Vertical video with a payoff

Footage that carries one idea
Each clip came from the prompt shown with it. Press play, then open one in the studio with everything preloaded.
8s · Seedance 2.0First Growth
Educational
One idea, shown completely, with room for a voiceover.
Show the promptHide the prompt
A single seed sprouting and unfurling into a green seedling in time lapse, dark soil, soft top light, an orderly demonstrative shot with the subject isolated and easy to follow, clean neutral background with even lighting, vertical 9:16 framing, no text overlays, no watermark
6s · Seedance 2.0Ink Bloom
Cinematic moment
A shot that holds attention without anything being said.
Show the promptHide the prompt
Black and blue ink dropping into clear water and blooming into slow clouds, backlit against a black background, a single beautifully composed shot that holds attention on its own, cinematic depth of field with filmic colour grading, vertical 9:16 framing, no text overlays, no watermark
8s · Seedance 2.0Fine Work
Mini documentary
An observational moment that implies a whole craft.
Show the promptHide the prompt
A watchmaker's hands placing a tiny brass gear into a movement under a loupe, warm focused task light, an observational documentary moment in a real setting, unstaged and patient, no person's face in frame, vertical 9:16 framing, no text overlays, no watermark
Clips play muted and only when you press play.
Three beats
A Short is a whole idea, not a clip
The Shorts that get rewatched arrive somewhere. Plan the opening, the development and the payoff as three shots of the same subject, then generate each one with the same look so they cut together cleanly.
- 01
Opening
“Why should I keep watching?”
Establish the subject and the question in one shot. A Short has no title card and no intro — the first frame is the premise.
A single seed resting on dark wet soil, lit from above
- 02
Development
“What is actually happening?”
Show the change. This is the part 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
- 03
Payoff
“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
Keep the look description identical across all three and change only the subject. That is what makes three separately generated clips feel like one continuous Short when you cut them together.
Where it helps
Explainers, demos and faceless channels
Educators, product teams and channels that never show a face use the same studio for b-roll and opening shots.
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.
Prompt guide
A Shorts prompt formula
Subject and action, then the camera behaviour, then the light. Say what resolves by the end — a Short that arrives somewhere gets rewatched.
Science explainer
8sFrost 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
10sMolten 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
6sA 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
8sA 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
How it works
From an idea to footage you can cut
- 01
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.
- 02
Choose the type, look and length
Pick a content type and a visual direction, then a duration and resolution the selected model supports. Vertical 9:16 is applied for you.
- 03
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.
FAQ
Questions about AI YouTube Shorts
What is an AI YouTube Shorts generator?
It turns a written description into a short vertical clip. You describe the shot, choose a content type, a visual direction and a length, and the clip is generated at 9:16 — the shape Shorts plays full screen.
Can it upload the Short to YouTube?
No. imageat generates and stores video; it has no connection to your YouTube channel and cannot upload, schedule or publish. You download the clip and upload it yourself.
Will using AI video affect monetisation?
That is YouTube's decision, not something this tool can promise either way. YouTube has its own policies on disclosure and on repetitive or inauthentic content, and they change. Check the current rules for your channel and disclose AI-generated content where YouTube asks you to.
Does this guarantee views?
No, and treat any tool that says otherwise with suspicion. What it changes is how cheaply you can try an idea — you can produce several openings for the same Short instead of committing a filming day to one.
Is the output cleared for copyright?
No automatic clearance is provided. Under the imageat terms of service you own the images and video you generate, but AI output is not checked for trademarks, likenesses or third-party material, and any music you add is your responsibility. Review the terms of service for your case.
How long can a clip be?
It depends on the model — Seedance 2.0 covers 4 to 15 seconds, Seedance 2.5 reaches 30, Veo covers 4 to 8 at higher fidelity. Only supported durations are offered. A full Short is usually several clips edited together.
What does it cost?
Video generation spends credits based on the model, duration and resolution you choose. The studio shows the cost before you run it, and a failed generation is refunded automatically.
How is this different from the TikTok and Reels pages?
All three open the same studio at 9:16. This page is built around a complete idea — an opening, a development and a payoff — with presenter-free and documentary directions. TikTok is built around hooks, and Reels around polished brand and product storytelling.
imageat generates and stores video. It does not upload to YouTube, and it cannot affect monetisation, reach or copyright clearance — those are YouTube’s policies and your own responsibility. Rights and permitted use are governed by the imageat terms of service.
