Free program for hiding information in video. Data that you hide can be recovered even from compressed video, or if the video was compressed again by another codec! We smartly change video with understanding how codecs works, introducing small amounts of noise. You can hide not so big files, but for cipher communication or video secret marking it is enough! You can manage redundancy of information in film - if you want to compress video with low bitrate, you should increase redundancy, and vice versa.
