Maybe it's time to push my 4.8ghz overclock even higher haha Hm, the more I look at that vid...you sure the one you linked was 720p? It just looks too clear
your stream is 1120x700@60 and his is at 1920x1080 at 45 (i think)
since you don't have the same aspect ratio you should go for something like 1440x900@60 on very fast preset (same bitrate) see how it goes

If you have processes running as admin, you will need to run OBS as an admin for it to be able to enumerate them I believe.
Doesn't seem to be running as admin (both OBS and target program, that is). Probably just unable to target certain programs.

Which program? As long as it has a top level window it should show in the list.

Been trying to get it to target Daum's PotPlayer but no luck :/

What is "dashboard link" in broadcast settings?
Also has anyone done any comparisons on performance and image quality between dxtory and OBS window capture?

I think that this test was made with 720p@60fps + 3k bitrates. Or maybe 1080p? I saw that it was pretty fluent, so I assumed it was 60fps, so obviously 720p.
I'm sorry I can't really help you because I made a LOT of tests yesterday and I can't really remember which one was what.
But I will pm you with some kind of config to tell you exactly what I got.

Dashboard link in the settings is the URL for your twitch.tv (or possibly other) broadcaster dashboard. So that if you click on the "Dashboard" button, your channel dashboard opens in a web browser. You don't need it open, but I think that's where pros start ads and such.
Yes, people have, it's previously in the thread. (IIRC.)

Yeah, pretty sure that vid you linked was one of the 1080p ones. Anyway, I'm always interested what other settings people have come up with in their tests for comparison!
I have a general question though, what settings affect clarity the most? Higher bitrate? Slower encoding preset? Are there certain advanced tags I can use to improve clarity even more? I like the smoothness of my stream right now, but everything looks "fuzzy". I realize 100% that downscaling from my native res (1680x1050) to a lower res (in this case 1280x800) will greatly affect things, but I was just wondering what knobs and buttons I could tweak to get the most clarity possible.

Hey, thanks for using my bitrate/preset guide. :D
That guide was written for XSplit, which probably has higher CPU utilization than OBS. I will do some testing with OBS to see if it's possible to squeeze out slightly better streaming. OC'd high-end consumer CPUs (2600K, maybe the Ivy Bridge i5 even w/o overclocking, etc.) might be able to use the "faster" preset.
As with all of these streaming tools I would really love it if the developers let me use custom ffmpeg/x264 settings for experimental purposes. But put a big warning in the UI that says "don't touch these unless you know what you're doing".

I use "Fast" with my 2600k @ 4.8ghz. It gives great results, my CPU usage barely breaks 65% and I get very smooth gameplay and stream.
You can also set custom x264 settings. Go to "Advanced" in OBS, then check the box for custom encoder settings, and start typing away!

Does "slow" put more strain on your CPU or is round the other way?

Yes. Ultrafast is least strain.
edit: Didn't mean to type 'best' initially since it's obviously situational, as below said. Oops.

Bitrate is most important by far, you should be using the Veryfast preset or slower (if you are using ultra or superfast, change it) but after that, going down presets will only net you marginal quality gains (Maybe 30% going from Veryfast to Slow) while increasing the load on your CPU many times over. Unless you are streaming at a particularly low resolution you can probably only get extremely small gains from changing preset because of massive CPU requirements for small improvements in compression
If you are viewing a 1280x800 video in fullscreen, and upscaling it, it will look blurry no matter what you do, you should view the video in its native resolution, either view it via a media player or something, or use streaming site pop-out window and resize it manually to somewhere around the resolution of the video. If you do that, a 1280x720 etc video can be extremely high clarity in most scenes at bitrates used frequently online, but if you are upscaling video by fullscreening it and it is not your screens native resolution or very close to it, it wont look good at all, regardless of quality. As it stands you are upscaling your video by ~70% and you could have a perfect video, at 50mbits or higher bitrates, well encoded etc, but it would look trash with that kind of scaling.

Wondering if I could get some advice on setting up my stream with optimal settings.

That's pretty much what I figured. Anyway, settled on 1280x800 @60fps with 2800 bitrate on "Fast" preset. Looks nice and smooth and picture is pretty clear. Using an i7 2600k OC'd to 4.8ghz, no impact on smooth gameplay.

First gen i7 or sandy bridge?

Wow, I have to say, this is a big jump from the free xSplit to this. Really good alternative streaming program other than xsplit

Alright, I made some test but you guys have to enlighten me on some points.
Atm, my comp is:
- Graphic card : Gigabyte gtx 670 OC
- Processor : I5 3570k 4.3GHz
- Ram : Kingston HyperX 2x4gb 1600MHz
- SSD : Crucial M4 128gb
- HDD : Western Digital Caviar Blue
- Internet : 50mb(down)/5mb(up)
My config on OBS is:
Quality : 10
Bitrate : 3000
Resolution : 1920x1080 (Standard, non-reduced)
FPS : 60 (That's what I set)
Now that you have those informations, here is a test that I made this morning with those settings : http://fr.twitch.tv/dodh277/b/336210695
It looks like it's 1080p, but it's really smooth, approaching 60fps. But obviously, I know that my comp/internet can't handle 1080p/60fps stream so, is it default 45 fps?
I find it pretty weird that my stream looks that good, even tho it's just a small test :o.
