1. Quality is grainy / pixelated for some reason, even on 1080p
2. No stuttering or fps loss
3. No clue of streaming and copyright but don't you run risk of getting banned for broadcasting music?
4. Not everybody wants to listen to your music. If we want to listen to music we can just turn our music on in the background.
Pixelated af, probably because you're running a low bitrate on 1080p. Go for 720p60 instead, and you'll probably still need to increase the bitrate for that to look decent.
too low bitrate or too fast preset
fps is ok
it looks like shit but in 60fps
let me know if its good quality rn
