I was in a store the other day watching an A3000 running a Commodore-supplied
demo. Not too bad; it was comparable in style to the typical demos you see
running on PClones. Could've used some more impressive animations, I thought,
but hey.
Anyway, the demo did a couple of things where it would pull down its screen to
reveal a HAM picture beneath. The downward movement of the front screen
did not appear to be completely smooth. Later, a random customer was watching
the demo and asked why it "flickered". I didn't really know what he meant,
but the salesman replied "It's the monitor". The customer replied "It looks
pretty nice overall, except for the flicker."
This got me to thinking of a couple of questions:
1) Why was the screen movement not smooth? I could only think of
two possible reasons: programmer incompetence or the deinterlacer.
Could the deinterlacer have an effect?
2) In many programs, a screen is made to fade to black. The fade
never really looks smooth. My only guess would be that 4 bits
for R, G and B just isn't enough, and that each change is very
noticeable. Has anyone ever been able to effect a really smooth
fade of a color image?
"It's the monitor". Sheesh, what a yoyo.
