Frequently asked questions
Does converting M4V to MOV reduce quality?
Not with a stream-copy remux - FFmpeg's
-c copy transfers video and audio data unchanged. Re-encoding via QuickTime Player will introduce a small quality change.Can I convert a DRM-protected M4V to MOV?
No. FairPlay DRM-protected files from Apple TV or iTunes are encrypted and cannot be processed by any standard converter.
How long does M4V to MOV conversion take?
A stream-copy remux is limited by disk speed - a 4 GB movie typically finishes in under 30 seconds. Re-encoding takes several minutes depending on file size and CPU.
Are chapters and metadata preserved?
Yes - with FFmpeg
-c copy, iTunes chapter marks, embedded subtitles, and cover art transfer to the MOV file intact.
