On the encoding tab I have Use CBR checked. This is constant bitrate and makes it run at a steady rate instead of fluctuating on the fly based on the amount of data. I run at 3000 bitrate, but this can fluctuate based on the power of your cpu, the needs of your users and the amount of bandwidth you have available. I found 3000 to be good for a 1080p 30fps stream as the sweet spot between people trying to stream at full res on mobile or desktops. Any higher and you pretty much shutdown mobile users (though youtube might not have this issue since they seem to have ‘stepdown’ in place for bitrate and res)
Audio bitrate on the same tab is 112 48kHz
Video tab I run at 1920x1080 with no downscale. I did downscale to 720 for awhile and some people still wish I did since that seems to allow more mobile viewers (again might not even be an issue with youtube). You seem to play at 1440, not sure if downscaling to 1080 would be better or not. Probably have to test it out. The difference in data between the two might mean it will be worth it to avoid any blur though. The blur from downscaling will be less drastic than the blur from the encoding issues I’m referring to.
The advanced tab is where things get interesting. I assume you’re playing on the PC you’re streaming from so changes here can potentially be pretty drastic to both experiences. Will have to test some things out and find out what you can get away with. For me I found one of the big keys to eliminating the blur during fast motion was changing the x264 CPU preset to veryfast from faster. This drastically changes the CPU usage though and could potentially make your game stutter or chug. For example when playing Vermintide there is no way I can use this setting, the game almost becomes unplayable. However when using my console I can crank this up since the PC isn’t being used as much. Keyframe interval is 2 and Use CFR checked.
The resolution and downscaling, bitrate and CBR setting, and the x264 CPU Preset combine to give you the ideal settings to get best picture during movement. Finding what works for you will take some time and someone to watch the stream with you while you change settings, stream and repeat until you find the sweet spot. Finding a fairly spu demanding game that you can move the camera rapidly in to test will be key.
when playing games without fast motion, like a TBS game or the like you can likely use a different profile altogether and just crank up the res to have a crisper picture.
Hope my drunken ramblings didn’t ramble too much ;) Let me know if you have any more specific questions about anything. Personally I’ve been happy with my settings, I just really need a microphone that’s worth a damn.
