DJI ProRes RAW to ACES CCT

Flame Flame Questions
1

I’m trying to convert DJI ProRes RAW from the DJI Ronin 4d to a format I can work with. EXRs are good, ProRes 444 is good. All can be in ACES CCT or Arri Wide Gamut.
I just can’t get the settings in DaVinci to play nice. Part of the problem is it’s neon like lights that need some gamut clamping, which I can do in Flame. So they don’t look correct.

Is there any other way to do it than DaVinci? If not, what are the magical settings for DaVinci

This post is a bit old now, but this is how I transcoded ProRes RAW in Adobe Media Encoder. That would convert it to EXR or ProRes, but in the origin LOG format, then in Flame they now have DJI LOG in the Colour Management node for conversion to ACES or whatever. Hopefully may help.

I’ve heard Assimilate Scratch is very good with ProRes Raw but I always want to throw things whenever I try to understand its UI. Maybe your brain is better than mine, though…

Thanks for this. Unfortunately it’s got some very high sat values causing blow outs in the blue channel specifically.

Would a gamut compression help? If I remember correctly, Resolve has a node, or some option within of its ACES color transforms , to applies it.

this can be fixed with:
/opt/Autodesk/colour_mgmt/configs/legacy_configs/syncolor_ctfs/camera/ACES-blue-light-artifact-fix.ctf

use openexr/AP0 to transport your pixels into flame.
use this ctf to normalize the blue (and sometimes magenta) problem.

Thanks for this. I was able to grade around it but will definitely remember this fir the future. There is also the matchbox for fixing wide gamut material.

Tried it. I think it was just shot incorrectly. All the time I spent chasing rabbit holes, I’ll never get back.

I was able to kludge the fix for this problem. I think the DP shot in REC709. Bad selection with the extreme colors that were present in the scene.
DaVinci
Project Settings

Color Science: ACES cct
ACES Version: 1.1 - I’m on Flame 2025.2

In the COLOR Tab
Added a Color Space Transform to the first serial node

Input Color Space: Rec 709
Input Gamma: Rec 709

Output Color Space: ARRI Wide Gamut 4

Output Gamma: ARRI Log4

Added a Second Serial Node to get the grade into an area with no clipping and similar to a log look.

Output Tab

Export Video: EXR RGB half. Render at source resolution. Color Space Tag: ACES(AP1)

Flame

I wound up loading them in as REC 709. Could have probably adjusted the export tab for that.

I know that probably one or more of these settings didn’t make a difference. But at least I was able to get a reasonable grade in Flame without crazy out to gamut colors.
As was mentioned earlier, there are matchbox gamut limiters and also the ACES-blue-light-artifact-fix. They might have helped but i was able to get a reasonable fix without them.

I still get lost in Scratch’s UI sometimes, so I refer to their knowledgebase. Its search feature usually gets me the info I want. Plus their product designer, Mazze, is easy to get a hold of via email, Google Groups, Facebook, Instagram, and even Discord. The unofficial Discord server linked is run by veteran user Alex Pearce and frequented by Mazze and, I believe, the rest of Assimilate’s team. Great place.
