I’m having the exact same problem. I have an Nvidia Quadro FX 370 card and Windows XP 64-bit. I’ve recently upgraded to CS4 and can no longer use Firewire out to a camcorder VTR and then piped from there out to my Sony monitor. VERY frustrating. I’ve used this exact setup before with no problems using XP 32-bit, and AE 6.5. Why isn’t XP 64-bit supported by Adobe CS4? Shouldn’t they know that most professionals are using 64-bit systems now? And obviously we’d like to continue using Adobe software.
@Guy Thompson, did you resolve your problem? If I have to install an extra card for video previews, I may do that to relieve my stress while trying to finish up this job. Any info on what card I could use for a S-Video output to my Sony monitor would be very helpful! But it should be compatible with After Effects’ video preview, of course. Firewire doesn’t seem to be an option now with XP 64-bit.
@Todd Kopriva, would you know what card to recommend for using video preview in AE to go out S-Video to a Sony monitor? Even if you can’t recommend one for XP 64-bit because it’s not supported by CS4, maybe you could suggest something that would work in XP 32-bit to give me a direction.
Thanks.
