Problems solved by technology

[0003] At present, some video editing software can perform non-linear editing on the source video file, and can search the video according to user instructions until the split point is found, and divide the video into multiple video clips, and then combine the video clips to be watched into one Play a new video file, this operation is very fast, but there may be a time difference between the audio and video in the new video file, or some video frame data is incomplete and cannot be played, etc.

Embodiment 1

[0074] Embodiment one, see figure 2 , the process of video editing in this embodiment includes:

[0075] Step 201: Cutting the source video file to obtain two first video files to be merged.

[0076] The cutting point time in the cutting instruction is 8:00:00 and 8:10:00 respectively, corresponding to the cutting instruction, the first segment of the first video file is obtained. The cutting point time in the cutting instruction is 8:20:00 and 8:30:00 respectively, corresponding to the cutting instruction, the second segment of the first video file is obtained. Specifically, according to the video time stamp corresponding to the video stream and the audio time stamp corresponding to the audio stream in the source video file, the video data frame and the audio data frame corresponding to the cut-off time can be obtained to obtain the first video file.

[0077] Step 202: Determine whether the end position of each segment of the first video file lacks an audio data frame? If...

Embodiment 2

[0085] Embodiment two, see image 3 , the process of video editing in this embodiment includes:

[0086] Step 301: cutting the source video file to obtain three first video files to be merged.

[0087] The cutting point time in the cutting instruction is 8:00:00 and 8:10:00 respectively, corresponding to the cutting instruction, the first segment of the first video file is obtained. The cutting point time in the cutting instruction is 8:20:00 and 8:30:00 respectively, corresponding to the cutting instruction, the second segment of the first video file is obtained. The cutting point times in the cutting instruction are 8:45:00 and 8:55:00 respectively, corresponding to the cutting instruction, the third segment of the first video file is obtained.

[0088] Specifically, according to the video time stamp corresponding to the video stream and the audio time stamp corresponding to the audio stream in the source video file, the video data frame and the audio data frame correspond...

Abstract

The invention discloses a video cutting method and a video cutting device, which are used for improving playing quality of video files subjected to cutting. The method comprises the following steps of segmenting a source video file toacquireat least two segments of to-be-merged first video files; performing audio data frame checking for an ending position of each segment of the first video file, and when the ending position of the first video file is lack of the audio data frame, performing audio interpolation for the first video file toacquirecorresponding processed first video file; and merging each segment of the first video file to form a to-be-played target video file. Thus, the segmented first video files are adjusted according to the audio data frame, and the adjusted first video files are merged, consequently, when the merged target video file is played, time difference between audio and video is avoided, and playing quality of the cut video file is improved.

Description

technical field [0001] The invention relates to the field of multimedia technology, in particular to a method and device for video clipping. Background technique [0002] With the development of multimedia technology, the playback of video, audio, pictures, etc. has been widely known by users. When performing multimedia playback, such as video playback, the user may not need to watch the entire video content, or may only want to watch some of the clips. In this way, the video needs to be edited, and several fragment files are cut from the source video file according to requirements, and then merged into a new video file for playback. [0003] At present, some video editing software can perform non-linear editing on the source video file, and can search the video according to user instructions until the split point is found, and divide the video into multiple video clips, and then merge the video clips to be watched into one Playing a new video file is very fast, but there ...
