Hey Guys,
So all of this has been working great! Thank you so much for the values of their c-log curve. A huge help. The workflow works all the way until I try to write back out xdcam 50mbts QT files to send it back as source material. I get a gamma shift. But when working with dpx's generated from that source QT, color is preserved all the way through. Anyone have experience with the xdcam codec causing trouble? I pinched the codec from the trial build of FCP to even read the files in the first place. Thanks!
