I really like this filter, though I have a minor issue in that exporting gifs isn't exactly 1:1. I found a way to use dithering in a way that can mimic transparency effects when viewed through one of the filters, using horizontal strips of color. But when I try to export the gif, the end result fails to capture the effect, despite it working fine when viewed through the filter itself. Is there any way around this issue?
It might be the limited capabilities of the gif file format, like it only supports a maximum of 256 colors (8-bit), while the filter makes use of 24 bit colors.
One way to capture it better might be to use something like OBS (Open Broadcaster Software) to capture it like a video. But then you will have compression artefacts, which may or may not invalidate the effect you want to capture.
I don't really know of any way to capture a video which fully do justice to the filter. It really is best viewed live.
