Ive created a character and wanted to export a transparent video. Ive chosen the pro res 4444 format and even attemped to use super sampling thinking it would help, but when I get to watch my video, I get a strange green edge around my character. 

this is what the edge looks like on CTA


This is what I'm getting after the export . 



has anyone encountered anything similar, and could offer a solution? Could it be that my edges are blurred? Would a png sequence fix the trick? I know png would fix this issue, but I'm hoping there may be a way to get this working with out a png sequence as its a dance sequence and I want the audio to match up in my final edit in a third party program.
