Thanks for this, I use it as a raw effect for my video sequencer.

Could you take a look at Direct2D's LUT: https://docs.microsoft.com/en-us/windows/win32/direct2d/3d-lookup-table-effect

Also, this: https://docs.microsoft.com/en-us/windows/win32/api/d2d1_3/nf-d2d1_3-id2d1devicecontext2-createlookuptable3d

I'm new to lut and perhaps you can advise on what to pass to this function. The idea is to use GPU for the color grading instead of the bitmap directly.

This may also help: https://github.com/microsoft/Win2D/blob/master/winrt/lib/effects/EffectTransferTable3D.cpp

Best,
