What is an MTS File Joiner

MTS is a file extension for AVCHD format that is used to run high definition videos.

Clideo's MTS Merger works online which means that you don't need to download it to your device. It's also completely free for files up to 500 MB.

The tool allows you to combine any number of images and videos together, add music, and adjust the result.
