I have an AE project in which camera is parented to a NULL and both Camera and NULL are key-framed. Is there anyway to calculate the effective camera value or is there anyway to recreate the same camera movement but without a NULL.

Thanks

Here's a script for baking AE camera data.

Nice script!
Just for an alternate take, you can also reference a parented layer's actual place in AE's world with expressions.
Parent a null object to the camera's null and then change its position to match the camera's position. (This places it exactly where the camera is.) Now parent the new null to the camera. Now it will be exactly where the camera is at all times. (Title it something like CamTrack_NULL.)

Then, if you want something to reference the camera's actual position in AE's world, put this in:

L=thisComp.layer("CamTrack_NULL");
L.toWorld(L.anchorPoint);

I forgot to mention that there might be a way to directly reference the camera, but I don't know if off the top of my head and my brain's a bit fried today.
