How to convert TS to MKV

  1. Add your .TS file - drop it in the box above or click to browse.
  2. Convert it to .MKV in a few seconds.
  3. Download your new .MKV file.

What to expect

  • A lossless remux produces an MKV nearly identical in file size to the source TS - the container change alone does not compress the content.
  • MKV handles AC-3 (Dolby Digital) audio natively, making it more reliable than MP4 for TV recordings with multi-track or Dolby audio.
  • Some PVR recordings have discontinuous timestamps; if the resulting MKV has sync issues, add -fflags +igndts to the FFmpeg command.

Frequently asked questions

Is TS-to-MKV conversion lossless?
Yes, when using FFmpeg or MKVToolNix with stream copy - video and audio data are moved into a new container without re-encoding. HandBrake re-encodes by default, which is not lossless.
Why choose MKV over MP4 for a TS recording?
MKV supports AC-3 audio and multiple subtitle tracks more reliably than MP4, making it the safer target for TV recordings with multiple audio languages or Dolby audio.
Can I select which audio track to include?
Yes - in FFmpeg use -map 0:v -map 0:a:1 -c copy to pick a specific track; in MKVToolNix, uncheck unwanted tracks before multiplexing.
Will FFmpeg's "DTS out of order" warning cause problems?
Usually not - FFmpeg warns but still produces a working MKV. If playback has sync issues, add -fflags +igndts before the -i flag.
