Proc Menu
Adjusting Video Processing Parameters
Video Gain, Chroma, Pedestal and Hue are standard Proc Amp controls affecting the entire video
signal. Use the Proc Menu shown on the next page to adjust these video processing parameters for
the signal:
• Gain – Adjust the percentage of overall gain (luminance and chrominance).
• Chroma – Adjust the percentage of chroma amplitude, which is the color or chroma content
of a signal, consisting of the hue and saturation of the image.
• Pedestal – Adjust the pedestal (black) level of the signal in IRE. The IRE scale is used to
measure the video level, where 0 IRE is black and 100 IRE is full white. The actual voltages that
these levels correspond to can vary between formats.
• Hue – Adjust the hue of the signal ± 180 degrees. The Hue control gives phase rotation of the
color vectors in the manner of an NTSC composite Proc Amp.
