Want to add a video background to your site, but you need to compress your video? Check out Compressify.
Google’s new VP9 codec for WebM format video files offer significant savings on bitrate for practically identical quality video files. Compressify uses an algorithm to automatically detect the optimal reduced bitrate and re-encodes the file, compressing video files by 20-60% with visually identical frames and virtually the same browser compatibility. For best results, compress from your source video.
