Convert m4v to sd2

What is the difference between .m4v and .sd2?

Description: The M4V file format is a video container format developed by Apple and is very similar to the MP4 format, with the primary difference being the optional Apple Digital Rights Management (DRM) protection. M4V files are commonly used for TV episodes, movies, and music videos in the iTunes Store. These files can be played on Apple devices such as iPhones, iPads, and iPods, as well as on PCs using iTunes or other compatible media players.; The Sound Designer II file, with the extension .sd2, is an audio file format that was originally developed by Digidesign for their digital audio workstation software, specifically for use in professional recording and editing environments. The format was widely used for its high-quality audio data storage and was particularly popular in the late 80s and 90s. It supports multiple audio channels and bit depths, making it versatile for various audio production tasks.
