According to Blackmagic wesite:
“Unshielded graphics cards should be avoided when using a PowerMac G5 and a DeckLink card with analog connections. Unshielded AGP graphics cards have been found to cause electromagnetic interference with nearby analog components and this can lead to the output of interference patterns in analog video.”
I had always have problem with such interference with my G5 (always have to explain to client why the video is flicking), now that I am going to upgrade to MacPro, I would like to know if the “ATI Radeon X1900 XT 512MB SDRAM” for MacPro graphic card an Unshielded graphics cards?
The “NVIDIA Quadro FX 4500 512MB SDRAM” option is just too expensive for me…I mean if I had to spend another US$1650 on this option, it adds to the value of the BM card, then I might as well consider other capture card and not just BM card that is no longer lower in price vs quality because the true “cost” has went up. Unless of course other card also face the same issue.
