isolating a an object in the background

Hello guyysssss! So I am working on this camera shake movement, basically i have this image of a window looking out to a town, i added the camera movement to shake it, but it shakes the whole thing,  i don't want the image from the window (the town) to shake. How do i go around that? Basically its this image

Thank you!

if you move the camera this means all layers that are 3d will move along with it. if you want some layers to not be affected, you can instead use a null and connect your layers to a null and shake the null.

BTW it appears you are using rotobrush on a still image and you wouldn't want to do that. you should cut the image in Photoshop if it's pixels and free up some memory for Ae to deal with processing the animation.

Ahhh, I see what you mean Roei, but that image is a whole layer, with the outside as well. I do want the inside of the room to move but the image outside be still. Yeah, I might try cutting it in photoshop actually, Thanks!

Yep you can cut in photoshop If you want them to move separately. You will need to place the window and room layer above the outside layer and complete additional background for the outside so when the room moves, it won't show tranparent/background color where the layers move from each other. Some effects can be used to extend background like motion tile and CC repetile. or just do this in Ps.
