Have effects go over the bounding box for the clip they're applied to

[markwm]

I don't really know how to explain this but let's try.

I have a project 1920x1980, inside this I have a placed a movie clip on the timeline that is 200x200. I have a applied a lightning effect to this clip.

My issue that that the lighting is contrained within the 200x200 area of the clip, is there a way for it to overspill this area?

That's where you pre-compose the layer to a larger composition and then apply the effect in the parent comp to the now comp-sized layer containing your other elements. As an alternative you may be able to use the Grow Bounds effect to some extent, but it has limits in how far it can expand the boundaries of a layer. That's why I would suggest you actually spend some time learning about the benefits of pre-composing. It's an essential AE technique and useful and necessary to solve many problems and structure your projects.

Thanks, this fixed it exactly. I'm new to AE.
