Do you have Resolve installed anywhere? I see a “Linear to Rec.709.cube” file in their LUT dir that may or may not be what you need/want. On Windows it’s in C:\ProgramData\Blackmagic Design\DaVinci Resolve\Support\LUT\VFX IO\, on Mac I have no idea.
There are a few problems with that request, cube luts have issues with values above 1 so you usually need to go to log before you apply a lut.
The second is that the 709 you get from linear always needs some interpretation, there is the basic approach of just clipping stuff above 1 (ugly) or a tonemapped approach.
You can however use ociobakelut or resolve to generate stuff that might work, usually cubes wont work though. but do give it a try, make some nodes in resolve using aces transforms and colorspace nodes and export a lut.
the luts that ship with resolve seem to be non standard cube luts so they will
probably not work.
For tracking (I use 3De) I usually use acesCC (log), or even just rec709 stuff is more than fine.
+1 on the color mgmt chat. In my experience, rec709 jpegs are a favorite of tracking bods. I think mostly because you don’t need a lut and the jpegs are very lightweight compared to exrs.
