AVCHD

Part 1: Let's know about AVCHD

AVCHD (Advanced Video Coding High Definition) is a kind of video compression format developed by Sony and Panasonic. It is commonly adopted by camcorders to record and playback high definition videos. AVCHD videos adopts MPEG transport stream container format and has an MTS or M2TS file extension.

Tech Specs

  • Video & Audio Compression:

    The video compression standard of AVCHD is based on MPEG4 AVC/H.264. And it has a wide range of video resolutions including 1080p, 1080i, 720p, 480i, etc. The aspect ratio of AVCHD videos can be the nowadays popular HD 16:9 widescreen or the traditional 4:3 standard.

    As for the audio compression, AVCHD supports Dolby 5.1 channel AC-3 audio as well as uncompressed linear PCM audio. Stereo and multi-channel surround are both supported by AVCHD.

  • Media:

    AVCHD can be recorded and saved in various recording media including 8cm miniDVD (1.4GB-5.2GB), memory cards, solid-state memory and hard disk drives.

  • System:

    AVCHD adopts MPEG Transport Stream which is a standard container format for transmission and storage of audio, video, and other relevant data.

    As you can see in the structure of AVCHD, audio, video, subtitle, and ancillary streams are multiplexed into an MPEG transport stream (MTS) under the directory of BDMV. AVCHD have a Blu-ray like (but not exactly similar) structure, with a BDMV and a CERTIFICATE folder at its root. That's why some Blu-ray player or drive (AVCHD marked) can accept and play AVCHD videos.

    Due to the MPEG Transport Stream container, AVCHD videos always have an mts (on camcorder) or m2ts (after import to computer) file extension.
