>1. why the fuck would you encode with CRF for 4chan? you need to use a bitrate target so you end up under 4chan's size limit for sure
This targets consistent quality not consistent file size. bitrate target is also less efficient than CRF unless you do 2 pass.

>2. if you don't use 2-pass encoding with VP9 then it deactivates a bunch of quality features
Yeah but it's only like a 10% file size reduction. At least with my limited testing anyway. 40% better compression efficiency vs H264 instead of 50% better compression efficiency doesn't seem like that big of a deal in my opinion.

Best I could do, if you find anything better please share it fren but it has to upload here to others can easily download it ofc.
