Vanessa Chiang updated on Aug 18, 2021 to Video Converter Tips

MTS or MPEG Transport Stream is a container format containing audio, video, and anything else to make it possible to distribute over media such as DVD, Blue-ray Disc, and others. While it works well, AVI is the format that can be compatible with more players than MTS.
