## Overview
Output videos include an audio track; there is no option to turn it off.
## Query Task Status
After submitting a task, use the unified query endpoint to check
progress and retrieve results:
Learn how to query task status and retrieve generation results
::: tip[]
For production use, we recommend using the `callBackUrl` parameter to
receive automatic notifications when generation completes, rather than
polling the status endpoint.

Real-time playback. Wide shot of a ruined city:
collapsed towers, fires blazing, storm clouds with
lightning. Camera drops fast from the sky over burning
streets and tilted buildings. Smoke and dust fill the
air. A lone hero walks out of the ruins, silhouetted
by fire. Camera shifts front: his face is dirty with
dust and sweat, eyes firm, a faint smile. Wind blows,
debris rises. Extreme close-up: his eyes reflect the
approaching enemy. Music and drums hit. Final wide
shot: fire forms a blazing halo behind him — reborn in
flames with epic cinematic vibe.
