I had a different set up than yours, so not sure if it is applicable. I projected the prior frame of 35mm film through a lens, then to a mirror and back to the next frame of film. I could not get it in focus until I added an aperture at the focal point of the lens. Then it came in sharp, though there was a loss of light of course. This probably won't apply to you as you are using a computer projector
