Film-Like 24 frame progressive capture and recording
24 frames per second progressive acquisition produces recorded images that have a more polished, film-like appearance than typical interlaced video cameras. That's why virtually all high end digital cinematography cameras utilize the 24P system. The GY-HD100U uses three newly developed 1/3-inch native high definition CCDs that produce a more refined HD look without scaling. Since the native 24 frame material is recorded to tape, it is possible to transfer the recordings to film without frame rate conversion. Time code is recorded in the 24P mode, so recordings made with the GY-HD100U can be edited with film based and high end digital systems with ease.

The GY-HD100U utilizes a progressive scanning system similar to that used in all high end digital cinema cameras. Progressive scanning systems capture and store full frames of information and can be easily converted to interlace signals if desired. When progressive recordings are frozen or played in slow motion, individual frames contain the full detail--excellent for viewing and analyzing motion. Prints that are made from HD progressive frame grabs look far better than typical frame grabs. What's more, all flat panel television displays and fixed matrix projectors, such as D-ILA, DLP and LCD, are native progressive scanning systems and eliminate the need for conversion when displaying GY-HD100U progressive recordings.

JVC is one of the original developers of the MPEG-2 compression system. MPEG-2 is an 'interframe' encoding system that combines multiple frames of digital picture data into a group of pictures (GOP). It then removes redundant informaton from the GOP resulting in far greater efficiency than with 'intraframe' systems, such as DV, that compress every frame separately. JVC pioneered high definition MPEG-2 recording with its D-VHS format--used by major motion picture studios for screening and playback of dailies. JVC's advanced MPEG-2 codecs are used by major television networks and satellite providers. In the GY-HD100U JVC has utilized a highly efficient MPEG-2 codec that compresses the full HD resolution without the 'downsizing the image' used by some competitors.

The GY-HD100U includes a standard detachable 16x Servo Fujinon ProHD lens. Operation is the same as with all professional lenses, with mechanical control of focus, zoom and iris functions. The built-in servo zoom and iris functions can also be used if desired. Other available lens options include a 13x (3.5mm) wide zoom HD lens, a wide-angle converter for the standard 16x lens, an adapter allowing 1/2 inch lenses to be used on the camera and a filter kit. JVC offers rear tripod mounted focus and zoom controls for the standard lenses. Prime lenses can also be used with a 3rd party adapter.
