MTS File Format

AVCHD Video category

MTS is the raw AVCHD clip format Sony/Canon camcorders write — high-bitrate H.264 transport streams straight off the memory card.

Typical use: Convert MTS camcorder clips to MP4 without uploading anywhere.

About the MTS format

MTS is what actually comes off a Sony or Canon AVCHD camcorder's memory card: high-bitrate H.264 transport streams with AC-3/PCM audio, often split across a BDMV folder structure. The video inside is excellent — the container is what edit software refuses to import.

Converting MTS to MP4 remuxes or re-encodes into a container every device opens. Stream-copy is possible when the H.264 profile is baseline-compatible; otherwise a light re-encode fixes compatibility without visible loss.

Strengths

  • ✓ Native camcorder quality (24-28 Mbps)
  • ✓ Audio in AC-3/PCM survives remux
  • ✓ ffmpeg handles the transport stream natively

Limitations

  • ✗ AVCHD H.264 profiles not always stream-copyable
  • ✗ Interlaced variants need deinterlacing
  • ✗ 60p modes confuse older editors
