With the explosive growth of video data,the pressure on video storage and transmission is increasing.To further improve the compression efficiency of video,this paper designs a coding preprocessing algorithm based on multi-scale feature extraction.The algorithm can be directly embedded before any encoder to achieve plug-and-play.The al-gorithm utilizes a two-stage method to measure the characteristics of encoder effectively.Meanwhile,by designing a multi-scale feature extraction module and a channel attention module,the preprocessing model effectively improves the video compression efficiency.
