Are you using hardware MPE/GPU acceleration? If so, you have to turn that off before you can view output over DV. It's a known issue.
I don't know if i am using MPE/GPU acceleration.
I have an Dell XPS 9100 Computer.
24 gigs of ram
Quadro 4000 graphics card.
I figured that if CS5 had all the requirements. Mercury Engine playback, rendering would just be screaming on this machine. It works great, Multi layers of video seem to take a bit longer to render, but no video through the deck and on my ext hd monitor.
it was once there, now it is gone. I have updated PPro with all the updates.
Go to Project > Project Settings > General. Check the "Video Rendering and Playback" section; if you're set to "Mercury Playback Engine GPU Acceleration," change it to "Software Only" and try previewing through DV again.
Mercury Playback Engine GPU Acceleration
what is the difference between the two? Isn't the GPU acceleration better?
it worked. thank you. but it worked with the GPU acc. before. could it be that the Ppro updates affected it or maybe the graphics card?
