JVC has added three new high definition camcorders to its HD Everio line in the States.

The new models include a pair of dual-format devices, the GZ-HD40 and GZ-HD30, one of which records up to 50 hours of AVCHD Full HD video.

Claiming a world's first for the AVCHD/MPEG2 dual-format capabilities, both offer 1920 x 1080 Full HD recording in both formats to a 120GB (GZ-HD40) or 80GB (GZ-HD30) internal hard disk drive.

The third new model, the GZ-HD10, offers 1440 x 1080 recording in the AVCHD format to a 40GB hard drive.

The camcorders feature new CMOS imaging chips with interpolation technology, noise reduction technology and 1920 x 1080/60p output via HDMI.

The GD-HD30 is more compact than the GZ-HD40, with an 80GB internal hard disk that offers up to 33 hours of Full HD recording. JVC says as of June 2008, it is the world's smallest Full HD camcorder with 1.8-inch HDD.

The GZ-HD40's 120GB hard disk drive offers 50 hours of AVCHD Full HD video recording, and a docking station to meet the requirements of the prosumer or high-end enthusiast.

The HD Everio GZ-HD10 is aimed at the "budget-conscious" and gets a KONICA MINOLTA HD LENS and a 40GB hard disk that provides up to 16 hours of high-definition recording. The GZ-HD10's 1440 x 1080 AVCHD recordings are also up converted for playback at 1920 x 1080/60p via HDMI.

All three models will be available in the States in August, the GZ-HD40 is $1299, the GZ-HD30 is $999 and the GZ-HD10 is $799. No UK availability has yet been revealed.
