Has anyone experienced this very unusual error with the Decklink SDI card?
In After Effects applying a "generate fill" effect (default colour 255/0/0) to a full frame solid or creating a new full frame red solid (255/0/0) causes the computer to crash hard. The grey window shade comes down and the computer can only be shut down with the power button. Creating a solid of any other colour is fine. Creating a small solid and making it red is fine. Scaling that small solid up to full frame causes the same crash.
The reason I think that it is related to the video card is that the error does not occur if video previewing is switched off in the AfterEffects preferences. Its almost as if the card cannot cope with a full frame of red.
