What is M4V?
M4V files are iTunes Video Files. The M4V file format is a standard file format for videos for iPods developed by Apple. Nowadays, Apple’s products like the iPod, iPhone, and iTunes Store, are becoming more and more popular so M4V files are becoming more commonly used. The M4V file format is based on the MPEG-4 AVC video compression, which is a global media standard with the aim to provide optimized video podcasts for the iPod.
What is AVI?
AVI - which stands for Audio Video Interleave
A Container format used by Microsoft's Video for Windows multimedia framework. Since it was developed for Windows 3.1 in 1992 it lacks some features found in newer containers like MPEG or MP4, but is still widely used by consumers and even supported by some standalone DVD players. Although still supported in Windows, and suitable for certain formats like DV, it's not a good general purpose container, and even Microsoft uses other containers for their own video formats
