Notes and Credits:

We wanted to acknowledge that Lumagen has a feature called Genlock which is designed so that the output timing exactly matches the input timing. However Lumagen says "Note that we recommend against Genlock for most systems since it does cause issues with some projectors and possibly some TVs" and also says "If genlocking doesn't work simply turn it back off--don't feel too bad as it is very hard for most viewers to spot a frame drop since they occur infrequently and a frame accounts for ~1/60th of a second."

We would like to credit Trexler Music/UKProjection for the use of the animated projector clip.
