Flickerfree NTSC or PAL Color Video Assist

A video assist (video tap) is an accessory for a motion picture camera that provides a video feed from

the camera lens. It is used to allow the director or operator to see on a video monitor or computer screen what

is in the camera's frame without having to look through the viewfinder, as well as allowing video to be

captured that can be used to create an immediate rough cut, if needed. If the motion picture camera runs at a

frame per second rate (e.g. 24 fps) different from the video frame rate, NTSC: 29.97 fps, PAL: 25 fps, then

the monitor image will flicker. The flickerfree video assist is designed to produce a 100% flickerfree monitor

image for camera speeds ranging from 10 to 150 fps. A Sony CCD (Charge Coupled Device) solid stage

EXview HAD (Hole Accumulated Diode) image sensor provides it with high resolution, high sensitivity and

outstanding color fidelity. The computerized video assist electronics allows the image to be electronically

flipped horizontally and/or vertically, which is useful when operating the unit with various video optics systems

(different cameras, e.g. Arriflex or Aaton). This video assist can be supplied from a 12 V or 24 V battery

(autoranging) and is equipped with a noise filter which provides a clear monitor image even if the camera

motor is noisy. The low power consumption, only 220mA/12V or 130mA/24V, gives your camera battery a

longer life.
