very typical for people that never even run or host their own server from data center or even cloud service.
live streaming is worse in bandwidth consumption compare to youtube with same resolution input to output. Like youtube can do whatever they like to keep the outgoing low even if you encode according to spec. But streaming with the demand of like 4~6s delay their 2nd pass to try lower the output bitrate is just not gonna be as good as youtube. That’s why twitch still don’t have 4k stream, they have new beta programs thanks to newer codec on newer GPU, as otherwise their data center is gonna get crushed hard.
