The MTS extension is used by files saved in the Advanced Video Coding High Definition (AVCHD) format. MTS are multimedia files based on the MPEG-2 Transport Stream container which is used for multiplexing video, audio and other streams. The AVCHD format supports resolutions of up to 1080i.

The Advanced Video Coding High Definition technology was established by Sony in conjunction with Panasonic in 2006 to be used with their high-definition camcorders. Later, Sanyo, Canon and JVC also adopted it. Besides video and audio content, the AVCHD format also includes media presentation features such as subtitles, menus and slide shows.

How to open MTS files

MTS files can be opened with a wide range of media players on all major operating systems. They can also be viewed with Sony, JVC, Panasonic, Canon and Sanyo camcorders and opened with the software sold with each camera.
