Our AE artist is working a session with clients and is unable to get his RAM Previews to playback in real time when mirrored onto a client plasma display. He is working on an Intel-based Mac Pro, signal to the plasma is run to a DVI spliter using the second VGA output on the back of tower.
So far, we've found that when "Preview"/"Mirror Computer Monitor" is enabled under the "Video Preview" settings in Preferences -- the RAM Preview will playback on the plasma but at only 20-22 fps (comp is built at 29.97). When "Preview" is disabled, RAM Preview plays at real time on the Mac Pro but no playback on the plasma.
Is this an issue with our video card? A setting in AE?
Any thoughts or help would be greatly appreciate...
