Real 9:16 Short rendered by the same pipeline.
No source footage required
One prompt in. A finished YouTube Short out.
Most YouTube Shorts tools clip up a long video you already filmed; if you have nothing to repurpose, you can't use them. MakeAIVideo writes the Short from a one-line prompt, with voice, scenes, captions, and music built into the same pipeline, then renders a 9:16 MP4 in about 90 seconds. No source footage, no timeline editing, no second tool.
Prompt to 9:16 Short
One line in, a complete vertical Short out, sized for the Shorts shelf, Reels, and TikTok.
Voiceover plus captions
A natural AI narrator reads the script, with word-by-word captions timed to the voice and baked into the export.
Auto-matched music
Background music ducks under the narration so the voice stays clear without any audio mixing.
How it works
From prompt to vertical Short in four steps
- 01
Pick your topic and aspect ratio
Type a one-line topic and choose 9:16 vertical for the Shorts shelf, Reels, and TikTok. The pipeline reads the line and immediately starts working; specific prompts get specific Shorts, vague prompts get safe defaults. Set the ratio up front, because captions auto-fit the safe area for the format you pick.
- 02
AI writes the Short script
Your line becomes a paced short-form script with a hook in the first three seconds, a body that holds attention, and a close that lands. Re-roll the script if you want a different angle, or open the editor later to rewrite a single line. The narration matches the words exactly, never a summary.
- 03
AI builds scenes, voice, captions, music
Every line of the script becomes a scene in the visual style you chose, with a natural AI narrator reading the words and word-by-word captions timed to the audio. Background music auto-ducks under the voice. Everything happens in one pass, no second tool, no manual sync.
- 04
Render and post
Most Shorts render in about 90 seconds end to end. A watermark-free 1080p MP4 lands in your library; download it for the Shorts uploader, or open the editor to swap a scene, restyle the captions, or re-roll the voice before posting.
Generate a Short, right in your browser
Set the prompt, set 9:16, hit generate. The vertical Short lands in your library, watermark-free.
All included
Everything you get in a Short render
Voice, captions, music, and 1080p export bundled into every Short.
Native 9:16
Built vertical from the prompt, not letterboxed or cropped from a wide source.
14 visual styles
Cinematic, anime, claymation, and more, applied across every scene.
Word-by-word captions
Eight caption presets, timed to the voiceover and burned into the export.
Studio AI voices
A curated library of natural narrators to match your tone.
Ducked background music
Auto-matched tracks that sit under the narration without burying the voice.
Watermark-free 1080p
Clean exports ready to post directly to the Shorts shelf.
What you can ship
A finished faceless Short per prompt, ready for the Shorts shelf.
Faceless explainers
Build a faceless YouTube Shorts channel without filming yourself. One prompt becomes a fully voiced, captioned, paced Short you can publish the same day.
List Shorts
Top-5s, common mistakes, surprising facts. The hook-body-close structure is already there; you bring the topic and the angle.
Story Shorts
Walk through a story or case study in 30 to 90 seconds with narration timed to scenes that illustrate each beat. Useful for history, science, and explainer formats.
Product Shorts
Frame a feature, a launch, or a use case in one line. The pipeline writes the read, builds the visuals, and outputs a 9:16 clip you can drop into the Shorts shelf or a launch thread.
Educational Shorts
Explain a single concept per Short with narration timed to scenes that illustrate the point. Each beat gets its own visual; nothing drags into the next.
Daily faceless posts
Run a consistent posting cadence without source footage. One prompt per day, one finished Short, no filming, no editing, no clip-mining.
If you want to clip up an existing long video you already filmed, a repurposing tool fits the job better. This is for Shorts built from scratch.
Best practices
Tips for Shorts that survive the scroll
- Front-load the hook
- The first three seconds decide whether a Short survives the scroll. Write your prompt around the most interesting line of the Short, not a generic opener like 'today we're going to talk about'.
- Pick 9:16 before generating
- 9:16 vertical is what the YouTube Shorts shelf serves; captions auto-fit the vertical safe area. Switching aspect ratios after generating costs another render, so set it up front.
- Aim for 30 to 60 seconds
- Shorts up to 60 seconds get the strongest distribution on the Shorts shelf. Beyond that, retention drops and the algorithm pushes the clip out of the short-form feed.
- Write specific prompts
- 'A 45-second faceless explainer about why honey crystallises, casual tone' will outperform 'a video about honey'. Specific topic, specific length, specific angle.
- Re-roll one scene, not the whole Short
- If a single scene misses, open the editor and regenerate just that scene. Faster and cheaper than re-rendering the entire Short.
- Match captions to the platform
- Bold, single-word captions pop on the Shorts shelf and Reels; quieter, two-line captions read better embedded in a longer post. The editor ships eight presets, pick once and reuse.

Frequently asked questions
What is an AI shorts generator?
An AI shorts generator turns a written idea or script into a finished short-form video. MakeAIVideo runs the whole pipeline from a one-line prompt: script, AI voiceover, AI scenes, word-by-word captions, and music, then renders a 9:16 vertical MP4 ready for YouTube Shorts, Reels, and TikTok.
How does the AI YouTube Shorts generator work?
You type a one-line prompt, pick 9:16 vertical, and choose a visual style. The pipeline drafts a hook-paced Short script, picks a natural AI narrator, builds a scene per beat, times captions to the voice, layers ducked music, and renders the finished MP4. A typical Short is ready in about 90 seconds.
How long does it take to generate a Short?
Most 30 to 60 second Shorts render in about 90 seconds end to end. Longer Shorts, higher-fidelity styles, and re-rolls add to that, but the typical Shorts-shelf length is ready while you make a coffee.
What aspect ratios can I export?
9:16 vertical for the YouTube Shorts shelf, Reels, and TikTok, 1:1 square for feed posts, and 16:9 landscape for the main YouTube page. Captions auto-adjust to the safe area for each format; pick the ratio before generating.
How much does it cost?
Plans start at $29/month with a 7-day free trial on every plan and $0 due today. Cancel any time during the trial for no charge. The price covers the whole Shorts pipeline, no separate add-ons for voiceover, captions, or music. See pricing.
Is there a watermark on the Short?
No. Every Short exported on a paid plan is a clean 1080p MP4, watermark-free and yours to post anywhere. Watermark removal is not gated behind a higher tier.
Can I monetize the Shorts on YouTube?
Yes. Shorts generated on a paid plan are yours to monetize on YouTube, TikTok, Reels, and any other platform. The AI scenes are generated, not sourced from a stock library, so there's no third-party licensing question. See the full terms.
Can I edit the Short after it generates?
Yes. Every render opens in the built-in editor where you can rewrite captions word by word, restyle the caption preset, swap the voice, re-roll a single scene, or trim the clip. The default output is built to post as-is, editing is optional.
Do I need source footage like other Shorts tools?
No. Most YouTube Shorts generators clip up a long video you already have; if you have no source footage, you can't use them. MakeAIVideo writes the Short from a one-line prompt, so you can post without filming or repurposing anything. If you already have a written script, Script to video narrates your exact words instead.
How is this different from a clip-from-long-video Shorts tool?
Repurposers cut your existing long videos into shorter slices; MakeAIVideo generates the Short from scratch. That means you can run a faceless Shorts channel without ever filming a long video, podcast, or livestream first. Both approaches have their place; pick the right tool for what you've already shot.
What happens after my 7-day trial?
Your plan starts billing at its monthly rate at the end of the trial. Cancel any time during the trial for no charge and you won't be billed.
