The MTS format is commonly used to store HD video on AVCHD and Blu-ray discs. Because of their high resolution, MTS files can get pretty large. To be played on portable players and other mobile devices, MTS files need to be converted to a more appropriate format.

MTS multimedia files contain video and audio saved in the AVCHD (Advanced Video Coding High Definition) format. This format was developed by Panasonic and Sony in 2006, which is why so many camcorders made by Sony and Panasonic use AVCHD as the standard format.
