AI YouTube Shorts
Generator. One idea, start to payoff.
Describe the shot and generate vertical footage for a Short — up to 30 seconds in one take, with sound, built around one complete idea rather than a clip that just stops.
Every clip on this page was generated on imageat from the prompt shown with it
The whole idea in one clip
The newest models hold a scene for up to 30 seconds, so a Short no longer has to be stitched from four-second fragments. Describe where the shot starts, what changes and where it lands — this one was a single Wan 3.0 run, drip and room tone included.
Prompt: Vertical explainer shot. A single drop of dark blue ink falls into a tall glass of still water, blooms into slow curling clouds, then the clouds settle into a calm layered gradient by the end. Macro lens, backlit against black, the camera slowly pushes in as the ink spreads. Soft drip sound, a quiet low hum. No text, no watermark.
Pick the model for the Short
Every model below generates natively at 9:16. The generator only offers the lengths and resolutions the chosen model supports, and the studio shows the credit cost before anything runs.

Opening, development, payoff
The smallest structure that still feels finished. Keep the subject and the look the same across the three beats — or write all three into one 30-second prompt — and the clips cut together.
Opening
Why should I keep watching?
Establish the subject and the question in one shot. A Short has no title card — the first frame is the premise.
A single seed resting on dark wet soil, lit from above
Generate this beatDevelopment
What is actually happening?
Show the change. This is what people came for, so give it the most time and the clearest framing.
The seed splitting and a pale root pushing down into the soil in time lapse
Generate this beatPayoff
Was that worth it?
Land on a resolved image. A Short that stops mid-action feels broken; one that arrives somewhere gets rewatched.
The seedling fully open with two leaves catching the light, camera settling

Start Now!Explainer b-roll
Illustrative footage to cut a voiceover over, instead of stock clips.
Educational channels
Show a process clearly when filming it would be slow or impossible.
Product demos
A short clear look at a product doing the one thing it is for.
Faceless channels
Presenter-free footage for channels that never show a face.
Repurposing long-form
Vertical visuals to rebuild a long video as a Short.
Opening shots
A strong first frame to lead a Short that continues with your own footage.
A Shorts prompt
formula
Subject and action, then the camera, then the light, then the sound. Say what resolves by the end — a Short that arrives somewhere gets rewatched.
Science explainer
8s · 9:16Frost crystals forming and spreading across a window pane in extreme macro, cold blue morning light, an orderly demonstrative shot with the subject isolated and easy to follow, clean even lighting, vertical 9:16 framing, no text overlays, no watermark
Mini documentary
10s · 9:16Molten glass being turned and shaped on a blowpipe, orange glow against a dark workshop, observational documentary camera with natural available light, patient framing, no face in frame, vertical 9:16 framing, no text overlays, no watermark
Product demo
6s · 9:16A hand pressing the lid of a stainless steel flask until it seals, close framing with crisp surface detail, controlled lighting on a plain surface, the action readable at a glance, vertical 9:16 framing, no text overlays, no logos, no watermark
Story opening
8s · 9:16A camera pushing slowly through morning fog toward a single bare tree on a hill, framing that implies something before and after this moment, cinematic depth of field and filmic grading, vertical 9:16 framing, no text overlays, no watermark
Made with imageat
Every prompt is below its clip. Open one in the studio with the model, length and quality preloaded.
From an idea to footage you can cut
Describe the shot
Say what happens and how the camera behaves. A Short works best when one clip carries one idea that a viewer understands without a caption.
Choose the type, look and length
Pick a content type, a visual direction and a model — Wan 3.0, Kling 4.0, Seedance 2.5 or FLUX 3 Max — then a length up to 30 seconds. Vertical 9:16 is applied for you.
Generate, then assemble the Short
The brief opens in the imageat video studio with everything preloaded. Download the clip and edit it with your voiceover, captions and any other footage.

Make the idea land
Describe an opening, a change and a resolution, then generate it as one take or as beats with the same look so they cut together.
