What is an MTS file?

MTS, short for MPEG transport stream, refers to a video file saved in AVCHD (Advanced Video Coding High Definition) format. It is widely used to record HD videos on Sony and Panasonic HD camcorders as well as store HD videos on Blu-ray discs. A .mts file is often compressed using MPEG-4 and Dolby AC-3 codecs and capable of storing 1080p and 1080i HD videos.

But after transferring among different software or importing MTS files to post-editing software like Final Cut Pro, DaVinci Resolve, and Adobe Premiere Pro, you may encounter errors to open the files or find no sound.

The key reason lies in the compatibility – video codec and file extension. The simple and effective solution is to convert MTS to MP4, a universal video format. Now check the top 3 easiest ways of how to convert MTS to MP4 without losing quality.
