Can I make a "snapshot" of a layer and work on that rather than duplicating a layer in order to avoid rendering effects twice?
I have a layer with lots of effects. I want to make an inset of this layer; a circle with a zoomed in detail. The problem is that if I copy the layer, apply the same set of effects, increase the layer scale and apply a mask, then rendering the composition is twice as slow as all the effects are rendered twice; once for each layer.
I was hoping there might be some way of creating a "snapshot", or "reference" to my main layer, since all I want to do with the copy is increase the scale and apply a mask.
I am aware that I could render the layer, then import that as a new piece of footage to use as the second layer, but this seems a less than ideal solution.
Is such a thing possible? Does anybody have an alternative approach to achieve the same thing? Or am I just going to have to put up with the long rendering time?
