What is MTS?

AVCHD (MTS) is a high-definition video format used by consumer camcorders, based on MPEG-4 AVC/H.264 compression.

What is H264?

Raw H.264/AVC is an elementary stream of H.264 encoded video data without container overhead, used in video analysis.

When Should You Use MTS vs H264?

Use MTS When...

Reach for MTS when your priority is hd camcorder video, consumer video editing — its efficient compression makes sharing fast and storage minimal.

Use H264 When...

Reach for H264 when your priority is video codec analysis, raw encoded streams — its efficient compression makes sharing fast and storage minimal.

MTS vs H264: Key Differences

  • •The core technical difference: MTS relies on lossy compression whereas H264 uses lossy compression.
  • •Neither format changes compression philosophy — both are lossy compression — so any size differences are due to encoding efficiency, not a shift in quality approach.
  • •How transparency is handled: H264 does not support alpha channels — transparent areas in the source will become opaque.
  • •MTS files are typically High, 100MB per minute of HD video while H264 files range Much smaller than uncompressed video
  • •Use case fit: MTS targets hd camcorder video, consumer video editing and H264 targets video codec analysis, raw encoded streams — your choice depends on which workflow stage you are serving.

Advantages of MTS

  • ✓MTS applies lossy compression specifically calibrated for HD camcorder video, consumer video editing.
  • ✓MTS enjoys broad native support across operating systems, browsers, and creative tools alike.
  • ✓MTS delivers impressive compression ratios, shrinking files dramatically while keeping visual quality high.
  • ✓You will find MTS support built into virtually every tool that handles HD camcorder video, consumer video editing — no plugins or converters needed.

Advantages of H264

  • ✓H264 compresses data using lossy methods, keeping file sizes manageable for Video codec analysis, raw encoded streams.
  • ✓Industry-wide support means H264 files open anywhere — from legacy systems to the latest devices.
  • ✓Small file sizes make H264 ideal for email, web uploads, and cloud storage.
  • ✓From professional software to open-source alternatives, H264 works out of the box.

Troubleshooting MTS to H264 Conversion

  • !H264 won't play on target device → check codec compatibility (H.264 has broadest support)
  • !Audio out of sync after MTS to H264 conversion → try re-muxing with a different container format
  • !H264 quality is too low → increase the bitrate; for 1080p video, 8-15 Mbps is recommended
  • !File size increased converting MTS to H264 → lossless or higher-bitrate outputs naturally produce larger files
