What is an M2TS file?
M2TS is the transport-stream format used on Blu-ray discs and by AVCHD camcorders when copied to a computer. It is the same structure as MTS with a longer extension.
M2TS is mainly used for Blu-ray video files and camcorder imports. It plays on VLC and some media players; phones and websites usually do not.
