M2V to AVI

M2V is a video category file format, also called MPEG-2 Video. It supports video with a tighter time constraint and interlaced display. The encoded speed at which data is transmitted may be of the order of 40 Mbps (for storage and transmission). It may be higher for professional use in video production. Large frame sizes do not support HD resolution. MPEG-2 format is compatible with MPEG-1. The MPEG-2 format is used mainly for the consumer level of video broadcasting - for example, DVB. And for storage - for example, DVD. But they are also used for professional applications. Say for storing video in a studio. Files with the extension .m2v are necessary if you are preparing a video for burning to DVD using specialized programs. There will be no sound in such a file. This encoding method also involves the .m2a file, where the sound is stored. Then this pair of files (.m2v and .m2a) will be sent to the authoring program line. The program will output them without recoding in the program stream (MPEG 2 PS). There is one caveat. When the weight of these files is 4.3 GB or more, then you need to transcode this file and reduce the bitrate. So when you create * .m2v, you must first select the correct bitrate.

AVI is a video file format developed by Microsoft. The Video for Windows package, within the framework of which the AVI format appeared, was developed by this company in November 1992. It was intended for the operating system Windows 3.1. Since then, for a quarter of a century, the AVI format has remained the main one for storing video files in all versions of Windows operating systems. The name of the format is an abbreviation of the full name Audio Video Interleave File. The format is used to store video data encrypted using a variety of codecs. AVI files, as a rule, use much less compression in comparison with similar formats.
