Heres what it looks like.


speedtest says my upload is 5.67

speedtest says my upload is 4.05 when connecting to LA, I'm streaming to an LA twitchtv server.

testmy.net says my upload is 4.1 when connecting to a Texas server.

I've tried bitrates ranging from 2000 to 6000 adding 100 bits each test, and then I redid them all in quality 7.

I've tried the same buffer size as my bitrate, 200 and 500 less than my bitrate, 200/500 more than my bitrate, 2x more than my bitrate.

I change my CPU preset depending on what game It is and I make sure My CPU is below 90%.


So why does my stream look bad? It's all pixelated and blurry no matter what I do.

Well, at the bitrate of 4k you get alot of lag or frame drops.
Keep it between 2/2.5k as you also need room to play online.

Then, are you playing pc or do you use a capture card?

To be honest your stream looks far from pixelated and blurry. the Vod you provided looks perfectly fine for the settings you are using . That IS the best quality for your upload speed, of course if you could stream at 20k bitrate it would look almost like ingame footage but that is not possible on ANY streaming site . The only thing that could improve it a little bit is to set your quality balance lower to something around 7-8. Apart from that your stream looks like a 1080p @30 fps stream should look like .

I tested what playing online really does to your stream, I only need to lower my upload by 200 or 300 to get rid of frame drops and lag when playing online.
I'm using my PC, no capture card.

Are you sure? that video doesn't really show how pixelated it is,

same settings

Does that look normal to you? because I have doubts.


changing quality to 7 helps a bit in some places.

Yea that is about the best quality you can achieve with the bitrate you selected. To me it looks fine , sure if you would record locally with a 100k Bitrate the video would look the closest to actual playing the game yourself. Unfortunately we are limited to low Bitrates due to Overloaded Servers , our viewers download and of course our own upload.

It also depends which game you are streaming , an fps game with simple graphics and small areas like Call of Duty Black Ops would definitely look much better with your settings than lets say Arma3 .

I am able to stream at a 9k Bitrate to Hashd, and the picture looks awesome. No problems whatsoever but over 50% of the viewers don't have a good enough download speed to watch it anyways.

I can understand that you want it to look as good as possible, since i am a perfectionist myself. Sadly a better quality is just not possible yet. I am pretty sure that in the future there will be better/updated codecs/servers to give us a better experience with lower bitrates . Keep in mind that the whole livestreaming thing is still in the early stages of development.

1 fix which is quite expensive though is to get a beastly second pc (3770k / 3930x or similar) and use a lower preset so your quality improves a lot with the same bitrate settings(a friend of mine is streaming with a 3970x at the slow preset and his stream with 3k bitrate looks like mine with 9k). It isn't needed though unless streaming/youtube is your job, you have too much money or you can't die happy otherwise.

No problem , i am always glad if i can help . Plus i had the same concern when i started streaming. Just stream and ask your viewers how they like the stream quality and i am sure that 90%, if not everyone says that it looks perfectly fine!
