How to convert MTS to M2TS
- Add your .MTS file - drop it in the box above or click to browse.
- Convert it to .M2TS in a few seconds.
- Download your new .M2TS file.
What to expect
- No video or audio data is changed - M2TS adds only a 4-byte timecode header to each transport stream packet for disc navigation.
- Keep the full AVCHD folder structure (including
CLIPINFandPLAYLISTfiles) if you plan to re-author a Blu-ray disc; copying only the.mtsfiles loses clip metadata. - If your goal is everyday playback or editing rather than disc authoring, convert to
.mp4instead - it is compatible with virtually every player and editor.
Frequently asked questions
Can I just rename .mts to .m2ts?
Not reliably - the packet size must change from 188 to 192 bytes when adding the timecode header, so a simple rename produces a file with the wrong packet structure that may confuse disc authoring tools.
Is M2TS better quality than MTS?
No. Both formats carry identical H.264 video and AC-3/PCM audio; M2TS only adds a small timecode header per packet for disc navigation.
How long does the conversion take?
Very fast - since no re-encoding is needed, a 4 GB file typically converts in under two minutes with tsMuxeR or FFmpeg.
Do I need M2TS to edit my footage?
No - editors like Premiere Pro, DaVinci Resolve, and Final Cut import
.mts files directly; convert to M2TS only when a disc authoring tool specifically requires it.Programs that convert MTS: 4Free Video Converter · Adobe Media Encoder · Adobe Premiere Pro · Free Studio · Freemake Video Converter · Cyberlink PowerDirector · Sony Vegas · iVI - iTunes Video Importer
