ACES workflow between DaVinci and Fusion

Recommended Posts

(edited)

Hello everyone! Initially I have posted this message on Blackmagic Design Fusion FB group but haven't got any answers (at least not yet) - trying my luck here to see if anyone is able to help...

I have a question reg. ACES workflow between DaVinci and Fusion and I would love to get some advice.

This project has been shot on Sony FS7 and I decided to use ACES workflow for VFX. Upon importing XML to Resolve I change Color science to: ACEScc, ACES 1.0.3. My ACES IDT is Sony SLog3 SGamut3Cine and my ODT is set to No Output Transform (which is a bit counter-intuitive for me, but apparently correct). Process Node LUTs in ACEScc AP1 Timeline Space (not that it matters here). Using that setup I'm assuming I'm getting EXRs (16bit half-float with ZIP1 compression) that are in ACES color space (reading them in as ACES2065-1 later on).

Now, I want to change my pipeline from Nuke to Fusion. In Nuke, I was setting color management as OCIO with aces_1.0.3 config file being referenced. Working space: ACES2065-1, same for 16-bit files. Then sRGB (ACES) LUT. Finally, exporting each comp with exactly the same settings as from Resolve. Whatever happens next is relatively easy - I need to export ACES EXR sequence to match DaVinci settings, that's a bit vague as to what ACES settings need to be set here (to match "no OTD" in DaVinci), but this can be tested and figured out.

I believe this workflow to be correct - please correct me if you think something is off.

How do I replicate this workflow in Fusion? There is no documentation for Fusion 9 and amount of information about working in ACES, both in general and using Fusion, is very limited. As far as I know, I have to:
- Import my ACES EXR image sequence and create OCIOColorSpace node
- Reference OCIO config file (1.0.3)
- Set Source Space as ACES2065-1
- Set Output Space to... what? This is where I am getting confused. What do I set here exactly? I don't want any conversion to happen, I just want to make sure that Fusion "sees" this image sequence as ACES EXRs and that I am working in Linear colour space... I am trying to set this using different Output Spaces but I cannot replicate the look that I am getting in Nuke...
- I understand that I also need to choose OCIOColorSpaceViewLUT and reference config file up there one more time, then set Source Space as ACES2065-1 and Output Space as Output - sRGB (for example).

Any thoughts, comments and advice would be highly appreciated... And also links and pointers to some further reading. Thank you so much!

If you render out of Resolve with "no ODT", you would bring those shots back as "no IDT".

In Fusion you'd use OCIO only for viewing, but not for rendering.
