It sounds like you need THREE layers:
- The foreground subject
- The middle-ground subjects, the ones with the arms
- The background
The first two layers mentioned would be shot on green screen. But it sounds like you only have two layers. Is this true?
- The foreground subject
I did try to create three. I have the background. I shot the subject with arms, then again with the arms behind the back to try to similate having no arms, but we did not shoot very well, so it does not match up so well. So yes, I do have three layers, but if I decide to not use the one with arms behind the back, can I duplicate the top layer twice, mask the first, then paint over the arms on the second?
Of course we may decide to reshoot, so that is always an option. Thanks.
You could try to salvage the shot by animating a garbage matte to isolate the arms once you pull the chroma key, then animating both layers' position properties to get things to match up. It'll be tough to do, I think.
If that doesn't work, take what you've learned about the proper way to shoot this, re-shoot and try again. You will have gained valuable experience.
I have definately gained valuable experience. No doubt about that.
So do you know a way to get the Ultra Key I did in Premiere to show up in After Effects? Thanks
A screenshot of the footage would help us focus a little better on a viable solution.
Here is a screen capture. We have been talking it over here internally and I think we are going to reshoot. We are going to treat this exercise as a rough cut and use it as a story board to get the reshoot correct. I appreciate the help and suggestions. It may be a few weeks before we get to shoot, but I will try to post back when we make progress.

With this complex of a key I'd do it all in AE. Keylight will go a good job.
You'll need to be very careful with the positioning of your actors so that the arms don't overlap. If you want overlap then lock off the camera and shoot one shot with one actor and another shot with the other. This will require a bit of planning and some good direction but it will be easier in post to separate out the elements.
Once you have the shots first thing you'll have to do is to pull a clean key. Once the actor is keyed perfectly duplicate the layer and roto out the actors body so you have one layer with just arms and another layer with the arms and the rest of the body. A quick mask around the body will be much easier and faster than trying to cleanly mask the moving arms. Just set your mask to subtract. You can then do a simple fade from the arms only shot to the entire actor shot.
I hope this helps. Planning is the key.
Thanks for the reply. Very helpful. I will keep you posted when we reshoot. Just getting into After Effects. Very cool stuff. Very powerful.
