This command converts a PNG sequence into a JPG sequence:
ffmpeg -i in/%8d.png out/%8d.jpg
However, when using the same command with WEBP:
ffmpeg -i in/%8d.png out/%8d.webp
It will put all frames into a single WEBP, which is animated.
I have not found a way to tell ffmpeg to instead create one WEBP per input PNG.
Is this somehow possible? I'd like to avoid using any shell scripting/loops.
