As an example, prior to a video editing operation submitted in a video editing script template in response to at least one of the first account number and the second account number, may further include: inquiring the state of a first shot picture, wherein the first shot picture is a shot picture edited by the video editing operation request in the video editing script template or a shot picture corresponding to a parameter edited by the video editing operation request in the video editing script template; determining that a process responsive to a video editing operation is to be performed when both a first lens view and a second lens view related to the first lens view are in an unedited state; and when the first lens picture and a second lens picture related to the first lens picture are in an editing state, displaying first prompt information, wherein the first prompt information is used for prompting that the video editing operation cannot be immediately responded due to editing conflict.

For example, the first shot may be any shot in the video editing script template, or may be a shot specified by the first account or the second account.

For example, the first prompt message is further used to prompt the first lens picture, the second lens picture, the parameter corresponding to the first lens picture, or the parameter corresponding to the second lens picture to be in the editing state; the first prompt message may further include an account number that is editing the first shot picture, the second shot picture, the parameter corresponding to the first shot picture, or the parameter corresponding to the second shot picture.

For example, when the first shot screen is updated from the editing state to the non-editing state, it may be that the editing of the first shot screen is completed or the editing of the first shot screen is cancelled, and if the editing of the first shot screen is completed, the editing result needs to be synchronously displayed in the video editing script template, and prompt information capable of responding to the video editing operation is displayed; and if the first shot picture editing is cancelled, cancelling the editing result in the video editing script template and displaying prompt information capable of responding to the video editing operation.

For example, referring to fig. 11A, fig. 11A is a schematic view of an application scenario of a video editing processing method according to an embodiment of the present application, and in fig. 11A, a state 111 corresponding to each frame of a shot screen, including an edited state and an unedited state, is displayed in an upper right corner of the shot screen. When a user edits the shot picture in the editing state, first prompt information 112 is presented, and the first prompt information 112 includes an account number for editing the shot picture. When the user edits the shot picture in an unedited state, the user can directly respond to the editing operation.

For example, the first shot picture and the second shot picture satisfy at least one of the following association conditions: the first shot picture and the second shot picture are edited into the video editing script template by the same account; the first and second lens pictures belong to the same scene, for example, the first and second lens pictures are both scenes in a room.

In the embodiment of the application, the relevance of the shot pictures belonging to the same scene is higher, so that when a user edits a certain shot picture, the possibility of editing other shot pictures belonging to the same scene is higher, the shot pictures belonging to the same scene are locked in an exclusive mode, the optimization times of the shot pictures in the script can be reduced, and the editing resources can be saved. Similarly, the shot picture edited into the video editing script template by the same account number is also higher in association degree, so that the shot picture edited into the video editing script template by the same account number is locked in an exclusive mode, the optimization times of the shot picture can be reduced, and editing resources are saved.

As an example, prior to a video editing operation submitted in a video editing script template in response to at least one of the first account number and the second account number, may further include: inquiring the state of a first parameter, wherein the first parameter is a parameter corresponding to a third shot picture edited in the video editing script template by the video editing operation request; determining that a process responsive to a video editing operation is to be performed when both a first parameter and a second parameter related to the first parameter are in an unedited state; and when the first parameter and a second parameter related to the first parameter are both in an editing state, displaying second prompt information, wherein the second prompt information is used for prompting that the video editing operation cannot be immediately responded due to editing conflict.

For example, the first parameter may be any parameter in the video editing script template, or may be a parameter specified by the first account or the second account.

For example, the second prompt information is further used for prompting that the parameter corresponding to the third shot image is in an editing state; the second prompt message may further include an account number that is editing the parameter corresponding to the third shot.

For example, when the first parameter is updated from the edited state to the unedited state, it may be that the first parameter is edited completely or the first parameter is edited and canceled, and if the first parameter is edited completely, the editing result needs to be synchronously displayed in the video editing script template, and a prompt message capable of responding to the video editing operation is displayed; and if the first parameter editing is cancelled, cancelling the editing result in the video editing script template and displaying prompt information capable of responding to the video editing operation.

For example, referring to fig. 11B, fig. 11B is a schematic view of an application scenario of the video editing processing method provided in the embodiment of the present application, and in fig. 11B, the upper right corner of each column of parameters displays a state 113 corresponding to the parameter, including an edited state and an unedited state. When the user edits the parameter in the editing state, the second prompt message 114 is presented, and the second prompt message 114 includes the account number editing the parameter. When the user edits the parameter in the non-edited state, the user can directly respond to the editing operation.

For example, the first parameter and the second parameter satisfy at least one of the following associated conditions: the first parameter and the second parameter are edited into the video editing script template by the same account; the lens picture corresponding to the first parameter is the same as the lens picture corresponding to the second parameter; the first parameter is of the same type as the second parameter.

In the embodiment of the application, the association degree of the parameters edited into the video editing script template by the same account is higher, so that when a user edits a certain parameter, the possibility of editing the parameter edited into the video editing script template by the user is higher, the parameter edited into the video editing script template by the same account is locked in an exclusive mode, the optimization times of the parameters in the script can be reduced, and the editing resources can be saved. Similarly, the parameter association degree and the parameter association degree with the same type corresponding to the same shot picture are also higher, so that the parameter and the parameter with the same type corresponding to the same shot picture are locked in an exclusive mode, the optimization times of the parameters can be reduced, and the editing resources are saved.

In some embodiments, the video editing operations include a shot editing operation and a parameter editing operation; referring to fig. 5, fig. 5 is a schematic flowchart of a video editing processing method provided in an embodiment of the present application, and based on fig. 4, step S102 may include step S1021 to step S1022.

In step S1021, in response to the lens screen editing operation, a plurality of lens screens set by the lens screen editing operation are displayed in the video editing script template.

In some embodiments, in response to a lens screen editing operation for a lens screen editing region, a plurality of lens screens set by the lens screen editing operation are acquired through the lens screen editing region, and the plurality of lens screens set by the lens screen editing operation are displayed in the lens screen editing region.

As an example, the shot editing operation may be submitted by the first account or the second account. The display effect of the shot picture set in the video editing script template by different account numbers is different, for example, the border color of the shot picture set in the video editing script template by the first account number is different from the border color of the shot picture set in the video editing script template by the second account number.

For example, in fig. 9A, a user may edit a shot in the shot editing area 902, for example, the user may upload a picture or video as a shot directly in the shot editing area 902.

In step S1022, in response to the parameter editing operation, the parameters corresponding to the plurality of shot screens set by the parameter editing operation are displayed in the video editing script template.

In some embodiments, in response to a parameter editing operation for the parameter editing region, parameters of the plurality of lens screens set by the parameter editing operation are acquired through the parameter editing region, and the parameters of the plurality of lens screens set by the parameter editing operation are displayed in the parameter editing region.

As an example, the parameter editing operation may be submitted by the first account or the second account. The display effect of the parameters set in the video editing script template by different account numbers is different, for example, the font (or font size, font color) of the parameter set in the video editing script template by the first account number is different from the font (or font size, font color) of the parameter set in the video editing script template by the second account number.

For example, in fig. 9A, the user can edit parameters such as a shot number, a case, a duration, a transition, a scene, a sound effect, and music in the parameter editing area 903.

In some embodiments, parameter identification processing is performed on each shot picture to obtain parameters adaptive to a plurality of shot pictures, and the parameters adaptive to the plurality of shot pictures are used as default parameters and displayed in a video editing script template; in response to a parameter editing operation for a plurality of shot screens, replacing default parameters of the plurality of shot screens displayed on the video editing script template with parameters set by the parameter editing operation to replace the default parameters.

The following describes a procedure of performing parameter identification processing for each shot screen with reference to a plurality of examples.

As a first example, the following processing is performed for each shot screen: carrying out object recognition processing on the shot picture, and determining the recognized object as a file matched with the shot picture; wherein the types of objects include: scene, person, event.

For example, when the lens frame is a cyclist's frame, the text "bicycling" may be automatically populated in the case parameter. Therefore, by automatically filling the document parameters, a user does not need to fill and write a corresponding document in the video editing script template according to the shot picture, and the video editing efficiency is improved.

As a second example, one of the following processes is performed for each shot picture: carrying out object identification processing on the shot picture, and determining duration adapted to the shot picture according to the number of identified objects, wherein the number of the identified objects is positively correlated with the duration; and identifying the similarity between the shot picture and the adjacent shot picture, and determining the duration adapted to the shot picture according to the similarity, wherein the similarity and the duration are in negative correlation.

For example, the more the number of objects in the shot picture is, the more the information quantity representing the shot picture is, the more time the user spends understanding the shot picture is, so that the duration parameter positively correlated to the number of identified objects can be set, and the operation frequency of the user can be reduced while the video editing accuracy is ensured. Similarly, the higher the similarity between the shot picture and the adjacent shot picture is, the higher the association degree representing the two shot pictures is, and the less time is consumed for a user to understand the association between the two shot pictures, so that a duration parameter negatively related to the similarity can be set, and the operation times of the user can be reduced while the video editing accuracy is ensured.

As a third example, the following processing is performed for each shot screen: identifying historical parameters adaptive to the shot pictures as parameters adaptive to the shot pictures; wherein the type of the historical parameter comprises one of the following: historical parameters corresponding to historical lens pictures with highest similarity with the lens pictures; setting a history parameter with the highest frequency in the video editing process; and historical parameters set in the video editing process with the interval closest to the current time point. Therefore, by multiplexing the historical parameters, a user does not need to upload corresponding parameters in the video editing script template according to the shot picture, and the video editing efficiency is improved.

As a fourth example, the following processing is performed for each shot screen: carrying out object identification processing on the shot picture, and inquiring sound effects with a mapping relation between the shot picture and the identified objects in a mapping table, wherein the mapping table comprises a plurality of objects and a plurality of sound effects which are in one-to-one correspondence with the objects; and determining the sound effect having the mapping relation with the identified object as the sound effect matched with the lens picture.

For example, when the lens frame is a frame of a rider, it can be recognized that the object included in the lens frame is a "bicycle", so that a sound effect corresponding to the "bicycle", such as a "bicycle ring", can be queried in the local mapping table to serve as a sound effect parameter, and of course, a sound effect corresponding to the "bicycle" can also be directly queried in the network to serve as a sound effect parameter. And the sound effect parameters are automatically filled, so that a user does not need to upload corresponding sound effects in the video editing script template according to the shot picture, and the video editing efficiency is improved.

As a fifth example, the following processing is performed for each shot screen: identifying the similarity between the shot picture and the adjacent shot picture, and inquiring transition matched with the similarity; the transition matching the similarity is determined as a transition fitting the shot.

For example, the process of identifying the similarity between a shot and an adjacent shot may include: extracting first image features from a shot, extracting second image features from an adjacent shot, determining a geometric distance (e.g., a chebyshev distance, a euclidean distance, a minkowski distance, etc.) between the first image features and the second image features, and determining a similarity between the shot and the adjacent shot based on the geometric distance.

For example, when the similarity is smaller than a similarity threshold, the transition adapted to the shot picture is set as "hard cut", where the similarity threshold may be a default value or a value set by a user, a client, or a server; when the similarity is not less than the similarity threshold, the transition adaptive to the shot pictures is set to be 'push-pull' or 'overlapped', so that the transition between the shot picture with higher similarity and the adjacent shot pictures can be smooth and natural.

In step S103, in response to a video preview operation received in the video editing process, a preview video is generated based on at least one shot screen and parameters corresponding to the at least one shot screen.

In some embodiments, the client may invoke a corresponding service (e.g., a preview video generation service) of the terminal, and the process of generating the preview video is completed by the terminal. The client may also call a corresponding service (e.g., a preview video generation service) of the server, and the process of generating the preview video is completed through the server.

As an example, when the client calls the corresponding service of the server to complete the process of generating the preview video, the alternative step of step S103 may be: the client side responds to the video preview operation received in the video editing process and sends a video preview generation request to the server; the server responds to a preview video generation request, and generates a preview video based on at least one shot picture and parameters corresponding to the at least one shot picture; and sending the preview video to the client.

In the following, a process of generating a preview video by a terminal is described as an example, in which a client calls a corresponding service of the terminal. It should be noted that the process of generating the preview video by the client invoking the corresponding service of the server is similar to that described below, and will not be described again.

As an example, in fig. 7B, when a user triggers the video generation portal 703, a preview video 704 may be generated according to the content edited by the user in the video editing script template 702.

In some embodiments, a preview video may be generated based on all of the shots and corresponding parameters in the video editing script template; the preview video may also be generated based on portions of the take frames and corresponding parameters in the video editing script template.

As an example, in response to a shot screen selection operation, a preview video is generated based on the selected shot screen and the corresponding parameters. Therefore, the user can watch the preview video comprising the selected shot picture, so that the personalized requirements of the user are met, and the resources consumed by generating the preview video are saved.

Here, the parameters include a clipping parameter and an engagement parameter; the clipping parameters include at least one of: case, duration, sound effect; the engagement parameters include at least one of: shot number, transition.

In some embodiments, referring to fig. 6, fig. 6 is a schematic flowchart of a video editing processing method provided in an embodiment of the present application, and based on fig. 4, step S103 may include steps S1031 to S1033.

In step S1031, in response to a video preview operation received in the video editing process, the following processing is performed for each of the shot screens: and according to the clipping parameters of the shot pictures, clipping the shot pictures to obtain shot fragments corresponding to the shot pictures.

In some embodiments, the following processing is performed for each shot picture: editing the shot picture into a preprocessing segment, wherein the playing time length of the preprocessing segment is the time length in the editing parameters of the shot picture; and adding the file in the clipping parameters of the shot picture into the preprocessing section, and adding the sound effect in the clipping parameters into the preprocessing section to obtain the shot section corresponding to the shot picture.

For example, a shot picture is firstly clipped into a preprocessing segment, then a pattern in the clipping parameters is overlapped in the preprocessing segment in a floating layer mode, and finally the sound effect in the clipping parameters is called to fill the preprocessing segment, so that the shot segment corresponding to the shot picture is obtained.

In step S1032, when the number of at least one lens screen is one, a lens segment of the corresponding lens screen is determined as the preview video.

In some embodiments, when the preview video is generated based on one shot picture and corresponding parameters, since one shot picture only corresponds to one shot section and one shot section does not need to be spliced, the linking parameters of the shot picture do not need to be considered, and the corresponding preview video can be generated only according to the clipping parameters corresponding to the shot picture.

In step S1033, when the number of the at least one shot image is multiple, the shot segments corresponding to each shot image are combined according to the connection parameter of each shot image, so as to obtain the preview video.

In some embodiments, when the number of the at least one shot picture is multiple, the multiple shot slices are sequenced according to the sequence of the shot sequence numbers in the linking parameters to obtain a shot slice sequence; sequentially performing the following connection processing for each shot in the shot sequence: connecting the shot segments with adjacent shot segments according to transitions in the corresponding connection parameters of the shot segments; and taking the shot section sequence after the connection processing as a preview video.

As an example, the splicing manner between the shots is based on the transitions in the splicing parameters, for example, when the transitions in the splicing parameters are overlapped for N seconds, the shot can be extended for N seconds, and the transparency of the shot is gradually reduced from 100 to 0 during the time, and the transparency of the next adjacent shot is gradually increased from 0 to 100, so as to achieve the smooth process exhibition between the shots.

In step S104, the preview video is displayed.

In some embodiments, displaying the preview video may be displaying the preview video with a display box integrated into the document editing interface; it is also possible that the video editing program calls the player program pop-up window to display the preview video, or the video editing program calls the player program to display the preview video in the window of the video editing program itself.

In some embodiments, after step S104, the preview video (i.e., the exported video file) may also be downloaded in response to the video editing completion operation, so that the user may save the generated video after previewing the video.

By way of example, in fig. 7B, a preview video 704 is displayed and a video download entry 705 is included in the document editing interface, and when the user triggers the video download entry 705, the preview video 704 can be downloaded.

In the embodiment of the application, the shot pictures and the corresponding parameters in the video editing script template can be accurately and efficiently identified and preview videos can be generated on a document editing interface, so that a user can visually know the content logic of the videos, the technical problem that the video editing cost is high due to the fact that the rhythm of the videos cannot be confirmed by static shot scripts and the videos need to be generated again after the parameters are modified every time in the related technology can be solved, the optimization times of the shot pictures and the corresponding parameters can be reduced, editing resources can be saved, and the editing efficiency of the videos is improved.

In some embodiments, after step S104, the method may further include: responding to a modification operation aiming at the preview video, and displaying a video modification page, wherein the video modification page comprises at least one shot picture and a parameter corresponding to each shot picture; and responding to the parameter modification operation received in the video modification page, and updating the displayed preview video according to the modified parameters.

As an example, referring to fig. 12, fig. 12 is an application scene schematic diagram of a video editing processing method provided in an embodiment of the present application, in fig. 12, when a user clicks a certain frame of shot screen in a preview video 121, a floating window displays a video modification page 122 corresponding to the clicked shot screen, the user may modify parameters corresponding to the shot screen in the video modification page 122, and after the user finishes modifying, the preview video 121 may be updated by triggering a determination button 123, so that the human-computer interaction efficiency may be improved in the modification process of the preview video.

In some embodiments, after step S101, the method may further include: responding to a collaboration editing triggering operation received in a document editing interface, and displaying a collaboration account setting page of a first account; the first account is an account for logging in a document editing interface, and the collaboration account setting page comprises at least one candidate account; and in response to the account selection operation received on the collaborative account setting page, determining the selected at least one candidate account as a second account for editing the video editing script template in cooperation with the first account, and sending the video editing script template to the second account.

As an example, an editing right setting entry is displayed on a collaboration account setting page; and responding to the authority setting operation aiming at the editing authority setting entry, and acquiring the set authority, wherein the type of the authority comprises: viewing authority and editing authority; determining that processing of the video editing script template that sends the application authority to the second account is to be performed.

For example, for an account with viewing authority, the update of the video editing script template can be viewed in real time; for the account with the editing authority, the updating of the video editing script template can be checked in real time, and the video editing script template can be edited.

For example, the same authority may be globally set for all shots and parameters in the video editing script template, for example, the second account may view and edit all shots and parameters in the video editing script template; different permissions can also be set for each shot picture and parameter or each type of shot picture and parameter in the video editing script template, for example, the second account can view the update of the parameter 1 in real time and edit the parameter 1, but can only view the update of the parameter 2 in real time and cannot edit the parameter 2.

For example, in addition to the manner of manual allocation through the first account, the permission of the video editing script template may be automatically allocated through the client, for example, corresponding permission may be automatically allocated according to a role of the second account, where the role of the second account may be set by the first account or the second account, or corresponding permission may be automatically allocated according to an activity level of the second account, where the activity level of the second account is positively correlated with the number of times the second account participates in editing, and the activity level of the second account is positively correlated with the number of times the second account interacts based on editing.

For example, referring to fig. 13, fig. 13 is a schematic view of an application scenario of a video editing processing method provided in this embodiment of the application, in fig. 13, when a user triggers a collaboration entry 131, a collaboration account setting page 132 is displayed, the user can select an account to be sent in the collaboration account setting page 132 and set a right of a video editing script template in an editing right setting entry 133, and after the user selects the right and the account to be sent, the video editing script template to which the right is applied can be sent to the selected account.

The embodiment of the application provides a multi-user cooperation function for the video editing script template, can solve the technical problems of high editing cost and low editing efficiency caused by the fact that multi-user cooperation cannot be implemented for static shot-splitting scripts in the related art, can improve the communication efficiency in the video editing process, and reduces the optimization times of shot pictures and corresponding parameters, thereby saving editing resources.

The following describes a video editing processing method provided in an embodiment of the present application, taking an online document as an example.

According to the embodiment of the application, the video can be quickly generated through the text editing of the shot script, for example, after a video planner fills in and selects the structured text (namely the parameters) of the corresponding shot painting, the system can automatically recognize and generate the preview video, so that the video production efficiency is improved. In addition, the embodiment of the application also utilizes the characteristic that the online document can be modified in real time in a multi-person cooperation manner, so that the communication efficiency is improved, the information structure of the composition of the story board shot script is processed, the preview video is directly generated, the imagination of a user is not needed, and the video generation efficiency is further improved on the basis of not changing the industry process and the user habit.

Referring to fig. 7A, 7B and 8, fig. 7A and 7B are schematic application scenarios of a video editing processing method provided in an embodiment of the present application, and fig. 8 is a schematic flow diagram of the video editing processing method provided in the embodiment of the present application. Next, a specific implementation of the embodiment of the present application will be described with reference to fig. 7A, 7B, and 8.

In step S801, the terminal displays a video editing script template in response to a video editing trigger operation received in the online document.

In some embodiments, in FIG. 7A, when a user clicks on the video editing script entry 701 in the online document, a video editing script template 702 as shown in FIG. 7B may be created and displayed in the human-computer interaction machine interface.

In step S802, the terminal displays a plurality of shot screens and parameters corresponding to each shot screen in the video editing script template in response to a video editing operation.

In some embodiments, in fig. 7B, the user may fill in (or upload) a plurality of shots and parameters (including shot number, file, duration, transition, sound effect, music, and motion inside the shot) corresponding to each shot in the video editing script template 702. The editing of the lens picture can copy and paste or upload pictures or videos, if a plurality of pictures exist, the pictures or videos are arranged in sequence, and the video needs to fill in the use time period in the uploading stage. Shot number editing is typically a default fill. Corresponding characters can be directly edited in the document editing process, whether the document is used as a subtitle or a voice-over can be selected, and if not, the document is not displayed by default. Duration edit, i.e. indicating the length of stay of the line (the shot), where the user can fill in "number + seconds(s)", otherwise show 1s by default. Transition editing, namely indicating the connection relationship between the shot picture and the next shot picture, can select (options include hard cutting, push-pull, folding and the like) and needs to input the duration, otherwise, the default is direct hard cutting. In the sound effect editing, a user is supported to upload an audio file in an mp3 format or input text (such as 'clock sound'), and the server can perform network search downloading according to the input text to obtain corresponding sound effects, wherein the use duration of the sound effects depends on the duration of a lens picture. The music editing supports users to upload audio files in mp3 format and fill in the use period in the uploading stage as full-film use. The specific data editing method is determined by the actual scene, and is not limited here.

In some embodiments, the content in the video editing script template may be edited by the account (i.e., the first account mentioned above) that logs into the online document, or may be edited by the collaboration account (i.e., the second account mentioned above).

In step S803, the terminal transmits the plurality of shot screens and the parameters corresponding to each shot screen to the server, and the server generates a preview video from the plurality of shot screens and the parameters corresponding to each shot screen and transmits the preview video to the terminal.

In some embodiments, the process of generating the preview video may include: firstly, generating the shot segments of each shot image according to the shot sequence number respectively, then combining all the shot segments to generate a complete preview video, wherein the duration of the preview video is X seconds, calling a 'music' parameter in a document, and starting to play the whole video according to the shot sequence number of a line where the 'music' parameter is located, wherein the playing duration of the music is X seconds.

As an example, the process of generating a shot segment for each shot may include: for the video part, the "shot" in the document may be called first, for example, the pictures or videos in the "shot" are compressed or enlarged proportionally according to the 1080 × 720 bit specification, so as to ensure the adaptation of no cropping, wherein the duration of the stay of the pictures calls the "duration" parameter M seconds in the document. Then judging whether there is any file and whether there is any checking caption, if there is file and checking caption, calling the text information in the file, and superposing the file on the picture by 32-bit white Song body and black background bar based on the total word number length. For the audio part, the "sound effect" parameter in the document can be called first to fill (if the content is empty, the sound is absent), and the playing time is M seconds; and then, according To whether the check voice exists in the 'case' parameter, if so, calling the Text information and converting the Text information into voice information through a Text To Speech (TTS) technology, if the voice playing time is not more than M seconds (namely the 'time length' parameter in the document), not processing the voice information, and if the voice playing time is more than M seconds, accelerating the voice playing of the voice.

As an example, the manner of joining between shots is based on the "transition" parameter in the document, for example, when the "transition" parameter of a shot is overlapped for N seconds, the shot is extended for N seconds, and the transparency of the shot is gradually reduced from 100 to 0 in the period of time, and the transparency of the next shot is gradually increased from 0 to 100, so as to achieve smooth process exhibition. If the 'transition' parameter is empty content, the processing is not carried out, and the hard cutting is directly carried out.

In step S804, in response to the video preview operation, a preview video is displayed.

In some embodiments, in fig. 7B, when the user triggers the video generation portal 703, the server may generate a preview video 704 according to the content the user fills in the video editing script template 702, wherein the size of the preview video 704 may default to 1080 × 720, and the material of each shot is not cropped in adaptation, and the user may modify the content in the video editing script template 702 according to the preview video 704. Also, when the user triggers the video download portal 705, the preview video 704 may be downloaded.

According to the embodiment of the application, the video can be quickly generated through the literal editing of the shot script, the cost of generating the video can be reduced through multi-person cooperation and real-time modification, and the video generation efficiency is improved.

An exemplary structure of a video editing processing apparatus provided in an embodiment of the present application, which is implemented as a software module, is described below with reference to fig. 3.

In some embodiments, as shown in fig. 3, the software modules stored in the video editing processing device 455 of the memory 450 may include: a display module 4551 configured to display a video editing script template in the document editing interface; an editing module 4552 configured to display a plurality of set shot screens and parameters corresponding to each shot screen in the video editing script template in response to a video editing operation; a generating module 4553, configured to generate a preview video based on at least one shot screen and parameters corresponding to the at least one shot screen in response to a video preview operation received in a video editing process; the display module 4551 is further configured to display the preview video.
