Arrrgh!
Added 2018-08-21 23:51:44 +0000 UTCOk so I am settling down to edit the raw footage I've got and realise that some of the clips have black backgrounds! it's at this point I realise that some were rendered as jpegs! I can't chroma out the background as all of the characters are wearing black. I've attached the raw footage it's all muddled up but I can't start editing until I render it all again, I have saved the animations so it shouldn't take as long. anyway take a look if you want and feel free to laugh at my mistake!
