Beginner’s Guide to Streaming on Twitch
Updated August 2018
A lot has changed in streaming since I originally wrote this article earlier this year so I made a number of updates to the article throughout. One big change is the release of Streamlabs OBS which came out shortly after I completed work on this article.
Streamlabs version of OBS actually solves a lot of the technical complexities I have listed below. If you are new to streaming and just wanna get started right away I encourage you to download it and get going.
Streamlabs OBS is free & reliable broadcasting software with the lightest resource footprint on the market. Level up…streamlabs.com
That being said, the rest of this article has a bunch more information. Most of the same tricks and techniques are relevant to Streamlabs OBS as well as normal OBS. I’ve included some more advanced techniques later on such as rounding the corners of your videos, streaming over NDI from a second machine and my thoughts on chatbots. Here we go!
Lately I’ve been fascinated with watching people stream on Twitch. I like the deep cut channels the most, people who have 0–5 viewers. I get to peek into their lives, watch them play games, make things and generally be awkward and bizarre.
For whatever reason, I too feel compelled to participate in this medium and I’ve spend the past few months learning and exploring how it all works. I thought I’d share what I learned so far. One of the most rewarding parts of the experience has been exploring and playing with the tool-set streamers use. It’s a different kind of creativity than I’ve experienced before and it’s really fun.
This is obvious, but you will need an account on Twitch to get started. Follow and friend everyone you know IRL. This will be helpful later on.
Open Broadcaster Software is very capable software to broadcast your stream to Twitch. I’ll walk you through the basics of what you need to know.
- Download OBS and install. If you are using Windows, right click on OBS and ‘Run as Administrator’ so it automatically grants the software permissions to capture your games.
- Open Settings and select ‘Stream’. Select Twitch as the ‘Service’.
- Open Twitch in your browser and select ‘Dashboard’ from your menu in the upper right corner. Select ‘Settings’ from the left nav, then select ‘Stream Key’. Tap ‘Show Key’.
- Paste the key in the OBS field called ‘Stream Key’.
- Congrats, you can technically start streaming now!

OBS and SLOBS (Streamlabs OBS) will be used interchangeably throughout this article. I did want to take a moment to point out their relationship to each other as well as their differences.
OBS is powerful open source software and if you want the most amount of flexibility it is probably the right choice for you. SLOBS is a version of OBS that is still normal OBS, but the company Streamlabs have added a new interface to make it easier to use as well as providing additional features like built-in chat, pre-designed themes for your stream, and facemasks. Another advantage SLOBS has over OBS is encoding is not only easier to set up but also higher quality in many cases.
One distinct advantage OBS has over SLOBS is its use of plugins as I will mention later in the article. Regardless of what you choose to use, you can go back and forth between them fairly easily. SLOBS will import your settings from OBS, but in many cases you will need to recreate your work in OBS if you do it in SLOBS first because it supports additional features by default.
Something to Stream
Maybe you want to stream games, maybe you want to stream yourself working or maybe you just want to stream yourself on camera. You need something to stream. Here is how you set that up:
It is likely that you are interested in streaming games. If it’s not games you are interested in, most desktop applications can also be streamed using this same technique:
- Go to the sources panel in OBS and press the + button. Choose ‘Game Capture’ and enter the name of the game or application you want to stream in the ‘Create New’ field.
- Open the game or application and select ‘Capture Specific Window’. Press OK.
- Choose your application in the Window drop-down. Press OK.
You will want this source at the bottom of your ‘Sources’ list. The list mimics the visual hierarchy of sources and you are going to want to overlay other sources on top. You may need to resize the source. You can do this by dragging a corner of the source and snapping it to the edges of the full window.
Maybe you just want to stream your whole workspace. I usually don’t do this because it feels pretty dangerous. I prefer to not broadcast open browser windows and such, but if you like living on the edge you can stream everything your computer is displaying using this technique:
- Choose ‘Display Capture’ as your source.
- Enter a name and press OK.
One of the main enjoyments of watching a stream is seeing someone react and express themselves. I highly recommend streaming with a camera.
This may feel awkward at first but you will get over it. It’s really no different than how you present yourself all day long. Just be yourself.
- Choose ‘Video Capture’ as your source. Name it ‘Camera’.
- Choose your camera and press OK.
- Place the source above the Window Capture in the sources list and resize the source to your liking.
In most cases, you will also need to add your microphone as a ‘Audio’ source.
OBS Stream Settings
This section is likely to be the most contentious information I provide. OBS stream settings are a bit like black magic. The best settings vary widely with people’s particular setups. Serious streamers use a second computer to encode their streams so they don’t eat up resources from their main device.
I’m going to share with you my settings, which work for me. I encourage you to go check out the thousands of videos on YouTube about various other setups if you don’t find these to work to your liking.
- Open OBS and choose ‘Preferences’.
- Tap the ‘Output’ category.
- Set your ‘Video Bitrate’ to 3500.
- The ‘Encoder’ should be set to be ‘Software (x264)’.
- ‘Audio Bitrate’ will be 160.
- Set your ‘Output’ to 1280x720 with bicubic downscaling at 60fps.
These settings are fairly conservative but I think they are a nice balance point of performance and quality. I prefer frame rate to resolution but in certain situations you might prefer the opposite. Some streamers push a significantly higher bitrate, but keeping your bitrate lower makes it easier for people to watch your stream, especially on lower bandwidth connections.

The above settings are what I use for OBS, when using SLOBS I end up just using the settings it sets up for me automatically.
2. Advanced Tools
With the basics out of the way, you can proceed in your streaming and probably have a good time, but the rest of this article is where I think all the fun is. Let’s add some functionality to our stream:
Overlays let you place data on top of your stream. The point of an overlay is to give your viewers more information to latch onto so they don’t get bored and leave if the stream gets dull.
You can theoretically do anything but certain overlays are more obviously advantageous. Think of them as similar to how news tickers or sports statistics keep your mind active as a viewer.
I believe putting some sort of unique mark on your stream helps you initially express a bit of personality but also allows your viewers to instantaneously recognize that you are serious enough not to be doing this by accident. To add a static image overlay:
- Go to the ‘Sources’ panel, tap + and choose ‘Image’.
- Name the image source and press OK.
- Select the image from your local drive and resize.
Unless you specifically want a rectangular image, you will want to choose a PNG image with transparency. This can be created in most image or design tools.
You can use this same technique for any sort of image. For example, I like to put little stickers of the people who I am playing with next to my video so people can have an idea of who are the voices on the stream.
Update August 2018
The instructions for ‘alerts’ below are for normal OBS. If you want to set up these kind of alerts in SLOBS, they are built into the product.
If someone follows you, alerts allow you to celebrate it in real time with your viewers. You can let the person know you appreciate the attention and also let them bask in the glory of interacting with the televisual in real time.
The best service I have found to set up alerts is Streamlabs. This is a separate site which you can log into with your Twitch account. Here’s how to set up your alerts:
- Tap ‘Widgets’ in Streamlabs left panel.
- Tap ‘Alert Box’.
- Press ‘Copy’ next to ‘Widget URL’.
- Open OBS and add a new source for ‘BrowserSource’. Name it ‘Alerts’ and press OK.
- Paste the URL into the URL field and press OK. Position and resize the source in the main view.
This will get your alerts working. You can test by pressing ‘Test Follow’ in the Streamlabs Alert Box page. You should see the alert show up in the OBS view with a sound.
The entire Alert Box interface can be fully customized from the Streamlabs interface. You can choose fonts, colors, animation styles, etc. These customizations can even be set up for specific type of alerts. ‘Subscriptions’ can be more special than ‘Follows’ for example.
You can also use Streamlabs for a variety of other overlays such as a recent activity list, goals, chat box and viewer count. Take a peek through their widgets and set up ones that make sense for your stream. Adding these sources of activity to your stream can be helpful to show your viewers what you are interested in and also a source of things to chat about.
If you like to listen to music while you are streaming check out Snip (Windows only). Snip runs in the background and can create text and image overlays of the current song and artwork from many music services and apps such as Spotify and iTunes.
- Download Snip. Expand the package and launch the application named ‘Snip’.
- In your taskbar, right-click on Snip. You can select your service here.
- Play some music and Snip should generate a file in it’s directory called snip.txt as well as an image file named Snip_Artwork.jpg.
- In OBS create a new ‘Text’ source. Let it read from a file and select the snip.txt file in the Snip folder. You can format how the text is displayed in OBS.
- If you would like a thumbnail as well, you can create a new ‘Image’ source and select the Snip_Artwork.jpg file.
There are also other cool options to Snip, such as breaking out the metadata into separate files which allows to set up layouts like the one I use. You can do this by selecting ‘Create Separate Files’. Snip also supports useful hot keys in the settings.
You may have noticed you can quickly get overwhelmed with all the possibilities of these sources. That is what ‘Scenes’ are for. In OBS you can set up multiple scenes that you can switch to on the fly during your streams. I have 4 main scenes I use:
I use this one for games that have little information in the lower right corner.
I use this one for games that have little information in the lower left corner.
This makes my camera the full size of the screen and reduces the game to a smaller overlay size. If I am talking a lot or waiting for a game to load I can switch to this one for a break in the stream without losing context of what I’m doing.
I use this screen when I need a break. I keep many image sources in this scene for different games I play so I can fire up the relevant BRB images.
I also set up scenes for certain games that I’m playing a lot which allows me to customize the layout specifically to the game’s UI.
Within scenes you can always toggle on or off a layer’s visibility by tapping the eye icon. When I get a scene laid out properly, I like to lock all the layers that I won’t be moving with the lock icon. This prevents me from screwing up scenes inadvertently.
You can also set the transition that occurs between scenes in the ‘Transition’ panel. I generally find that a quick cross-fade works pretty well, but you can also create more exciting animations. OBS even supports video stingers which allow you to create totally custom transitions.

Rounded Corners for Video
I thought it would be cool to have rounded corners on my video. I found a plugin that only works on normal OBS called Shaderfilter. It’s not the most intuitive tool, but it’s very powerful for affecting elements of your stream.
obs-shaderfilter - OBS Studio filter for applying an arbitrary shader to a source.github.com
The key to getting it work is to set the ‘shader text file’ as an effect on the video you want to round the corners of. There is a longer explanation video which I watched to learn how to do this.
I tried out a bunch of chatbots for my chat but most of them are mainly useful for very active chats. Something that did provide me immediate value is Chatty (Windows only). Chatty is so full of features it’s hard to describe. Here’s how to set it up:
- Download Chatty (standalone version) and install on your machine.
- Log into your Twitch account through Chatty.
- Choose your channel name, which is your Twitch username and connect.
- Make sure to select ‘Rejoin Open Channels’ so whenever you open Chatty it will reopen your chat.
Since I only have one monitor, I wanted to avoid switching in and out of my game as much as possible. I set up notifications for new chat messages as well as when people joined my chat (tutorial). I can see these notifications over my game view and respond to them accordingly. I also added sounds to certain notifications so I wouldn’t miss them.
I also use Chatty’s Admin window to set up my stream information such as the title, the game I’m playing and associated communities. I use the Info window to keep track of how many viewers are in my stream over time. You can think of Chatty as a native replacement for using the Twitch dashboard.
Chatty can do so much more: moderation support, highlighting certain viewers in chat, and viewing all messages of a specific chatter. Play around with this one and see what it can do for you.
Update August 2018
Although Chatty is really powerful, I’ve mainly switched my chat to Streamlabs Chatbot. If you’ve invested in Streamlabs tools and ecosystem, it is pretty advantageous to use this tool since their features are available here.
You can use a ‘Media’ source to set up scenes of video playback. This can be used to play intro, outro or transitioning video content in your stream.
Twitch has a feature called Extensions. Developers can create extensions that you can enable on your stream. These extension allow interactions or display of data. For example, a viewer can look at your Destiny 2 loadout with the Destiny 2 Armory Overlay.
Another important experience to consider is your profile. People might come across your stream but not be sure why they should care about you. Indulge them with some good information to sink their teeth into.
I include an about section, games I am currently playing, my friends who also stream, other social profiles and information about my setup. I’d err on the side of overindulgence rather than being shy. People are looking at this area to find out more about you, give it to them.
You can customize the look of this section by creating graphics. There are tons of pre-made templates out there if you are overwhelmed by that task, but I think it’s pretty fun to create your own to match the visuals in your stream.
It’s also important to consider the experience of your channel when you are not streaming. I recommend going to your ‘Channel & Video’ settings and auto-hosting your friends or other streamers you enjoy. They might even auto-host you back.
In the case that no one you are hosting is streaming you can also set up a custom Video Player Banner. This is also in your ‘Channel & Video’ settings and it is a 16:9 image that is shown in the spot of the video player when you are not online.
Everyone says getting a streaming audience is real hard. I am in no way an expert about this since I haven’t built much of an audience beyond my friends yet, but here are the tips I’ve heard researching what other people have to say about the topic:
It feels very awkward to keep talking even when no one is watching but it’s actually really important. Someone can jump into your stream and see you sitting around quietly staring at your screen and leave right away. This might happen before you even get notified that someone is there.
If you are talking and they jump in, they will get a better sense of who you are and may be compelled to stick around a while longer. People say once you get used to this stream of consciousness it becomes easy. I really enjoy the challenge of thinking that way and I think it will give me more confidence in speaking in general if I can get good at it.
Meet other like-minded streamers. Get to know them. Learn from them. Streaming is a community just like any other community and people want to help and learn from each other.
If you are playing with friends, ask them if you can include their Discord audio in your stream.
One issue I’ve already noticed is the awkwardness that can occur when responding to your Twitch chat while being in a voice channel with your friends. I got a tip from my friend Hauz to set up a universal hot key for muting your mic in Discord.
I set up Control-Shift-2 to mute my Discord mic, so when I want to respond to someone on the stream I hold those keys down. You can obviously set up a simpler quick key but I liked keeping my left hand in the same position as when I’m gaming.
Now that you are excited about streaming, maybe some of your friends also got excited about streaming, and now the rest of your friends don’t know who to watch since everyone is streaming. Multistream lets you create layouts of multiple streams at once. You can share a custom link and let people view the action from multiple angles.

Streaming via an Additional Machine over NDI
I have a second PC and I wanted to try streaming from it instead of my gaming PC so I could save system resources for my games. The streaming PC is in another room and I didn’t want to spend money on a capture card so I figured this wouldn’t be possible.
Then I found an interesting plugin for OBS which allows me to broadcast my stream over my local network with a technology called NDI.
This plugin adds simple audio/video input and output over IP using NewTek's NDI™ technology. Three integrations are…obsproject.com
On the streaming PC, I have Streamlabs OBS set up and it is receiving the NDI signal and doing the encoding and broadcasting. I access the streaming PC from my normal PC using Remote Desktop to start and stop the broadcast. Check this video out for more info.
I hope this information helps you get started with streaming on Twitch. It’s such an enjoyable process to customize your stream and profile once you get past the technical hurtles and find the right tools.
If you’d like to watch my stream or just hang out, you can follow me at twitch.tv/gargarbot. I’ve been streaming games like Destiny 2, PUBG, Overwatch and older classics like Tetris. I’m also going to try dabbling in doing some game level design live in Unity and Unreal Engine.
Thanks for reading!
