The render queue

Video renders run in the background; the top-bar queue follows them for you and your teammates, and nothing is lost if you navigate away.

A video render takes one to several minutes depending on the engine and the length. The moment you click Generate it is queued, and the queue icon in the top bar shows a count and a spinner. Open it to see every render of the last 24 hours in the workspace — including the ones your teammates started — with Open clip and Library links once a render lands.

You can leave the page, switch tools or close the tab: the render continues and the queue picks it back up.
A render that fails, or that is still "processing" past the engine's deadline, is marked failed and refunded automatically.
Finished clips are in your Library with their recipe; the queue is a view, not the only copy.
