On some of the effects with a reduce chatter-feature available (like the Roto Brush and Refine Matte for example), there's almost always an option to choose between two different methods to reduce the chatter: "More Detailed" and "Smoother (Slower)".
What's the difference between these two methods, and which one is usually the go-to?
chatter reduction should be done very carefully in Rotobrush refine edge matte or refine soft matte. I sometime have to leave it off because it introduces artifacts that are much worse than the chatter. in all the years I have used this feature I can't say there is a preferences - simply compare the two and see which one gives you the best result over the duration of the effect.
