Why is the Credit Roll exported from Motion 4.03 choppy?

Hi,


I created a credit roll in Motion 4.03. I've tweaked and exported it many times successfully. However, this time the QT was choppy. It's a SD project.

I tried exporting: current settings (NTSC Broadcast SD), Apple Pro Res 422, lossless + Alpha movie.

Computer:
Mac Pro 2.66 Ghz Quad-core
Mac OS X V. 10.6.8
12 GB Memory

Suggestions?

Thank you!

Credit roll in Motion is bad because it won't re-interlace

Sometimes the speed has to be certain multiples to look right in NTSC.
