Hasta La Motion!

Keylight is rendering stray lines across my keys.

Ive attached a grab of the alpha on one of these.

I’m using prorez 4444 files from the alexa. Though I tried converting these into other formats and I still get the same issue. Edit ( I just tried this with some other sources and im still getting it) Also this is nuke 6.1v3 and keylight 2.1v6

It also doesnt happen consistently, sometimes it will sometimes it wont.

It also changes when i change anything above the keylight and it rerenders.

I need to use keylight for these because I am using several artists who have just moved from AE and dont know anything else. Does anybody know what the issue is here??

THANKS!~!
