Many cameras and camcorders record videos in MTS which is a container format commonly used for HD video on AVCHD. Unfortunately this format doesn’t work in most video editing software and a lot of media players. If you want to edit your MTS videos, play them on your smartphone, tablet or other devices, or upload them to YouTube, Facebook, etc., you need to convert the MTS files to a more widely used and supported video format such as MP4. Below is a list of the top 5 free MTS to MP4 converter software (for Mac and Windows) and online tools that offer lossless conversion.

Reasons to Convert MTS to MP4

  • ▶ Compared to MTS, MP4 is smaller in size. Small sized files take up less space and transfer faster.
  • ▶ MP4 files are compatible with almost all editing software programs and media players.
  • ▶ MP4 videos can play perfectly on all popular digital devices such as iPhone 8, iPad Pro, Samsung Galaxy S8, etc.
  • ▶ If you shoot a wonderful video and want to upload it on YouTube or Facebook, it’s recommended to convert the video to MP4 format because these sites don’t support MTS files.
