XDCAM Artifacts for chroma keying.

Hi guys, i'm having a bad week. First, allow me to illustrate:

7157_cocineritostortasblasoliviaycata1.01.44.15.png.zip

I've been handed some XDCAM for chromakeying, and as you can see, the quality is reaching OHGODWHY levels. There's heavy artifacting, and the chroma is severely underlit, and as you can see, it's practically yellow. The kid's elbow will have to be rotoscoped.

I've been having mixed results with Primatte, specially with shadowed areas; and absolutely lousy ones with keylight. What methods can i use to make this work? Or is this beyond saving? Are those artifacts inherent to XDCAM, or has some ball been dropped along the way, during conversion or something like that?

Thanks a lot!

If you file a "bug" using this URL: https://www.adobe.com/cfusion/mmform/index.cfm?name=wishform

I'll look into it and might be able to help you get a decent key.

Oh, i got that, donĀ“t worry. I'm just glad not everybody just watched the png and ran away screaming in abject horror.

Done! I just sent it.

Sadly there are a lot more takes than that one, with varying qualities of illumination of the chroma, but a solution to at least that one will be illuminating. Primatte ended up saving the day on some cases, after some heavy, heavy tweaking. Still lots of rotoscopy neccesary. Again, thanks for the help.
