What is MTS/ M2TS Format

MTS/M2TS is a filename extension used for the Blu-ray Disc Audio-Video (BDAV) MPEG-2 Transport Stream (M2TS) container file format. It is used for multiplexing audio, video and other streams. It is based on the MPEG-2 transport stream container. This container format is commonly used for high definition video on Blu-ray Disc and AVCHD.

The BDAV container with filename extension .MTS or .m2ts is also used in AVCHD format, which is a high definition digital video camera recorder format. AVCHD is a simpler form of the Blu-ray Disc standard with just one video encoding algorithm and two audio encodings. Compared to Blu-ray Disc format, AVCHD can use various storage media, such as DVD media, memory cards or hard disk drives. The BDAV container contains videos recorded using AVCHD camcorders, such as Sony’s HDR-SR(xx)series models. Panasonic, Canon and other brands of AVCHD camcorders also store recorded video in BDAV container format.

The BDAV container format (.m2ts) is a standard used on Blu-ray Discs. Blu-ray Disc titles authored with menu support are in the BDMV (Blu-ray Disc Movie) format and contain audio, video, and other streams in BDAV container (.m2ts), which is based on the MPEG transport stream format. The BDAV container is also used in the BDAV (Blu-ray Disc Audio/Visual) disc format, the consumer-oriented alternative to the BDMV discs. BDAV disc format is used on BD-RE and BD-R discs for audio/video recording.

The BDAV container format used on Blu-ray Discs can contain one of the three mandatory supported video compression formats H.262/MPEG-2 Part 2, H.264/MPEG-4 AVC or SMPTE VC-1 and audio compression formats such as Dolby Digital, DTS or uncompressed Linear PCM. Optionally supported audio formats are Dolby Digital Plus, DTS-HD High Resolution Audio, DTS-HD Master Audio and Dolby TrueHD. The BDAV container format used on AVCHD equipment is more restricted and can contain only H.264/MPEG-4 AVC video compression and Dolby Digital (AC-3) audio compression or uncompressed LPCM audio.
