Anon it's 2025. 4chan accepts 4mb vp9 webms, which you can mape with the wrapper I mentioned. The results are million times more efficient than whatever you did to your webm.

Pic rel, double your webms framerate and resolution. There is compression artifactign when I move around on the noisy ground texture which is normal, but it roughly matches the amount of footage of the sped up clip, while being same filesize, double frame rate, and double resolution.
