[Frameworks] Traditional Rotoscoping Mirror Problems

[Christopher Ball]

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
