Streams (including Mikogo, TeamViewer, etc.) - technical aspects.

Regarding fullscreen mode, how does he stream then? Everything works perfectly, including in OBS.

He streams in a window.
Take a closer look. 7z is right about the bitrate, but I still manage to stay within my bitrate, but whether Twitch can handle it is another question, and I don't know the answer. In any case, I'm looking at my latest streams and Tvarina's streams – my picture looks better.

The only problem is that the stream quality is too high for widespread consumption; unfortunately, freezes are inevitable, and it's not the streamer's fault, but rather the internet speed and the Flash player's performance, as well as the viewers' connection. Of course, the streamer can set lower values that are acceptable for normal viewing, but the quality will noticeably suffer. I can confidently say that replays will look better than the live stream because you have to wait for the replay to load, while here, it's loading in real-time, so it's not always possible to watch it properly.

Regarding the formula: it was derived empirically and is not for Heroes. There are hundreds of streamers who broadcast excellent quality high-graphic games, but nevertheless, freezes with a slow internet connection are inevitable because the amount of information per second (which the bitrate is responsible for) will be too large. It's the same as downloading HD video. But here, it's not HD, and the server isn't that fast.
