5 Best MTS to MP4 Converters in 2026

Got MTS clips sitting in a camcorder folder? MP4 copies are easier to watch and share. I’ve rounded up five ways to convert them, including free apps and the one I made.

1. How to Convert

Mac, Windows, Linux · $29 once

This is the one I made. How to Convert handles almost any file, so the same app works for video, music, photos and documents. You choose the output and click Convert; it finds and runs the tools for you.

  1. 1. Add your files. Drag your MTS files into How to Convert.

  2. 2. Choose the output and convert. Choose MP4 from the output menu and click Convert.

This makes a new MP4 by re-encoding the video.

Other options

2. HandBrake

Mac, Windows, Linux · Free

Free video conversion with presets and a queue. It re-encodes the picture rather than copying existing video unchanged.

  1. Click Open Source and select your MTS file.
  2. Select General → Fast 1080p30 in Presets and check that Format is MP4. This is a useful starting point for an ordinary sharing copy.
  3. Choose a filename and destination, then click Start or Start Encode. Play the finished MP4 on the device that needs it.

If moving edges show horizontal lines, try HandBrake’s Decomb filter. Check long recordings for missing segments before deleting anything from the camera.

3. Shutter Encoder

Mac, Windows, Linux · Free; donations welcome

Its Rewrap option can make an MP4 without changing the video, when the video and audio formats are compatible.

  1. Add your files, choose Rewrap and set the extension to .mp4.
  2. Choose an output folder and click Start function. If the result will not play, use H.264 conversion instead.

A paid option with trimming tools. Trial exports have restrictions.

  1. Add your video files, choose MP4 in the output formats and pick a preset matching your resolution.
