Previous release notes:

  • Added the ability to capture Vulkan-based games with game capture. Big thanks to Ubisoft Montreal for submitting this feature! [Littlematth/jpark37/Jim]
  • Added a new capture method to window capture which allows capturing browsers, browser-based windows, and Microsoft Store (UWP) programs [jpark37]
    • By default, it will use "Automatic", which will use the normal method on most windows, and the new method on browsers, browser-based windows, and Microsoft Store (UWP) programs
    • The downside of the new method is that it can cause a bit of cursor lag, as well as a highlighted border around the captured window. The border itself does not get captured, however.
    • You can choose which capture method to use in window capture properties
  • Added advanced scene collection importing (on the menu bar, Scene Collection -> Import) which allows you to import from other common streaming programs [Dillon]
  • Added Media source hotkeys to allow control of playback (stop/pause/play/restart) [cg2121]
    • For now, these are just hotkeys. User interface for this is also planned for future updates
  • Added the ability to drag and drop URLs to create browser sources (after displaying a confirmation prompt to ensure it was by intention) [WizardCM]
    • Developers can add an embed to their web pages that let them pre-specify parameters that automatically get set in the source when it's dragged into OBS. See this link for more details: https://obsproject.com/tools/browser-drag-and-drop

    • Note that this will not work while using a Stinger transition or the "Cut" transition
