This WebM here is the same animation as the GIF at rule34.xxx/index.php?page=post&s=view&id=1761451 , but vastly improved.

- The file size is almost 20x reduced, totalling 470kb.
- The frame rate is restored to the original 60 FPS.
- The visual quality compared to the GIF is far, far better. Compared to the source, it's almost indistinguishable. The only artefacts I can see are the sunbeams in the top-left (slightly blurred) and the areolae (very slight blur, only noticeable when paused).

Encoding command:
> ffmpeg -r 60 -i "%6d.jpg" -c:v libvpx-vp9 -crf 35 -b:v 0 out.webm

Adjust the "-crf 35" option to tweak quality. Lower numbers yield higher quality; range 0 to 63
