About MTS files
MTS files come from AVCHD camcorders made by Sony, Panasonic, Canon and others. They hold H.264 video with AC-3 or PCM sound in a transport stream, inside a folder structure on the memory card.
Phones, social sites and many editors do not accept MTS directly. MP4 keeps the same video but in a container that everything opens.
How we convert MTS to MP4
- Fast path
- MTS is in our copy-only set. With no options changed, we try to copy the H.264 video into MP4 without re-encoding.
- Fallback
- If the camcorder's sound cannot go into MP4 as it is, we delete that attempt and re-encode to H.264 at CRF 23 with AAC sound at 192 kbps.
- Resolution
- Full HD camcorder footage stays 1080p unless you choose a smaller size.
Common problems and fixes
A long recording is split into several MTS files.
Camcorders split long clips at a file size limit. Convert each file, then join them with our video merger.
The MP4 has no sound in my editor.
Pick a quality preset or set an audio bitrate. That forces a full re-encode with AAC sound, which all editors accept.
Motion looks jagged.
Many AVCHD camcorders record interlaced video. Use a player or editor with deinterlacing for the smoothest result.

MTSからMP4への変換について
AVCHD camcorders from Sony, Panasonic, and Canon record beautiful HD video in MTS format—but this camcorder-specific format doesn't play well outside the camera ecosystem. Converting MTS to MP4 liberates your footage for editing, sharing, and playback on any device.
The conversion is typically simple remuxing since MTS files contain H.264 video—the same codec used in MP4. This means instant conversion with zero quality loss. Your camcorder's pristine footage transfers directly to the universal MP4 format.
MTSをMP4に変換する理由
Editing software compatibility. While professional NLEs support AVCHD, many consumer editors struggle with MTS. Converting to MP4 ensures smooth importing into any editing software.
Universal device playback. MTS files don't play on most smartphones, tablets, or smart TVs. MP4 plays everywhere—share your camcorder footage with anyone on any device.
Online sharing requires MP4. YouTube, social media, and video hosting services prefer or require MP4. Converting before upload ensures proper processing.

仕組み
The conversion remuxes H.264 video from AVCHD structure to MP4 container.
**AVCHD files**: We read individual MTS and M2TS files. They contain identical content, and both convert the same way.
**Stream remuxing**: H.264 video copies directly to MP4 container without re-encoding. This is instant and completely lossless—bit-for-bit identical video.
**Audio handling**: AC3 audio from camcorders is copied into the MP4 as it is. LPCM audio cannot go into MP4, so those files are fully re-encoded to H.264 with AAC audio at 192 kbps.
**Metadata preservation**: Recording date, camera model, and other AVCHD metadata transfers to MP4.
品質とパフォーマンス
MTS to MP4 conversion is typically 100% lossless. Both MTS and MP4 contain identical H.264 video—the conversion simply repackages the streams. Consumer camcorders record at 17-28 Mbps, and this excellent quality transfers completely. MP4 files are essentially identical size to MTS. Remuxing is fast because nothing is re-encoded.
