Frequently asked questions
Does it work with DRM-protected M4V?
No: FairPlay-protected videos can't be converted, and we don't try to break that protection.
What's the difference between M4V and MP4?
Almost none: M4V is Apple's flavor of the MP4 container, sometimes with chapters or extra tracks. That's why the conversion is an instant copy.
Is quality lost?
No: it's a container swap with no re-encoding.
What if my M4V doesn't work?
If it carries unusual codecs, use the universal video converter, which re-encodes to H.264.
