4K HDR Encoding Setting

[ItsMe]

will be great if someone is writing down an step by step guide

No step-by-step but here are some pointers. May be someone else will make a video or write some step-by-step instructions.

Can everyone tell to me what is the correct 4K HDR setting in this program?

Correct HDR settings depend on the color grading parameters used for your content.
Typically you would:

• enable x265->Signaling->General Signaling->HDR
  
• disable the settings under x265->Signaling->Adjust color
  
• set the settings under x265->Signaling->Video Usability Information to the requirements of your source
  
• Make suer your set the x265->Base->Compatibility Restrictions
  

How can I  re-encode 4K HDR videos with x264 to 1080p?

In general you can load the source resize the source and reencode the source.
But since you probably also want to do a HDR->SDR conversion you probably might want to wait for the next release since Hybrid (then supports ffmpegs 'tonemap' filter which will be available under Filtering->ToneMap).

Because the preview script window can not showing properly the colors and the final encode will be an .... not good

That probably happens because you are doing a HDR->SDR conversion without tone mapping.

Thank You! I know it about this issues, but I thought you figured out how to solve it

Ok.
I have x265 CLI line for 4K HDR. Tested and working fine
I have tone mapped vapoursynth script. 
I have x264 Blu Ray compliant command line. Tested and working properly, sonic scenarist is fully approved.


My greatest sorrow I can not use these on my Mac, cuz all these stuffs are working on windows.

Only what I missing is a frame server like avisynth or vapoursynth.
I been installed the vapoursynth on to my Mac but I cannot figure out how can I use it. I can not load plugins, can not call in the ffms....so totally useless for me

Maybe an stuff will be great, what can handle easily the vapoursynth for the poor users like me. 


What I mean here: I downloading the plugins and what I want to use. Whit this program I can installing in to the correct place. Then I opening the script editor, and it is already to using to create the script.

Maybe u can make it to the part of the Hybrid, or just an single .....will be awesome!!

Can you make it to the part of the Hybrid, or just in the single application?

It will be very awesome!!
