Time-Lapse City generates a city-focused time-lapse video from your text prompt. You get a fast-moving urban scene, so the city description should focus on skyline, streets, weather, and time of day.

When you enter a city_description (text: Describe the city scene), Time-Lapse City interprets that prompt as a moving urban setup rather than a static postcard.
The model maps your text into a city layout, camera framing, lighting conditions, and motion cues, then compresses activity over time into a single accelerated video.
It looks for details like roads, towers, waterfronts, weather, transit, and pedestrian density to decide what should visibly change frame to frame.
If your description suggests a recognizable location, it leans into familiar visual patterns associated with that place.
It also makes stylistic decisions about pacing, cloud drift, traffic streaks, window lights, and street energy so the final clip reads clearly as a city time-lapse instead of a normal establishing shot.

Include the city and what makes the scene look active. Traffic, weather, skyline type, and time of day all help the time-lapse effect feel more believable.
Usually, yes. Well-known cities have stronger visual associations, which helps the model create a more recognizable urban time-lapse.
Yes, but be specific. Instead of just saying "cinematic," use details like "foggy downtown at blue hour" or "rain-soaked neon streets at night."
Both can work, but they create different results. Wide views usually produce cleaner, more readable time-lapse motion across clouds, lights, and traffic patterns. Street-level prompts feel busier and more energetic, which is useful for nightlife, shopping districts, and event content.
Yes. This effect is especially useful as establishing b-roll behind titles, captions, or narration. If that's your goal, describe a scene with a clear focal area and avoid overloading the prompt with too many competing landmarks, so your overlays stay readable.
