Fujifilm's free color space converter.
Fujifilm makes high-end LUT boxes allowing both color space conversion and look creation. The flagship IS-100, a.k.a. CCBOXX, is a full-freight, ACES-compatible color management system, while the IS-mini is a more compact (and affordable) LUT box with ASC CDL color-correction and look-creation capability.
The IS-mini Color Space Converter is a free subset of the IS-mini's manager program, eliminating the look-creation functionality while still letting you create LUTs mapping a camera (or a raw color space) to a variety of output color spaces and brightness renderings, including several HDR transfer curves and wide color gamuts.
The IS-mini Color Space Converter (click or tap for larger) Fujifilm has collected IDTs (input device transforms) for quite a few cine-oriented cameras, from REDs, Alexas, and F65s all the way down to the Sony A7S, Panasonic GH4, and GoPro HERO 4.
Fujifilm has created four IDTs for the GH4, which is four more than Panasonic has According to Fujifilm's Michael Bulbenko, 95% of the IDTs were created by Fujifilm itself; the "only way to get that many cameras profiled is to do it ourselves, [and] they are super accurate."
You have to be online the first time you pick a camera and its setup, as the IDTs are stored on Fujifilm's server and downloaded on demand, but once downloaded they live on your computer for future use.
IDTs must be downloaded from Fujifilm's server The app shows you luma mapping between your chosen input and output as well as a symbolic representation of the color space conversion. You can then send the 3D LUT to an IS-mini or export it in a variety of formats for use in other programs:
Three sets of LUT export options (click or tap for larger) Generally speaking, "Grading Soft" LUTs tend to be high-precision 66-level LUTs for final finishing; "VFX & EDIT" LUTs usually have 33 levels, and "on Camera and Others" are compact 17-level LUTs for field use in memory-constrained EVFs and field monitors. All are 3D LUTs, with an optional 1D shaper LUT for Resolve.
The software was released in January so it doesn't have all the latest cameras — no DVX200 or Varicam LT; no A7SII or A7RII — but that aside it's a handy resource. I've used it generate LUTs for my GH4 that are far superior to using Panasonic's Varicam 35 LUTs, and I've put 'em in Video Device PIX-E and Convergent Design Odyssey7Q+ monitor/recorders for field use as well as into Color Finale and Resolve for grading.
The Color Space Converter is available for MacOS and Windows, and the free beta version will work through the end of the year: Fujifilm has put it out for field testing and feedback, so if you find something you like, or feel it's missing something you need, let Fujifilm know. The Color Space Converter page has all the info, download links, and an email link so you can tell 'em what you think.
Disclosure: I helped develop the PIX-E recorders and I'm a beta-tester for Convergent Design. Aside from that there is no material relationship between me and any of the vendors mentioned.
