I shot a scene the other day that had a lot of tree leaves fluttering in the breeze. If I use a Track Matte Key effect or cropping effect to limit the view to my head and shoulders, should I expect to remove the deteriorating effect the motion of the leaves would have in the exported file (causing the typical blur when you're using a lower bitrate)?
If not, how does unseen footage have the ability to affect the quality of the output?
