if the way you are encoding is very shitty
yeah it will lose a lot of quality, usually encoding stuff to webm is ALWAYS manual as every video is different and needs different settings
however you still can do a simple prompt on ffmpeg to encode stuff as "it works"
you do not need 8k420fps

this is my own personal prompt i use to encode mp4 to webm

ffmpeg -i input.mp4 -c:v libvpx-vp9 -pix_fmt rgba -crf 16 -b:v 0 -b:a 128K converted_video.webm -y

and this one for mp4 to gif
(this one is to make a palette first)

ffmpeg -i input.mp4 -filter_complex "[0:v] palettegen" palette.png -y

(this one is to use palette and mp4 to make gif

ffmpeg -i input.mp4 -i palette.png -filter_complex "[0:v][1:v] paletteuse" -f gif converted.gif

i have all of these in .bat because no need to fucking copy and paste the same thing all over again

Yes problem solved! thanks !
