    I must be doing something wrong!! My adjustment layers on my ‘screen grab’ look great in Photoshop. BUT when I export my .cube file and apply that same LUT onto the footage it looks terrible. All black and blocky. BTW I am applying the LUT through the ‘Creative’ window in Lumetri.
    The stupid part is…. I have been through this exact issue before, about a year ago. I seem to remember I was doing one thing wrong in my export process. I am just so frustrated because I can’t remember WHAT I changed to fix the issue. I’ve Googled and searched high and low, watched turtorials etc.
    I’m now a bit desperate for some help. Does anyone happen to know what I’m doing wrong? (I SWEAR I’ll write it down this time… )

    did you select a high value in the GRID in the LUT export ?

    Hey Jerry… yes, I just left it on default, which I believe is ‘high’. Thanks for the suggestion though. I’ll go and try a higher setting.

    I tried ‘maximum’ grid points (256). It tool a while to save, and ages in Premiere to ‘apply’ then did NOTHING to the footage in Premiere. Soooo, I tried one at 200. It also does nothing. Has no effect on the footage at all. Hmmm. How many grid points SHOULD I use?

    i can almost certainly admit that they won’t match at first, because they use color management differently.
    premier with color management on, uses your monitor profile, converts it to rec. 709 2.4 then applies a BT.1886 transform. this is regardless of what your source footage is. you’d need to either setup photoshop for previewing in a BT.1886 format or use a preview lut in premiere, like a BT1886 to sRGB/web color.

    Thanks so much for your reply Chris… and on Christmas morning no less!!!
    Ummm… your answer sounds VERY knowledgeable, but you sort of lost me at “premier with color management on, uses your monitor profile” Sorry.
    Can you suggest another way to make LUTS please, with a more accurate indication of how it will look on the footage? The way I’m currently doing it in PS is pretty hit and miss. This is really tricky footage to grade. Band lights…. ugggh. I’m just trying to give it more contrast, and shift the lighting color from blue to much more aqua (cyan).

    when I create luts, I use iwltap, then set it to 64 cube iradas lut with trillions of color from a png HALD image. I don’t use photoshop to make luts directly. It kinda looks like there is a color shift going on there as well. how does it work when you set photoshop to use your monitor’s profile for proofing?

    The problem is, the web is srgb 2.2 and premiere with color management on is BT1886(with it off its rec. 709 but ignores your monitor’s profile). you could use a temporary viewing lut to offset grade in a faux srgb 2.2. firefox would match the best unless you’d want to fiddle with chrome’s color profile tags. i’d use VLC over quicktime. quicktime is kinda all over the place with color depending on old atom tags from 2005 and custom luma levels.

    here’s two luts depending on if your going from premiere or premiere to web/VLC/firefox. one darkens, other lightens. its a viewing lut only, so you’d disable prior to exporting.

    if anyone says it don’t work, i’ll stop posting, but I haven’t heard anything negative yet.
    bt1886 to srgb/rec709 2.2 and srgb to bt1886
