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.
