Are you doing the whole film, or parts of it?
Does the film actually play in the film viewer?
Are you trying to use any custom camera setups/shots?
One thing, if your video card runs out of resources, then all bets are off. How much video RAM does the video card have, and what graphic details do you have checked in the game?
Sorry it took me awhile to get back.
I'm trying to convert a 50 second clip that I had cut from a larger film recording.
The Film itself does work without issue In the film viewer.
Originally I had a camera angle set to follow behind my plane, but the issue comes up even when I leave the camera angles alone.
I don't know about how much RAM the video card has, I know the machine itself has a 4gigs. Graphic details are set to what I play in game, which is relatively low with no anti-aliasing and only map bump and detail terrain turned on.
