OBS – Scenes and Sources

Scenes and sources within OBS are fairly simple to add, and highly customizable. Generally, we recommend that you add as little dynamic content such as screen regions as possible due to the fluctuating nature of whats on your screen. Broadcasting a game directly or through a window is the recommended setup, although this is not compatible with every game or system.

  1. To add a scene, right click the blank space under “Scenes” in the main OBS window, then click “Add Scene”
  2. Enter a descriptive name such as “League of Legends in Game”

Next, make sure you have your scene selected, and right click the white space under the Sources header.

Source: Window Capture
1. Make sure that Aero is enabled, as this will not capture a specific layered window if not enabled.
2. Add a descriptive name like “Microsoft Paint”
3. Window: Under the window dropdown, select the correct program. In our example, it will be Untilted – Paint.
4. Innter/Outer Window: We want to select the header/title as well as whats inside the box, so we will select Entire Window. If you don’t want the outside edge of the window, select Inner window.
5. Capture Mouse Pointer: Check if you want a mouse pointer in the source.
6. Compatibility mode: This generally is for when you don’t want certain programs being caught with your stream. Leave this unchecked unless you have programs with 3rd party programs like Stream Privacy or performance issues.
7. Gamma: You can adjust the gamma of the scene. Recommended to leave this at 1.
8. Use point filtering: Use this if you are wanting to upscale your source in OBS only.
9. Opacity: You can set the transparency/opacity of this source in OBS. Sub Region:
10.Sub-Region: This is an option to capture only a certain portion of a window. Check this if you only want part of a window, such as the drawing portion. We will leave this unchecked since we want the whole window as previously noted.
11. If you do want it, you can select the region using the mouse pointer, or select the coordinates manually.
Color Key:
1. This is also known as a chroma key. Use this to select parts of windows based on their color.
2. Color: Select the color you want to select in your window
3. Similarity 1-100: Select the similarity. IE blue to sky blue, royal blue, turquoise, etc.
4. Blend: Select the sharpness of the chroma key edges.Finishing up and looking at it:

  1. Click “Ok”
  2. Click “Preview stream” on the bottom right button menu in the main OBS screen. Note that the window is not taking up the entire screen.
  3. Click “Edit Scene” on the bottom right button menu in the main OBS screen.

Example of our Paint Window Capture:

Source: Monitor Capture
Monitor Capture is a capturing tool that allows you to capture a monitor’s output. This is useful for quickly getting started streaming, but is generally not recommended outside of ease of use due to several security (information shown) and production issues. Do NOT use Aero when using this as a primary capture means, as it has significant performance drawbacks when using Aero.
1. Monitor: Select the monitor you’d like to capture, listed by number.
2. Capture Mouse Pointer: Check if you want a mouse pointer in the source.
3. Compatibility mode: This generally is for when you don’t want certain programs being caught with your stream. Leave this unchecked unless you have programs with 3rd party programs like Stream Privacy or performance issues.
4. Gamma: You can adjust the gamma of the scene. Recommended to leave this at 1.
5. Use point filtering: Use this if you are wanting to upscale your source in OBS only.
6. Opacity: You can set the transparency/opacity of this source in OBS.
Sub Region:
1. Sub-Region: This is an option to capture only a certain portion of a window. Check this if you only want part of a window, such as the drawing portion. We will leave this unchecked since we want the whole window as previously noted.
2. If you do want it, you can select the region using the mouse pointer, or select the coordinates manually.

Color Key:
1. This is also known as a chroma key. Use this to select parts of windows based on their color.
2. Color: Select the color you want to select in your window
3. Similarity 1-100: Select the similarity. IE blue to sky blue, royal blue, turquoise, etc.
4. Blend: Select the sharpness of the chroma key edges.Finishing up and looking at it:
Finishing up and looking at it:

  3. Click “Edit Scene” on the bottom right button menu in the main OBS screen.

Below is a screenshot of an example monitor capture.


Source: Image
Images are generally static media that are typically used to generate backgrounds, or “fancy” text. Add one by right clicking under Sources, and then make a name. In our example, we’ll call it “Image.”
1. Browse…: Browse your computer for the image file you’d like to add to a source.
2. Color: If the image has transparency effects, select the background color. In our demonstration, I’ve added an image with transparency and selected a blue color for it. Double click on the color box to add a color.
3. Check for file changes: Select this if you want OBS to check for a change in the file and update the scene accordingly.

Color Key:
1. This is also known as a chroma key. Use this to select parts of windows based on their color.
2. Color: Select the color you want to select in your window
3. Similarity 1-100: Select the similarity. IE blue to sky blue, royal blue, turquoise, etc.
4. Blend: Select the sharpness of the chroma key edges.Finishing up and looking at it:

​This is a screenshot below of a sample with two images added – one with a white color, and one with a light blue in order to demonstrate transparency.

Source:Image Slideshow
​An Image slideshow is a set of pictures that change periodically. This is usually used for advertisements, although serves many different purposes.
1. Time between images (seconds): Time between changes in photos.
2. Disable fading: Check this if you want a cut to the next image rather than a fade.
3. Fade in Only: Uncheck if you want it to fade out and in.
4. Randomize: Check this if you want the next picture shown to be random.
5. Add Button: Add to select pictures
6. Remove Button: Remove images from queue
7. Move up: Change order of a picture upwards in queue
8. Move Down: Change order of a picture downwards in queue

A screenshot below demonstrates the slide show in action and the settings used.

Source: Global
Global sources are the same as any other source, except they translate across multiple scenes. This is especially useful for audiovisual devices such as cameras that only allow allow a single feed at a time and cannot be added to multiple scenessimultaneously.

1. To start using global sources, first click “Global Sources…” in the bottom right hand button menu of the main OBS window.
2. Then, click “Add” and select the appropriate source type.
3. Add source like you would normally add a source.
4. Finish editing, and then click ok.

5. Right click under the Sources header in the main OBS window, and click “Add>Global Source>Your Source” Your Source is the name of your global source you setup in steps 1-4.​

Because these look and act like normal sources, we will not be showing what this would look like.

Source: Text
Text sources are about what they sound like: text with manipulation.
1. ​Font: Font for your text
2. Color: Color of your text​
3. Opacity: Transparency/Opacity of text
4. Scroll Speed: How fast text will scroll across the screen. Higher speeds are hard to read!
5. Background color: Set a background color for the text to be on (rectangular)

  • Background opacity: Transparency/Opacity of background color

6. Use Outline: Set a outline for the text (not background box)

  • Outline color: Color of the outline around text
  • Thickness: Thickness of the outline
  • Opacity: Transparency/Opacity of outline

7. ​Font Size: Set size of the text. We recommend larger fonts downscaled as opposed to upscaled small fonts.
8. Bold/Italic/Underline General text settings
9. Vertical: Place letters vertically stacked as opposed to horizontally across screen

10. Use custom text extents: Check this if you want your long text to be constrained to a smaller source size, or if you want your small text. We recommend this only for dynamic (scrolling or dynamic files) text.

  • Size is size of extent in pixels.
  • Wrap checked is if text wraps in side extent. For example: (start of extent) testing 123 testin (end of extent)
  • Align: Align text to left/center/right. Only supported if using extent and wrapping.

​11. Use text from File: Select this to have text come from a file. Useful for chatting capture or other dynamic data.
​This is an example (and properties) of a text source.


Source: Video Capture Device
These are webcams, DV cameras, and notably most capture cards will have output in this source.

1. Device: Select device here
2. Flip Image Vertically/horizontally: Flip image either mirrored down, or sideways
3. Deinterlacing: If your source has lines or computorized disortion in it, select this and a method.

  • Methods are dependent on the video source, and vary widely.
  • Top Field/Bottom Field first: Start deinterlacing from top or bottom. We recommend top generally.Video:

4. Custom Resolution: Select only part of a camera or video source here.
5. FPS: We recommend 29.97 for most source inputs. This depends on your capture card or camera’s settings
however. Please use native framerates.
6. Use output formats: Change how the video source is output. Some cameras have additional functions if set to certain output formats.
7. Use Buffering (ms): Buffer video. Recommended not turned on unless you are having major issues and are technically inclined.

8. Chroma Key:

  • Use this to select parts of windows based on their color.
  • Color: Select the color you want to select in your window
  • Similarity: Select the similarity. IE blue to sky blue, royal blue, turquoise, etc.
  • Blend: Select the sharpness of the chroma key edges.
  • Spill Reduction: Use this if you’re getting reflections off of objects onto normally not color keyed objects such as a background tinting someone’s hair.

9. Audio:

  • Audio Input Device: Have a secondary audio feed from your video source. Generally recommended for capture cards if only if you are capturing console output. Not recommended on for video and webcams or PC output.
  • Output Audio to stream only: Set it to capture internally to stream
  • Output audio to desktop: Externally capture it to your desktop audio devices.

10. Gamma: Set this to adjust gamma. We recommend playing with this to make sure that it’s correct, as video sources sometimes need adjusting vs other sources.

This is an example of a video taken from a super old DV camera connected via i1394 and it’s settings.

Source: Game Capture
This is a source that directly captures your video output. It is very efficient when using Aero, and only captures the game itself. If you have difficulty getting your game to capture, try to use 32-bit OBS as this sometimes will solve it. Note: You should not have to do this anymore, but we recommend to test before submitting any bug reports to them.

1. Select Application: Select the game you want to capture.
2. Use/set hotkey: Use hotkey to capture to capture current game. Some settings below alter how this is done.

  • Stretch image to screen: Check if you want the game to be fullscreen on stream, but not on your own screen.
  • Ignore aspect ratio: Ignore games aspect ratio
  • Capture mouse cursor: Uncheck if you do not want a mouse cursor. Useful for games played with keyboard only.
  • Invert cursor on click: Invert the color of the cursor when you click something.

This is a screenshot of game capture in action with it’s settings:

Hopefully after reading this through, you will have a better understanding of the features that OBS offers currently. This is subject to change rapidly, as it is an open-source program developed by community members.
