[HELP] How is the video with color rec.709 change to rec.2100?

[tauri141]

It really turns out as Shijan says. But with the help LUTCalc tool I was able to achieve a result that is more or less suitable for me. And using Filtering->Vapoursynth->Color->Matrix->TimeCube-> Custom LUT (Before saving from LUTCalc SLog3_SonySGamut3_v2cineVenice-SLog3_SG3c_v3.cude) Make the output file as gray as I need.
How can I do it all on the command line now. In order not to launch the Hybrid program interface, but to register all these actions in the command line. So that can only change the names of incoming and outgoing files.
