LMT_PFE_OFX.dctl LMT_PFE_OFX_neutral.dctl The DCTLs should be used in ACEScct in Resolve, and work with CUDA, Metal (macOS), and OpenCL (Win10).

Use the Edge Detect plugin to generate a mask, and apply it to a node where you blur just the red channel. Blurring edges reduces contrast, causing the brighter outside edge to darken and the darker inside edge to lighten. Applying a max operation to the original image and the adjusted version will preserve the original pixels that were darkened by the process, while keeping the newly brightened pixels. This has the effect of something similar to a light-wrap, though in this case it's just the red channel that leaks. The max operation can be performed in an number of different ways in Resolve, and one such way is to use a layer node with the blending mode set to lighten.

I'm not sure of the exact reason, but some of the precompiled plugins on the GitHub page aren't showing up anymore in Resolve 15. I recompiled them and now they seem to work. Something to do the latest version of Resolve doing some lib file modifications when installing perhaps. Anyway, try using these. https://github.com/baldavenger/Extras/blob/master/mac_OFX.zip

This plugin has the option of a technical LogC Alexa Wide Gamut to Rec.709 transform, but with the additional ability to roll off the highlights into display space.

Peter Doyle used simple math expressions to achieve channel suppression, much like a despill operation (which Jussi was referring to). You can do this in Resolve with LUTs (good) or DCTLs (better). One of my first plugins was called BlueBox, which was based on the process Peter Doyle described in an fxphd interview he did several years ago. An extended version of the plugin, called ChannelBox, is described here: ChannelBox info Links to the source files and complied plugin can be found there too.

I tried with various convolution filters and frequency separation, but found that a quick and easy method actually worked the best (in Resolve anyway). Apply the EdgeDetect plugin to node 02 (a corrector node added to the node graph and connected to the source input), adjust parameters to get your edge alpha, then pipe node 02 RGB output to your main stream (node 01) alpha input, and apply blur. This approach can be adapted to work with channels individually.

Added new plugins Convolution and Frequency, and updated Qualifier. https://github.com/baldavenger See here for more information: http://liftgammagain.com/forum/index.php?threads/dctls-and-resolve-ofx.7046/page-15

SoftClip OFX plugin has been rewritten and updated. Short demonstration video can be viewed here:

BaldavengerOFX plugin collection has been updated. 18 plugins for DR14 (macOS, Windows, Linux), and legacy versions for DR12.5 https://github.com/baldavenger/macOS-OFX https://github.com/baldavenger/Win-OFX https://github.com/baldavenger/Linux-OFX

It's the direct application of the official transfer functions and 3x3 matrix colour space transforms, as opposed to those transforms being first applied to a LUT and then applied via interpolation. It's a clean, non-destructive, and fully reversible process. It's not a question of trust, it's the only truly indisputable scientific certainty i.e. math.

For technical transforms try to use the Color Space Transform OFX plugin or DCTLs. That way you can avoid any potential image degradation that may come from the LUTs.

It's an attempt at emulating Baselight's FilmGrade.
