# Move mask inside precomposition in After Effects?

(Asked by: username_0 on 2015-05-20)

I have a movie in after effects. I created a *color key, applied a simple choker* and then added a **mask**.

When I move the mask point, it is offset by the simple choker value - so I thought I would precompose the whole thing, so I can apply a second mask that isn't affected by the simple choker.

However, when I do that - the mask that was applied to the movie is not moved "inside" the precomp. It gets moved outside the precomp, and is **still affected by the simple choker**.

How do I solve this?
