blender does not render path animation

Hi!
I move a camera along a nurbs-curve. Everything runs cool when I switch through the frames with the arrow keys. But when I render the sequence the camera just sticks to the position where it is in the 3D-View wereas other objects move the way they should. Any Idea anybody?

Hoping: Ulli

i dont know what could cause it, would you mind sharing the blend file?

Thanks for your help - meanwhile I solved the problem:
There was still an old constraint in the camera (it was tracked to an empty that did not exist anymore). As soon as I deleted the constraint everything worked fine! :slight_smile:
