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 PAL or NTSC 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.
Specifications:
Power on/off switch (2 position): same as in the B&W unit.
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.
- 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.
TimeCode
switch (3 position):
- Lower: timecode is displayed at the bottom of the monitor
screen.
- Middle: timecode is not displayed on the monitor screen.
- Upper: timecode is displayed at the top of the monitor screen.
In order to display timecode, the timecode has to be initialized in the Aaton camera (e.g. by Origin C ). The timecode is displayed on the monitor screen in the following format: P followed by a 6 digit production number, date: month/day/year (or day/month/year in the PAL version), time: hours:minutes:seconds. If the camera is running, the letter R will be displayed after the production number.
White
balance switch (3 position):
- Lower: 5600K (fixed) - for outdoor shooting on sunny days.
- Middle: 3200K (fixed) - for indoor shooting under incandescent
light.
- Upper: Auto White Balance is ON. The white balance is adjusted
according to the color temperature transition of the subject.
This mode is suitable for shooting with variable lighting.
Gain
control switch (3 position):
- Lower: gain control is set to 0dB.
- Middle: gain control is set to 4dB.
- Upper: auto gain control (AGC) is ON.

conditions.

conditions.

conditions (outdoors on a sunny day).
