I have a 4K timeline using the S-Log 3 LUT and some other minor color corrections, and when I send it over to Media Encoder the LUT is being dropped and the final video looks just like it did coming straight out of the camera.
Has anyone else experienced this issue? And what was the fix?
If on a Mac, try copying your custom S-Log 3 LUT to the Media Encoder / Contents / Lumetri / LUTS folder. Go to Applications and Right click on the Media Encoder icon, show contents, then path to the folder and paste your LUT. Media Encoder should now see your LUT when exporting. Be careful doing it this way as some custom LUTs are not supported and can lead to odd behavior with your Adobe applications.
Additionally, you can add your S-Log 3 LUT through the effects tab of Media Encoder's export preset setting so it points to the LUT properly.
