Reset
Works on the selected main input source, and when pressed and held for 2 seconds, resets the Color Processor
controls for just that input to 0 or unity. (Press and hold the Reset button until you see the image shake a bit and
return to the unprocessed state.)
So how do you know for certain how effective any of these adjustments are? You can see the changes by looking
at the Main Output on a video monitor, but how do you know if that reference is accurate?
The answer is: by having a calibrated monitor that shows exactly, with reference to a standard, what the video
looks like. That standard has been described and agreed to by the Society of Motion Picture and Television
Engineers (SMPTE) and the European Broadcasters Union (EBU), and is most commonly shown as "color bars."
Color bars are an image consisting of columns and blocks of specific colors and gray tones. Because of
differences in television standards, SMPTE bars and EBU bars do not look the same. They are used in much the
same ways: when these are displayed on a monitor, the monitor can then be adjusted to meet the standard.
Menu - Color Processor
When you press and hold the "Background" (9.) button for 2 seconds or more the
Preview Output displays a Color Processor menu. The controls shown are like picture
controls on a video monitor or the proc amp (processing amplifier) controls on a Time
Base Corrector. In fact, they are the proc amp controls of one of the SE-500's 4 internal
TBCs. This is because the HS-550 is built around the SE-500 mixer.
At the top of screen you will see 4 different channel numbers, each
represent an input from the SE-500 rear panel. On the left side of this
table are the 4 controls (Brightness, Contrast, Color, and Tint
(NTSC only)). Value 0 stands for Unity, or Unchanged. In either case, it
shows that the signal passing through that particular control is neither
boosted nor reduced. To move to another control, press the up or
down arrow button. To move to another channel, press the left or
right arrow button. To change the setting, press the + or - buttons.
You can see the extent of color processing available in this section by experimenting with the controls.
Brightness adjusts how light or dark the colors in the image will appear at the Video Output. The Contrast
controls affect the range between the lightest and the darkest parts of the image, including how much shadow and
highlight detail can be seen. Color controls the saturation or intensity of the color image, from fully saturated or
extremely intense at the top of the scale to de-saturated or monochrome (black and white) at the bottom. The Tint
value controls the actual hue or specific colours in the image (NTSC only), in effect rotating all the colours equally
around an imaginary colour wheel.
