Gamma shift !!how to fix it??

PostTue Mar 12, 2013 3:52 am

hello guys when I render my project(DaVinci Resolve) I got a gamma shift, this gamma shift makes my grade looks really bad. I will post a screenshot later.

What is your final delivery? Does it look okay there? QuickTime player is notorious for showing wrong gamma, but it's possible the encode is actually fine.
Also - it's pretty obvious, but I'll point it out here again: you need to be monitoring with a calibrated monitor in Resolve, not goodie GUI computer screen.

Well, I think the problem is the quicktime, Qhen I open my rendered file in davinci it looks just the way I grade, in quicktime it looks terrible, yellowish. Well thanks for the quickly answer

There was a link not to long ago re limitations with ProRes plus test results.
Not sure which post. Very similar problems.

do a simple test: render 10 dpx and look at the in photoshop/any other software (Nuke, AE) and see if you get any shift.

I think is the quicktime encoding...
