Method for recording and editing long video through mobile terminal

Abstract

The present invention discloses a method for recording and editing a long video through a mobile terminal, comprising the steps of recording a first video and performing encoding processing on the first video; saving the last picture of the first video and generating transition animation; recording a second video and performing encoding processing on the second video; combining the first video, the transition animation, and the second video to obtain a third video, and performing picture rendering processing on the third video to obtain a recorded and edited long video. By adoption of the scheme provided by the invention, not only can videos be recorded and accessed quickly, but also the animation can be generated based on animation real-time checking calculation, thereby saving resource space and also making the animation smoother.

Description

technical field [0001] The invention relates to the field of video processing, in particular to a method for recording and editing long videos through a mobile terminal. Background technique [0002] At present, mobile phone video editing is mostly in the form of short videos, basically within 30 seconds, so the amount of video data will not be large, and intra-frame compression such as mjpeg can be used to achieve fast random access, but if you want to record for 5 minutes For the above 720P video, the amount of data will reach the GB level, and the high-resolution mjpeg codec will waste a lot of performance, and it cannot be processed in real time on a low-performance machine. And most of the video stickers in the prior art are produced in the form of frame sequence animation, which has large resources and needs to be downloaded, such as a rotating windmill, which is often a nine-square comic strip, played continuously to achieve the effect of rotation.

Moreover, the video stickers in the prior art are mostly produced in the form of frame sequence animation, which has large resources and needs to be downloaded, such as a rotating windmill, which is often a nine-square comic strip, which is played continuously to achieve the effect of rotation
