The preview video in the bottom-right corner of the canvas shows the selected output element’s video in real time. To choose a different output element, use the dropdown menu above the preview window.

The preview video is lower quality and low bitrate, so it doesn’t reflect the final output quality. Preview mode is free of charge, and the configuration automatically switches to RUNNING mode when you either stream to your inputs or set one of the outputs live. Read about other Streamrun modes.

Why the preview video might not be available

At times, we may shut down preview servers to prioritize resources for live streams. When you reload the Streamrun editor, a new attempt to grab a preview server is made.

Each user can have one active preview at a time. If you're editing multiple configurations in different browser tabs, the preview will remain active only in the most recently opened tab. Additionally, the preview will automatically close if your browser is inactive for a while. Reloading the editor will restart the preview in this case as well.
