The technical solution of the embodiment of the present disclosure is explained in detail below:
with the development of the internet, video editing is more and more widely applied in life. In the existing video generation method, a plurality of video files or pictures can be directly selected, and the video files or pictures are spliced into one video file according to a preset sequence or a random sequence. In this way, the duration of the spliced video file is the sum of the duration of the video file and the duration of the picture, where the duration of the picture may be set to a fixed duration, for example, 3 seconds or 4 seconds. If more pictures and video files are selected, the duration of the spliced video is longer, and the effect is single. In addition, it is relatively inefficient to stitch different types of video files together, for example, a video file containing a person and a video file containing an animal, or other video files with relatively high contrast.
Of course, the user may also edit a single video file and then splice a plurality of edited video files. However, for each video file, the preview needs to be played repeatedly, then the effects of cutting, intercepting, adding filters, music, transition and the like are repeatedly performed on each video file, and the videos of different types need to be deleted and reduced, and the videos of the same type need to be screened from the material, so that the videos which are considered by the user to have better effects can be spliced. Therefore, a large amount of manual editing operation is required in the process, the editing cost is increased, the efficiency is low, and the splicing effect is poor for unprofessional users.
In order to solve the above problems, the present disclosure provides a video generation method, a video generation apparatus, an electronic device, and a computer-readable storage medium, which can improve the efficiency of video generation and the effect of generating a video.
Referring to fig. 3, fig. 3 shows a flowchart of a video generation method in an embodiment of the present disclosure, which may include the following steps:
step S310, acquiring a plurality of target media files, and determining media categories of the plurality of target media files.
Step S320, selecting a plurality of media files to be edited from the plurality of target media files according to the media categories of the plurality of target media files.
Step S330, automatically splicing and generating a video file based on a plurality of media files to be edited.
According to the video generation method, the plurality of media files to be edited can be selected from the target media files according to the media types of the target media files and automatically spliced to generate the video files, and users do not need to edit and process the video files, so that the video generation efficiency can be improved. In addition, even if the generated video file does not meet the requirements of the user, the user can do a little processing based on the video file, so that the processing cost can be reduced, and the video generation efficiency and the generated video effect can be improved.
The video generation method according to the embodiment of the present disclosure is described in more detail below.
In step S310, a plurality of target media files are acquired, and media categories of the plurality of target media files are determined.
In an embodiment of the present disclosure, a media file includes: the target media file refers to a media file selected from media files stored in the terminal device, and may be, for example, a media file stored in the terminal device on the last day, two days, a week, and the like. The method and the device can edit a plurality of video files to generate new video files, can also edit the video files and pictures to generate new video files, and can also edit a plurality of pictures to generate video files.
The media category of the target media file refers to a category to which the target media file belongs, and for example, the category may include: different people, food, flowers, sports, tourism, etc. Video files and picture files of the same person can be classified into one category, video files and picture files containing food can be classified into one category, and the like.
For the media files (all media files or media files under the designated path) stored in the terminal device, the mapping relationship between the media files and the media categories can be established in advance. Specifically, each media file stored in the terminal device may be scanned, the media category of a single media file or a media segment in a single media file may be determined, and a mapping relationship between the media file or the media segment in the media file and the media category may be established. Thus, when searching for media files, the user can also search by media category.
When a single media file is an image, the image category of the image may be directly taken as the media category of the media file. And the video is composed of a video frame sequence, so that the media category corresponding to the video can be determined by the image category corresponding to the video frame sequence. In one implementation manner of the present disclosure, when a single media file is a video, a method for determining a corresponding media category may be as shown in fig. 4, and may include the following steps:
step S410, extracting a plurality of key frames in the video, and determining an image category of each key frame.
In the embodiment of the disclosure, each key frame may be processed based on a deep learning algorithm, and information such as a person, an object, a scene, a behavior, and the like in the key frame is identified, so as to determine an image category of each key frame. For example, the image categories may be people, animals, food, landscapes, and so on.
Step S420, determining the media category of the media file based on the image categories of the plurality of key frames; alternatively, the media category of the media segment in the media file is determined.
It should be noted that, for some video files, the image categories of multiple key frames are the same category, and then the video category of the entire video file can be determined as the category. For other video files, a certain segment in the video file is in one category, and other segments are in other categories, at this time, different video segments in the video file can be respectively marked as different video categories, and of course, the corresponding start time and end time of the video segment of each video category in the video file can also be recorded.
It is worth mentioning that when the user takes a video or a photo, the camera can recognize the face in real time, so that the related face information can be recorded during the taking, and the related face information can also be recorded during the storing of the video or the photo. During scanning, the face information can be directly classified, so that the classification efficiency can be improved.
In the embodiment of the present disclosure, after classifying the media files, if the user is not satisfied with the classification result, or the user wants to perform special processing on a certain media file. For example, a video file whose media category is a person is classified into a landscape category, and the user may adjust the media category of the video file. In response to a media category adjustment operation for any media file, a media category corresponding to the media file may be adjusted from a first media category to a second media category. Optionally, the media category adjusting operation may be: remove the media file from the first media category and reclassify the media file into a second media category, and so on. Therefore, the classification result after adjustment can better meet the requirements of users.
It should be noted that, since the media file in the terminal device may be updated continuously, the video generation process of the embodiment of the present disclosure may also be periodic, for example, a new video file may be generated from the updated media file in the terminal device every day or every two days. Therefore, the plurality of target media files acquired in this step may be media files of the day before the current time, or media files of the two days before, and the like, and may be specifically set according to a period of video generation. Therefore, the media files processed before can not be processed repeatedly in the next processing so as to avoid wasting resources.
In step S320, a plurality of media files to be edited are selected from the plurality of target media files according to the media categories of the plurality of target media files.
In the embodiment of the present disclosure, after the media categories of the multiple target media files are determined, the target media files may be spliced according to the media categories, that is, the media files with the same media category may be spliced, so that the target media files with the same media category may be selected from the multiple target media files and used as the multiple media files to be edited. For example, when a plurality of target media files contain the same character, the target media file of the same character may be selected from the plurality of target media files as a video file to be edited.
In step S330, a video file is automatically generated by splicing based on a plurality of media files to be edited.
In the embodiment of the present disclosure, for a plurality of selected media files to be edited, each media file to be edited may be that the entire media file corresponds to a certain media category, or that one or more media segments in the media file correspond to a certain media category. Therefore, when video splicing is performed, for a single media file to be edited, media segments may be extracted from the media file to be edited first, where media categories of the media segments extracted from multiple media files to be edited are the same. And then automatically splicing a plurality of media segments extracted from a plurality of media files to be edited to generate a video file. Of course, a single media file to be edited and media segments extracted from other media files to be edited may also be automatically spliced to generate a video file. Therefore, the media segments in the media files are used as the splicing materials, and the whole media files are not directly used as the splicing materials, so that the video files which have long video time and contain contents which are not needed by users can be prevented from being generated, and the splicing effect of the video files is improved.
Since the video splicing process is automatically completed without manual operation of a user, the video file can be displayed to the user after the video file is generated. The user may save the video file if satisfied with it. The user may also modify the video file if the user is not satisfied with the video file. Specifically, in response to an editing operation for a video file, the video file is processed to obtain a processed video file. In general, when a user modifies a video file, a simple editing operation can be performed to obtain a video file that the user is satisfied with, so that the video generation efficiency can be improved.
In another implementation manner of the present disclosure, for a plurality of selected media files to be edited, before automatically splicing and generating a video file, a user may also edit the plurality of media files to be edited to generate a target video file that better meets the user requirements. Specifically, in response to an editing operation for a plurality of media files to be edited, the plurality of media files to be edited are edited to obtain edited media files; and responding to the splicing operation of the edited media file to generate a target video file. Although user operations are increased compared with the method for automatically generating the video file, the user can generate the target video file which meets the requirements of the user by performing simple editing operations on the basis of a plurality of media files to be edited, so that the video generation efficiency and the effect of generating the target video file are improved.
In another scenario, the present disclosure may also support a user manually selecting a media file to generate a video file. Specifically, in response to a media file selection operation, a to-be-processed media file selected by a user is acquired, and other media files with the same media type as that of the to-be-processed media file are displayed to the user, so that the user edits according to the other media files. That is, other media files with the same media category may be recommended to the user according to the media file selected by the user. The user can select more media files from other media files for editing according to the own requirements, so that the user can select the desired media files more quickly, and further, the video generation efficiency and the video file generation effect can be improved.
In the video generation method according to the embodiment of the present disclosure, media files or media segments in the media files are classified into predetermined media categories (for example, the same person may be classified into the same media category, different persons may be classified into different media categories, etc.) through automatic scanning or user setting, and the media files or the media segments in the media files are used as materials for subsequently generating video files. When editing, the video file with better effect can be generated according to the media files and the media segments by automatic splicing, and the user does not need to edit, thereby improving the efficiency and the effect of video generation. The user can edit the generated video file to generate a video file with better effect.
It should be noted that although the various steps of the methods of the present disclosure are depicted in the drawings in a particular order, this does not require or imply that these steps must be performed in this particular order, or that all of the depicted steps must be performed, to achieve desirable results. Additionally or alternatively, certain steps may be omitted, multiple steps combined into one step execution, and/or one step broken down into multiple step executions, etc.
Further, in the present exemplary embodiment, there is also provided a video generating apparatus 500, as shown in fig. 5, including:
