I am trying to convert a bunch of HDR movies into SDR using “TMPGEnc Video Mastering Works 7” which allows the use of LUT files and I was wondering if there’s someone here willing to help me out.

I have successfully imported the “Rec2020ToRec709_CSTDefault” LUT file, which I suppose is the one to use, and the results are good, but I’d like to make them better, but I’m not sure how.

Thank you.

The conversion LUTS (HDR > SDR) generally are fixing the overall overexposed and washed out look you would get without correction. The issue is that one LUT will not adequately correct every scene in a film. Each scene has different light and color, so to achieve good results you would have to color correct scene by scene, ideally using an NLE.

Adobe Premiere has a built in “SDR conform” tool, and while you can apply it to the entire video, you can also create an adjustment layer and tweak the SDR conform settings scene by scene.
