A method for recording and editing long videos through mobile terminals

Abstract

The invention discloses a method for recording and editing a long video through a mobile terminal, which includes recording a first video and encoding the first video; saving the last frame of the first video and generating a transition animation; recording the second video, And the second video is encoded and processed; the first video, the transition animation and the second video are merged to obtain the third video, and the third video is subjected to picture rendering processing to obtain a long video that completes recording and editing, and adopts the method provided by the present invention The solution can not only quickly record and access video, but also generate animation based on animation real-time check calculation, which not only saves resource space, but also makes 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
