I didn’t mean I do layering this way, no. I just made an example out of a simple project. The only reason I would put text in a layer and then scale it, is because other stuff need to be in the same layer too.

To clarify myself:
Does Motion use a buffer for each layer? (meaning that every time i use a new layer it loses quality on a scale or half-pixel-movement)
Is what is missing from Motion concatenation? (I remember this from Shake)

I thought at first that Motion just takes ALL the parameters from ALL the layers and summarize them to render vector content (like text) instead of going a layer up every step to make a render. I believe that sequential rendering (or how the hell this is called) is a huge disadvantage of a compositing software like Motion (if it applies of course).
