M2V to WAV
M2V to WAVM2V 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.
WAV (or WAVE) is actually the first full-fledged audio format with good sound quality. It was developed quite a few years ago by the joint efforts of Microsoft and IBM. Sometimes this format is even called “Audio for Windows,” because it is the standard for storing audio stream for a traditional Windows desktop computer. Full name - Wave Audio File Format. The short name is derived from the English word wave ("wave"). The peculiarity of this format of digitized audio stream is the lack of compression. WAV files take up too much space, but it is ideal for storing high quality files in their original form.
