    if isinstance(update, fal_client.InProgress):
        for log in update.logs:
           print(log["message"])

result = fal_client.subscribe(
    "fal-ai/bytedance/seedance/v1/pro/text-to-video",
    arguments={
        "prompt": "A bright blue race car speeds along a snowy racetrack. [Low-angle shot] Captures several cars speeding along the racetrack through a harsh snowstorm. [Overhead shot] The camera gradually pulls upward, revealing the full race scene illuminated by storm lights"
    },
    with_logs=True,
    on_queue_update=on_queue_update,
)
