I see a lot of posts about flicker in the captured video. Most successful transfers involve speeding up the projector slightly and using a high shutter speed on the camcorder.

I am a bit confused at how these 2 are related. I have heard that the 18 fps that Super 8mm uses is the slowest you can go with noticeable flicker. I can see why speeding it up playback would help. What is using a high shutterspeed going to do?

Now, the hard part. My projector does not have variable speed. Am I up a creek?
