JVC Professional GY-HD250
Ergonomic design sets the GY-HD250 apart from its competitors in the $5,000 to $14,000
range. Ten-pound camcorder (with a viewfinder, lens, microphone, battery, and tape) rests
comfortably on your shoulder. Genlock accepts tri-level sync or black burst with controls to
adjust phase (horizontal or subcarrier). Internal timecode generator locks to external sources.
Uses interchangeable lenses designed for 1/3-inch CCDs. Optional studio kit (multicore
adapter, camera control unit, and studio viewfinder) available. Can record 720p HDV at 60 fps.
Editing 720p60 HDV not currently supported by Apple or Avid. If you record in this format you'll
need to uncompress and capture via HD-SDI output. The built-in neutral density filters labeled 1
(ND 0.6) and 2 (ND 0.12) do not offer enough light reduction to shoot day exteriors at stops
below f/5.6. No -dB gain setting. White shading not automatic; the camera doesn't have
standard manual controls, instead using a third approach--RGB controls. Paint controls, offering
a limited range of adjustment, earn a Òjust adequateÓ rating (with the exception of the
saturation control). Operator's manual confusing. The 1080i output cannot be recorded in
camera. Focus assist feature of minimal help.
