I am getting mixed results from rotobrush. I can't seem to get the refine mask functions to work when using the rotobrush on a particular set of clips. It's some very low quality footage that started out as DV, and was resized to 720p. It looks horrible, but the rotobrush has managed to detect the edges very well. Only problem is the edges are pixelated and noisy. I can't get any blur even when I try the refine matte, reduce chatter, and decontaminate. The feathering of the edge shouldn't care how bad the footage is.
I tried another clip from another project and it worked much better. It edges feather nicely. Both clips are DVCPRO HD 720p60. I can't figure out how to make the first set feather. Any help would be appreciated.
