    i just found this thread and the logarist software.

    i look forward to using it in fcpx with my panasonic g7 8bit footage which, if i am not mistaken, is akin to the internal gh4 footage.

    thank you balazer for the effort and sharing.

    if you ever find yourself in the nyc metro area, please let me buy you your preferred beverage!

    be well.

    @balazar for the GX85 there's no gamma setting--is it 16-255 or 0-255?

    DrDave, I don't have a GX85, so I don't know which luminance range it uses. Run ffmpeg -i on a clip and tell me if it says yuv420p or yuvj420p. Which photo style are you recording in?

    Jacob, just found out about Logarist, thanks!!!

    I suggest adding an input LUT from HLG on the GH5/GH5s since it should have good DR and it's better in 8bit VS V-LOG I think.

    Or is Cine-D still better as recording profile for 8bit?

    Thanks again!

    The GX85 uses 16-255 (video levels with super whites).

    By the way if a video recording uses yuvj420p your NLE might interpret the source as Rec.601.

    dia3olik, Cinelike D is the best color space to use on the GH5. Use the Logarist GH4 Cinelike D input transform. It's almost the same as the GH5's Cinelike D. Dynamic range is identical in Cinelike D, HLG, and V-Log L on the GH5.

    Hybrid Log Gamma is only available in 10-bit modes, so you can't record 4k/60p in HLG on the GH5.

    True, however you can record it with an Atomos Inferno.

    Thanks!!!!!!

    Quick update...tried it and it has less banding/posterization in gradients than VLOG-L ! ! !

    Do you suggest to keep the Cine-D profile settings at its default to better comply with the expected curve and with black levels
    or can the latitude be improved a little further by lowering contrast to -5 on the Cine-D profile settings?
    (albeit of course having to deal with the raised blacks in post)

    Thanks again tho!!!!

    You cannot change the lattitude by tinkering with settings that move code values around and potentially mess up color fidelity.
    Lattitude and dynamic range are sensor characteristics.

    The only options to tinker with should be noise and sharpness, the rest I would not touch.
    For 10 bit recording I would stick with HLG, for 8 bit I would stick with Natural or Cine-D.

    Hi, dia3olik.

    Yes, Cinelike D has a lot less banding/posterization than V-Log L. Cinelike D is really the better designed curve for the dynamic range of the GH4 and GH5, especially in 8 bits.

    The Logarist Cinelike D input transform is made from a profile of the camera with all of the color and contrast settings at their defaults. If you change any of those, it changes the camera's response and the transformation won't be accurate anymore. In any case that would not improve the dynamic range.
