This is a free ACES Input Transform (formerly IDT) I made for new ARRI ALEXA 35 camera and its new color space LogC4 AWG4. Unzip the downloaded archive. Place ARRI LogC4 AWG4.dctl file into:

Windows:
C:\Users\Username\AppData\Roaming\Blackmagic Design\DaVinci Resolve\Support\ACES Transforms\IDT

Mac:
/Library/Application Support/Blackmagic Design/DaVinci Resolve/Developer/DaVinciCTL/ACES Transforms/IDT

This will add the new IDT to ACES Transform OFX as well as to ACES Color Science on a project and a clip level. In other words, you can select it just like any other built-in Input Transform.

If it works wrong, please let me know. Haven’t tested it with the actual footage yet, just put down the specs in C.
