I shot the whole thing on ones, at 24fps. Then I took it into After Effects and used the "Timewarp" function. I set the Speed to: 100 and clicked "enable motion blur." Made it "Manual" and set the shutter angle to: 275.04 and changed the shutter samples to 11.
This method (which I believe is called "Megamotion") was first brought to my attention by Peter Montgomery from a post he did in the StopmotionAnimation.com Handbook.
Of course the technique I previously described is slightly different from the one in the handbook. I can't find where I originally got that info, but I know it's based on it... Anyway, thank's to Peter Montgomery for figuring this all out!
More stuff on the way.
