    Tinkered with the LUT some more and I'm starting to arrive at a point where it's a really good and neutral place. Gonna start beta testing with it on real stuff as well.

    I've made some more changes to the LUT so this is really the version before it. It still is going from 0% - 100%, but is a bit less contrasty. It especially counters a green cast and how shadows...

    That's why Red has different rolloff versions of the transforms, in order to give that control while enable a standardized workflow. And this is only a problem if people use the settings version of...

    I don't think it's a problem for larger productions, IPP2 is more niche for fast turnarounds and lots of productions use ACES or develop their own LUTs. For DXL2 they have their own color science...

    It's a wavelet compressed RAW file. DCT in Komodo.




    But for something to be used as an output LUT or tone map with a grade set before it, you can still get textured blacks if you want. The...

    Here's another weird thing I've found when checking the LUTs. Seems to be some inconsistencies in the S-curve of Red's High Contrast / Soft roll-off.

    The explanation under the video doesn't make sense. Komodo shoots RAW, there's no "in-camera tone mapping" that is in any way hardcoded. And if shooting in ProRes that is a lossy 422 codec so it...

    How do you mean more accurate? Within a dedicated 709 timeline it does transform correctly, but the color cast, especially greens, goes through the roof. So I'm wondering in what way we're talking...

    No, it's something else going on here. When I choose RWG/LOG3G10, it creates this problem. If I instead choose RWG/BT1886 or any other except RWG/Linear it fixes the weird color glitch. If I then...

    Didn't expect a magic bullet, but that the transform works more in line with how the IPP2s do it, meaning expanding everything and not just a semi-LOG. It's alright though, as long as it's intended...
