Question

Cinema 4D camera tracking asynchronous to After Effects

Hello everybody,

I have a problem with the placement of a 3D object in After Effects - if I create a colored area at the desired position after 3D tracking and use it to watch the video, then everything fits.

Then I did a C4D export, placed the 3D object and imported the file into AE. The tracking shakes in the C4D file much more .. is asynchronous to the AE tracking. Do not understand why.


The front slightly lighter colored area is the offset of C4D. Here the exported C4D file is simply imported into AE without touching it.

You have to match up the cameras and the coordinates. If you don't establish an origin and ground plane and set a reference solid at the same point, or you don't export a C4D file from an AE project with a camera, it is nearly impossible to match up the C4D coordinates with the coordinates in After Effects. 

 

If I am using Camera Tracking I will always export the AE Comp as a C4D file first, then import the file, use the Centered Comp Camera in Cineware and go from there. Most of the time I also re-center the Camera Track so that 0,0,0 in C4D is comp center in After Effects.

 

Sorry, don't have time to point you to a tutorial on how to do that or list the steps here, but it takes a lot more work and preparation than just adding a C4D file.

Impossible to say. No offense, but cropped screenshots are utterlky useless. you would have to show us the actual comp and timeline in AE, your scene in C4D, your tracking results and parameters and so on. Judging from the extensive pixelation this could be a scale issue with your screen area being tiny and AE therefore calculating a camera with funky values and a long focal range that will be hyper-sensitive to even the slightest change in position, but it could of course just as well be anything else like messed up framerates or setting a wrong resolution in the C4D render panel/ scene setup and then getting bad alignment. We simply can't know. You have to be much, much more specific.
