The Panasonic AG-HMC150 is a camcorder designed to record in
high definition on standard SecureDigital (SD) and SHDC memory cards.
While SD-based camcorders have been gaining ground in the consumer
market, the AG-HMC150 has the ability to record AVCHD images at
significantly higher bitrates. This enhancement makes the camera more
efficient than comparable HD interframe codecs, such as HDV and XDCAM
EX. Using H.264 as its compression algorithm, the camera can record
incredibly detailed images at a fraction of the file size.
