3D object not showing in render of camera tracked scene

Good afternoon all,
I have a problem with rendering a 3D object over a camera tracked clip. The 3D object does not show up in the render. Only a frame from the clip renders. I have checked the scene tab in the properties editor and the layers that the objects are on, but everything seems to be in order, and changing which layers are masked does not make any difference.

Here is a screenshot:


Any help would be appreciated. Thanks in advance.


Insufficient info. Remove all the unnecessary crap from your blend file and attach or post a download link to it

Ok. No problem. Here is a link to the blend file:


If someone knows what I’m doing wrong that the cube isn’t showing in the render, please tell me.
