How to convert RM to MTS
To convert RM to MTS, upload your RM file, choose MTS as the output format and press Convert. The finished MTS file is ready to save to your phone or computer in seconds, free, with no watermark and no sign-up. Your file is deleted from our server about 30 minutes after the conversion.
This free online converter turns RM videos into MTS files in your browser, with no software to install and no watermark. When the video and audio inside your RM file can be placed in MTS as they are, the streams are copied without re-encoding, which is faster and keeps the original quality. Otherwise the video is re-encoded as H.264 video with AC-3 audio in AVCHD-style 192-byte packets.
Reasons to switch from RM to MTS
- Stores high-definition H.264 footage
- Native output of many camcorders
- Keeps full camera quality
- Plays on: Camcorder software, VLC and professional editors; limited on phones and the web
What to expect from this conversion
- Expect a larger file than the RM original, because MTS is a less efficient format for the same quality.
- MTS output uses 192-byte AVCHD-style packets with H.264 video and AC-3 audio.
- RealMedia files are low-resolution by nature, so the result keeps the same detail level. Converting does not add detail.
- The first audio track is kept. Subtitle tracks, extra audio tracks and chapters are not included in the converted file.
