What is the difference between MTS and M2TS?
Both formats come from the AVCHD standard and share the same video and audio streams. MTS is the file recorded directly on the camcorder, while M2TS is the same content once it is copied or imported to a computer or Blu-ray disc. Quality is identical.

Can I convert MTS files without losing quality?
Yes. When the target format uses the same codec, an MTS converter rewraps the video stream instead of re-encoding it, so no quality is lost and conversion is nearly instant. For other formats, choosing a high bitrate keeps the result visually identical to the source.
