MTS and M2TS are Sony high definition video file types, both of which are recorded by AVCHD camcorders. So it's no surprise that many popular HD camcorders, like Canon VIXIA HF200, Canon FS200, Canon VIXIA HFS100, Canon VIXIA HG21, Panasonic HDC-HS300, Panasonic HDC-HS20, Sony HDR-CX100, Sony DCR-SR47, JVC GZ-HD40, JVC GZ-HD10 etc. record videos in MTS/M2TS format.
