    The latest page to the PDF is attached. The problem, I believe, is that GH5 VLog L footage has an unusual full luminance flagging for video footage. This was corrected to read correctly in Adobe programs in May of this year. The key for VLog L and LogC footage is that full white (pointed into overblown light source) places below 768. If its above 768, the levels are set to video (which need to be set to 'Full' or 'Data' in Resolve)

    That's a good idea. The Pdf can be a lot to take in for the uninitiated 🙂 With anamorphic, I've wanted to experiment with that for a long time, but have stayed spherical for the time being. I think there are some good complete m4/3 anamorphics now that aren't too expensive (relative to most).

    @Sage I'm still absolutely loving this LUT, and it just keeps getting better and better! 

    I use it for pretty much every single project I shoot, S1 for A-cam and GH5 for b-cam, but lately, combined with anamorphic and pro res raw, it has felt extra tasty. I just love what it does to greens, especially. These screenshots are some standouts from the past couple weeks. Thanks for all your hard work! I recommend your Alexa LUT to all my lumix-shooting friends 👌🏻

    @Attila Bakos Very cool, I was on a 3770k; I switched to Ryzen last year for this very purpose. Now I'd like to swap out to one of the newest Ryzens, but they are sold out everywhere. I'm doing something atm wherein I throw enormous amounts of data in, and the renders can easily go upwards of an hour at 100% cpu. My data files are usually around 1Mb per each; these are going upwards of 50Mb atm
    @zerocool22 CST is a versatile tool that allows whitepaper transforms between any two spaces. These are the manufacturer specified color spaces. Emotive is a measured conversion between two cameras (or profiles etc), such that it factors in sensor response to a light source and internal camera processing (of WB, profile, etc). Emotive has simulations of sensor LogC solely using Resolve color tools (sans CST) called Matrix. Both the interpolated conversions (with Tetrahedral interpolation enabled) and the Matrix LogC simulations are non-destructive, while Arri's Rec709 (that can be added to Matrix LogC) is partly destructive (of extreme Led gamut). CST can be either destructive or non-destructive, depending on the transform specified and relevant gamut.

    XT3 is in the plans, indeed. At this moment, its down to documenting the process of adding a camera to the server, and then streamlining the Pdf writing process as best I can (later today). This will make a camera cycle as efficient as possible.
    From the LogC alone, V4 isn't that different from V3 for the average image. When saturation becomes more extreme, V4 is quite a bit better (much, much more accurate to Alexa). And when using V4 on unintended formats (i.e. Rec709 footage), V4 holds up, while V3 doesn't. Here is a comparison with one of the more saturated images I've got (most notable shift), using Soft (most equivalent variation between 3 & 4):

    Ironically, I've still been working away at the EC engine, and fixing copious bugs (its inevitable that when I think a thing is finished, the work has just begun ) That being said, I think today I've fully tested it, and everything is working really, really well.
    This is a GHa Tungsten LogC render from this morning; the wheels on the far left and right are completely theoretical extreme gamut, beyond what the camera can record - the ones in the center are actual log gamut (and V3 for comparison):

    "Pocket 4K footage is precisely transformed to match the color science of the Arri Alexa, without compromise. This is achieved without artifacts, while introducing a smooth, organic rolloff."

    For the better part of the last year, I've been working to map the color of P4K BMDFilm to match my Alexa's LogC, as measured under sunlight and halogen. To do this, I wrote an interpolation program in C++ that can accept an enormous amount of data (~40k samples per camera), and interpolate smooth internal contours, or 'waves' between them. Exposure compensation conversions were made with the same interpolation engine (transforms replicating sensor color response with variant exposure).

    Another significant element of the project was to recreate Arri's Rec709 to maintain the entirety of recorded LogC gamut, in a film-derived envelope (for the display variations). This was particularly difficult, as the correct RGB primary behavior needed to be exactly replicated within contiguous 709, but smoothly diverge to HDR-like handling of far gamut (where Arri's Rec709 ends). This new envelope (EC Gen.4) is particularly impressive, and I may release it for the Arri, as it is significantly preferable to normal Arri Rec709.
