THESE ARE MY SETTING can someone help me with this cuz i am currently not streaming at max quality with this bitrate its all blurry etc and i would love to stream max quality but i still want the people who are watching to see it without experiencing laggs or skips in my stream, cuz i can easily handle a high bitrate

I would try downscaling it. Go to settings, and under Video look for Resolution Downscale. This will let you shrink the size of your stream. I have mine set to 2.0, and the video quality is excellent. It will be smaller, but it should look much better. People probably wont even notice that it's smaller, unless they watch the stream in fullscreen.

well i already tried in downscale but then it looks crappy, what about downscaling to 720p and then bitrate like 3500? btw im trying to stream league of legends full HD just saying

Hey a couple of points:

1) You aren't using CBR. Check CBR and that will keep your bitrate consistent. You don't need to use a custom buffer rate, keep it the same as your CBR.

Could you define 'laggy' by the way? Are you dropping frames whilst encoding, so the stream is skipping? Or are your viewers buffering? If they're buffering then that may be because you aren't using CBR and you're streaming at 1080p - this means you will actually be spiking much higher than 2500 bitrate which could be more than some stream viewers download speeds can handle. Using CBR may fix this.

As a non-partner of Twitch the battle is a balance between quality and the amount of viewers that can view your stream without buffering. If you stream 1080p @ 30 FPS with a CBR bitrate of 2500 your stream will be quite blurry. You should probably downscale to 720p and keep your bitrate between 2000 - 2500 as a trade-off so your viewers don't buffer.

The alternative is having your CBR at around 3000, a resolution of 1080p @ 30 fps and you'll have to tell the viewers that are buffering that they can't view your stream without faster internet!

should i put the filter on Bilinear? and what about using 60 fps @ 720p and 2500 bitrate

 

[Kiada]

Set the filter to Lanczos and I could personally settle with 60 fps and 2500, though it will still be a tad blurry. Don't be afraid to tweak some settings and record a few test videos to file locally! The quality you get on the locally recorded files is the same as what will be broadcast to Twitch so it's a quick and handy way to check out different bitrates and framerate settings :)
