MTS is an Advanced Video Coding High Definition (AVCHD) format. The format is the standard video format used by many Sony and Panasonic HD camcorders. MTS files are also used for storing high definition video on Blu-ray discs. So normally speaking, MTS videos should have a great performance in terms of the video and audio playback.
