Premiere Pro & S-Log3
Calling any Premiere Pro & S-log3/S-Gamut3.Cine Experts.
I recently started shooting in LOG (I know I’m late to the party) and love the dynamic range, but I’m not sure what’s happening in my Premiere Pro.
What I am expecting: I have a conversion LUT that I want to apply to all my LOG footage as a base (this specific one brags about its ability to give the best skin tones to S-log footage). In my head, I have my greyish footage in the timeline and I throw on the LUT in the Lumetri Color panel and adjust any minor parameters to fine-tune the shots.
What is happening: Premiere is automatically converting to Rec.709 and giving me a fine looking shot. I go to apply my LUT to the shot and as you expect, I’m left with a super contrasty shot.
What I’ve tried: The new Premiere Pro (Version 24.0) must’ve moved some settings around that I haven’t touched in a while, but in the settings tab in Lumetri, there’s a Source Clip section that allows me to throw an input LUT (same outcome as before). Under that, I can tick Use Media Color Space or Override Media Color Space. Use Media Color Space is ticked and gives me the default conversion LUT. If I change that to Rec. 709, I get my log footage looking like log footage and the LUT works as expected. BUT… Playing with exposures and curves on two very similar shots side-by-side (because I can’t use the same source clip in the same project to compare), I noticed that it seems that I’m not getting the same behaviour in my Waveform when adjusting the exposure. This begs the question: Is this method going to somehow ruin my footage and give me less flexibility or more noise, banding, etc.? It could just be that the footage just looks different because the LUT is different to whatever Premiere is doing. I’d just hate to be working so hard to get the shots, only to be unknowingly shooting myself in the foot in post.
Sorry for the long story. I’m hoping my ignorance is the only problem here. Any help would be much appreciated.
