[FFmpeg-user] acv file for curves filter

Hi all, I've just tested the "curves" filter. It works fine with a *.acv file which was created by Photoshop. ffmpeg -i input.jpg -vf curves=psfile="curves.acv" output.jpg But it fails when I try to make the *.acv file with GIMP. Is it possible to export the *.acv file from GIMP ? Thanks,
