ROTO BRUSH Distortion Bug
on Jul 13, 2011 at 8:22:28 pm

I have used the Roto Brush tool on a particular scene and for the most part it is excellent. There is one frame however that is messed up and I cannot seem to find the cause. There is a section of the frame that I am working with that gets mirrored and smear across the frame. I'm including a link but can't show the whole frame for copyright reasons.

Hopefully you can get enough info from the shot to see what is happening. Anyone see anything like this before?

I had the same problem and found that for me, it seemed to relate to interlaced footage / rendering out to interlaced. I changed renders to be non interlaced and if seems to have fixed it for me.

I don't think interlacing could be the problem as I'm working with Pro Res footage. This happens right in the composition as well, before I export anything.

It has something to do with the Decontaminate Edge setting. While on I get the smeared mirror and when off it is clean (but edges look bad).

I agree. I am using TIFF plates and getting the same problem. Fiddling with the decontamination settings can sometimes help.
