine two second material clips from the first video material as material clip d and material clip e, one of which has a duration of 9 seconds and the other has a duration of 12 seconds. Highlight clip 4 (duration of 6 seconds) does not meet the conditions for extracting the second material clip, so it is necessary to determine two second material clips from the first video material. Then the three first material clips and two second material clips extracted above are the five material clips required by the target video editing template.

[0118] 103f. When N is equal to M, determine the N first material clips as the at least one material clip.

[0119] Example 3, continuing from the above Example 1, M is 3, and the three first material clips extracted above are the three material clips required by the target video editing template.

[0120] In the embodiment of the present disclosure, through the above steps 103a to 103f, based on the length of each video clip, at least one material clip (at least one video clip) that meets the requirements of the target video editing template can be obtained, and then a second video material can be generated based on the target video editing template and at least one material clip, thereby obtaining a target video that meets the requirements, which can improve the processing efficiency of video editing.

[0121] In some embodiments of the present disclosure, priority is given to ensuring that each second material segment does not duplicate any first material segment, and that each second material segment does not duplicate each other. If this cannot be guaranteed, efforts are made to ensure that each second material segment is not completely identical to any first material segment, and that each second material segment is not completely identical to each other. For example, step 103d can be implemented through steps 103d1 to 103d3.

[0122] 103d1. When the video duration of the remaining videos in the first video material except the N first material segments is greater than the target duration, determine the MN second material segments from the remaining videos.

[0123] The target duration is the sum of the durations of the video segments in the at least one video segment excluding the video segments corresponding to the N first material segments. In other words, the target duration is the sum of the durations of the M video segments in the M material segments excluding the video segments corresponding to the N first material segments.

[0124] 103d2. When the video duration of the remaining video is less than or equal to the target duration, determine K second material segments from the remaining video.

[0125] Wherein, K is a natural number less than or equal to MN. K can be equal to 0 or a positive integer less than or equal to MN.

[0126] 103d3. Determine MNK second material segments from the first video material.

[0127] In the embodiment of the present disclosure, the logic for determining MN second material segments is to preferentially select suboptimal video segments from the remaining videos of the first video material excluding the N first material segments as the second material segments. When the duration of the remaining video is greater than the target duration, MN second material segments are selected from the remaining video, and the obtained at least one video segment (at least one material segment) does not repeat with each other. When the duration of the remaining video is less than or equal to the target duration, K second material segments are preferentially determined from the remaining video, and there is no duplication between the K second material segments, and the K second material segments do not repeat with the above-mentioned N first material segments, and then MNK second material segments are determined from the first video material, and each of the MNK second material segments may overlap with one or more material segments among the N first material segments and the K second material segments.

[0128] For example, assuming that the length of the first video material is 20 seconds, the first video material needs to be edited for the title video, and the matched title video editing template requires 4 (M) video clips, each of which is 6 seconds long. The first video material is sliced ​​to obtain 2 slices, and 2 (N) first material clips (6s*2=12s) are obtained based on the 2 slices. Then, the remaining video of the first video material except the 2 first material clips is extracted to obtain 1 (K) second material clip (6s). Because the remaining video of the first video material except the 2 first material clips and 1 second material clip that have been obtained is only 2 seconds, it is not enough to extract another second material clip. Therefore, it is necessary to extract 1 (MNK) second material clip from the first video material, which has repeated content with at least one of the 2 first material clips and 1 second material clip extracted previously, so that the title video editing template requires 4 video clips.

[0129] In the embodiment of the present disclosure, by extracting MN second material segments according to the method provided in the above steps 103d1 to 103d3, second material segments that better meet the needs can be obtained. Finally, the second video material synthesized based on at least one video segment (i.e., N first material segments and MN second material segments) has the least number of repeated frames, which can improve the user experience.

[0130] In some embodiments of the present disclosure, the filling slot of each video segment is also used to indicate the arrangement order of the corresponding video segments. The above step 104 can be specifically implemented through the following step 104b.

[0131] 104b. Based on the target video editing template, synthesize the at least one material segment according to the arrangement order of the corresponding video segments to generate a second video material.

[0132] In the disclosed embodiment, if the fill slots of at least one video clip in the target video editing template are ordered, the arrangement order is determined based on the order of the fill slots of the at least one video clip, and the order of extracting the at least one material clip is also determined based on the order of the fill slots of the at least one video clip. By filling the fill slots of the at least one video clip with the at least one material clip according to the arrangement order of the corresponding material clips, a second video material that better meets the requirements can be obtained.

[0133] In some embodiments of the present disclosure, if there is no order in the filling slots of each video clip, the at least one clip and the video title of the first video material can be synthesized into the second video material according to the timestamp of the first frame of each clip in the at least one extracted clip.

[0134] In some embodiments of the present disclosure, the above step 101 may further include the following step 101f, and after the above step 105, the following step 107 may further be included.

[0135] 101f. In response to a triggering operation on a video editing control in a video editing panel, obtaining a first video material and a target video text corresponding to the first video material to enter a video editing process;

[0136] 107. Display the target video.

[0137] In the disclosed embodiment, the target video is displayed to facilitate users to view the video editing effect.

[0138] In some embodiments of the present disclosure, before the above 101f, the video editing method provided by the embodiment of the present application may further include the following step 108.

[0139] 108. In response to a triggering operation on a video processing control displayed on the video editing interface, display a video editing panel.

[0140] Among them, the video editing panel displays video editing controls, which include header editing controls or chapter editing controls. The header editing controls are used to indicate header video editing processing, and the chapter editing controls are used to indicate chapter video editing processing.

[0141] In some embodiments of the present disclosure, the video editing panel may display only the title editing control, or only the chapter editing control, or both the title editing control and the chapter editing control at the same time. Other editing controls may also be displayed in the video editing panel. The specific details may be determined based on actual conditions and are not limited here.

[0142] In some embodiments of the present disclosure, one or more video editing controls may be displayed in a video editing panel. The video editing panel may display one or more title editing controls, or one or more chapter editing controls. The specific details may be determined based on actual circumstances and are not limited here. Different title editing controls correspond to different logic for editing the title video. Different chapter editing controls correspond to different logic for editing the chapter video.

[0143] In some embodiments of the present disclosure, a video editing control (a header editing control and / or a chapter editing control) may be a control with a switch. When the video editing function is used for the first time, the switch of the video editing control (hereinafter referred to as the video editing switch) is turned off by default. When the video editing function is used subsequently, it is displayed according to the recorded state of the video editing switch. That is, if the last recorded state of the video editing switch is on, it is turned on by default this time. If the last recorded state of the video editing switch is off, it is turned off by default this time.

[0144] In some embodiments of the present disclosure, the video editing controls can also be set according to whether the video editing interface is displayed in landscape or portrait mode. For example, when the video editing interface is displayed in portrait mode, the video editing controls are grayed out (i.e., video editing cannot be performed on the video material to be processed based on the video editing controls). At this time, when you click the switch, a pop-up window will pop up prompting "Currently only supports landscape video editing."

[0145] It can be understood that if the video editing control is a header editing control, then in response to the triggering operation of the header editing control, based on the header video editing processing indicated by the header editing control, the video material to be processed is edited to generate a target video, which includes a synthesized header mixed-cut clip.

[0146] It can be understood that if the video editing control is a chapter editing control, then in response to the triggering operation of the chapter editing control, based on the chapter video editing processing indicated by the chapter editing control, video editing processing is performed on the video material to be processed to generate a target video. The target video includes multiple chapters, and each chapter includes a synthetic chapter mixed clip.

[0147] In this way, this solution can trigger automatic video editing of the video material to be processed by displaying the video processing controls on the video editing interface, and then triggering the display of the video editing panel through the video processing controls, and by triggering the video editing controls displayed in the video editing panel. There is no need for users to select and match suitable materials in the huge material library, and make style adjustments, etc. to realize video editing of the video material to be processed. It simplifies the user's operation process for video editing of the video material to be processed (header video editing or chapter video editing), reduces the time consumption of video editing of the video material to be processed, and improves the processing efficiency of video editing of the video material to be processed.

[0148] In some embodiments of the present disclosure, a commercial material filtering option is also displayed in the video editing panel, which is not selected by default (i.e., the commercial material filtering function is turned off by default). After the commercial material filtering function is turned on, the video editor only returns commercially available materials.

[0149] In some embodiments of the present disclosure, when the video editing panel is displayed for the first time, the commercial material screening option is unselected by default. When the video editing panel is displayed subsequently, it is displayed according to the status of the last recorded commercial material screening option. That is, if the status of the last recorded commercial material screening option is unselected, it is unselected by default this time; if the status of the last recorded commercial material screening option is selected, it is selected by default this time.

[0150] In some embodiments of the present disclosure, the video editing panel may also display text editing controls (for video editing of text in subtitles, picture-in-picture, etc.) and sound effect video editing controls (when the subtitles include keywords that match sound effects, corresponding sound effects are added when the keywords are displayed). The specific details can be determined based on actual conditions and are not limited here.

[0151] In some embodiments of the present disclosure, when a text editing control is displayed in the video editing panel, a Delete Existing Subtitles option is also displayed for the text editing control in the video editing panel (selected by default, i.e., the Delete Existing Subtitles function is enabled by default). The Delete Existing Subtitles option in a selected state is used to indicate that the existing subtitles of the video material to be processed are deleted before text editing is performed on the video material to be processed, and the Delete Existing Subtitles option in an unselected state is used to indicate that the existing subtitles of the video material to be processed are used for video editing when text editing is performed on the video material to be processed.

[0152] In some embodiments of the present disclosure, the video editing panel also displays a function introduction icon corresponding to each video editing control. The function introduction icon is used to trigger the display of a function introduction to the video editing mode indicated by the corresponding video editing control. The function introduction includes a text-based introduction and / or an animated graphic-based introduction. In this way, if the user does not understand the video editing mode corresponding to each video editing control, the function introduction to the video editing mode indicated by the video editing control can be triggered by triggering the function introduction icon corresponding to the video editing control, thereby facilitating user understanding and use and improving user experience.

[0153] In some embodiments of the present disclosure, a function introduction interface corresponding to the function introduction icon is displayed in a floating manner in the video editing panel. The function introduction interface can be a pop-up window display or the following function introduction floating layer, which is not limited here.

[0154] In some embodiments of the present disclosure, the above step 108 can be specifically implemented through the following steps 108a and 108b.

[0155] 108a. In response to a triggering operation on a video processing control displayed on the video editing interface, a function introduction floating layer is displayed.

[0156] Among them, the function introduction floating layer is used to display the entry control of the video editing panel and the function introduction of the video editing process indicated by the video editing control. The function introduction includes a text introduction and / or an animated image introduction.

[0157] In some embodiments of the present disclosure, when the video editing panel includes multiple video editing controls, the function introduction corresponding to each video editing control in the function introduction floating layer can be displayed separately (the function introduction corresponding to different video editing controls can be switched through a switching operation), and the function introduction corresponding to each video editing control in the function introduction floating layer can also be displayed at the same time. The specific details can be determined based on actual conditions and are not limited here.

[0158] Among them, the specific function introduction can be set according to the corresponding video editing control and is not limited here.

[0159] Exemplarily, the function introduction floating layer is a half-screen function introduction floating layer. Specifically, an animated image introduction corresponding to a video editing control is displayed above the function introduction floating layer, and a text introduction corresponding to the video editing control is displayed below. Users can switch the animated image introductions corresponding to different video editing controls by sliding left and right. After the animated image introduction is switched, the text introduction below is synchronously updated.

[0160] 108b. In response to a triggering operation on the entry control, display the video editing panel.

[0161] Exemplarily, the entry control may be a “try it” control.

[0162] In some embodiments of the present disclosure, it can be arranged that when a new user (after downloading and installing) uses the video editing function for the first time, the above-mentioned step 108 includes the above-mentioned step 108a and step 108b. When an old user uses the video editing function, the video editing panel is directly displayed by triggering the video processing control, and the above-mentioned function introduction floating layer is not displayed.

[0163] In the embodiment of the present disclosure, before displaying the video editing panel, displaying a function introduction floating layer helps the user understand and compare the video editing processing corresponding to each video editing control, and then facilitates the subsequent selection of which video editing control to use for video editing processing of the video material to be processed, which can improve the user experience.

[0164] In some embodiments of the present disclosure, the above step 101f can be specifically carried out through the following steps 201 to 205.

[0165] 201. In response to a triggering operation on the video editing control, determine whether a video editing function has been authorized.

[0166] If it is determined that the video editing function is not authorized, the following steps 202 to 205 are executed; if it is determined that the video editing function is authorized, the following step 204 is executed.

[0167] 202. If the video editing function is not authorized, an authorization pop-up window is displayed, in which an authorization option and a non-authorization option are displayed.

[0168] The authorization option is used to indicate that the video editing function is authorized, and the non-authorization option is used to indicate that the video editing function is not authorized.

[0169] Exemplarily, the authorization pop-up window may include text-based introduction information about the video editing function, as well as an "Allow" option and a "Do Not Allow" option, wherein the "Allow" option corresponds to the authorization option, and the "Do Not Allow" option corresponds to the non-authorization option.

[0170] 203. In response to a triggering operation on the authorization option, determine to authorize the video editing function.

[0171] In response to the triggering operation of the authorization option, the video editing function is authorized for the electronic device, and the following step 204 is executed.

[0172] 204. If the video editing function is authorized, perform video editing on the video material to be processed based on the video editing control to generate the target video.

[0173] 205. In response to the triggering operation of the unauthorized option, prohibiting video editing processing of the video material to be processed.

[0174] It can be understood that in response to the triggering operation of the unauthorized option, the electronic device may not perform video editing on the video material to be processed, and may also display a prompt message, which is used to prompt that the video editing function cannot be used without authorization.

[0175] It is understood that when the video editing control is clicked, if it is detected that the electronic device is not authorized for the video editing function, an authorization pop-up window will pop up. Select the authorization option to start video editing of the video material to be processed. Select the unauthorized option to close the authorization pop-up window and not start (prohibit) video editing of the video material to be processed.

[0176] In some embodiments of the present disclosure, if the authorization option is selected this time, the authorization pop-up window will not pop up the next time the video editing function is used; if the non-authorization option is selected this time, the authorization pop-up window will still pop up the next time the video editing function is used, and the user can only use the video editing function after selecting the authorization option.

[0177] In the embodiment of the present disclosure, by setting the video editing function to be allowed when authorized, and prohibited when not authorized, the user's safety can be guaranteed, user misoperation can be avoided, and the user experience can be improved.

[0178] In some embodiments of the present disclosure, it is also possible to determine whether the video editing function has been authorized in response to a triggering operation of a video processing control. If the video editing function has not been authorized, an authorization pop-up window is displayed, in which an authorization option and a non-authorization option are displayed. If the video editing function has been authorized, a video editing panel is displayed. The specific details can be determined based on actual conditions and are not limited here.

[0179] In some embodiments of the present disclosure, the video editing method provided by the embodiments of the present disclosure may further include at least one of the following steps 109 to 111.

[0180] 109. In response to the triggering operation of the cancel control, the video editing process is stopped and the performed video editing results are cleared.

[0181] It can be understood that, in the process of performing video editing on the video material to be processed, in response to the triggering operation of the cancel control, the process of performing video editing on the video material to be processed is stopped, and the performed video editing results are cleared.

[0182] The cancel control is used to end the video editing process.

[0183] It is understood that the video editing method provided by the embodiment of the present disclosure supports terminating the video editing process during the video editing process. In this way, when the user suddenly does not want to continue the video editing process, the video editing process can be terminated by triggering the cancel control, which can improve the user experience.

[0184] 110. In response to a triggering operation on a target control, the video editing process is switched to background execution, and the progress of the video editing process is displayed at a target location.

[0185] It can be understood that in the process of video editing the video material to be processed, in response to the triggering operation of the target control, the process of video editing the video material to be processed will be switched to background execution, and the process progress of video editing the video material to be processed will be displayed at a preset position.

[0186] The process progress may be a progress percentage, or may be process description information of the current processing stage in the video editing process.

[0187] The target control is a control for switching the video editing process to background execution. For example, the target control can be a control for switching to the tool homepage of an application with video editing functions, a control for switching to the homepage of an electronic device, or other types of controls. The specific target control can be determined based on actual conditions and is not limited here.

[0188] It is understood that the video editing method provided by the embodiment of the present disclosure supports switching the video editing process to the background during the video editing process. For example, during the video editing process, by triggering the operation of exiting to the tool homepage, the tool homepage is displayed, and the video editing process is kept running in the background.

[0189] Among them, the preset position can be the draft cover of the tool homepage, or it can be a hanging window control displayed in an application with video editing function, or it can be a hanging window control displayed on an electronic device, or it can be other locations or areas. The specific location can be determined according to actual conditions and is not limited here.

[0190] Exemplarily, in response to a trigger operation of exiting to the tool homepage, the video editing process is kept running in the background, and the progress is displayed on the draft cover of the tool homepage.

[0191] The disclosed embodiment supports switching the video editing process to background execution, so that the user can also perform other operations during the video editing process of the video material to be processed, which can improve the user experience.

[0192] 111. During the process of video editing the video material to be processed, a loading animation is displayed, where the loading animation includes process description information of the video editing process for the video material to be processed.

[0193] In some embodiments of the present disclosure, the loading animation may be scrolling the process description information once every preset time period (such as 5 seconds) (ie, switching to display the process description information).

[0194] In some embodiments of the present disclosure, the loading animation may also display process description information in real time according to the actual video editing process, that is, the process description information of the current stage of the video editing process is displayed.

[0195] Exemplarily, the process description information can be "Acquiring video text...", "Determining the category label of the category to which the video belongs...", "Matching the video editing template corresponding to the category label...", "Extracting highlight clips...", etc. The specific process description information can be determined based on actual conditions and is not limited here.

[0196] In the disclosed embodiment, during the video editing process, displaying a loading animation can help users understand the general process of the video editing process and improve the user experience.

[0197] In some embodiments of the present disclosure, the video editing method provided by the embodiments of the present disclosure may further include at least one of the following steps 112 and 113.

[0198] 112. Display target prompt information.

[0199] Among them, when the video editing processing of the video material to be processed is successful, the target prompt information is used to prompt that the video editing processing of the video material to be processed is successful; when the video editing processing of the video material to be processed fails, the target prompt information is used to prompt that the video editing processing of the video material to be processed fails, and / or the reason for the failure of video editing processing of the video material to be processed.

[0200] In the embodiment of the present disclosure, after the video material to be processed is successfully edited (the material is added successfully), a prompt message "Video editing successful" or "Video editing processing successful" may be popped up.

[0201] In the embodiment of the present disclosure, after the video editing process of the video material to be processed fails (the adding of the material fails), a prompt message of "Video editing failed" or "Video editing process failed" may be popped up.

[0202] In some embodiments of the present disclosure, in the event that video editing fails, the reason for the failure may also be prompted. For example, if the second video material (title or chapter clip) cannot be returned due to the lack of audio content, a pop-up window may prompt "No speech content was recognized, and the title and chapter cannot be added for the time being"; if the recognition fails due to a network problem, a pop-up window may prompt "Network error, please try again."

[0203] In the disclosed embodiment, by displaying target prompt information, the user can be promptly prompted with the result of the video editing process, which facilitates the user to perform subsequent operations and improves the user experience.

[0204] 113. Display target status information.

[0205] Among them, when the video editing processing of the video material to be processed is successful, the target status information is used to indicate that the video editing processing of the video material to be processed is successful; when the video editing processing of the video material to be processed fails, the target status information is used to indicate that the video editing processing of the video material to be processed fails.

[0206] The disclosed embodiment supports displaying target status information corresponding to the success or failure of video editing processing at a preset position (refer to the above description of the preset position, which will not be repeated here). In this way, the user can be prompted whether the video editing processing of the video material to be processed is successful or failed. Furthermore, when the user cannot pay attention to the video editing process of the video material to be processed in real time, the user can understand the result of the video editing processing of the video material to be processed based on the target status information, which can improve the user experience.

[0207] In the disclosed embodiments, target state information may be displayed at a preset location for a certain period of time. For example, the target state information may be displayed at the preset location for the lifecycle of the corresponding application and may no longer be displayed after the application is restarted. The target state information may also be undisplayed after entering the timeline editing panel.

[0208] In the embodiment of the present disclosure, the target status information indicating the failure of video editing processing can also be cancelled after the user triggers the process of re-editing the video material to be processed through a trigger operation (such as clicking a retry control, clicking a redo control, or clicking any video editing processing control).

[0209] In some embodiments of the present disclosure, after the above step 113, the video editing method provided by the embodiments of the present disclosure may further include any one of the following steps 114 to 117.

[0210] 114. When it is detected that the application corresponding to the video editing function is closed, clear the target status information.

[0211] 115. When detecting that the timeline editing panel of the video editing interface is displayed, clear the target state information and position the timeline preview axis to the first position on the timeline where video editing has been performed.

[0212] Among them, positioning the timeline preview axis to the first position on the timeline where video editing has been performed can facilitate the user to determine at which position the video editing process was started, thereby improving the user experience.

[0213] 116. When it is detected that video editing is to be performed again on the video material to be processed, the target state information and the target video are cleared.

[0214] Among them, the video editing process is performed again on the video material to be processed. This can be done by using the video editor again after the video editor successfully adds the material; or by clicking the redo control, which is not limited here.

[0215] Clearing the target status information and the target video automatically clears the results of the previous video editing process, effectively overwriting the old results with the new results. This prevents the results of the two video editing processes from being mixed together, resulting in the final video editing result containing different editing styles and degrading the user experience.

[0216] 117. When it is detected that the video editing process performed on the video material to be processed is canceled, the target video is cleared.

[0217] The embodiment of the present disclosure supports the operation of undoing the video editing process that was previously performed.

[0218] It can be understood that adding materials using video editing is a whole operation step. When the user clicks the undo control, all video editing materials generated by the previous video editing process must be completely removed.

[0219] In some embodiments of the present disclosure, a free icon can be displayed at the video processing control according to actual needs, and the function can be used normally after clicking it.

[0220] For example, as shown in FIG2 , the area indicated by the mark “21” is the area for displaying the video material to be processed, the area indicated by the mark “22” is the timeline editing panel, and the area indicated by the mark “23” is the toolbar area for editing processing, wherein the toolbar area includes a “Video Processing” control. Clicking the “Video Processing” control shown in FIG2 displays a function introduction floating layer as indicated by the mark “31” in FIG3 , wherein the function introduction floating layer includes an introduction area in the form of an animated image for the video editing control 1 as indicated by the mark “311”, an introduction area in the form of a text for the video editing control 1 as indicated by the mark “312”, and a “Try It Out” control as indicated by the mark “313”. Click the "Try It" control shown in Figure 3 to display the video editing panel indicated by the mark "41" in Figure 4. The video editing panel includes the title editing control 1 (the switch of the current title editing control 1 is on, that is, the title editing control 1 is selected), the function introduction icon 1 corresponding to the title editing control 1, the chapter editing control 2 (the switch of the current chapter editing control 2 is off, that is, the chapter editing control 2 is not selected), the function introduction icon 2 corresponding to the chapter editing control 2, and the "Start" control. Click the "Start" control shown in Figure 4 to display the video editing loading animation area indicated by the mark "51" in Figure 5. At the same time, a pop-up window is displayed to prompt "Video editing still needs to run for a while, do you need to return to the tool homepage and run it in the background?" The user can choose "Run in the background" or "Wait" according to the prompt information.
