QTs are washed out when rendered.

HI there

I'm rendering out through AE (v12) and through numerous codecs - animation,H264, ApplePro, tiffs, etc.... - and all QTs look washed out when compared to the AE project. Does anyone have a solution or know the cause of this? (OSX 10.8.4 & GeForce GT650M)

Any help appreciated.
