Is there an easy and reliable way to convert LUTs in Cube format to HaldCLUTs on Windows?
I have a bunch of film simulation Cube LUTS I used in other apps and I would like to use them in ART.
It would be cool that ART supported the Cube format in the future but I don’t think is going to happen anytime soon as RawTherapee doesn’t support this format either.
Both Gmic and imagemagick can do that. I don’t remember the exact commands but @snibgo and @David_Tschumperle should be able to help
I have heard that ImageMagick can do this. It certainly has code to read (but not write) .CUBE files. It should work like this:
magick in.cube out.png
… to create out.png, a Hald CLUT.
With G’MIC :
$ gmic input.cube r 64,64,64,3,3 r 512,512,1,3,-1 o output.png
I should have said this can be done in batch, to create a png file from each cube file:
magick mogrify -format png *.cube
I don’t use cube LUTs, and can’t check that this works as expected.
Thanks for all your answers!
