What to expect

  • When the MP4 uses H.264, the audio and video can often be remuxed into M2TS losslessly.
  • M2TS is a transport-stream container aimed at Blu-ray/AVCHD, with codec constraints.
  • Streams that do not match those constraints require a lossy re-encode.

Frequently asked questions

Does MP4 to M2TS keep video quality?
M2TS is the Blu-ray/AVCHD transport-stream container and commonly holds H.264, which MP4 also uses, so the video can often be remuxed without re-encoding and stay lossless. Only if the codec must change is quality affected.
Why convert an MP4 to M2TS?
M2TS is the format used on Blu-ray discs and by AVCHD camcorders, so it is used to author discs or feed hardware and TVs that expect transport-stream clips.
Where does an M2TS file play?
VLC plays M2TS for free on any platform. On a Blu-ray it lives in the BDMV\STREAM folder as numbered clips, and many media players and TVs read it directly.
What limitations should I expect?
M2TS expects specific codecs (H.264, VC-1, MPEG-2) and audio like Dolby, DTS, or PCM, so incompatible source streams must be re-encoded. Not all lightweight players open transport streams as smoothly as MP4.
