Thanks.  I used JS DeInterlacer (for the Mac) to do the fast-motion effect.  In my opinion, it's better than iMovie.I do have a high-res version, but, unfortunately, I don't have the bandwidth to host the file.  Truthfully, I think the low-res is better.  Something about low fidelity makes the back-and-forth camera motions more tolerable -- less likely to throw up while watching it. ;)
