if it's a vfx job it's better if anyone use the same colour science to avoid problems, artefacts or anything down the pipe.

For example, a compositor composite an alexa footage with some photoshop elements, stock elements or 3d elements under a rec709 display lut. In nuke it looks good, so no problem.

Then he export a flat comp for you to grade it.

You start working in ACES using an alexa IDT, the alexa footage works fine but the comped element goes crazy as it's transformed with the alexa idt as well.

So you end up going crazy doing lots of keys or masks to get the thing back where it belongs.

if you both work in ACES, the compositor sees the same thing as you see (the beauty of aces) he can take care of the problems in comp and he knows exactely how you are going to see it's comp as well.

Or you both work in YRGB and the comp knows roughly how you are going to see the result at the end, but it's a safe route that everyone knows.

Hope makes sense.

 

 

Thanks for this in-depth answer Orash, I really appreciate it and it gave me a wider understanding of using ACES. 

Last question though, in our workflow, grading comes first then the vfx artists will match their comps with the grade, then if there are fixes to be made in the grading it will be post graded in the online with the output of the vfx artists, meaning I will not go back to the original grade, if it's only minor fix ups. In using ACES in the grading, the only advantage of using it is the color space right? If my output will be non ACES? Is our workflow ideal or should we revise it? Most of our projects are commercials. Thanks!

Are there any advantages in using ACES in non ACES workflows? Thanks for taking the time to reply to my questions! Much appreciated. 

what do you mean by burn in? sorry I'm very new to this aces workflow.

I just want to utilize the color space of ACES inside resolve then output it as non-ACES format like TIFF. Is that possible?

Is it possible to use the ACEScc color space ver. 1.0 then output it as a TIFF file Rec 709? This means that the output will revert back to the default color space of DaVinci Resolve right? 

What I want to achieve is that, my output will be directly used by the VFX compositors disregarding the aces workflow. Thanks!

Where is the Resolve version of this?

This is pretty good! Thanks for this! Never thought about using mattes as stylizing tools in grading.
