PLEASE READ I realised recently that you need to set your output transform when rendering from Resolve to ACEScg, not "no output transform" in order for it to be exactly the same in Nuke. This is ONLY for rendering the shots out as EXRs from Davinci Resolve. The rest of the time I leave it on srgb for proper viewing. Also, a quick note for everyone terrified by the millions of colour spaces from the drop down list! I've spent the day deleting all the pointless colourspaces from the ocio.config file so it's slimmed right down to the main 9 you need for using in Blender. The adapted file is available to download for free on my Patreon (link in description). It's a public post so everyone can access it. Hope that's helpful!

Brilliant ! Very complete. I was just wandering why you have choosen nuke instead of fusion for compositing as fusion also have good feedback and it’s part of resolve which would simplify the workflow ? The ergonomy ? The quality of the tools or because it’ is THE standart in the vfx industry ?
@AlfieVaughan
@AlfieVaughan 3 жыл бұрын
Thanks! Its because I started working for a VFX studio about 4 years ago so I had to learn nuke when I started as it's the most commonly used compositor in the industry. Ive used most compositors for a bit. I've tried fusion briefly, I used after effects for ages, I've used the blender one a bit... And nuke just seems to be the best in my opinion!

This is really interesting. I’m a Nuke user who’s avoided ACES up until now. Really need to make the switch. Towards the end though, when you compare the Nuke comp to the original plate, you mention that the colours are exactly the same, but they’re not. The red jackets hanging behind you, and also the blue box just on the right edge of the frame, all look off. Is this down to something you adjusted in Nuke? Or are those colours somehow off?
@AlfieVaughan
@AlfieVaughan 2 жыл бұрын
It was a mistake I made in the video. You have to set the read node in nuke to aces2065 so the colours match on the round trip. I missed that step in this. If you do that they're identical :)

Great video! 1 question, Im about to color a small commercial in resolve that has vfx in it and the vfx artist has already done his vfx. Now Ive never graded any shots that has vfx nor does the vfx artist knows how to pass it to me but i do believe his not working in aces color space.. Can the vfx artist change its color space to ACES after he has done the whole vfx?
@AlfieVaughan
@AlfieVaughan Жыл бұрын
Yes it can be changed but it would be quite a bit work. The look would change a bit so it would need tweaking. I'd probably recommend just sharing ProRes files in rec709 to keep it standard if you can't switch to ACES

Hi, one step I do not understood. Why not to use output transform for exporting video to exr? In what a colorspace it would then be exported?
@AlfieVaughan
@AlfieVaughan 2 жыл бұрын
I think if you don't turn it off it does t export as linear so it does a double transform instead which doesn't look right once you view it in nuke or blender. This is the way to do it so the colours are identical for the whole round trip through all the softwares

I have a question. This may have been explained in the video but I missed sorry. My question is as follows. I’ve set up Blender so that it renders in Linear ACES AP1 (I don’t know if that is ACES CG, CC or CCT). In Nuke I have it so that it reads a Scene linear file it looks way to dark, and the view transform is default, the project settings are set up so that the working space is Scene linear. When I export it it instead looks to bright, though I don’t know if I exported it as an Matte painting or Scene linear. What am I doing wrong? Thank you for this video. It was very informative but my issue is kind of specific.
@AlfieVaughan
@AlfieVaughan Жыл бұрын
It should be set to ACES CG for rendering. AP1 is its own thing. So ideally you want to work in aces CG for all the post work so it looks the same across blender, nuke and your editor etc. Double check your colour space in the write node too. Definitely don't export in matte painting. Keep the whole lot as Aces CG otherwise there will be colour shifts

@AlfieVaughan
@AlfieVaughan 3 жыл бұрын
You don't actually output an "aces" colour space. The final render from your editing program comes out as sRGB or rec709 mostly. You just work in aces across all the other bits of software and then export Tova delivery colourspace at the end

@@AlfieVaughan I'm working off of Red Monstro footage where I need to camera track a shot. I go to Color Management and change to ACEScc and it converts the RedLog to what appears to be Rec709 however it crushes everything. What would you recommend for prepping the footage to nuke in which I can deliver the client the final as RedLog for them to color grade? OR is this something I have to work off of ACES/Rec709 and deliver as Rec709? Appreciate it.
@AlfieVaughan
@AlfieVaughan Жыл бұрын
It depends how you want to work really. ACES and also the davinci colour managed workflow will both read the metadata of raw footage and automatically convert them to your output transform in the settings. If you want to deliver the log back you can select the clips and choose "bypass colour management" before exporting so it doesn't do any transforms. However I wouldn't recommend doing that as it's not good for VFX to work in log. What all the VFX studios I've worked at do is convert everything to ACES CG and then provide those EXRs to the colourist and they grade using them instead of the log. It's possible to do a transform from ACES CG back to log before sending it if they really want it but I dont think it gives a perfect result going back
