How can I convert a .m2ts to .mkv?

Question

Does anyone know of an application that allows me to convert an m2ts file to mkv or some other format? Preferably something that allows me to convert it directly, rather than convert the whole Blu-ray disc. hddump didn't work because it doesn't convert only the m2ts file, and the contents are on a .iso that I mounted virtually.

Answer 1

With Handbrake you can convert all kinds of files:

Supported Sources:

• Any DVD or Bluray-like source: VIDEO_TS folder, DVD image, real DVD or bluray (unencrypted -- removal of copy protection is not supported), and some .VOB, .TS and M2TS files
• Most any multimedia file it can get libavformat to read and libavcodec to decode.

Outputs:

• File format: MP4(M4V) and MKV
• Video: MPEG-4(ffmpeg), H.264(x264), or Theora(libtheora)
• Audio: AAC, CoreAudio AAC (OS X Only), MP3, or Vorbis. AC-3 pass-through, DTS pass-thorugh (MKV only)"

Answer 2

ffmpeg

I think ffmpeg will do the job it's quite simply copy all the streams and output them in an mkv container. No information is lost/re-encoded.

ffmpeg -i input.mt2s -scodec copy -acodec copy -vcodec copy -f matroska input.mkv
