M1V File - opening and understanding

Did your computer fail to open a M1V file? We explain what they are used for and recommend software that we know can open or otherwise handle your .M1V files.

What is a M1V file?

A .M1V file is a MPEG-1 Video file. An M1V file is a MPEG-1 video file. It is the predecessor of formats like .mpg and .mp4.

MPEG-1 is a standard for lossy compression of video and audio. This means, audio and video compressed (reduced in size) using the MPEG-1 algorithms have lower quality than the original files, but the size is significantly smaller.

It is designed to compress VHS-quality video with an approximate 26:1 compression ratio (output is 26 times smaller than the input), and CD audio with a 6:1 compression ratio - all without too much of a quality loss.
