If you don’t have any video test equipment, follow the suggested procedure to adjust all the video sources,
which is described at the end of Appendix: Monitor Calibration, page 55.
Settings made in this section are “remembered” by the SE-800 after you power down the unit. In other words,
these settings remain in effect until they are changed or either the Reset or the Reset All button is pressed.
RGB color correction
RGB color correction can only be engaged when the Input Format section is active
(see above) and works on the channel selected in that section of the controls. Its
purpose is to perform white balance correction, compensating very precisely for an
overall color shift in the image. The color shift can be caused by a number of
factors, for example poor white balance settings on the video camera or poor
lighting conditions.
To activate the RGB Color Correction control, press the button beneath the joystick
once, and the LED on the left will light. Operate the control by moving the joystick
around and observing how the colorcast of the image changes as seen on the output monitor. Notice also
that the windows above the Keypad show changing numbers as you rotate the joystick. The number in the
left window is a read out of the vertical and horizontal position of joystick. “0” is at the middle, “9” is at the
end edge position. The symbol in the right window shows graphically the quadrant of the color wheel where
the correction is taking place (upper left, lower right, etc.).
Settings made in this section are “remembered” by the SE-800 after you power down the unit. In other words,
these settings remain in effect until they are changed or the Reset All button is pressed (see Color
Processor, above).
As we said above (in the Color Processor section), it is vitally important to perform RGB Correction only with
a properly adjusted monitor and/or a waveform monitor/vector scope (if at all possible), so that you can be
fully confident of the results. And that is the point: to be confident of the quality and colors at the output of the
SE-800. When you change any aspect of how the video looks, you are actually changing the video signal.
This is not a big deal if you are just looking at one signal on a monitor, but it becomes much more
complicated when you try to combine signals (such as in a dissolve) and/or try to record the results.
