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.
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.
The conversion remuxes H.264 video from AVCHD structure to MP4 container.
**AVCHD parsing**: We read MTS files, handling the AVCHD folder structure if present. M2TS and MTS files contain identical content—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 or LPCM audio from camcorders passes through or converts to AAC for broader device compatibility.
**Metadata preservation**: Recording date, camera model, and other AVCHD metadata transfers to MP4.
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 completes in seconds regardless of video length.
