To encode the video files the program uses the FFmpeg encoder (ffmpeg.org).

To retrieve information about video files, the program uses the library MediaInfo.dll (http://mediainfo.sourceforge.net/).

The program is accompanied by a special version of the FFmpeg encoder, adapted to the needs of the program. Not recommended to use other versions of FFmpeg.
