How to convert MTS to M4V
- Add your .MTS file - drop it in the box above or click to browse.
- Convert it to .M4V in a few seconds.
- Download your new .M4V file.
What to expect
- Video and audio move into an MP4-style container; when the H.264 stream is copied rather than re-encoded, there is no quality loss.
- Any re-encode to change resolution or bitrate is lossy, so avoid repeated round-trips through re-encoding.
- The output is DRM-free; M4V's FairPlay protection applies only to store purchases, not to converted footage.
Frequently asked questions
Will the video quality drop when I convert MTS to M4V?
Both formats carry H.264 video, so if the stream is copied straight across the picture is identical. If it is re-encoded to fit M4V settings, that is a lossy step and some detail is lost, though at a matched bitrate the difference is usually hard to see.
Why convert AVCHD MTS footage to M4V?
MTS is a camcorder transport-stream format that many editors and Apple apps handle awkwardly, while M4V uses the MP4-style container Apple's ecosystem expects. Converting makes the HD footage easier to bring into Apple TV, QuickTime and iTunes-oriented workflows.
Where will the resulting M4V file open?
A non-DRM M4V plays in VLC, QuickTime and Windows Media Player, and in Apple's Music/TV apps. A converted camcorder clip has no FairPlay DRM, so it behaves like an ordinary MP4-family video everywhere.
Does M4V add any DRM or copy protection?
No. FairPlay DRM only appears on M4V files sold through Apple's store; a file produced by converting your own MTS footage is plain, unprotected video that any compatible player can open.
