How MTS to MP4 conversion works

MTS file (MTS) stores data in the MTS format. MPEG-4 Part 14 Video (MP4) packages H.264 or H.265 video with AAC audio in a container format widely supported across every platform and device. This conversion changes the file's encoding, compression method, and supported feature set. When the source codecs already match the target container the streams are copied without re-encoding (zero quality loss); otherwise the video is re-encoded at a configurable quality. The result is a standard MP4 file readable by any compatible application. 1converter handles MTS-to-MP4 conversion server-side: files are uploaded over HTTPS, processed on isolated cloud infrastructure, and the converted output is available for download for 24 hours before automatic deletion. No account is required for standard conversions.

When to convert

What the MP4 file is good for and why people convert to it.

  • Plays reliably on phones, tablets, and browsers that expect MP4 containers
  • Usually reduces file size by using efficient H.264 encoding inside MP4
  • Exporting AVCHD camcorder footage for YouTube or social platforms
  • Creating an MP4 master for editing in tools that prefer MP4 timelines

Where your file goes

  • It travels to our server over an encrypted HTTPS connection and is converted there.
  • The MP4 file comes back as a private link. It stops working after 24 hours on Free and 7 days on paid plans, and then the files are deleted.

Questions and answers

What people ask before converting MTS to MP4.

Ask supportAll questions
Will converting MTS to MP4 reduce my video quality?
It depends on the chosen bitrate/codec settings. If you keep a similar or higher bitrate and use H.264, the quality is typically maintained while improving compatibility.
What is different about the MTS and MP4 formats?
MTS is commonly the AVCHD transport/container used by camcorders, while MP4 is a widely supported container that often stores H.264 video with AAC audio.
Will subtitles or multiple audio tracks be preserved?
Audio tracks can be preserved depending on what’s present in the original MTS. Subtitles are only kept if they exist in a compatible form for the conversion output.
Why is MP4 better for playback than MTS?
MP4 is supported by most media players and streaming workflows, while MTS often requires specific codecs or devices that understand AVCHD containers.
