Well now,... I've put together a composite shot with several masks in place and I now need to provide a camera shake.
Here's the scene: we're on the bridge of a starship in battle,... shot in full lighting. I've gone in, for this short clip, and dimmed down the overall lighting, using masks to create up-angle "interactive" bridge console lighting on the actors. I have another mask in place to prevent the background readouts, on the walls, from dimming with the rest of the bridge.
The only thing parented to anything are two console-up-lit crew faces, which are the top layers.
How can I now add a camera shake without everything going out of register (which it seems to want to, when I tried it)
