This guide assumes you already have a basic knowledge of streaming services and streaming terminology, and aims to give you a quick overview of the most important options and features in OBS Studio. However, even if you don't have any previous experience, don't be discouraged! This guide can still be very useful. It may seem like a lot to take in all at once; just take your time and read carefully.

This guide is broken into these main sections:

Quickstart

Getting started with OBS Studio is relatively simple, with only a few steps needed before you're on your way to creating content.

  1. Select your Streaming Service in Settings -> Stream, and enter your stream key information. If you are only going to be recording, you can ignore this step.
  2. Select your Base (Canvas) and Output (Scaled) resolutions and FPS in Settings -> Video. The Base (Canvas) should be set to your primary monitor's resolution by default, and this is usually safe to leave alone. Output (Scaled) is the resolution that the stream or recording will be output as. For most cases, we recommend starting with 720p (1280x720) at 30 FPS as the starting point.
  3. Set your streaming bitrate or recording quality in Settings -> Output:
  • For Streaming, set the bitrate you wish to stream at. Recommended for 720p 30 FPS is 2500. If your internet cannot support this much bitrate, you may need to downscale resolution further to accommodate a lower bitrate.
  • For Recording, select a Recording Quality from the dropdown menu. Indistinguishable Quality is our recommended starting point. If you have an available hardware encoder (NVENC, QSV, or AMF), you can select that here as well.
  1. Add your Scenes and Sources for the content you wish to stream or record.
  2. Click on Start Stream or Start Recording, and enjoy!

New This Version

OBS Studio 19.0

General Changes:

  • Added an auto-configuration wizard to the tools menu and on first-time use, which will attempt to automatically test and configure video/encoding/streaming settings based upon your system and internet connection. This wizard is currently in beta and may be subject to change, feedback is appreciated.

  • Added a "Render Delay" filter that allows delaying non-async video sources such as display capture or window capture. Note this is only meant for minor sync adjustments (e.g. syncing your screen capture to a webcam), and because the delayed frames are stored on very limited VRAM, the allowable maximum delay is 300 milliseconds (which is 150 megabytes of VRAM at 1080p 60 FPS)

  • Added a stats dialog to the view menu (with the option to show it on start it up in general settings). The stats dialog shows advanced statistics, such as: average frame rendering time, frames lost due to encoding/rendering/network lag, HDD space left in recording location, and how much data has been output total.

  • Added the ability to copy and paste filters between sources

  • Added an option to the blackmagic source that allows you to set the channel format to capture at (stereo, 5.1, 7.1)

  • Added Ctrl-E as a shortcut to edit transform of sources

  • Added a command line option to start as always on top (--always-on-top)

  • Added a "shuffle" option to the VLC video source

  • Added specific error messages displayed to the user when fail to connect

Full list of bugfixes and other minor tweaks can be found here: https://github.com/jp9000/obs-studio/releases/tag/19.0.0

Linux Changes:

  • Added the auto scene switcher to linux

Settings

OBS Settings Window

Overall, most settings will be fairly self-explanatory. This will not cover everything, but will be an overview of the basics and what you can do in each section.

General

  • Change theme (light/dark)
  • Enable/disable system tray icon (required for hiding to tray)
  • Show confirmation for starting/stopping streams
  • Enable/Disable Source snapping
  • Enable/Disable automatic recording when streaming

Stream

  • Select one of the included Services (Check "Show all services" to see the full list in the dropdown) or set Custom Streaming Server
  • Select the server (or enter its URL for Custom Streaming Servers)
  • Enter your Streamkey

Output

Note: This section covers Simple output mode. Advanced output mode gives you further options to configure your Stream and Recording independently if you want to. We will not be covering advanced options in this guide (see links at the end). Generally, unless you know why you need to change it, the default options are recommended.

For Streaming:

  • Set your Video Bitrate. This changes according to your upload speed and the limitations of the service you use (for example, 6000kbps max for Twitch.tv)
  • Set your Audio Bitrate. Around 160kbps for streaming, or lower if you have a low upload speed

For Recording:

  • Set your Recording Path
  • Record using a preset (Same as stream, High Quality, Indistinguishable Quality, and Lossless) and a different Encoder (if available)
  • Select a Hardware Encoder if available (only if you use a different preset than "same as stream" and if a Hardware Encoder is available)[QuickSync, NVENC or AMD VCE]
    • Encoder option will not show up until you select a recording quality other than Same as stream
  • Enable the Replay Buffer (hotkey to save the buffer must be set under the Hotkeys section)

Audio

  • Change the Sampling Rate
  • Select up to two Desktop Audio Device's
  • Select up to three Microphone/Auxiliary Device's
  • Enable Push-to-mute or Push-to-talk for each device (keys configured in the Hotkeys section)

Video

  • Base (Canvas) Resolution
    • This is the amount of space you have to fit your sources. You usually want this to match your monitor display resolution, or if you are playing games, the game resolution. Default is your primary monitor.
  • Output (Scaled) Resolution should be the Stream Output Resolution (720p,480p,etc)
    • This is the resolution that the stream/recording will output at, using the selected downscale filter. If you have 1080p sources, but want to stream at 720p, this is where you would set that.
  • Common FPS Value should match your desired output FPS (30/60 for example)
    • Note that 60fps streaming can be very taxing on your system compared to 30fps. Test ahead of time and ensure your system has enough resources available.

Hotkeys

Here you can set hotkeys that do a variety of things. Some examples:

  • Start/Stop Streaming/Recording
  • Hide/Show Sources
  • Switch to a specific Scene
  • Push-to-talk/Push-to-mute
  • Capture active window for Game Capture
  • Start/Stop/Save Replay Buffer

Keyboard keys are supported. To use joysticks as hotkeys on Linux and Windows, you can use antimicro to map the joystick keys to common keyboard keys and then use them in OBS.

Advanced

Most of these settings should not be changed unless you understand exactly why you need to change them. However, some settings can be useful for new streamers, such as:

  • Change the Filename Formatting (or use folders: %CCYY%MM%DD%hh-%mm-%ss = 2016 \ 07 \ 10 \ 12:35:25.flv)
    • Hover over the field for a popup that explains each available variable for naming
  • Activate Stream Delay
  • Configure Automatic Reconnect
  • Do not touch anything else in Advanced unless you absolutely know what you're doing. Really, we mean it. If you have questions, search around or hop in the support chat and ask!

Scenes and Sources

Scenes and Source

Scenes and Sources are the meat of OBS Studio. These are where you set up your stream layout, add your games, webcams, and any other devices or media that you want in the output.

Right click in the box under Scenes (or use the plus at the bottom) to add a scene if there are none listed yet. You can create as many Scenes as you want, and name them to easily distinguish between them. For example: Welcome, Desktop, Game, Break, End. The arrow buttons can be used to change the order. As an important note, all Scenes and Sources are global in OBS Studio, so they can not share a name. This means if you name a source Game, you can't have a Scene with the name Game.

Once you have created a Scene, right click in the Sources box (or use the plus at the bottom) to add what ever you want to capture. Whether it's a specific window, a capture card or game, image, text or your entire display that you want to capture, there are several different sources available in OBS Studio for you to choose from. Try them out!

Sources List

You can re-align sources in the preview and change their order by using drag and drop in the list, or using the up and down arrow buttons. A Source that is listed above another Source in the list will be on top and might hide what's beneath it. This can also be useful for situations where you want something on top of another source, like a webcam to show over your game play. Any time you see an eye icon, you can click it to show or hide the associated item with it (this applies to filters as well)

Visible: Visible

Hidden: Hidden

When a Source is selected in the Sources list, you will see a red box that shows up around it. This is the bounding box, and can be used to position sources within the preview as well as make the source larger or smaller.

Source with bounding box

If you need to crop a source, hold the Alt key and drag the bounding box. The edges will change to green to show it's being cropped. You can see both techniques being used here to crop and enlarge only the part of the screen we want to show:

Cropped Source

If you later on change the Base (Canvas) Resolution of OBS Studio, you will have to re-align or re-size the sources. Changing the Output (Scaled) Resolution does not have this effect.

The following Hotkeys are available in the preview to tweak the source position and size:

  • Hold CTRL to disable Source/Edge snapping
  • Hold ALT to enable cropping
  • CTRL+F for fit to Screen
  • CTRL+S for stretch to Screen
  • CTRL+D for center to Screen
  • CTRL+R to reset a source size/position

You can also right-click each source in the list to access further options. This is also how you access filters, which is discussed in the very next section!

Right Click Menu

Edit Transform menu:

Transform Menu

Filters

Filters Window

Filters can be added to each Source/Audio Device, and even to a Scene. You add a filter by right-clicking onto the desired Source or Scene in the list, and then selecting Filters. For Audio devices, click the little cogwheel next to the volume bar in the Audio Mixer and select Filters. Clicking the eye icon next to an added filter will enable/disable that filter, similar to showing/hiding a source. See the Filters Guide link for a more in-depth guide on Filters and their specific function.

List of Effect Filters:

  • Image Mask/Blend
  • Crop/Pad
  • Color Correction
  • Scaling/Aspect Ratio
  • Scroll
  • Color Key
  • Sharpen
  • Chroma Key

List of Audio/Video Filters:

  • Gain
  • Video Delay (not available for Window, Display, or Game Capture)
  • Noise Suppression
  • Noise Gate

Studio Mode

Studio Mode

Studio mode can be a bit confusing. First, let's understand what the purpose of Studio mode is.

Activating Studio Mode allows you to change your Scenes in the background without your viewers being able to see you making those changes. After you click on the Studio Mode button, you will see the current Live Scene (what your viewers see) on the right while your edit Scene on the left.

After you are done editing the Scene you can click on "Transition" (or use a Quick Transition/Hotkey if you added one) to swap the left and right, making the Scene you were editing the live Scene. If you are changing Scenes, the last active Scene will be shown in the edit area on the left. After you are done with everything and transitioned to the changed Scene, you can deactivate Studio Mode until you need to edit again. Viewers cannot see when Studio Mode is enabled or not.

Scene Transitions

Some Transitions in OBS Studio are available from the first launch: Fade and Cut Transition. You can add more using the plus button in the Scene Transitions section. Currently Swipe, Slide, Fade to color, and Luma Wipe (with several wipe options) are available. More may come in the future.

You can switch the currently active Transition with the drop-down menu and change its duration.

After you have configured a Transition, you can also add it as a Quick Transition in Studio Mode. For Quick Transitions, you can configure the duration(length) of the transition as well. For example, you can add the same Fade to your Quick Transitions Menu with 500ms and 1000ms if you wanted. Also, you could configure a Swipe left and a Swipe right transition, then add them both as Quick Transitions and use them to first swipe left in your Scene A to change Scene B, and then swipe right back to your newly configured Scene B when you are done.

Testing

There are many more options and functions inside OBS Studio, but I hope you got a good idea of the different things that are possible with this great tool.

Test, test, test!

Now it's time to start testing! Are the settings working? Is the stream running smooth? Are all your Scenes configured how you want them? It's strongly recommended that you test everything as best as you can before starting your first live stream. This can help work out any kinks or performance issues you might be having ahead of time, and save the embarrassment of any issues on the stream itself.

If you have problems, start a thread in the Support section of the forums. Be sure to include a log file. Alternately, you can join our community chat to get live help from community volunteers.

If you want more control over your Recording settings or want to record multiple audio tracks, switch the Output Mode to Advanced and check out this guide: High quality recording and multiple Audio Tracks
