Projecting at Conferences Using OBS Streaming Software #
Generally, in conference venues with 50-100 or more participants, streaming software is used to project materials. As a projection method for such conferences, we will introduce how to project xBridge using the streaming software OBS. With projection, you can display subtitle results transparently together with presentation materials like PowerPoint, as shown in the photo below.
Screen Projection Translation Mode is also available
This guide is created using the screen projection subtitle mode described in Joining a meeting as a viewer (screen projection subtitle mode), but you can use the same operations in translation mode as well.
