How to Convert M4V to MP4

Check for DRM, then convert

1. 1

   Check if the M4V is DRM-protected

   Movies and TV shows bought or rented from the iTunes Store are protected; your own exports from iMovie, HandBrake or a screen recorder are not. The quick test: open the file in VLC. VLC can't decrypt Apple's FairPlay DRM, so a protected file won't play.

2. 2

   Convert DRM-free M4V to MP4 (rename or remux)

   For DRM-free M4V: simply rename .m4v to .mp4 — they're structurally identical. Or use FFmpeg for a clean remux: ffmpeg -i input.m4v -c copy output.mp4. This is instant and lossless.

3. 3

   Convert with HandBrake (DRM-free M4V)

   Open HandBrake → File → Open Source → select M4V → choose 'Fast 1080p30' preset → set format to MP4 → click Start Encode.

4. 4

   For DRM-protected M4V

   DRM removal without authorisation is legally restricted. The practical solution for purchased M4V is to play them through authorised Apple devices or apps rather than converting.
