NTSC Bars 1.0 by Craig Marciniak June of 1992
What is this _______________________________________________
NTSC Bars 1.0 tries to be a NTSC compliant colorbar generator for your mac.
This utility will come in handy for anyone, although it was designed for
video production use, anyone with a color macintosh can benefit from it,
for it is useful for setting brightness and contrast settings. I tried to get
as close to the NTSC RS170A standard as I could.
To Use ____________________________________________________
Your Monitor needs to be set to 16, 256, thousands, or millions colors
Turn your monitors brightness and contrast all the way up,
Under the red bar you will notice three small rectangles of various shades
of gray, Turn the brightness back until the the first two gray strips blend.
That's it.
Did you know _______________________________________________
If you are doing video production you must be careful on the colors that
you select, even though your hardware sends out a NTSC signal, most
hardware does not filter the signal and correct the color to be within
NTSC legal values. For example, have you ever transferred Mac graphics to
video tape or have seen videos, where bright blues or reds
have a "tearing" effect? This is caused by clipping (distortion), which is
analogous to turning a stereo up too loud and over driving your speakers
causing distortion. Ergo, a pure digital blue signal out of your Mac is
too strong for NTSC to deal with and it distorts causing the "tearing effect."
Shortcomings _____________________________________________
This version does not support multiple monitors, if I get any response
I might add it?
