Cheet Sheet: AVCHD
As high definition continues its steady domination of the TV market, in the camcorder market high definition is only a blip on the consumer radar. Cost has been the major drawback. High definition camcorders can cost several times their standard definition brethren. Add to that the issue of complexity. High definition camcorders don’t lend themselves to easy dubbing, archiving or editing, and generally require a level of expertise and time that most home movie makers don’t have. Some manufacturers, namely Sony and Panasonic, hope the adoption of the new AVCHD format will start to change the high def video situation. He’s a brief of what the format is all about.
What is AVCHD?
AVCHD is a new camcorder format for high definition video. The specification 1.0 supports resolutions of 1080 (50i, 60i, 24p) and 720 (50p, 60p, 24p). It uses the MPEG4/AVH.264 codec, which supporters say is two times more efficient than MPEG2 or other MPEG4 codecs. The HDV format, on the other hand, used MPEG2. It was created jointly by Sony and Panasonic, and announced in the summer of 2006. Sony was the first manufacturer to release a camcorder that records in AVCHD, but others have since been released or announced.
