Slog LUT with weird color problems, only in Premiere Pro

[timos11067057]

Hey guys,

I have a problem with my slog2 footage (slog3 same error) when I want to correct it with a tpyical LUT from slog2 s-gamut to rec709. I tried a lot of LUTs, the official ones from the Sony page and others as well, every time the same error. As you can see in the screenshot, there are some strong, in this case yellow, color streaks all over the picture. The blue channel in the RGB parade looks weird as well, as I have never seen anything like that before.

When I adjust all the parameters by myself in the lumetri panel, the picture is also fine. It's only a LUT problem.

At first I thought my camera (Sony Fs5) is the problem, BUT, every other NLE can handle the LUTs just fine, it's only in Premiere Pro. Davinci e.g. had no color errors.

Is there a solution for that?

Here are some details about my footage:

Recorded on a Sony FS5 M1

XAVC-L, 1080p, 50Mbps

Slog-2, S-Gamut / Slog-3, S-Gamut3.cine

Same at:

XAVC-L, 2160p, 100Mbps

Slog-2, S-Gamut

My Premiere Pro Version is 13.1.4 (but I had this problem in earlier versions as well)

Thanks!

Davinci [Resolve] had no color errors.

Not quite the solution when you don't want to switch platforms for grading.

But a little update on my error: I tried everything on another computer and everything works fine in Premiere. Looks like my Premiere Pro is damaged somehow or some of my hardware components (AMD Radeon R9 280X maybe?) are the problem.

If it works on another computer my guess its hardware.

I got it! My Mercury Playback Engine was set to "Metal"...switching to "OpenCL" was the solution. Normally this is what I choose in every project setting, didn't think about that for one second.

I guess we can close this discussion

I have the same problem but changing the Playback engine from Metal to OpenCL nothing change
