About the AVCHD format
What is the AVCHD format?
The AVCHD format is a high definition digital video camera format used to record a high definition (HD)
signal using efficient data compression coding technology. The MPEG-4 AVC/H.264 format is adopted
to compress video data, and the Dolby Digital or Linear PCM system is used to compress audio data.
The MPEG-4 AVC/H.264 format is capable of compressing images at higher efficiency than that of the
conventional image compressing format.
As the AVCHD format uses a compression coding technology, the picture may be disturbed in
scenes where picture, field angles or brightness, etc. change drastically, but this is not a malfunction.
Recording and playback on your camcorder
Based on the AVCHD format, your camcorder records and plays with the high definition image quality
(HD).
In addition to high definition image quality (HD), your camcorder is capable of recording a standard
definition (STD) signal in the conventional MPEG-2 format.
