Question / Help Pixelated Stream

I've just started streaming and I have noticed that not matter what I do, 720, 1080 30-60 FPS the stream is pixelated when moving. My bitrate is anywhere from 4-7k and it's still pixelated.

Motherboard: Asus Sabertooth Z77
RAM: 32 GB of Corsair Vengeance
Processor: Intel I7 3770k 3.5 GHz
GPU: GTX 680 Super Clocked GPU.

Download: 30 Upload: 7-10

Is there something I am doing wrong?

You are actually using more bitrate than what twitch wants, which is 3500. If you want less pixelation/blurriness downscale your resolution a bit more, and even use 30fps if you aren't happy. Don't expect a perfect stream. I personally stream at 720p30 at around 2000 bitrate give or take so people can actually watch it.

Try around 1700 to 1900. You shouldn't have over a 2k bitrate until you are partnered by Twitch or get quality options.

Just to be clear, though, there's no Twitch prohibition against streaming above 2000kbps. You can stream above that if you want.

It sounds to me like you have an unrealistic expectation from what kind of quality you can get from streaming. At 4000kbps (which, as has been mentioned, is higher than Twitch wants) a 864p60 stream should look pretty good. I'd recommend lowering to 3500kbps and run either 1080p30 or 720p60.

Streaming is inherently lossy and you will not be able to get a perfect image, especially if you're playing a high-motion game, so make sure you adjust your expectations accordingly.

Yeah, after watching your VOD, you definitely have too high of an expectation of what quality can be achieved with streaming. Your stream looks absolutely fine.

My expectations are high, mainly because I want my stream to please. Many, many people are picky and expect the most ridiculous quality. Thanks anyway.

It's just the 2k rule which was applied by LethalFrag. A lot of viewers don't have that great of a computer and/or internet. Usually you would rely on quality options to save those kind of people. If you don't have those, that is going to really effect those kind of people's experience. Reference here ->

Try using a slower preset such as fast or faster, they produce far less blocky pixels, but also increase CPU load. The quality also largely depends on the game you're trying to stream, some will look beautiful even when going as low as 1400kbps @ 720p/30 while others (even after bumping up the bandwidth to 3000kbps) look awful with loads of blocks.

I'm sorry for going offtopic a bit here, but I'd like to clear this up.

Note that while LethalFrag is an awesome streamer, he is by no means an authority on streaming settings. His advice is not bad, and specifically well tailored to his own personal needs. But situations differ from person to person. The support guys from this forum help different people in different situations on a daily basis, and have a very good understanding of what is appropriate under which circumstances. This is something LethalFrag does not have, because that is not his job. His job is to stream, and that video, he made just to show the setup he chose for streaming, because people just like to know that.

I could write a long rant here about how popular streamers sometimes use their authority to promote the worst ideas about stream settings (this is not such a case though, he does know what he's talking about, mostly). But I think it's better if I end here.
