The quality the codec can achieve is heavily based on the compression format the codec uses. A codec is not a format, and there may be multiple codecs that implement the same compression specification – for example, MPEG-1 codecs typically do not achieve quality/size ratio comparable to codecs that implement the more modern H.264 specification.
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) [2] without excessive quality loss, making video CDs, digital cable/satellite TV and digital audio broadcasting (DAB) practical.
The other improved standard, called Digital-VHS (D-VHS), records digital high definition video onto a VHS form factor tape. D-VHS can record up to 4 hours of ATSC digital television in 720p or 1080i formats using the fastest record mode (equivalent to VHS-SP), and up to 49 hours of lower-definition video at slower speeds.

M2TS supports Digital 3D as multiple files in a specific file structure for encoding stereoscopic video: MVC stereoscopic data is in .ssif files in the /BDMV/STREAM/SSIF/ directory and require a respective base .m2ts file. Digital 3D in QTFF and ASF is possible, but not standard. MP4 only supports Digital 3D at the video format level. [44]
D-VHS, on the other hand, does not need to take advantage of this so-called "analog hole", since D-VHS makes possible a pure bit-for-bit recording with no conversion necessary. This is made possible by compliance with CCI flag values carried by the digital streams, wherein only D-VHS is allowed to digitally move recordings of content originally ...
A video file format is a type of file format for storing digital video data on a computer system. Video is almost always stored using lossy compression to reduce the file size. 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. VP9 ) alongside ...
