PowerPoint With OBS Studio: How to Capture as a Window Source

When you present a PowerPoint slideshow in OBS Studio, capturing the full screen often shows your desktop icons, taskbar, and other open applications. This can distract viewers during a live stream or recording. The root cause is that OBS cannot directly capture a slide show window using the standard Window Capture source because PowerPoint renders slides in a separate full-screen window. This article explains how to set up PowerPoint so OBS can capture it as a clean window source, hiding all desktop clutter.

Why PowerPoint Cannot Be Captured as a Standard Window Source

PowerPoint slideshows run in a special full-screen mode called “Slide Show” mode. In this mode, PowerPoint hides its window frame and covers the entire monitor. OBS Studio’s Window Capture source works by identifying a window by its title and capturing its rendered content. Since a full-screen slide show has no standard Windows window frame, OBS cannot detect it as a selectable window. The result is that users fall back to Display Capture, which grabs everything on the screen including the taskbar and other open windows.

The fix involves changing PowerPoint’s slide show display settings. PowerPoint includes a hidden option that lets slides play inside a regular window. This window has a title bar, can be resized, and appears in OBS’s window list. Once you enable this mode, OBS can capture the slide show as a clean Window Source with no extraneous elements.

Setting Up PowerPoint Slide Show to Run in a Window

Before you open OBS, you must configure PowerPoint to display your slides in a window. This is a per-presentation setting, so you must repeat it for each file you intend to capture.

1. Open your PowerPoint presentation
   Launch PowerPoint and load the file you want to present or record.
2. Go to Slide Show > Set Up Slide Show
   Click the Slide Show tab on the ribbon. In the Set Up group, click “Set Up Slide Show”. A dialog box opens.
3. Select “Browsed by an individual (window)”
   In the Show type section, choose the option “Browsed by an individual (window)”. This tells PowerPoint to run the slideshow inside a regular window instead of full-screen.
4. Click OK
   Close the dialog box. The setting is now saved for this presentation.
5. Start the slide show
   Press F5 or click the Slide Show icon at the bottom of the PowerPoint window. The slides now appear in a resizable window with a title bar.

To verify, check the window title. It should read “PowerPoint Slide Show” followed by the presentation name. This is the window OBS will capture.

Adding a Window Capture Source in OBS Studio

With the slide show running in a window, you can now add it as a source in OBS Studio.

1. Open OBS Studio
   Launch OBS. Ensure your scene is selected in the Scenes panel.
2. Add a new Window Capture source
   In the Sources panel, click the + icon. Choose “Window Capture” from the menu. Name the source something like “PowerPoint Slides” and click OK.
3. Select the PowerPoint slide show window
   In the Properties dialog for Window Capture, open the Window dropdown list. Look for an entry that starts with “PowerPoint Slide Show”. Select it. OBS will now capture that window exclusively.
4. Adjust the capture settings
   Leave “Capture cursor” checked if you want to show your mouse pointer during the presentation. Uncheck it if you prefer a clean cursor-free feed. Click OK.
5. Resize and position the captured window
   In the OBS preview, drag the corners of the source to fill the canvas. Hold Shift while dragging to maintain the slide’s aspect ratio.

Your OBS scene now shows only the PowerPoint slide area. No desktop icons, taskbar, or other windows appear.

Managing Presenter View While Using Window Capture

If you need presenter view for notes and slide previews, you must use a dual-monitor setup. PowerPoint’s presenter view appears on a second monitor while the slideshow window stays on the primary monitor. OBS captures the primary monitor’s window.

1. Connect a second monitor
   Attach an external display to your computer. Extend your desktop, do not duplicate it.
2. Set presenter view monitor
   In PowerPoint, go to Slide Show > Monitor. Check “Use Presenter View” and select the second monitor from the dropdown.
3. Start the slide show
   Press F5. Presenter view appears on the second monitor. The slideshow window appears on the primary monitor. OBS captures the primary monitor’s window as set up earlier.

You can now read your notes on the second screen while OBS streams or records only the slides.

Common Issues When Capturing PowerPoint in OBS

OBS shows a black screen instead of the slide

This happens when Windows GPU scheduling or hardware acceleration interferes. Right-click the OBS icon and select “Run with graphics processor > Integrated Graphics” if you have a dual-GPU laptop. Alternatively, disable hardware acceleration in OBS: go to File > Settings > Advanced and uncheck “Enable hardware-accelerated video decoding”.

The captured window flickers or lags

Set the OBS Window Capture source to capture method “Windows 10 (1903 and up)” in the source properties. If the issue persists, lower the slide show resolution in PowerPoint by resizing the window smaller before starting the capture.

Window Capture list does not show the PowerPoint slide show

Ensure the slide show is running and the window is not minimized. If the window is minimized, OBS cannot detect it. Also restart OBS after starting the slide show to refresh the window list.

Presenter view appears on the wrong monitor

In PowerPoint, go to Slide Show > Monitor and select the correct display for presenter view. If the monitors are swapped, swap the selection in the dropdown.

PowerPoint Slide Show Mode vs Window Mode: Capture Differences

Item	Full-Screen Slide Show (Default)	Browsed by Individual (Window)
OBS capture method	Display Capture only	Window Capture
Desktop clutter visible	Yes, taskbar and icons appear	No, only the slide window
Presenter view support	Automatic on second monitor	Requires manual monitor assignment
Window resizing	Not possible	Drag edges to any size
Animation performance	Full GPU acceleration	Slightly reduced, typically smooth

The window mode is the only reliable way to capture a clean slide feed without additional screen masking or cropping in OBS.

You can now capture PowerPoint slides as a clean window source in OBS Studio by changing the slide show type to “Browsed by an individual (window)”. This removes desktop clutter and gives you full control over the captured area. Next, try adding a chroma key filter to the PowerPoint source for a virtual background effect. For advanced setups, use the OBS browser source with PowerPoint Online to capture slides without any window management.
