    What is OBS Studio Used For?

    obs studio 27.0.1
    OBS Studio is a great software encoder option and has many use cases. A simple setup is required before you can get started.

    OBS Studio is a free, open-source streaming software that many broadcasters use for mixing and producing live video content. The latest version of OBS Studio, Version 27.1.4 was released on March 29th, 2022. It is available for macOS 10.13 or newer, Windows 8, 8.1, and 10, as well as Ubuntu 18.04 operating systems. For the Linux version, FFmpeg is required.

    Some of the main functions of OBS Studio are encoding, screen recording, adding text and graphic overlays, managing multiple stream sources, and more. OBS operates with community-developed plugins, which you can find on the OBS Forums page.

    Since OSB Studio software is free, we often recommend that new broadcasters use OBS Studio to experiment and learn the ropes of video production. 

    How to Use OBS Studio

    In order to use all of the functions of OBS Studio, you have to set up OBS to flow with your streaming setup. Luckily, the OBS Auto-Configuration Wizard is available to automatically determine the proper settings for your computer and streaming solution. The OBS Auto-Configuration Wizard makes using OBS for streaming video simple for beginners. 

    Even with the OBS Auto-Configuration Wizard tool, there are a few manual configurations that you’ll need to set up to use OBS for streaming. That said, let’s run through the process of setting up OBS Studio:

    1. Download OBS Studio
    2. Run the OBS Auto-Configuration Wizard to find optimal settings for your system
    3. Manually adjust suggested settings if necessary
    4. Setup your audio devices: “Settings” > “Audio”
    5. Add a source: “Sources” > “+” > choose your source
    6. Confirm that settings are properly: “Settings” > “Output”
    7. Test your stream by clicking “Start Recording” or “Start Streaming”

    Check out the OBS Studio Quickstart Guide for more information on how to use OBS.

    With that general process in mind, let’s take a look at how to use the different functions of OBS Studio, such as adding a video source, screen recording, incorporating graphic overlays, and more. Let’s dive into how to use OBS for streaming. 

    How to Add Video Sources on OBS Studio

    One of the simplest and most important tasks with OBS is to add video sources to your stream. Video sources include things such as webcams or digital cameras. 

    This is how to set up sources on OBS.

    To add a video source, such as a webcam or a camera connected via a capture card, first, plug the device into your computer. Then, click on the “+” sign that is inside the “Sources” widget:

    Add Video Sources on OBS Studio

    • This will generate a drop-down menu with three different choices: Display Capture, Window Capture, and Video Capture Device.
    • Select “Video Capture Device” to add a camera.
    • Then you will be asked to name your video source. You can add an existing one or create a new one
    • At this stage, you can also choose to flip the image vertically or horizontally, adjust the opacity, change the resolution, or set up a chroma-key (green screen) effect. 
    • When you are done click “OK,” and your video source will be added.

    If there is blank space bordering your video feed, you may need to go to “Settings” and adjust the resolution of your broadcast to match the size of your video input.

    That is how you select a source in OBS.

    How to Use OBS Studio Window Capture

    If you want to share your computer screen during your broadcast, you can either use Display or OBS Window Capture. Let’s go over how to use window capture. 

    Display Capture will broadcast everything that is on our computer screen in a certain area, although the size of that area can be changed. Window Capture for OBS will allow you to broadcast the screen of a particular application (Skype, Word, PowerPoint, Internet Browsers, etc.) and only that.

    • To set up a Display Capture go to the “Sources” widget, click on the “+” sign and select “Display Capture.” 
    • Give it a name and click “OK.” 

    From there, you have the choice of whether you want the mouse cursor to be captured or not. You can also set the opacity and select a “Sub-Region” to create a smaller area of your monitor screen to capture:

    • OBS window captureFor Windows Capture go to the “Sources” widget, click on the “+” sign and select “Window Capture.” 
    • Name the source and click “OK.” 
    • On the drop-down menu, select which application you want to OBS Window Capture from. If you don’t see the one you wanted, try re-launching OBS or the program (or both). If it still doesn’t appear, use “Monitor Capture” instead.
    • Choose whether you want to capture the Entire Screen or the Inner Screen. You have the option to choose if the mouse cursor is captured or not, the opacity, and create a smaller sub-region. 
    • Click “OK” when you’re done.

    This is how you record a window on OBS and how to get OBS to show your screen when recording a video.

    How to Add Images or Text with OBS Studio

    It is easy to add images and text to your OBS streaming set-up. 

    Here is the easiest way to add images to your OBS stream.

    • To add images to your stream, right-click under sources, then click “Add.”
    • From there, select “Image.” This will give you the option to browse for the image you want to add and adjust the opacity.

    Alternatively, you can add an image slideshow and select several individual files or an entire folder.

    The process to add text to your OBS stream is very similar.

    You can use the menu settings to choose color, opacity, font, size, and message text. Also, you can indicate whether or not you want the text to scroll, and you can set the scroll speed.

    How to Arrange Multiple Video Sources on OBS Studio

    OBS allows broadcasters to create scenes with more than one input on the same screen. This allows you to create professional picture-in-picture broadcasts and bring in multiple guests/videos via multiple video sources.

    After adding a source, you can position it anywhere you like. To move a source, just click on it, and resize and reposition it the way you want:

    OBS Multiple video sourcesYou can also do a right-click on your video source to change the order, rotate them, or even add filters.

    If you want to rearrange the layering of your sources, go to “Order” and then select “Move up,” “Move Down,”Move to Top” or “Move to Bottom.” Whatever is on the top layer will cover the sources behind it, with the bottom layer at the back.

    To add a filter:

    • Right-click the video source,
    • Select “Filter”
    • Choose the type of filters you want to add.

    You can choose from a video filter, audio filter, or effect filter on the image. 

    For example, below is an example of an image blend filter and a color correction filter added on the video capture device source:

    OBS studio filtersTo remove anything that has been added in your OBS Studio software—a filter, a video source, or an audio source—just click on the “eye” icon to mask it. For instance, after clicking on the “eye” icons of the effect filters previously added, my video source is back to its original state:

    OBS effect filters for video capture device

    It is easy to learn how to set up OBS for streaming and customize the layout.

    How to Set Up Hotkeys on OBS Studio

    Hotkeys are a key feature for OBS Studio that will help take your streams to the next level. 

    Essentially, setting up hotkeys allows you to switch between multiple scenes instantly, at the touch of a button. For example, if you have ever used CTRL+C to copy something on your computer, you have used a hotkey.

    With OSB, the use of hotkeys allows for smooth, precisely-timed cuts between different pre-recorded or live video streams.

    If you’ve followed our instructions above, you’ve already created your first scene.

    To use hotkeys, start by creating another scene, by clicking on the “+” within the “Scene” widget:

    How to Add a Scene in OBS Studio

    You can set up hotkeys for switching between video streams, using filters, and other functions. OBS has some basic commands already established as hotkeys, such as:

    • Copy source              Ctrl+C
    • Past source               Ctrl+V
    • Remove source         Del
    • Fit to screen               Ctrl+F
    • Stretch to screen       Ctrl+S
    • Center to screen        Ctrl+D

    This will make it easier to learn how to stream on OBS and create engaging broadcasts. 

    Choosing the Right OBS Studio Encoder Settings

    Now that you’ve created your scenes and set up your video sources, you’re almost ready to begin broadcasting. Double-check to make sure your encoder settings are correct. 

    Dacast has a few required OBS studio settings that apply to OBS Studio and any other encoding software you may use.

    These are the required settings:

    VIDEO CODECH.264 (x264 may work)
    FRAME RATE25 or 30
    KEYFRAME INTERVAL2 secs (or 2x frame rate)
    AUDIO BITRATE128 kbps
    AUDIO CHANNELS2 (Stereo)
    AUDIO SAMPLE RATE48 kHz (48,000 Hz)

    Check out our live encoder configuration post for a complete list of suggested settings to optimize your audio and video streaming.

    We recommend checking out our OBS Studio video tutorial for a visual recap of this step-by-step walkthrough of how to use OBS Studio. 

    Streamlabs OBS (SLOBS) vs. OBS Studio

    Streamlabs OBS is another open-source project that functions similarly to OBS Studio. Both of these tools are great for professional broadcasters, but there are a few notable differences between the two.

    In general, Streamlabs OBS has more automated features, making it easier to use. However, OBS Studio supports some more advanced functionalities.

    Streamlabs OBS offers access to some premium features, such as a Streamlabs App Store, Naming Cloud Bot, extra storage, and more. Also, Streamlabs has multistream capabilities and is one of several multistreaming platforms that supports this feature. However, these features can only be accessed with a paid Prime subscription to the software.

    Like OBS Studio, Streamlabs OBS can be downloaded for free, but the Streamlabs OBS Prime membership costs $149/year or $19/month. OBS Studio is free forever, so it is certainly worth trying out.


    Once your streaming software is all set up and you’re familiar with all of the features that OBS Studio has to offer, run a test stream to make sure your broadcast looks and sounds the way you want.  If it all works the way you’d hoped, you’re ready to go. You can use the OBS studio platform to broadcast content from webcams, cameras, and even record and share the contents of your screen. 

    Using OBS with Dacast is a great option if you want to stream live video on your website since it is fully loaded with the features you need to run a professional-grade broadcast.
