How to convert WEBM to MTS
- Add your .WEBM file - drop it in the box above or click to browse.
- Convert it to .MTS in a few seconds.
- Download your new .MTS file.
What to expect
- Video is re-encoded to H.264 and audio to an AVCHD-compatible codec, since MTS does not carry WEBM's native streams; this is a lossy transcode.
- MTS uses the MPEG-2 Transport Stream structure designed for AVCHD camcorders, so it is best handled by VLC and AVCHD-aware editors.
- WEBM container metadata does not transfer cleanly into the transport-stream format.
Frequently asked questions
Is converting WEBM to MTS lossy?
Yes. MTS is AVCHD video: H.264 carried in an MPEG-2 Transport Stream. WEBM's VP8/VP9/AV1 video is re-encoded to H.264, and any re-encode discards some detail versus the original.
Why convert WEBM to MTS?
MTS is the format AVCHD camcorders from Sony, Panasonic, Canon and JVC record. Converting to MTS suits matching or editing footage in an AVCHD-based camcorder workflow.
What can open an MTS file?
The free VLC media player opens MTS on Windows, macOS and Linux with no extra codecs, and AVCHD-aware editing software reads it as well.
What happens to the audio?
WEBM's Vorbis or Opus audio is re-encoded to a codec AVCHD uses, such as AC-3 or PCM. The audio is rebuilt to fit the MTS container rather than copied straight across.
