M4V Converter
M4V is an MPEG-4-family file extension commonly seen in Apple-oriented media workflows. Its practical compatibility depends on the video/audio streams inside the file.
When this format makes sense
Use M4V when the target application or device expects the extension.
Treat the extension as a container hint, not a guarantee of codec compatibility.
Check whether remuxing can achieve the desired result without quality loss.
