Can I make it with just one photo?

Yes. One clear selfie is enough — half-body or full-body works best, with your face visible. You do not need a city photo: the tool builds a believable downtown, riverside or night skyline around you automatically.

Do I need to shoot a city background?

No. The city background is optional. Upload one only if you want the giant to appear in a specific place — your own street or skyline photo. Otherwise skip it and the AI generates the city for you.

Why does my city giant look fake?

Fake-looking giants almost always fail in three places: feet floating above the street, the camera angle on the person fighting the angle on the buildings, or light hitting the giant from the wrong side. This effect fixes all three — feet planted with shadows and dust, one unified low-angle view, and light matched to the buildings.

Can CapCut templates do this?

Template apps can do a quick version, but you have to hunt for materials and tune settings yourself, and the face often drifts. Here you upload one photo, pick one of four giant styles, and get a 5–12 second vertical video in one shot — no editing timeline.

How can I tell an AI composite?

Look at the feet and the windows: AI composites often miss contact shadows, and building grids warp near the giant. Real footage has consistent grain, motion blur and reflections. When in doubt, ask for the original clip — and always label your own giant videos as AI-made when you post.

Beginner steps for a city giant?

Three steps: 1) upload one selfie with a clear face, 2) pick a style like Striding Between Towers and hit generate, 3) download the vertical video and post it. First-timers should start with the daytime stride — it is the most forgiving style.

Must I label it as AI-made?

Yes — always label it as AI-generated when you post, and never present it as real news. Use your own photo or one you have permission to use. The effect is built to be playful, never destructive: no stomping crowds or crushing buildings.
