I'm brand new to using Particle Illusion SE and having a problem with the output AVI file I'm creating. The original video plus the particle effects I have added only fill the lower right quarter of the output video. The top half and right half of the video are black.
The input AVI, my stage size and the output AVI are all 720x576.
I tried this with Hardware Acceleration On and Hardware Acceleration Off.
Do you have any windows on top of the particleIllusion window when it's rendering? Sometimes that's an issue (with some video cards or drivers). Make sure pIllusion stays on top and don't move any windows on top of it while rendering.
