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.
