Gamma 2.2 vs 2.4 - Gamma shift on export - WTF Adobe.
Hi.
We've been on this problem for quite some time and it has come to a community post. If there is a neat workaround, it is very welcome. But please fix it in the next update, adobe.
Problem :
The problem is a gamma shift on export from premiere.
In general when coming from grading, we'll receive a 422HQ with gamma out 2.4 as it is the standard.
The fromgrade looks like this:
inside premiere (program window) it matched perfectly :
Now when exporting the gamma 2.4 from premiere there is a clear shift :
For testing we exported the grading with a gamma out 2.2 from resolve:
It matches perfectly with the 2.4 export we just did.
So the 2.4 shifts to 2.2 on exporting from premiere , which is very annoying.
But there is more. Put the 2.2 gamma in the Program monitor and you'll get this :
a shift from gamma 2.2 to 2.4
Exporting the 2.2 from premiere :
It does what it has to do : the gamma remains 2.2
Conclusion :
When inside premiere you'll work in a gamma 2.4 on the programviewer & source.
When exporting it will be a gamma 2.2, no matter what you do.
Solution :
I know there is a lut that is supposed to fix this. But it does not. It's a lut.
So at the moment the only solution is to grade in gamma 2.2, that way at least the colors will come out the way the grader & DOP wanted. Or maybe there is a solution I don't know.
