AI scenes with camera moves, narration, captions and music
A what if video takes an impossible or unlikely scenario and explains what would actually happen, step by step. imageat's What If preset writes the script around real science, illustrates it in a clean 3D explainer style with suspense music, and ends by asking viewers a question. It is one of the 18 presets in the AI Story format.
One prompt. One finished video.
Every clip below is the first result for the prompt under it, straight out of the studio. Tap one to hear it.
Built for Hypotheticals
Start Now!Escalating structure
The script moves from the first minute to the long-term outcome, so each scene raises the stakes.
3D explainer look
Scenes default to a clean stylized 3D render with soft lighting, the style viewers know from science channels.
Science-first writing
The What If preset asks the writer for real physics, biology and astronomy rather than pure fantasy.
Question ending
The video ends by asking viewers what they think would happen next, which invites comments.
Suspense score
A suspense music bed plays under the narration by default. Switch to Epic for big cosmic topics.
Direction line
Add a note like "focus on the first 24 hours" or "compare with Mars" to steer the angle.
How it works
Ask the question
Type the scenario, such as what if the oceans froze overnight.
Pick the length
Choose 30, 60 or 90 seconds and a narrator voice. The What If preset is already selected.
Render the explainer
The MP4 renders in your browser with scenes, captions and music, then lands in your history.

Keep it physical
Scenarios with a measurable change, like gravity doubling, give the script concrete steps to explain.
Use 60 seconds for chains
Topics with many knock-on effects need around 18 scenes to breathe, so pick 60 or 90 seconds.
Check the numbers
AI can get figures wrong. Verify distances, temperatures and dates before you post.
