Understanding MTS files

What is a MTS file?

HD camcorder video format (AVCHD)

MTS files are also Advanced Video Codec High Definition (AVCHD) video files that contain high definition MPEG videos that have been captured by certain models of video camcorders. Originally designed by Sony and Panasonic for their High Definition camcorders, JVC, Sanyo, and Canon camcorders also now record audio and video in the MTS file format. Typically MTS videos have high definition streams and support both 720p and 1080i HD videos.

Common uses for MTS files

  • HD camcorder recordings
  • Consumer video production
  • Event videography
  • Sony camcorders
  • Panasonic camcorders
  • Canon camcorders
  • JVC camcorders

Who works with MTS files?

Documentary filmmakers, local news crews, and families digitizing home videos often have large archives of MTS footage from AVCHD camcorders that were common between roughly 2008 and 2015. Video editors also encounter MTS files when ingesting camcorder SD cards into tools like Adobe Premiere Pro or Final Cut Pro, where the files sit inside the AVCHD folder structure.

MTS vs MP4: which should you use?

MTS wraps H.264 video in an MPEG-2 transport stream, a structure designed for in-camera recording and broadcast-style error resilience, while MP4 uses the MPEG-4 Part 14 container with much broader software and device support. Because both formats commonly carry H.264 video, MTS footage can often be remuxed to MP4 without re-encoding or quality loss. MTS is what you get straight off an AVCHD camcorder; MP4 is the better choice for editing, sharing, and playback on modern devices.

Why won't my MTS file play on my computer?

MTS files use the AVCHD transport-stream structure, which some default media players do not support, and clips copied out of the camcorder's AVCHD folder can lose playback context. Opening the file in VLC or remuxing it to MP4 usually resolves the issue.

Do I need to convert MTS to MP4 before transcribing?

No. You can upload the MTS file directly, and its audio track is extracted and transcribed the same way as an MP4 upload.
