We decided to do a comp solution this time, the only way to manage in time but will still try and find out why it got all the problems so i know until next time i get the same problems. 

Thanks Shawn, will try that and see if it might help 

No had that problem at start so thats also fixed. It all follow the patch of the camera correct except that it is off, more backwards at the start and more forward at the end so almost feels like some kind of a proportion problem.

Thanks for the tips but unfortunately i have already checked the fps and its the same.

I have now however found a checkbox under the vue plugin in maya which said something about correct frames and it did make it a little better but then noticed in 6 frames spread out in the scene it flipped the camera about 180 degrees for some reason and a few frames before and after to correct the flip so did not help either. 

Nwm solved it.

Had to delete all in my vue-scene except the maya object, save the scene, open it in maya with the plugin, export the objects as obj, create a new maya scene, open my original vue-scene with the plugin, import the obj and the size and position was correct.

That was the solution to my problem! 
Thank you very much thd777, you made my day! 

cheers
