Credit Rolls.. How do I get the credit rolls to look good? FCPX and Motion5 I use Motion 5 to create credit roll export. 
It just looks awesome. THEN, I import it into FCPX and after export, it looks jumpy. 

Does anyone have the golden tip? I've heard about Motion Blur.. tried it.. didn't do the job. I'm beginning to think that I have to export the file without credits and import into Motion 5 to attach the credits and export again.. 
(Haven't tried that, but a .mov from motion works)

Appreciate the input.
it looks jumpy


Most probably you have mismatch of framerates between Motion 5 project and FCPX. Check if they match. Also check all other video settings, to match your FCPX composition.
