Waves.... ugh....

[bgrieb]

I have a 20 foot composite cable running across the room from my Satellite receiver to my capture card. My problem is that I'm always getting waves across my picture when I capture (or watch TV on the PC). The waves are not really bad, but they're there none the less, and they annoy me.

I've tried S-Video cables and had the same result. Needless to say, when I watch a TV Set connected to the same receiver with the same cable, the picture is clear. I've made sure that the cable does not cross (or come within about a foot) of any power or data cable except for when it actually departs the Satellite box and again when it actually reaches the computer. At those points, I've tried to seperate it as much as possible.

What gives? Is 20 feet too far to run a composite cable? Is the computer just more sensitive to possible line noise? Is there a way to fix/reduce it? If not, what's the best way of trying to filter it out during the editing process?

Thanks for any help you can provide.

I had a similar problem and eventually gave up and bought a video sender. Money well spent!

you have most likly, a ground loop (ground potential between two pieces of equipment is not identical) .. use a video ground loop transformer/isolator

like part number VB-1RR on this page http://www.jensen-transformers.com/iso_vid.html


or you could try to plug your all your equipment in to the same electrical circuit .. also make sure all your power cables are pluged in w/ the hot and neutral the same way (as in correctly)..
