While AVCHD is relatively new, AVC is an established standard-particularly in the streaming space, where, with Apple ’s backing, it serves as the primary codec for iPod video. AVC/H.264 is an advanced subset of MPEG-4 compression (MPEG-4 Part 10 to be specific), so sometimes the terms are used interchangeably-although in most instances, references to MPEG-4 are to the older codec, not AVC. For this reason, it’s a standard you need to know about, even though you may not use it for a while.ĪVC-Intra is expected to debut as an optional encoder board for the Panasonic AJ-HPX2000 P2 HD camcorder, and it is expected to double the capacity of the P2 card.ĪVCHD stands for Advanced Video Codec High Definition, and it’s based upon the AVC codec, a joint standard of the ITU (International Telecommunications Union) and ISO (International Standardization Organization) groups.
Given that the MPEG-4 technology that fuels AVCHD is roughly twice as efficient as the MPEG-2 technology used in HDV, the new Sony -Panasonic standard will likely supplant HDV in the prosumer space. Although AVCHD first appeared in consumer camcorders, a variation-AVC-Intra-will soon show up in broadcast cameras from Panasonic.
