How to convert M2TS to MTS

What to expect
- When the source video is H.264, the stream is usually rewrapped rather than re-encoded, so quality is unchanged.
- Dolby, DTS or PCM audio tracks carry over as-is inside the transport stream.
- This is a container and extension change, not an improvement in compression or resolution.
Frequently asked questions
Does converting M2TS to MTS reduce the video quality?
Both M2TS and MTS are MPEG-2 Transport Stream containers, so when the video is already H.264 the existing stream can be rewrapped without re-encoding, keeping the original quality exactly. A quality loss only occurs if a re-encode is forced for some target device.
Why convert M2TS to MTS at all?
M2TS is the naming Blu-ray and BDAV use, while MTS is the extension AVCHD camcorders and many editors expect. Matching the
.mts extension and container makes the same footage line up with AVCHD-oriented software.Where will an MTS file open after conversion?
MTS plays in VLC on Windows, macOS and Linux and is recognized by AVCHD-aware video editors. The underlying data is the same transport stream that M2TS carried.
What is lost when I convert M2TS to MTS?
In a straight rewrap nothing in the picture, the Dolby/DTS/PCM audio, or the timing is lost, since both are the same container family. Only BDAV structures specific to Blu-ray playback, which an AVCHD-style file does not need, may be left out.
