#Par output problem
5 messages in this thread
Hi Don-
I've got a video question I want to throw your way. (VBG)
(I've save a bunch of your video thread because they are so informative; I was
hoping you might have a quick fix for me.)
I've got this very dim (almost invisible) slow moving bar that scrolls up my
screen from bottom to top when the par is playing an animation. The bar
alternates; first its dark, then it is followed by a lighter bar that slowly
scrolls by. The whole phenomena is continous, and when the par software is
loading I can see the scrolling bar shiver as my harddrive kicks in.
Any ideas? I'd really appreciate anbody's ideas on what's happening. I'm
hoping one of the adj. pots on the card might be all I need to adjust.
I've tried rendering tga to both frames and fields; changed cables and used 3
different monitors.

Carlton,
Don Landis is the Real Smart Guy on this subject. Since you seem in a hurry, I
thought I might offer some thoughts until Don steps in. (I asked Don about a
similar problem at Siggraph.)
Your situation is very likely to be a problem with signals getting into your
monitor from other monitors (turn all others off and see what happens) or from
the AC wiring. Make sure that all your video cables are not close to any
extension cords or AC outlets. Watch the screen while you move cables around
and see if the movement causes any variation.
One possible clue is that you say the screen "quivers" when the PAR software is
loading. Is your computer enclosed in the case? Is the monitor near the
computer? Try moving the monitor away from the computer. Try shielding the
computer with a 3'x 3' of aluminum (between the computer and the monitor).
It is very unlikely that the bars will show up on video tape — its probably
just affecting your monitor.

Hi Alec-
Thanks for the quick reply. In fact my cover is off the computer right now.
(I haven't hooked up a fan for the micropolis 1.6 gig drive, and I wanted to
keep an eye on its heat output.)
I will check your suggestions later today. However, gulp, (unfortunately), the
rolliing, scrolling bar does get recorded when I record the anamation.
I'll let you know what happens,
Gracias again,
Carlton

SHIELDING, WHO NEEDS SHIELDING? (VBG)
I think you called it right. I had time this morning to run by the office and
put the cover back on the computer, connect the monitor to the PAR output with
a 3 foot cable, and connect the monitor to the same AC power source.
I haven't laid anything to tape yet, but everything looks real good. I'm
hoping we've solved it.
Thanks again for your help,
Carlton
Hi Again Don;
Re: Par problem, I think Alec saved me.
