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.
Really shouldn't bump up resolution just because you can compress better, you're still going to run on limited bandwidth. Streaming wise off a ABR quickly encoded i would probably run 2k-3k kbits then double that for 1080p to maintain quality at erratic screen changes like you would in a game. You don't really need such large resolutions Xx144p scaled up like 1024x576 are good resolutions, the bigger the screen the more bit rate required to maintain quality, lower resolution the fuzzier the picture people should find the balance that they can run a stream that doesn't turn to shit at fast screen changes.

Will this also help out hyperthreaded i7's more than processors with only 4 threads?

Wizardry shenanigans... there is always a price to pay in the end i tell you what!

I noticed an increase in performance while playing SC2, but if I play stream and turn on WoW xsplit just crashes with no error box or anything, it just closes as soon as I go into WoW. I have an AMD 955 BE, windows 7. Any ideas how to fix or why it does this?

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%.
Wondering a couple things rich:
1: You mention no skype... does skype somehow interfere with streams or add lag of some sort? I often run skype while streaming and am sometimes in a skype call with people (especially when co-casting a tournament for example). Would there be improvement using something like teamspeak for this instead? Is there something specific about skype that lags the system or something?
2: I've been using VHMultiCam and FME 2.5 for a while now with some minor issues but for the most part some decent success. I've been hesitant to even try XSplit as I've been told it completely messes up your VHMultiCam config/install and thus I'd have to reconfigure everything if I decided I didn't like it and wanted to go back to VHM. Is XSplit superior enough to VHM to warrant the switch? Does it have the same functionality and customizability (i.e. I like the features to be able to add images on top of the stream, have 12 different presets to switch between, add my webcam on top, and fade between the presets)?
3: When I cast the TL Open from the TL House you guys were using VHMultiCam (tho granted using a capture card so you didn't have the resource hog of VHScrCap) on the streaming computer. Have you since switched to XSplit? Or if you're still using VHMultiCam on that one but using XSplit for personal streaming, what's the reason to keep VHM on the TL Streaming computer?
Thanks in advance!

What do the slower/medium/faster etc mean? What gives better quality? Slower?

Skype itself is a pretty big CPU hog with all the bloated theming and codecs it uses. It wasn't designed as a low impact VoIP program whereas things like Ventrilo / TeamSpeak / Mumble are. XSplit can also integrate with Skype via the settings option, which I was referring to the fact I had turned off.

XSplit will destroy VHScrCap and Multicam on install. Up until now I've been reluctant to use XSplit due to it's poor encoding performance and the fact it requires login and has had unstable login services, thus the lightweight nature of Multicam combined with FMLE was ideal. XSplit is beginning to improve upon Multicam features though like supporting transparent images, more scaling and better video options. XSplit can still act as a DirectShow source to applications like FMLE so you don't lose too much by trying it, and Multicam also suffers from the same scaling bug that blurs everything so you don't get any quality loss. At worst you won't lose any features by switching.

Currently, "because it works". We don't want to mess around too much with the streaming setup with important events such as the TSL3 finals coming up. After TSL3 I'll definitely be playing around and running XSplit for events like TL Attack (although there's an outstanding bug with XSplit desynching with the specific capture card we use somehow).
XSplit's biggest overhead seems to be the scene effects, even with an empty scene it can eat up 15% CPU which is almost an entire core. I don't know what they did vs Multicam in this regard but it doesn't seem right (wouldn't surprise me if the ugly skinned interface was to blame somehow). This kind of mitigates some of the benefits, I'd ideally like to try it with DXTory or some other method that doesn't involve GDI screen capture.

Yes. The preset names refer to how much time the codec spends making a frame. Slower means it spends more time encoding so it can produce a better quality image, but produces overall less FPS, it's not really designed for live streaming. For live streaming you probably don't want to try anything slower than medium or fast.

This is awesome R1ch thanks
|
Just edited almost all my settings thanks to R1CH's input and knowledge (which appears to be endless, naturally!)
Here are my computer/internet specs: AMD Phenom x4 965 (Quad-core, 3.4 GHz) - 2.08 upload rate.
I set the following: - Present: Medium,
- Quality 10
- Bitrate: 1,200
- Buffer: 300
- 25 FPS
- 1280 x 720 resolution
Hope this helps those in a similar standing.

Hello,
R1CH, please. Make a new R1Q2 =D
|
R1CH, this is just freakin' awesome. Thanks a lot for this great find. 
|
Got a pretty significant performance increase for my PC (AMD 555 3.5GHz (OC) with 3 cores unlocked) using this.
|
What would TL do without you?
Thanks for this tip, hopefully I can now stream in 1080p instead of 720p. Looking forward to see the stream quality of the progamers rise too, although I fear that they often don't have the necessary bandwith.

Working amazing so far on my laptop. TY.
|
I love you for this, R1CH, thank you so much! <3
|
R1CH is like a god, except he answers to prayers :D
|
wow great, gonna try this tonight. Any clue if this will give a good performance increase on a i5 2500k stock speed?

Why would you have a 2500k at stock speed? To overclock you need to change literally one value in the BIOS.

damn R1CH.
Thanks alot for this, you are a hero :D
