Empire and Jedi should be finished in less time. I'm using one setting for all frames now, so in principle that should also work for Empire. Jedi may take a little adjusting, but I suppose that should not be too much work. The rendering now takes ages, though. Once the video sample is finished, I will render Star Wars completely, if the sample looks good, an will do Empire immediately after that.

I don't think that video would work, as you need common elements in the frames, and in this case the elements are averaged with elements from the other movies that move in a different manner.
