PremierePro Override Media Color Space Problem

Hi everyone,

for a while now I’ve been running into a problem with Sony S-Log footage in Premiere Pro.

My usual workflow was:

• Import Sony S-Log footage

• In the Project panel: right-click the clips → Modify → Color

• Enable Override Media Color Space

• Select Sony S-Log3 / S-Gamut3.Cine

This always worked fine in the past and immediately converted the footage out of the flat log look.

However, this no longer works at all:

• The override is selectable, but nothing changes visually

• Even if I intentionally choose a completely wrong color space, there is no effect

• Restarting Premiere, new projects, different clips – same result

So it seems the Override Media Color Space is being ignored entirely.

Has anyone else experienced this?
Is this a known bug or a change in Premiere’s color management?
And if this function is broken now: what is your current, technically correct way to convert Sony S-Log3 to Rec.709 in Premiere Pro?

What confuses me most is that I can barely find anyone online describing this exact behavior.

Thanks a lot for any insight.
