What is an OVERLAY file? An OVERLAY file is an overlay collection used by Streamlabs Desktop (formerly Streamlabs OBS), a program used to capture and stream video game gameplay and other content. It is used to add one or more scenes to Streamlabs Desktop. Users can export and import OVERLAY files from Streamlabs Desktop's Settings → Scene Collections menu.

More Information Streamers use Streamlabs Desktop to record content and stream it to Twitch , YouTube, and other platforms. As part of setting up Streamlabs Desktop, streamers create one or more scenes. These scenes contain the elements a streamer wants to stream. For example, a scene may include a game window, a window that shows the streamer's face via their webcam, and the streamer's logo (saved as a .PNG or other image file). When the streamer begins streaming, all these elements are combined into one streaming video. If a streamer wants to export the graphical elements of their scenes (often referred to as overlays) as a single package, they can do so by: Opening Streamlabs Desktop's Settings → Scene Collection menu. Selecting Export Overlay File . This exports the graphical elements (and notably, not the video capture sources) of a streamer's current scenes as an OVERLAY file. Streamers can share OVERLAY files with others to allow them to import the overlays they contain.
