There are so many ways to do this, and it partly depends upon whether you are grading
on set or just want to see the output of a camera in an ACES-like mode. ACES proxy is
designed for a 10-bit output that can have a LUT applied to have the rendered RRT+ODT for a display
applied. But there are other ways, the IS-mini can be used as a LUT box if you have ACES proxy out.
Sony cameras can output ACES proxy with LUTS (see
I think Canon cameras also have some capability there.
I know that you can also use some LOGs outputs, convert them to ACES and then apply the RRT+ODT and
see it on a monitor. This can sometimes also be used if you have HDR monitors. If you don’t have at least a 33-cubed LUT, you need Tetrahedral interpolation in the LUT to avoid ‘scalloped’ (from arraypt to arraypt curvature).
If you are trying to grade with Resolve in the middle, I would think you would have the IDT on a 3D input LUT
to convert from camera-format to ACEScct. Then the 3D output LUT would be Acescct->aces->RRT+ODT_709 (or other)
But I haven’t tried that myself, and always need to check LUT resolutions and rendering to make sure it is delivering.
