S-Log files automatically have a colour profile since the update

I did the colour grading for the S-Log shots in an older version of Premiere Pro. Since the new update, the colour is no longer correct and the contrast is much too high. It looks like Premiere Pro automatically selects a colour profile for S-Log. Unfortunately, I can't find out how to switch this off in the new Premiere Pro version. Can anyone help me?

Following the links Ann provided, you should be able to find the new color management settings in the bottom of the Modify/Interpret Footage panel. Rather hidden to my mind, but the devs think that's the logcial place everyone would naturally look to ... ahem.

They have the tools there, and there's both the "override" option and an input conversion option.

The totally non-intuitive thing is if you use the Input option, that's only to tell Premeire what you want that to be 'seen' as on input.

For proper use, meaning display and output, you ALSO need to set the Override to option to what you want done with it.

So ... setting the S-log3 option in the Input isn't enough, you also need to set the Override to Rec.709 option.

Cheers R Neil Haugen!
This was really helpful it worked. Initially I spent lot of time trying to figure this out, checked all the options available, including interpret footage. Maybe putting this option under interpret footage is alright. But it is confusing when they say "Use colour space from Slog3" and then it gives you colour corrected view. Why would I click on "colour override" when I have already selected "use colour space from Slog3".. there liew confusion. Still not able to figure out why Adobe felt the need to make this change..

Full user controlled color management, like Resolve has had, will have several steps.

The first is stating the assumed color space of the file entering the CM process. The next is any tranform/conversion to bring that file into relationship with a sequence. Then there's the Display CM setting ... and of course, export.

So as Premiere Product Manager Francis Crossman, you may well be best served by both checking that middle option of S-log3.cine (to set the Input transform) and the Override to Rec.709 to set the sequence space.

Or not ... you'll have to test on your system.
