How to convert M2TS to MP4
- Add your .M2TS file - drop it in the box above or click to browse.
- Convert it to .MP4 in a few seconds.
- Download your new .MP4 file.
What to expect
- Remuxing with
ffmpeg -c copywraps the existing H.264 or HEVC stream into MP4 with no quality change; HandBrake re-encodes by default, which takes longer but looks identical at standard quality settings. - Dolby TrueHD and DTS-HD audio cannot be stored in MP4 - these tracks are transcoded to AAC automatically, which means the lossless audio quality is lost.
- If your footage is 1080i (interlaced), enable deinterlace in HandBrake before converting to avoid combing artifacts in the output.
Frequently asked questions
Does converting M2TS to MP4 reduce quality?
Only if you re-encode. Remuxing with
ffmpeg -c copy preserves the original video stream unchanged; HandBrake re-encodes at CRF 22 by default, which is visually lossless for most content.What happens to Dolby TrueHD or DTS-HD audio?
MP4 does not support those codecs, so converters replace them with AAC - you keep the audio but lose the lossless quality.
Can I convert a commercial Blu-ray M2TS file?
Commercial discs are encrypted at the disc level; the
.m2ts file can only be converted after decryption, which may be restricted in your jurisdiction.Why won't M2TS play in Windows Media Player?
Windows Media Player lacks built-in support for the BDAV container; install VLC to play the file directly, or convert it to MP4 first.
