Animations export in mov to FCXPRO - bars and strange effect

Hello,
I produce movies with Motion 5 animations. I export animations from Motion, import to FCXPRO and try to export in current settings. Final in this part, when I've got animations I can see some bars and strange effect - I think it's something with resolution. Then I convert with iSKYSoft to avi (for clients needs) and this effect is stronger. Can anyone advice me?
