I have been trying for weeks to do this 3D glitch effect in After Effects. I am new to working with expressions and Z-Scale. I am using a 3D camera tracker to create nulls to show in what parameters I can make the glitch in. Once I did that I have to dublicate my clip and freeze frame it. After that, I type in the expression zoom=thisComp.layer("Camera 1").cameraOption.zoom;
and turn it to a 3D layer to make the Z-scale fit over my original clip. Every-time I try to do this, it gives me an error and doesn't fit my freeze framed clip to my comp. I posted the 2 tutorials on how to do this and if anyone can get back to me and let me know what I am doing wrong, I would greatly appreciate it.
