Aaton XTRprod B&W Video Assist Conversion to Color Flickerfree
The old XC-77 B&W video assist electronics is replaced by a new set which provides the color flickerfree
video image in NTSC or PAL video formats. The conversion to a flickerfree color video assist is designed to
produce a flickerfree monitor image for camera speeds above 10 fps. We offer two versions of the
conversion: version 1 - timecode can be displayed on the monitor screen and version 2- without timecode.

Scanning system: NTSC - 525 lines, PAL -
625 lines, 2:1 interlace
Sync system: Internal
Horizontal resolution: 470 TV lines
Flicker reduction: 100%.
Min. illumination: 1lux, F1.2 AGC:ON
White balance: ATW(auto), 3200K, 5600K
Gain control: 0dB, 4dB and AGC
Timecode can be displayed on a monitor
screen (version 1)
Video output (BNC connector): composite
1V p-p, 75ohm
Power requirement: 12V from the camera's battery
Power consumption: version 1- 3.8W (320mA), version 2 - 2.7W (220mA)

Body: Original XC-77 housing with modified rear switch section
The flicker reduction switch (3 position):
- When set to the lower position, flickerfree mode FF is activated and the green LED is lit. This mode is
designed to produce a flickerfree image for camera speeds above 10fps.
- When set to the middle position, flicker reduction is off and the green LED is not lit. The video assist is in
normal mode. If the iris switch is set to the IRIS 2 position and the gain switch is set to AGC, the normal mode
offers automatic exposure control under a wide range of shooting conditions.
- NTSC - When set to the upper position, flickerfree mode FF30 is activated and the green LED is lit. This
mode provides a 100% flickerfree image when operating at a camera speed of 29.97 fps or 30 fps. In this
mode, flickering is reduced by 70% for camera speeds other than 29.97 fps and 30 fps.
PAL - When set to the upper position, flickerfree mode FF24/25 is activated and the green LED is lit. This
mode provides a 100% flickerfree image when operating at a camera speed of 24 fps or 25 fps.
Flickerfree modes FF , FF30 (NTSC) and FF24/25 (PAL) will only be active when the camera is running.
Once the camera is stopped, normal mode will resume.
