A video file normally consists of a container (e.g. in the Matroska format) containing visual (video without audio) data in a video coding format (e.g ...
Some containers only support a restricted set of video formats: DMF only supports MPEG-4 Visual ASP with DivX profiles. EVO only supports MPEG-4 AVC, MPEG-1 Video, MPEG-2 Video and VC-1.

MPEG-1 is a standard for lossy compression of video and audio.It is designed to compress VHS-quality raw digital video and CD audio down to about 1.5 Mbit/s (26:1 and 6:1 compression ratios respectively) without excessive quality loss, making video CDs, digital cable/satellite TV and digital audio broadcasting (DAB) practical.
