What is it?
M2TS is the filename extension for the BDAV (Blu-ray Disc Audio/Video) MPEG-2 Transport Stream container format. It is the format used to store the multiplexed audio, video, and subtitle streams on Blu-ray discs and AVCHD camcorder recordings.
M2TS uses a modified MPEG-2 transport stream in which each 188-byte transport packet is prefixed with a 4-byte timestamp, producing 192-byte packets. On Blu-ray the streams are commonly H.264/AVC or MPEG-2 video with Dolby Digital, DTS, or LPCM audio; AVCHD restricts this to H.264 video with AC-3 or LPCM audio.
