Creation/Translation of LUT for Resolve

[Luis Otero]

Hello,

I am having so many problems to understand/follow a proper workflow to generate decent LUTs for Resolve. My workflow is as follows:

1. Using SA Color Finesse, use one of the Kodak presets included, and apply it to an image

2. Generate LUTs from Color Finesse (all of them, including the one for HDLinkPro3D)

3. Trying to use them within Resolve do not yield anything resembling to the original image.

4. If I load them into the HDLink, it works perfectly, but it is not part of the grading scheme, only monitoring.

5. If I save the same loaded LUT from HDLink that was created by Color Finesse, and apply it to Resolve, it also does not yield anything resembling to the original image (kind of posterizing and banding).

5. If I try to use the "Workflow A" described on the Resolve Manual, the resulting grading is weird and ugly (again, kind of posterizing and banding).


Where can I fing LUTs to download (free or paying for them)? Is there any other workflow you suggest so I can use the Kodak looks from Color Finesse? Are the Arricube LUTs for the Alexa (which do work on Resolve) somehow "cross-referenced" to a specific film stock?


NOTE: The LUTs that work with Resolve (Alexa ".cube", and CineSpace ".dat") have around 35,937 lines. The other non-working generated LUT as described above, or the available for D-21, are within the 4,000 lines.

Please advise ASAP. Thanks!!!

Hi Luis,

I suspect the "SA Color Finesse" is not outputting the LUT in a Resolve friendly format. My recommendation would be use the .cube format, and you can refer to the Alexa LUTs which work for you as a guideline.

If it doesn't support that format, another way is to use the any software to burn/apply the LUT onto the trim_lut0.dpx file and save it as a new DPX file.

You can get this file from /Library/Application Support/Blackmagic Design/DaVinci Resolve/trim_lut0.dpx

Now, take this LUT into Resolve, and use the "Generate LUT from Current Grade" function in the Config/LUTS section to generate a new LUT. There are a few settings you need to set to be able to use this, HD system resolution, etc. (documented in the manual I think), but once you have done this you will have Resolve usable LUT.

Regards,
Rohit

Rohit,

I have done that exactly, but the LUT applied render posterized images.
