What is a .M2T file?
M2T carries MPEG-2 video in the transport stream used by HD camcorders and broadcast.
- Did you know
- The transport stream was built to survive the errors of broadcast and tape.
- Transport-stream data is chopped into fixed 188-byte packets so interleaved programmes survive the dropouts of broadcast and tape.
- HDV camcorders adapted the format by adding a timecode to each packet, the variant usually seen as M2TS.

- Depth of analysis
- .M2T is an identification-grade format: Analyser recognises it from its bytes and decodes the header metadata it carries, rather than opening it in a full viewer. Formats that do get a full viewer are marked "Full" on the formats page.
- Open a .M2T file
- Drag a .M2T file onto the Analyser home page (or tap to pick one). It is identified entirely in your browser - nothing is uploaded, there is no account, and it works offline once installed.
