The JVC GY-HD100U is a 3-CCD camcorder that uses the HDV codec to capture images in a 24-frame mode. As with other HDV camcorders, this unit can use DV consumer tape and is capable of recording standard definition video as well. Professional details like die-cast all-metal construction and a fine grade Fujinon lens will not disappoint experienced shooters. The camera is a shoulder-mount design for the most stable hand-held shooting positions.
MPEG-2 Based Encoding
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 information 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 downsizing the image.
24-Frame Cine-Style Capture and Recording
Twenty-four frames per second progressive acquisition produces recorded images that have a more polished, film-like appearance than typical interlaced video cameras. 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.
Interchangeable Bayonet Lens
The GY-HD100U includes a bayonet mount 16x Servo Fujinon 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. JVC has developed and patented a focus assist function that highlights detail in the viewfinder to aid with critical detail focusing.
Extensive User-Adjustable Video Looks
Creating a true cinematographic look involves more than just recording at 24 frames per second. The camera's gamma, detail and black levels can be adjusted to the user's preference. When combined with the correct lens filters and lighting techniques, film like performance can be obtained that's tailored to the mood of the scene. There is even a skin tone detection feature that automatically reduces the amount of enhancement in facial areas so that your subjects will not have a wrinkled, television-like appearance. All custom settings can be stored on an inexpensive SD memory card and transferred to another camera if desired.
