ACES: C4D to AE to Youtube HDR

Hi

I'm trying to render ACES in C4d. Import into AE. Export in an HDR format I can use on Youtube. Goal is to have Youtube show the same as i see in the Redshift render.

I'm almost there, but I can't figure out how to do the last step correctly.

This is what I'm doing so far:

I render in c4d in ACEScg 32bit openexr.

In AE I interpret the rendered footage as "compositing_linear: ACES - ACEScg".

I set project settings to:

OCIO color managed

ACES 1.2

32 bit

Working color space: "compositing_linear: ACES - ACEScg".

Display Color Space: "ACES/sRGB".

If I now export an mp4 with colorspace set to "Color_picking: sRGB", it renders correctly. But of course not in HDR but 8bit sRGB. But at least it seems like I'm doing something right.

My question is: What do I need to do to export this correctly to Youtube as HDR?

I have tried to set the display color space to "ACES/Rec.2020 HLG 1000nits" and then render using AME as "Apple Prores 4444 HLG". But the colors became alot darker.

I also tried to add an OCIO color transform to an adjustment layer before render, but if that is the solution I wasn't able to find the right settings.

Any help is greatly appriciated.

Thanks,

Jakob
