>>92865906here's my method
1. crop/clip stream (i do both at once in OBS)
2. extract audio from video (there's like 20 methods you could use to do this go find one, ffmpeg works fine) (if you use an mp4 audio source you're a retarded faggot)
3. handbrake transcode to webm, make sure it actually autocrops the black space half the fucking time it doesn't and you have to do it manually, adjust the seconds/frames if you recorded too much
4. remove the audio in the audio tab or you will not be able to post it
5. fuck with the resolution and quality until it's under 4MB but still looks alright
6. use the 4chan sounds extension to combine your audio and video into a soundpost (you can also technically do this manually but i don't know why you would)
7. download it
8. rename the file so the _ is a % because windows is fucking retarded and browsers have to do that to stop environment variable abuse
9. play it to make sure it actually works
10. post your soundpost
