Hi. For several months, I’ve been trying to recreate the effect of an old VHS tape in GIMP. So far I’ve got pretty nice results, but to make them more accurate, I’d need to decompose an image to YIQ channels, and then compose it back in RGB again.
I’ve searched the web, but there aren’t any programs which can do it for me. I’ve seen several pieces of code in Python, C++ and MathLab, and there are matrixes available for conversion from RGB and other formats. But, alas, at the moment there simply aren’t any standalone programs/plugins which can accomplish this task.
I’m not familiar enough with coding to make a program myself, so I’d like to request this feature in GMIC. I’d appreciate it a lot and it would help me to understand VHS better.
