DaVinci Resolve DCTL and OFX Plugins

The RRT function is on capital letters but in the library is on lowercase.

This should be changed back to uppercase. I was running tests with the new Combo Box option and there was a conflict, but uppercase maintains compatibility with the ACES 1.1 plugin.

The IDT for Alexa Raw it has two 00 more at the end. I’m also not sure about this IDT since I’m using it with arriraw footage and it goes almost fully white, the other Alexa IDT works fine, I tried find info about this IDT but didnt find so maybe is special?

I forgot to add the 00 to the end of the function name. The function itself is a direct translation from the original CTL header, which was probably not intended for use within Resolve in its current form. It’s in the library purely for the sake of inclusion. The exp_factor is what is returning super high values (it’s 36 in the original CTL).

I have a question about where does the dctl work. I mean, I should cut the pipeline in the middle to work in the node between( As I would do with the standard ACES plugin, or does the dctl work some stuff(IDT) before the node operation and the others at the end? Like it would happen if you use the color management tab.

The ACES DCTL set should be used in Resolve YRGB, but the LMTs can be used in Resolve ACES (provided they included a conversion to and from ACEScct). In Resolve YRGB and Resolve ACES you can apply a DCTL as an input transform (pre node graph), within the node graph (clip level, and timeline), and as an output transform (post node graph). Fully modular. In Resolve ACES at the input level, the DCTL is applied before the conversion from ACES to ACEScct (or ACEScc), so an IDT DCTL can be applied here if not natively supported in Resolve.
