Formats
M4V files
Apple's variant of MP4. For practical purposes an MP4 that iTunes and the TV app prefer.
Convert M4V to
Arazio converts M4V to seven formats. All of them sit on the ring.
Tools that work on M4V
Hold ⌥ over a M4V instead of ⇧ and these appear. They change the file without changing its format.
What it keeps
- Lossy — quality is traded for size, and converting repeatedly compounds the loss.
Where the file goes
Beside the original, in the same folder, with the same name and a new extension. Nothing is overwritten and nothing is uploaded — see Privacy and permissions.
Extensions: .m4v · Category: video · M4V converts to seven formats — hold ⇧ and they appear around the cursor.
