I get a green light from the speedtest to the server, so I do not understand why the video stops from time to time while the sound keeps going. I also have no fps drops on my computer or anything of that sort. i5 2500k, 8gb ram etc etc... Any ideas? Tried all the way from 1300kbps to 2000kbps and none of them should cause this lag, right? And this is my test on speedtest.net ![[image loading]](http://www.speedtest.net/result/1757832659.png)
Pfffff.... who needs Sweden. I'll stay right here.

So informative.
Thanks so much!

GunRun, A while ago (even now perhaps) I was given the advice that you should have your buffer = 1/4 of your max birate (2000 bitrate, 500 buffer). However here, your amazing guide says it should be 1:1 ratio (2000 bitrate, 2000 buffer).
Why is that?
Like, any hard numbers/proof/theory on why 1:1 bitrate/buffer is better then 4:1 ratio?

Awesome thanks! Quite helpful.
|
Very useful post... now i only wish i'd have a powerful enough pc to stream 
|
Does anyone know how to have your microphone also be broadcasted with the stream?

No no no, read the Xsplit official FAQ. It says either 1x or 2x your bitrate, 2x bitrate is recommended.

Max Bitrate - Keep this 500-600kbps below your max upload rate. (Going above 3000kbps may cause issues for viewers who do not have a sufficient Internet connection)
you know its bad when your upload rate is 400kbps and if you goo 500 under you stream at -100 T_T
other then that very imformative post!!!

Is a AMD 3.1 Ghz tripple core good enough to stream?
You will get ingame lag with that CPU.
For those who own AMD processors, such as myself, it is highly recommended that you should go for at LEAST a AMD Phenom X II 955.
I have a Phenom II X6 1100T (OCd and watercooled) and it does the job pretty damn well. Intel i5 or i7s are a lot better, though, and if you have the cash, go for the upgrade.

When I try and stream my play, I get some lag in my actions. Which part of my setup is likely the culprit?
Phenom X4 II 955
4 GIG RAM
2GIG Video Mem AMD 8970
Could it have anything to do with my internet UP/DOWN?

I had a triple core Phenom II and had a really, really hard time streaming. To the point of it almost being impossible to stream HD.
That extra core on a quad core makes a world of difference.

I am not sure if audio os covered. But for some reason it seems whenever I stream. I always get a sort of echo on the audio on the stream, or almost if it sounds like its coming from a outside source other than the computer, even with my mic off.
Any suggestions?

Just used this to get a stream up for getting coached; was really handy. Did have a problem where my mic was the only audio hitting the stream. The stream wasn't getting game sounds or the coach's voice.. Anyways thanks Gunrun!

nice overview, however this is wrong:
"if you have a very powerful CPU (inluding the recommended ones) you can try “faster” or “fast.”"
this refers to x264 encoding presets. Actually fast and faster require less performance then default, normal, slow, slower and so on. As slower you set it up to ultraslow the more performance you require.
|
Simple question:
If I got the Hauppauge Colossus would I still need a blazing CPU to stream, or would Hauppauge Colossus handle most of the heavy lifting? I have priced out the upgrades necessary and a full upgrade is not in the budget(mother board needs to be replaced for a more up to date CPU), so that is not an option. Also, will I need to split my output to my steam and the card as well? If I am going to order one, I want to order all the necessary cables and adaptors as well.

Thanks for taking the time and making this awesome post Gunrun.

Default requires less performance than fast and faster since it's more or less equivalent to veryfast.
And by the way, even if your computer is half as powerful as the cpus mentioned you should try faster and fast.

I don't think xsplit can directly stream another h264 source (someone correct me if wrong), that is, without encoding again, so it would be a waste over buying a cheaper raw capture card.

The prices of any of the cards is not a huge issue. My real question is will the card handle the streaming aspect without further(or minimal) burden on my CPU. I will buy whatever card does the job, but I want one that works with Xsplit without to much trouble.

Are there any guides out there on how to set up the Blackmagic Design Intensity pro for PC streaming? I'm wondering specifically on how the connections to it work. Do you connect an HDMI splitter to your video card and send one to your video card and the other to the Blackmagic PCI card? How do you stream sound if your video card is only set up to do video?
Thanks
