M2TS (MPEG-2 Transport Stream)

The M2TS Video file format

M2TS files are commonly used to save video and audio data on Blu-ray discs, DVDs, hard drives, or other file storing devices. Those files are saved in high-definition, using the BDAV (Blu-ray Disc Audio/Visual) format. While M2TS files include such BDAV information, the refer mostly to the MPGEG-2 Transport Stream. Additionally, M2TS files are used in a high-definition video recorder format called AVCHD - a simpler version of the Blu-ray disc standard.
