Queue

The Queue tab shows everything currently rendering or waiting to render.

What you can see

• Active render — the render currently being worked on, with a progress bar per step (analyzing, generating backgrounds, transcribing, rendering).
• Pending — renders queued up to run next.
• Recently completed — the last few renders, each linking to its Library card.

Each row represents a single render attempt. If you re-render the same song, a new row is created — the old render stays in the Library untouched.

Starting multiple renders

You can drop multiple MP3s into the Create tab at once. They’ll queue up and render one at a time. You can also re-render the same song multiple times (for example, after regenerating backgrounds) — each attempt becomes its own queue row and its own Library card.

Pausing or cancelling

• Pause queue — stops new renders from starting. The current one finishes.
• Cancel a specific render — removes it from the queue. If it’s already rendering, the row shows a Cancelling… label on the progress bar while the server tears down the render (the renderer and helper processes can take several seconds to stop cleanly). Once teardown finishes, the row disappears and any partial output is discarded.

If a render fails

A failed render shows the error message in the Queue. Common causes:

• Render error — see Rendering failed.
• Background fetch error — the background image service returned an error. Check your internet connection and retry; the app already retries with backoff on transient failures.
• Out of disk space — rendering needs ~500 MB of free space per song.
