Thanks!!

I made a screen capture to illustrate the problem:

You’ll notice at :17, after I scale the null object that contains my camera and my reference object, the camera suddenly jumps location.

This is related to a question I posted in the After Effects forum. Long story short, I’m trying to composite a live actor in a CG setting, and I can’t figure out how to match scale between my CG setting and my live actor in After Effects. Cinema4D isn’t allowing me to scale my “stand in” and my camera together so that my After Effects shot matches my Cinema 4D shot.

Thanks! Is there any way to establish the actor’s ground plane without using the 3D camera tracker? Because that’s not the method I used here, I moved the camera manually.

Also, though your workflow makes perfect sense – place the actor on the ground plane and scale the actor to fit the scene – I don’t understand where I would do that. What things are done in After Effects and what things are done in C4D? I’m going to take a wild ass guess below, tell me if this is accurate:

1. (AE) Key out actor
2. (AE) Convert shot of actor into a 3d object
– (AE) Establish ground plane for actor (How? Tutorial or link welcome)
3. (AE) Create camera and apply artificial camera movements to shot of actor
4. (AE) Export camera movements AND actor object to C4D
5. (C4D) Import Camera information and actor object (for reference) to C4D setting file
6. (C4D) Create null object, put camera+actor in null object, move null object to desired location
– (C4D) Scale camera using actor as reference to the desired size
– (C4D) Once at desired size, delete actor reference
7. (AE) Import C4D setting into AE, place C4D layer under keyed actor.

Is this right? THANK YOU!

I’m having this same problem and the opacity change isn’t working. The only thing that works is quitting Premiere and re-opening it, but doing that after every edit would drive me insane. Anyone have any more ideas?

I only have Cinema 4D Lite, the kind that comes with After Effects, so the only way I can access Cinema 4D is through After Effects. I imported it by right clicking the project and selected “MAXON CINEMA 4D FILE” and then building the project, it connects automatically.

Worked perfectly thanks!

THANK YOU! I’m in another project right now but when I’m back into that one I will check this out, thank you so much.
