I would recommend that you start lower and slightly turn up the Quality (OBS > Settings > Video > Resolution Downscale start with 2.25) and see what your stream is doing and if u have any dropped frames in OBS. The Bitrates Examples below are just suggestions for some settings. The most Important Value will be your Upload Speed Test with So a 2Mbit Upload means your Uploading 0,25MB/s = ~250kb/s. The difference between a Gigabyte (GB) and a Gigabit (Gb) is the same, with a Gigabyte being 8 times larger than a Gigabit. This is not the case, a Megabit is 1/8 as big as a Megabyte, meaning that to download a 1MB file in 1 second you would need a connection of 8Mbps. People often assume that a download speed of 1 Megabit per second (1 Mbps) will allow them to download a 1 Megabyte file in one second. One thing that often gives people confusion is the difference between a Megabyte (used for file size) and a Megabit (used for download speeds). The Difference between a Megabyte (MB) and a Megabit (Mb) Wireless Connections can be painful when you’re struggling with upload speed already. From my own Experience I highly suggest to have 2 Mbits or better upload speed to stream I would like to add some more things after the basic Setup.
