![]() ![]() In fact it creates an exact match when using a reference wipe, whereas the input LUT yields minor variations, presumably based on the less precise math or LUTCalc having slightly different input values. Using the Sony SLog-3 IDT and converting it to a DCTL file, which then is placed into the LUT folder and used instead of IDT or Input LUT also creates an equivalent image. The code in a DCTL script matches the math precision the built-in IDT use. A DCTL script has the advantage that it's precise math rather than interpolated lookup table. This now opens the opportunity to make additional customizations to this input LUT to taste, or create a LUT that matches the camera specifics of unqiue cameras.īased on this article, the other option is to create a DCTL script. I set the clip's IDT to None and added the new LUT as the input LUT for the clip.Īs seen below, the resulting image matches the reference images from the original IDT, suggesting that the two operations are equivalent. I then created a custom LUT with these settings in LUTCalc. To test this theory I took a clip and set the default Slog3/S-Gamut3.Cine IDT and took a screen grab for reference. This can easily be achieved in LUTCalc (). Thus a LUT that can translate the camera data into linear / AP0 is a proper replacement for an IDT. An input LUT can be applied before Resolve translates the clip to ACES cct color space. When there is no IDT specified in the project and the clip, then Resolve expects the data to be in linear gamma and AP0 gamut. I was just involved in a discussion on creating IDTs for color grading in ACES cct in Resolve 14 when there is no built-in IDT.

Pricing If you want to say ‘thanks!’, you can do so by buying Mr. For further tweaking you can use the very handy online tool called LUTCalc. Note that DCTL scripts require the studio version of Resolve.īen’s LUTCalc – 1D & 3D Cube LUT Calculator v2.1 has all sorts of goodies, such as Grading LUTs and Camera LUTs, Recorded Gamma, Output Gamma, CineEI ISO, Stop Correction, ASC-CDL, Knee Levels, Black Level / Highlight level, and you can even import your LUTs to look at and work on with the LUTCalc. It started out as a simple spreadsheet for generating S-Log2 exposure shift LUTs for Sony's F5 and F55 cameras. LUTCalc is a desktop app for generating, analysing, and previewing 1D and 3D lookup tables (LUTs) for video cameras that shoot log gammas. ![]() ![]() LUTCalc is a desktop app for generating, analysing and previewing 1D and 3D Lookup Tables (LUTs) for video cameras that shoot log gammas.Format: Size: Posted: Article Number: English: Word 2007. ![]()
