Proc Amp
- Thread starter J. Hart

A proc amp is typically used with analog material to adjust luma and chroma levels. TBC's (Time Base Correctors) usually have proc amp controls built in. Using proc amp controls and Waveform Monitor/Vectorscope, a video signal can be adjusted to meet broadcast specs. NLE's often have a "proc amp" filter to make these adjustments.

It's a "Processing Amplifyer" and yes, it's extremly usefull.
Basically it's what you use to adjust the 4 primary settings of color video:
Brightness
Contrast
Saturation
Phase (/Hue)
It is used to keep a video signal within it's limits and make sure it is "broadcast lagal". It is the main partner for a Waveform Monitor and Vectorscope in any broadcast facility. You will find one built into alsmost any profrasional TBC or Frame Syncronizer.
..and most of the same controls are found in some form or another on almost any display device/monitor.
The adjustments are linear adjustments to the basic signals that make up video.
try a web serach for "how to use a waveform monitor or vectorscope" .. many of the results will refer to these adjustments.
Color Bars ahve been optimized and designed to allow easy adjustment of a signal with a ProcAmp. - The reason you use bars is so the next person in the chain can use their ProcAmp.
A ProcAmp is *vary* important.
