Python

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

result = fal_client.subscribe(

    arguments={
        "prompt": "Take @Image1 as the start frame. Start with a high-angle satellite view of the ancient greenhouse ruin surrounded by nature. The camera swoops down and flies inside the building, revealing the character from @Element1 standing in the sun-drenched center. The camera then seamlessly transitions into a smooth 180-degree orbit around the character, moving to the back view. As the open backpack comes into focus, the camera continues to push forward, zooming deep inside the bag to reveal the glowing stone from @Element2 nestled inside. Cinematic lighting, hopeful atmosphere, 35mm lens. Make sure to keep it as the style of @Image2."
