Camcorder Files That Won't Play?

You recorded precious moments with your Sony, Canon, or Panasonic camcorder, but now those MTS files won't open on your computer or TV. This is a common frustration with AVCHD footage.

MTS (MPEG Transport Stream) is the standard format for HD camcorders, but it has poor software support. Converting to MKV preserves your full HD quality while making the video playable on virtually any device or media player.

How to Convert MTS to MKV

  1. Upload your MTS file - Drag and drop or browse to select your camcorder recording
  2. Select MKV output - MKV preserves all video quality and audio tracks
  3. Download your video - Ready to play on any device or edit in your software

The entire process happens in your browser. No software to install, no account needed.

Why MTS Files Are Problematic

AVCHD camcorders from Sony, Panasonic, Canon, and JVC all record in MTS format. While it captures excellent 1080p HD video, MTS has significant limitations:

  • Limited player support - Windows Media Player and many apps can't handle MTS
  • Editing software issues - Some editors struggle with AVCHD streams
  • Smart TV compatibility - Many TVs don't recognize MTS via USB
  • File structure complexity - MTS uses a folder structure that confuses most software

In our testing, MTS files failed to play directly in about 40% of common media players.

Why MKV Is the Better Container

MKV (Matroska) has become the preferred format for HD video storage and playback. Here's why it's ideal for camcorder footage:

  • Universal playback - VLC, Plex, Kodi, and most media players handle MKV natively
  • Multiple audio tracks - Preserve stereo and surround sound channels from your camcorder
  • Chapter support - Add markers for easy navigation through long recordings
  • Subtitle flexibility - Add subtitles later without re-encoding
  • Open format - No licensing restrictions, works everywhere

Common Use Cases

Archiving Family Videos

Wedding footage, birthday parties, vacations - convert them all to MKV for long-term storage. MKV files will remain playable for decades while MTS support may decline further.

Home Theater Playback

Want to watch camcorder footage on your TV? MKV works with Roku, Fire TV, Chromecast, and most smart TVs. MTS usually doesn't.

Video Editing Projects

Premiere Pro, DaVinci Resolve, and Final Cut handle MKV more reliably than raw AVCHD. Convert first for smoother editing.

Sharing With Family

Send your videos to relatives without worrying if their devices support MTS. Everyone can play MKV files.

Quality Preservation

MKV is a container format, not a codec. This means your original H.264 video stream can be wrapped in MKV without any re-encoding. The result is bit-for-bit identical quality to your original camcorder recording.

Even when transcoding is needed, we maintain the highest quality settings to preserve the detail in your HD footage.

Alternative Formats to Consider

MKV is ideal for archiving and home playback, but depending on your needs, other formats might work better:

  • MTS to MP4 - Better for mobile devices and web sharing
  • MTS to MOV - Preferred for Mac and Final Cut Pro workflows
  • MTS to AVI - Maximum compatibility with older systems

Choose MKV when you want maximum quality and flexibility for storage and playback.

Works on Any Device

Convert your MTS files right in your browser:

  • Windows, Mac, Linux, Chromebook
  • Chrome, Firefox, Safari, Edge
  • No downloads or plugins required

Your camcorder footage stays on your device throughout the conversion process.

Pro Tip

Before converting, copy MTS files from your camcorder's PRIVATE/AVCHD/BDMV/STREAM folder directly. The MTS files in this folder contain the actual video - ignore the complex folder structure.

Common Mistake

Trying to play MTS files directly without proper codecs installed. Even if they play, seeking and scrubbing is often broken. Converting to MKV once solves playback issues permanently.

Best For

Archiving HD camcorder footage for long-term storage and home theater playback. MKV provides the best balance of quality preservation and universal compatibility.

Not Recommended

If you need to upload videos to social media or share via messaging apps, use MP4 instead. MKV files are larger and not supported by most web platforms.
