>alpha mode 1 missing from 4chan webm after upload
Hmm so it seems 4chan strips the transparency metadata from webms you upload here. That fucking blows, this bullshit thread could have been exponentially more useful otherwise. On a related note it seems that ffmpeg supports webp natively now so all of this can be done through 1 line, like this:

for %f in (*.png) do ffmpeg -i "%f" -quality 100 "%~nf.webp" & ffmpeg -framerate 1 -stream_loop 1 -i "%~nf.webp" -c:v libvpx-vp9 -quality best -crf 10 -qmin 10 -qmax 10 "%~nf.webm"

I'm not sure what resolution would be ideal but I'll try to stick with 720p since that seems like the minimum resolution VP9 was intended for and fits nicely on a 1080p display. Also crf 5 seems kinda overkill imho, I don't notice a huge improvement over crf 10 so I'll be using the latter.
