Any WebM wizards here who can help me compress a webm? I need to get it to 6MB to be able to post on 4chan. I CAN do that, BUT it ends up looking like porridge. So how do people compress webms so much but they still end up looking great? If you can just spoonfeed me what I should write into ffmpeg that would be great. Original file is 95 seconds long and 300MB. (mp4) Using Windows.

>>1568193(OP) cut the resolution in half or the length. your choice.
>>1568193(OP) https://www.youtube.com/watch?v=r6Rp-uo6HmI sadly some videos are unsalvageable if they have too much footage with motion, the wizards just chose anime and cartoons with lots of still mono-colored backgrounds and minimal character movement that are friendlier to an extreme compression scenario
https://github.com/argorar/WebMConverter try 720p 30fps with vp9/2pass enabled and 64kbit audio bitrate

>>1568193(OP) Just lower the resolution a lot. If you want/get asked for full resolution just upload the original to some service.

turns out AUDIO eats a lot of space, so I just cut audio quality to 1/5th of what it was and managed to get better video quality this way. It's obvious now in hindsight but it was the thing I had overlooked.
Just change the location of FFMPEG at the top. I put mine in my downloads folder, but you can put it anywhere.

I think you can go 20% smaller if you do av1 encoding rather than HEVC/H.265. You probably don't have hardware support so it'll be slow. I've found success in setting the quality factor higher, but I too am still unsatisfied with my compression levels
