Convert MPG to M4V

MPG/MPEG is a file extension that uses MPEG-1 and MPEG-2 codecs for video and audio files. The lossy compression in this format leads to enhancement of the streaming and downloading speed. That is why it is very popular and widely accepted for movies. This format is compatible with both Mac/Macintosh and Windows including some other portable devices. The files that are encoded using this codec provide compressed data that has small size but the quality is not sacrificed at all. It just deletes or neglects the superfluous information that can not be noticed by the human ear. This lossy encoding takes less storage space to store data. Although this format is not efficient enough to provide excellent quality, yet, it is used most of the times due to its higher level of compatibility.

The compressed ratio in digital video files under this format is 26:1 and for audio files it is 6:1.The bit rate in MPEG-1 is about 1.5 million bits per second and it is used to compress CD data., Besides this, MPEG-2 is designed especially for digital TV broadcast and DVD as it uses a bit rate above 4 million bits per second to compress both audios and videos. It should be noted that due to backwards compatibility with MPEG-1, video decoders have the ability to play a lower bit rate. It produces high quality of compressed files. Other uses of MPEG-2 is for Cable network, satellite and television stations; etc. Furthermore, it supports 5.1 multichannel audio.
