Luckily, there is now a new program that does all of this, OBS, or 'Open Broadcaster Software'. Not only it is free to use, but uses less resources than the commercial alternative. This results in a user allowing to utilize their computer more when streaming; for example, with XSplit I couldn't stream 1080p/30fps or 720p/60fps smoothly, but with OBS, I can do both without taking as much of a performance hit as with XSplit.



For reference, Quantic.Illusion uses OBS. His stream is one of the most smoothest and best looking streams out there at 3000kbps/720p/60fps. From what I understand, it is being encoded with a consumer-level CPU. With XSplit, these sorts of results can only be achieved with a enthusiast-level CPU or a heavily over-clocked, high-end consumer CPU.

Anyway, let's take a look through the program.



First of all, download the program from

Honestly, if you are planning on streaming, you should have a 64-bit operating system installed. Therefore, there is no reason you should be using the 32-bit version of the program over the 64-bit version, unless you are still running 32-bit Windows for whatever reason.



Install/extract then run OBS. You should be approached with the main screen.



Note that unlike in XSplit, you will have to create scenes manually. To do this;

1. Right-click in the 'Scenes' box.

2. Select 'Add Scene'

3. Name your scene.



Also in this box, you can add a hotkey to quickly switch between scenes. To do this;

1. Right-click the Scene you wish to hotkey.

2. Select 'Set Hotkey'

3. Input the key(s) you wish to use (CTRL, ALT and Shift work in combination with most keys).



Now lets add some sources to the scene. You can do this one of two ways;

1. Adding sources individually to each scene.

2. Adding sources as a global function.



I'm not sure whether either makes a difference, but lets go through both options.

For individual;

1. Right-click on the 'Sources' box.

2. Select which kind of Source you wish to add. Monitor / Window Capture is the OBS equivalent of Screen Region from XSplit, Bitmap is to add an image file (overlay) and Video Capture Device is to add a webcam or third-party screen capturing device (e.g. Dxtory, Camtasia). For games, use Game Capture.

3. Name your source whatever you wish.

For global, click on global sources, then click add. Repeat steps as above.



Once you have added your sources, click on 'Edit Scene' to start adjusting each source (size/placement). A rectangular, red border should come up, where you can begin to adjust the source.



Rinse and repeat for every scene and every source you need to do.

For those that use overlays/webcams, you'll have to mess around with the source priority list. To do this, click on a source, then right-click, and depending on what sources you would want on top/below, you can move them up or move them down.



To see these scenes in effect, click 'Show Preview'. You can adjust scenes while preview is both on or off (it should be on).



Now lets look at the settings menu.

General - Self-explanatory.



Encoding - Self-explanatory as well. See



Broadcast Settings - Unless you are only using OBS to locally record, the mode should be set to Live Stream. Streaming service is self-explanatory, but if you are not using Twitch/Own3d, you'll have to manually input the Channel Name/Stream Key/Server. For those on Twitch, your Stream Key can be found at



Video - Your base resolution should be the resolution of the main monitor you are streaming. If you wish to downscale your resolution for streaming (for example, down to 720p), you can select it with the dropdown. FPS is self-explantory. Aero should be disabled if you are planning to stream with the software capture option.



Audio - All self-explanatory.



Advanced - Do not touch unless you know what you are doing.



Let me know if you found this guide useful. If you have any problems regarding the software itself, I suggest posting in the Some of you may have seen the guide on how to stream with FFSplit, an open-source alternative for XSplit. However, there are some features from XSplit that aren't in FFSplit, such as the ability to do multiple scenes and having multiple sources on one screen.Luckily, there is now a new program that does all of this, OBS, or 'Open Broadcaster Software'.

obs.Jim Profile Joined August 2012 United States 101 Posts Last Edited: 2012-10-01 08:36:25 #5 Wow, thank you very much for writing this guide. I was actually going to do something similar myself after I had polished up the software a bit and officially go into beta, but er.. actually, the reason I haven't really said anything anywhere about the app is because I may had been sort of hoping to sneak in some dark souls and borderlands 2 time in while my emails have died down again, I admit. I was going to do another reddit post when I go to beta (which is looking pretty soon) as well.



The app was nigh unusable a month ago when I made that first reddit post, but fortunately I ironed out every single issue that people have brought up, added a ridiculous number of features, and it's in fact gone far beyond my original expectations.. So I'm pretty proud of it.



This app would be nothing today without everyone who helped test, report bugs, and request features. R1CH as well has been contributing to the project, and his help has been immeasurable. So thank you to everyone for your support.

Also, I know that you quantic guys and many pro gamers use transitioning images to show your team sponsors (you know, where you have multiple sponsors fading in/out on a single area of the screen), so I'll get something in next version for you guys so you can do that. Hm, rare for someone not to have an up-to-date version of directx. But you can get it here - http://www.microsoft.com/en-us/download/details.aspx?id=8109 - I'll also see if I can't somehow make sure directx is up-to-date in the installer.Also, I know that you quantic guys and many pro gamers use transitioning images to show your team sponsors (you know, where you have multiple sponsors fading in/out on a single area of the screen), so I'll get something in next version for you guys so you can do that.

I just tested some stuff and it works really great with dxtory too. Overlay feature when using dxtory doesn't get messed up like in ffsplit. Can use png files as bitmap easily. The only bad thing is For example i put dxtory as a scene and my desktop as another. When i switch scene and go back to dxtory one i have rescale the dxtory window because of downscaling that i use. Doing this everytime changing a scene if you use video output is bad so if there is an easy fix for it it would be great for me too.

Has anyone done a performance test between this and FFsplit ?

Not officially, but i have done several tests with both ffsplit and OBS. The trouble with ffsplit, is that if you don't actually have the processing power, it drops the frame rate, whereas with xsplit / OBS you will actually see a performance hit in-game.



System that i'm testing on:

i5 2500k @ 4.7 ghz

no capture card

radeon 7950 @ 1000mhz





I have done some tests:



FFsplit:

at 1080p @ 45 fps generally works most of the time, usually goes down to 40-30 at the end of a long sc2 game.

720p @ 60 fps works ok-ish, it usually goes to around 40-50 fps



OBS:

Can stream 1080p 60 fps just fine, don't really see any performance hits at all. (usually around 100 fps on medium and high)

720p 60fps obviously works fine.



I don't have the paid version for xsplit, as it is expensive as hell, so can't really do any tests in that respect.



Will provide links when i get back to my main computer (at the weekend).



Please take into account that the VOD's will have a very low bitrate, as my internet is quite bad (only 1mb up). Not officially, but i have done several tests with both ffsplit and OBS.

I've tried reinstalling, to no luck. Any ideas?

Very impressive piece of software. Might makes right.

obs.Jim Profile Joined August 2012 United States 101 Posts Last Edited: 2012-10-01 18:41:35 #18 Yea, I'll see what I can do about potentially getting directx updated via the installer if necessary, though I may have to switch to different installer software to do so, so it may be a while.



As for performance, I would love to see more comparisons being done. Most people are telling me it gets better performance for them than xsplit, and causes less issues for their games. I'm not entirely surprised because the app is written entirely in C and C++ with performance in mind, and I'm normally a game engine developer so I'm very familiar with writing performance critical code where each and every millisecond in each frame matters. Again, I admit I'm pretty proud of it.



WTFZerg - thank you very much. Like I said in my original reddit post, I didn't even know about ffsplit when I was originally making the software. I am just glad there are at least some alternatives to xsplit, regardless of which ones people use. Hopefully we can all learn from each other and just overall make sure there are better alternatives out there for everyone.
