Hey there!
Looking for a way to place a video on a Miro board?
You can upload the video to a video-sharing platform (YouTube, Vimeo, etc.) and simply paste the video link on a board using the shortcuts Ctrl/Cmd+C/Ctrl/Cmd+V. The media will be displayed right on the board!
Please keep in mind that the visual preview is only shown if the source service settings allow it: private videos are not displayed on Miro boards but you can go to the video source.
