Correctly using the "3D LUT'" filter in Avidemux?
by TheNutCase from LinuxQuestions.org on (#6G004)
My operating system is Slackware 15.0, and I am in the process of trying to convert the contents of all my videotapes to digital format and in the process, I'm trying to "clean them up" as best as I can using Avidemux (version 2.8.1), but when using the "3D LUT" filter, I try to load the .png or .cube file - and an error window pops up tha says "Invalid file!". What am I doing wrong, and what is the correct way of doing it?
