C4D-How to make the Video to follow the screen?

Hello all
Sorry if this question has been asked before but
Let’s say we have a 3D Computer in C4D ,a camera that moves around it,and we want it to export it to AE and let the user replace the screen with his Media.
How can we make the Placeholder to follow the screen in 3D Space?
Thanks in advance

I’ve already checked this tutorial,but this guy has exported in AE this “Screen” Solid,I don’t have anything to replace with ALT drag n’ drop.I just have the .Mov files and the camera.

Adjust the settings in the External Composting tags in C4D .

For once again,Felt rocked Thank you pal!

And lets say that c4d rendered video (or image sequences) is below plane layers in after effects. So how to make other side of planes invisible?
I hope you understand what I mean.

I think so….

Use a composting tag to render out a separate object pass and matte the layer through that.

Alternatively, you can turn layers off that are facing away from the camera with an expression in opacity….

(toCompVec([0,0,1])[2] > 0) ? 100 : 0;

Thanks! I’ll maybe ask more questions when I try.
