How to Convert MTS to AVI on Windows/Online

Melissa Lee updated on Mar 15, 2023 | Home > 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.

MTS also adds encryption, which may make it not playable on computers. Lastly, the MTS file size is more significant than AVI, making it not favorable for those who do not have enough storage space. That is why people want to convert MTS to AVI. And in this post, you will find a list of software and online tools to convert MTS to AVI.
