Gain: Adjusts the overall signal level of the image in a
linear manner. Increasing Gain will raise the image level
evenly from shadows to highlights. Adjusting Gain will
also affect the Exposure Index (E.I.) value, and allow
you to achieve equivalent ISO values higher than the
preset values. Vision Research recommends not adding
too much Gain (keep it around the default value
of 1.0) in order to maintain the highest image quality.
Pedestal:
Adjusts the baseline black level of the Red,
Green, and Blue channels independently. A default of
0 should produce images with black at 0 on a waveform.
Pedestal can be raised or lowered to a value of 0.10 on
each channel.
Gamma RGB: Adjusts the gamma curve for individual
Red Green and Blue channels independently. By default,
the Master Gamma value will populate each field - then
the gamma curve can be fine tuned for each channel.
There is not a common need for this - this option exists
primarily for video engineers to match the video output
across multiple camera types.
Restore Defaults:
Resets all the settings in the Image
Processing menu to their respective defaults.
The Video & Playback functions allow you to set the
overall video system, playback modes, activate Log mode,
anamorphic mode, color bars and set automatic play
settings. Most of these settings are saved to the raw Cine
file as non-destructive metadata tags, and also applied in
real time to the camera’s various video outputs.
A description for each function is as follows:
Interface: Switches the camera between its acceptable
video output modes: HD-SDI (1080p 4:2:2:); 3G-SDI
(1080p 4:2:2 50P & 60P) and 4K (4:2:2) modes.
