h264 export colors washed out with compressor and QT7

Hi there,

I've been looking over the internet since 4 hours now and i can't find one single solution for my problem. I'm trying to export HD DPX files with compressor to turn them in h264. I've played with the different settings (gamma, color filter, brightness, contrast) nothing is working right. I've also tried exporting in pro res 4444 then compress with QT7, but it's still the same washed out image.

Can someone help me ?!?!
