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. - Neil --==--==--==--==--==--==--==--==--==--==--==--==--==--==--==--==--==--==-- Neil Weinstock @ AT&T Bell Labs // "Bust a move short shank, att!edsel!nsw or nsw@edsel.att.com \X/ it's The Man!" - In Living Color
