GJ R1CH, could you post a screenshot of your exact settings that you use to stream at 720p30? Do you normally use the Xpslit broadcaster or just the codec and something else? I have a solid CPU (i5 2500k that I can OC to 4.8 stable) and a solid connection (6Mbps UL according to speedtest although I think its closer to 4Mbps) so I want to see how far I can push my stream. Thanks.

Quality 10, x264 preset "medium", 1280x70, 30fps, 3000kbps bitrate (you should probably lower this, was testing with VODs). No layered window, no Skype, Aero disabled. CPU usage was around 80% over 4 cores, not sure how well this will work with SC2 eating 20-40%.

hmm, I have an i5 4 core processor; so this should of had some sort of effect, but it didn't.
Now that I think of it, the only thing that seemed to effect the quality on my stream when I tweak the settings is changing the output resolution :/

Cheers Rich, you are a boss. Just came off doing a test, noticeable quality improvement, no framerate drop on Quality 6 - Slow encoder setting. Sadly I can't go to 7 on this connection or higher or it'll drop frames like a boss :[ but it does look much better, thanks!

Wow awesome find R1CH! My AMD quad core I bought 2 years ago is finally paying off. :D

Holy crap. The Wizard strikes again.
The difference between those 2 videos is astounding.

Like R1CH said the bitrate can be significantly lower if you try and run a 3k bitrate stream it will be mostly unwatchable for a lot of people.

Can't believe they were using an old encoder like that. I only have a core 2 duo so I would never have noticed. Thanks for letting everyone know!

How much of a difference does the preset make in Xsplit?

I'm assuming this will affect performance of hyperthreaded dual core processors as well as true quad core processors?

Regardless, this is pretty awesome. We better see epic quality streams from now on

What the heck, now I want to play Q2, lol. That is really cool though, nice work.

I'm not sure what the default "XSplit" preset is, but you should definitely use one of the medium / slow / fast / ultrafast / etc presets as these are standardized settings made by people who know exactly how the codec works and provide the best quality / speed tradeoffs. For clarity, the "presets" apply to internal configuration of the x264 codec, they don't affect any XSplit options.

Thanks R1CH I went from 720p to 1080p (mainly for Epeen reasons)

Not sure if it looks any better, but definitely taking advantage of my 6 cores better (1090T).

Freaking amazing.

R1CH, you're amazing. Also sharing the same name is pretty cool. So from one Rich to another, awesome work and I'm definitely hoping you look into more live streaming programs in the future!
