Thank you so much for this! Hopefully I’m not bothering you with this*.
Did you scale the source with ffmpeg?
I’m not entirely sure, but I don’t think I did. The invoked command was the following:
❯ ffmpeg -iinput.mp4 output.gif
Do you have a visual pattern in your console background?
I don’t think I do. It doesn’t look like it at least. To be clear, even on my laptop I notice the visual pattern visible in the gif. But that’s totally absent when I’m working within Emacs. Or at least, it looks as if it’s just a singular solid color.
The second best to render a small enough size that it does not get resized in the browser.
Hmm…, makes sense. Not a huge fan, though 😅. Hopefully I can solve it through other means instead.
I assume you scaled it up
Yup. For the sake of readability*. But the upscaling (or rather zooming in*) was done natively within Emacs.
Alright, so I went to do some digging and the pattern only starts to show up in the gif. Perhaps as a result of the smaller color palette*. Regardless, I tried to see if it is solved by simply generating a ‘better’ palette and using it as a filter of sorts. Furthermore, in case that wasn’t enough, I also tried playing with different dither algorithms:

Does any one of the above gifs do better?
1, 2, 4, 5, 6 all look fine resized in the post and full size
3 looks fine full size but has slight visual artifacts resized in the post (check/square pattern)
I can barely see it on my monitor. So on worse monitors it may not even be visible. #272a31 vs #262b31
animated webp may also be an option
