Choppy playback video with keyframe animation

Hello!
Hope anyone could help me on this. I have edited a videofile in fcpx. it is made of pictures/objects/text that have been animated using keyframe. Some of the elements have been made to compound clips.

When exported out it is playbacked choppy. I have tried exporting in several formats without any help. Anyone now whats causes this? (See attached file) I want the animation to be super smooth.

The video

Specifics? Duration, frame size/rate, codec?

The total duration of the video is around 2 min 10 seconds. The codec is H264 and the framerate is 25 FPS

Can't see the choppiness in the little snippet you posted.
Are you sure it is not a playback issue in your mac? Try it on different machines.

I have tried it on many machines, and i see almost the same on all of them. Full length video can bee seen here on Vimeo: vimeo.com/121295851
It is more choppy on windows machines than mac machines.

Clicking the link to your full length video reveals this:
Sorry, there is no video here.
Either it was deleted or it never existed in the first place. Such are the mysteries of the Internet.
