The ghost cartoon video (i.e. the repeat video of the cartoon segments) is synthesized by a plurality of video segments and background music, the plurality of video segments are switched according to the drum points (the accent points) in the background music, so that the video is changed to have a rhythmic feeling, and a certain video segment or a plurality of video segments can be played repeatedly in different video segments, thereby achieving the effect of an interesting video. The method comprises the steps of selecting background music for making the ghost image videos, recording time points of all drum points in the background music, cutting a plurality of video segments according to the time points of all the drum points, determining the repeatedly played videos, and calculating the time length and the times of the repeatedly played parts. The video production method provided by the embodiment of the application can be used for producing the Kadian ghost video only by selecting the background music and the multiple sections of videos by the user, and can be applied to various application programs with video production, such as a live broadcast application program, a short video application program and a video editing program. The embodiments of the present application take short video applications as examples, and the detailed description of the schemes is given, and other cases are similar and will not be repeated.
Fig. 1 is a flowchart of video production according to an embodiment of the present disclosure. Referring to fig. 1, the embodiment includes:
The plurality of video segments may be videos stored in a user terminal, the background audio may be background music selected in a network, the accent time points included in the background audio may be recorded in an accent time point file, the time points corresponding to each accent point of the background audio, that is, the accent time points, are recorded in the accent time file, the accent points may be drum points in the background music, and generally, intervals between adjacent accent time points in the background music are the same.
In practice, a user may produce a ghost video at a short video application. The user can select the background music required by making the Kappan ghost video on a background music selection interface in the short video application program, a recommendation list and a search box are arranged in the background music selection interface, and the user can select the background music recommended by the short video application program from the recommendation list and can also select the background music which the user wants to use in the search box. When the user finishes selecting the background music, the terminal can send a corresponding acquisition request to the server, and the server can send the audio frequency of the background music selected by the user and the accent time file corresponding to the background music to the terminal according to the acquisition request. Then, the user can enter a video selection interface, a plurality of preview windows are displayed on the video selection interface, the video cover stored in the local area is displayed in the preview windows, and the user can click the selected option set in the preview windows to select the video materials required by the user for making the click videos. In addition, the terminal may prompt the duration of the video segment selected by the user according to each adjacent accent point time interval in the accent time point file corresponding to the background music selected by the user, that is, the video duration of the video segment selected by the user may be greater than each adjacent accent point time interval in the accent time point file. For example, if the interval between adjacent stress points in the stress point file is 6 seconds, the user can select a video segment stored in the terminal for more than 6 seconds.
And 102, selecting a target video segment which needs to be subjected to segment repeated processing from a plurality of video segments.
The segment repeat processing is to select one or more segments of video segments from the video segments, repeat playing the video segments, and then splicing the video segments into the original video segments.
In implementation, after the user selects a video, the user may enter a video production page, a plurality of video segments selected by the user are displayed in the video production page, and the user may select a target video segment that needs to be subjected to segment repetition processing again from the selected plurality of video segments, where the user may select one of the video segments or select a plurality of the video segments as the target video segment that needs to be subjected to segment repetition processing.
And 103, determining a segment repeated video band in the target video band, and modifying the target video band into a stuck segment repeated video band based on the segment repeated video band.
And the duration of the click segment repeated video segment is equal to the accent time interval of the background audio.
In implementation, according to an accent time point file corresponding to background music, an accent time interval of background audio, that is, a time interval of each adjacent accent point in the accent point file, is obtained, then a section of video can be determined in a target video section, then the section of video is repeatedly circulated to obtain ghost video sections (that is, a section repeated video section), and then the ghost video sections are cut and spliced according to the section repeated video section and the target video section to generate a stuck ghost video section.
Alternatively, a segment repeat video segment can be determined in the target video segment based on the accent time interval of the background audio.
In implementation, the duration of the ghost video segment may be determined according to the time interval of the accent of the background audio, for example, the duration of the ghost video segment may be one half of the time interval of the accent of the background audio, a video segment with a duration of one sixth of the time interval of the accent may be captured from the target video segment, and then the video segment is played circularly 3 times to obtain the ghost video segment, where the duration of the ghost video segment is one half of the time interval of the accent of the background audio.
Optionally, when the segment repeat video band is determined in the target video segment, a part with a period of time as the duration of the stress time interval may be selected from the target video segment to obtain a stuck video segment; determining the duration of a basic video clip based on the accent time interval of the background audio; determining a part with the time length before the tail end of the click video segment as the time length of the basic video as a basic video segment; and circulating the basic video clip for preset times to obtain the clip repetition frequency band.
The duration of the basic video clip can be set by a technician and can be determined according to the duration of the accent time interval of the background audio.
In an implementation, before determining the ghost video segment, the stuck video segment may be determined based on an emphasis time interval of the background audio. Wherein the duration of the click video segment is equal to the accent time interval of the background audio. Then, a base video clip is determined among the stuck video clips. As shown in fig. 2, the terminal may automatically select a portion having a duration of the interval between the background audio accent time points after the start of the target video segment as the stuck video segment. In addition, a user can select a click video segment from the target video segment, and after the user selects the target video segment, the user can enter a video production page, a progress bar of the target video segment is set in the video production page, and each video frame of the target video segment is displayed in the progress bar of the target video segment, as shown in fig. 3, the user can drag the progress bar to select the click video segment, and the duration of the click video segment selected by the user is equal to the interval duration of the background audio accent time points. For example, the time interval of the accent points is 4 seconds, the target video segment is 6 seconds, and the user can drag the progress bar to select a continuous video segment with a duration of 4 seconds from the target video segment. After the terminal determines the card video segment, the video segment with the time length before the tail end of the card video segment as the time length of the basic video segment can be intercepted and used as the basic video segment, and then the basic video segment is circulated for preset times to obtain the ghost video segment, namely the ghost video segment comprises the basic video segment with preset times.
When the duration of the basic video segment is determined according to the accent time interval of the background audio, the corresponding processing may be as follows: and determining the time length of the basic video clip as the product of the accent time interval of the background audio and a preset proportion value.
In an implementation, a value obtained by multiplying the accent time interval of the background audio by a preset ratio value may be determined as the base video segment duration. The preset ratio value may be preset by a technician. For example, if the preset ratio value is set to 0.2, the duration of the base video segment is one fifth of the duration of the accent time interval of the background audio, that is, one fifth of the duration of the stuck video segment.
Optionally, after the ghost video segment is determined, the target video segment may be modified into the stuck ghost video segment according to the ghost video segment, and the corresponding processing is as follows: deleting the part with the duration being the duration of the segment repeat video band at the front end of the stuck video band, and splicing the segment repeat video band at the tail end of the stuck video band to obtain the stuck segment repeat video band.
In implementation, after obtaining the ghost video segment based on the base video segment, the front end of the card point video segment may be deleted for a part of the ghost video segment, and the ghost video segment may be spliced at the end of the card point video segment to obtain the card point ghost video segment. In general, in background music, a soft sound point (weak drum point) is present at an intermediate time point between two hard sound points, so that the time for starting ghost is selected to be the time point at which the soft sound point appears, thereby increasing the rhythm of the ghost effect. As shown in fig. 4, the duration of the base video segment may be one sixth of the duration of the accent time interval of the background audio, the preset number of times may be 3, and the ghost video segment is obtained after the base video segment is cycled for 3 times, where the duration of the ghost video segment is one half of the duration of the accent time interval. And deleting the part of the video with the duration being one half of the duration of the accent time interval from the front end of the clamped video segment, and then clamping the tail end of the clamped video segment of the ghost video segment, wherein the time point of the obtained clamped ghost video segment for starting playing the segment repeated video segment is the middle time point of the clamped ghost video segment.
In addition, before the ghost video segment is spliced at the tail end of the card point video segment, special effect processing can be performed on the ghost video, and the corresponding processing can be as follows: carrying out special effect processing on the repeated video segments of the segments; deleting the part of which the time length is the time length of the segment repeated video segment at the front end of the stuck point video segment, and splicing the segment repeated video segment after the special effect processing at the tail end of the stuck point video segment to obtain the stuck point segment repeated video segment.
In implementation, the obtained ghost video segment may be subjected to special effect processing, for example, a filter special effect is added to the ghost video segment, and a video frame of the ghost video segment is enlarged. In addition, different special effect processing can be performed on each basic video segment in the ghost video segment, for example, different filter special effects are added to each basic video segment, the amplification ratio of the video frame in each basic video segment is different, and the like. After the ghost video segment is subjected to special effect processing, the front end of the ghost video segment with the duration being the duration of the ghost video segment can be deleted, and the ghost video segment subjected to special effect processing is spliced at the tail end of the ghost video segment to obtain the ghost video segment with the duration being the duration of the ghost video segment.
And 104, generating a composite video based on the segment repeated video segment, the video segments of the plurality of video segments except the target video segment, the background audio and the accent time points included by the background audio.
In implementation, after the ghost video segment corresponding to the target video segment is generated, the user can preview the generated ghost video segment, and when the ghost video segment is previewed, the terminal interface also displays options of confirmation and non-confirmation, and when the option of non-confirmation selected by the user, the method can return to the step 103 to reselect the ghost video segment, and then the ghost video segment is created again, or return to the step 102 to reselect the target video segment needing ghost processing. When the user selects the confirmed option, the terminal can cut the video segments of the plurality of video segments except the target video segment into the click videos corresponding to the plurality of video segments according to the accent time points included in the background audio. Generally, the time lengths of a plurality of video segments selected by a user are different, and the terminal can cut the video selected by the user according to the time of each accent point recorded in the accent point file, so that the time length of each video segment is the same as the interval time length of adjacent accent points in the background music selected by the user. As shown in fig. 5, if the interval duration of adjacent accent points in the background audio selected by the user is 3 seconds, and the duration of the video selected by the user is 5 seconds, 4 seconds, 6 seconds, 7 seconds, etc., then the video selected by the user can be uniformly cut into video segments with a duration of 3 seconds. In addition, when the video is cut, a video segment three seconds before the start of the video, a video segment 3 seconds after the start of the video, or a video segment 3 seconds in the middle of the video may be cut, and a position where the video is cut may be preset by a technician, which is not limited herein. After the stuck video segments corresponding to the plurality of video segments are cut, the ghost video segments and the stuck video segments can be spliced into a video segment, and then the spliced video is synthesized with the background music selected by the user to generate the ghost stuck video.
According to the method and the device, the ghost image video segments are determined through the accent time interval of the background audio (namely the ghost image segments are repeated), the multiple video segments are cut, finally the multiple video segments and the ghost image video segments are spliced and synthesized with the background music, and ghost image videos are generated. Therefore, the method and the device do not need a user to manually intercept the video and repeatedly process the video, and can effectively improve the efficiency of the user in making the ghost livestock video.
