The camera is a better way to go. If you have a flash head (A Strobe) it will give better results frame to frame than that light source. It will also freeze any motion in the frame and give you a really sharp picture.

An old non-digital 35mm camera can be cannibalised to make a film gate, good SLR bodies are basically free these days and a great source for parts.

Thanks for the suggestions. Can you explain the flash head idea further? I have a Canon Speedlite flash, but I am not sure how it would be used. Would I bounce flash it off a white surface, or disconnect it from the camera body somehow and fire it directly through the film into the lens?

I think the light source I have is pretty good and will hopefully be consistent. It has lots of LED's in it evenly spaced, and placed far enough away becomes out of focus so you don't see any of the individual LED's. I always do a full scene from start to finish before taking a break, so it should stay consistent for short spurts I think. I will know after I build the rig to run the film through how well it performs. The brightness is adjustable, but as long as I leave it alone for an entire scene, it should stay the same hopefully.

I am also interested in the 35mm camera film gate idea. Do you have a link or any suggestions about how to go about that? I have my own ideas what I plan to build, but it may or may not work well. I will know after I try it. I plan to work on it this weekend.

Thanks again!
