Buy LUTCalc and roll your own... Very simple and very useful utility.

It's only for log...I need something for Cinema4 / s-gamut. Any suggestion?
Hmm,
I'm no expert at all and haven't used those exact settings, but I did use Cine 4 with pro colour. I found that crushing the blacks was a good place to start. I didn't use a LUT. I only use Casey Wilson's LUTs for SLOG 2 shot stuff. But for cine 4, I think you should just be able to grade from scratch.
I assume that you are shooting low light/night time stuff if using cine 4?

Unfortunately there's no curve in LUTCalc for Cine4 but for Cine1 (HG4 or HG4609G33).
You need to build a temporay LUT like SL2 => HG4 and then use the LUTAnalyzer to have HG4 as a recording gamma. Then you can build a HG4/S-Gamut => HG4/709 LUT which should get you fairly close. Wouldn't use any other target gamma in that case though, since the input gamma is not matching properly!

Another option would be to linearize Cine4 by hand, apply the color matrix to Rec709 and then go to you preferred gamma. Can be done in Resolve for example.
Hope that helps!
