Canon has launched two new high definition camcorders that record HD footage to their own high-capacity internal Hard Disk Drives (HDD).

Building on the success of the award-winning HG10, Canon's HG20 and HG21, wih improvments in both performance and features.

Firstly, both substantially increase the HDD capacity to store huge volumes of film, with 60GB available on the HG20 and 120GB to store of the HG21. This should be enough space to hold around 22 hours and 45 hours of HD video respectively.

Both models also capture and record Advanced Video Codec for High Definition (AVCHD) footage in 1920x1080 "full HD"
resolution, at the maximum data rate of 24mps - providing the best
possible HD video footage available.

In addition to the huge hard disk drives, the Canon HG20 and HG21 also offer support for high capacity SD cards, which means users can choose how they store their footage. Of course, by using Canon's Dual Recording system, users have the ability to easily record to both SDHC memory card as well as recording to the HDD storage within the camcorder.

Both the HG20 and HG21 HD camcorsers from Canon will be available in early September with pricing to be confirmed.
