Continuous Rasterization

Does anyone if there is toggle to collapse transformation and continuous rasterisation like in After Effects?

I've not looked at AE for a few years now. How does that work, what is the purpose?

FCPX does not have a toggle but will continuously rasterize elements nested in compound clips. I've done nested zooms where I've scaled huge pieces of art into compound clips and then pushed into them from outside. FCP unlike AE always continuously rasterizes because it's built on a modern AV foundation that uses all of the graphics card. AE has a toggle because it's built on legacy code and hardly touches the graphics engine. In the past, having continuously rasterize on all the time would totally bog the system down, so they gave you a toggle. FCP doesn't really need the toggle because I can't think of why you'd want to turn it off if it doesn't create a performance hit.

I think you just need to make sure you render at the "BEST" setting to make sure things are continuously rasterized on export.

I did some digging. If you are using vector elements you can check fixed resolution in the media inspector. This solved my aliasing on the edges when scaling.
