i5 2500K Overclocked to 4.5GHz
16GB DDR3 1600MHz RAM
GIGABYTE HD7950
OK quick update. Got fibre Internet and my upload is now 1.85. What sort of resolution / bitrate could I do with this without getting any input lag in game?

Depends what you mean by input lag, you're probably good for any resolution you want (up to 1920x1080) but i'd stick to lower framerates for both performance reasons and quality at lower bitrates, and if you're lower end like 720, 30fps, you could probably drop 2 presets and be fine while streaming those resolutions, if it helps noticably and you're streaming games that are not heavily loading CPU (sc2 does not really, CPU bound but it doesn't utilize much of a quad core)

So if I do 720p @ 30FPS, what preset do you think I could drop it down to? Or, I should say what are the best settings I could get for a 720p stream? I'm not too sure whether 60 FPS would be too much for my CPU or Internet to handle or whether something in between would be a good compromise and run fine on my end and for the viewer(s) as well.
Also, do I use CBR or change the quality to a set number?

got a question about audio, maybe someone can help me with this one. Is there a possibility of not having your ts3 audio being streamed? it is kinda annoying...well not for me cuz i dont watch the stream on the side but my only viewers i ve are the guys who are in ts3 with me and thats kinda stupid T_T;
oh btw anyone maybe can pinpoint me into a direction what may be the cause of the problem for one of my buddies...he has a 16k dsl thingy and cant watch the stream, its way too laggy for him. the other guy with the same connection can watch it fine. i am streaming with 720p (downscale option) and 3000bit upstream on 40fps, could maybe go a bit higher but i am satisfied for the most part, even thou i would like my stream to be smoother, it always feels when watching the dreamhack stream for example (or grubbys stream recently) that their stream looks like 2x as smooth as mine O.o

does anyone's boxes look weird when they use any kind of streaming software?
like.. when i make boxes they aren't connected right, no matter how my fps is ingame and in the software. how could i fix this problem?

I see there are a LOT of pages of info here but i am trying to find a way to do affects with OBS (fade between scenes, fade images in and out etc)
I see casters do this as well as obviously they do much more for things like MLG i am wondering if/how OBS can do that type of stuff.
Thanks so much for the help!

I can answer your question just make a blank scene and when you click between the scenes on another monitor you automatically get those fade in and out into the next automatically.
I'm just trying to figure out how to do in picture webcam while playing that is my question.
PM me if you can help much love.

Ok that lets me fade from 1 scene with my stuff up into black however when i go from black into the next scene it still cuts into that scene rather abruptly. Is there a way to cross fade scenes or sources in OBS? I know i have seen it i know i have!

Hi guys.
U think i can stream and play sc2 in 1080p?
I got i5 3570k cpu clocked to 4.3ghz
Gainward Titan gpu
16gb ram
Inet 100/10

How would anyone be able to not steam with this setup? o_O

Hi guys,
i was testing a little bit with obs to improve my stream quality, i noticed that if i change the cpu preset from veryfast to fast the quality improves alot, but i get some lags on stream from that, even tho i dont drop any frames or have ingame lag.
Settings:
720p
60 fps
preset fast
max bitrate 3600
Hardware:
i5 3570k @ 4.20
gtx 680
8gb ram
connection:
25k down
4,5k up
Now im just curious what causes the lag, is it the CPU or my Internet connection ?
Did anyone tested to stream with evenly settings (preset fast) with the same cpu, and got no lag problems ?

The picture quality improves so there is more data to download in order to watch the stream.

Yes, but i think its lagging because its not enough upload bandwidth, cpu power or some wrong settings.
Thats why i would like to know if there is someone whos running preset fast with an 3570k without lag issues.

If quality was only measured by file size, we wouldn't need encoders in the first place.
You're close to CPU limits dropping below Veryfast on such a resolution and FPS on a 3570k@4.2ghz and you can't really compare like that because different games/scenes use different amounts of CPU and different systems have more/less background processes etc. If you were encoding frames and then dropping them between your PC and twitch due to insufficient up bandwidth, it would say so

I tried to stream 1080p with this setup
i5 3570k
Gfx titan
16gb ram
Upload :: 9.7 Mbps 1.2 MB/s
Your Speed :: 9.7 Mbps
setup
1080p
30fps
quality 8
preset very fast
max bitrate 2000
buffersize 2500
I get some "resource stalls 1-3 pr min) it says( i have no idea what that means) and some dropped frames.
I wonder what i can tweak to have the best performance ingame and giving the viewers proper 1080

hey hoping somebody can suggest some settings..my quality is okay with what ive selected, hoping you guys maybe suggest that I can run better.
i5-2500k @ 4.5 ghz
GTX 560ti 448 cores 2GB
8gb ram
720p
30fps
veryfast preset
3500 bitrate
quality 10
i use game capture
I would like to do 720p 60fps, or 1080p 30fps.. can I change my preset to rely more on my CPU since I'm overclocked to 4.5 for a better picture? also, should I use something other than game capture? considering my CPU > my GPU.

Go ahead and try medium preset for 720, 30fps (or just use veryfast for 720p60/1080p30) and you could also check "custom x264 encoder settings" and write "crf=20" without quotation marks in the box if you wanna bump up quality a bit. Quality 10 will limit you quite a bit on low motion scenes with a low resolution+fps like 720p 30fps, but you probably shouldn't use either of those changes (preset or custom crf) with 720p60 / 1080p30

Not sure if you were responding to me, but I'll check it out.
I should have added that when I do 1080p30fps, I hit 100% CPU usage, as well as 720p60fps. Sometimes with 720p60fps, I'll randomly drop to around 88% CPU usage, but it will shoot back up to 100%.
