What to expect

  • H.264 3GP video can often be remuxed into the MTS transport stream without re-encoding.
  • An H.263 video track must be re-encoded, which is lossy.
  • MTS wraps the streams in an MPEG-2 transport stream; playback is well supported in VLC but limited in some general-purpose apps.

Frequently asked questions

Is quality preserved converting 3GP to MTS?
MTS carries H.264 video in an MPEG-2 transport stream; when the 3GP already uses H.264 the video can often be repackaged into the transport stream without re-encoding. An H.263 source must be re-encoded with some loss.
Why convert 3GP to MTS?
MTS is the AVCHD format used by Sony, Panasonic, Canon and JVC camcorders, so this matches footage to that camcorder and editing convention.
Where does MTS play?
VLC opens MTS on Windows, macOS and Linux with no extra codecs.
What is different about the container?
MTS uses an MPEG-2 transport-stream wrapper rather than 3GP's ISO Base Media file structure; the audio and video content is the same when the codecs are compatible.
