Long-form AI video generator
A long-form AI video generator: one idea in, a finished 10, 30 or 60+ minute video out.
NimbleVid writes the script, records the narration, generates every visual from scratch, keeps your characters consistent from the first scene to the last, adds motion, makes the thumbnail and the description, and assembles the final cut. No stock footage. No manual editing. Long-form means 10, 30 or 60+ minutes, not 30 seconds.

Complete, unedited renders. For each one, NimbleVid wrote the script, recorded the narration, generated every scene image, added motion and assembled the final cut: the whole runtime, exactly as exported.

Runtime
How long can a NimbleVid video be?
As long as the script. The word cap is the only length limit, and it's a plan setting, not a product one.
4,000-word scripts on Basic
About 24 minutes of narration per video. Every plan starts long-form. There is no short-clip tier to grow out of.
10,000 words on Pro
Roughly 60 minutes: an hour-long documentary from a single script, narrated in one voice.
20,000 words on Creator
About 120 minutes of narration. The cap is the script; every step after it runs at whatever length the script is.
Over 60 minutes long
NimbleVid can make videos over 60 minutes long: one continuous narration, hundreds of generated scenes, one upload-ready MP4.
The free credits new accounts in select regions get (good for 7 days) cover a real first video: enough to judge the output, not enough for a 20-minute upload. Long-form is what the paid plans are sized for.
Built for length
What breaks at 20 minutes, and how NimbleVid is built for it
A long video isn't a short one that runs longer. Four things go wrong at length in most tools; each one has a specific answer here.
Scene 230 has to look like scene 3
Every visual style carries a set of reference images that ride along on every render, so the look holds across the whole runtime. A continuity pass reads the full script for recurring characters and carries each one's description into every scene they appear in: the same face, the same clothes, from the first minute to the last.
240 scenes, each on its own beat
The script is split into scenes against the voiceover's actual timestamps, so each image changes on the line it illustrates: a fresh scene roughly every five seconds, for the whole video. Long-form pacing is a timing problem, and the timing comes from the narration itself.
One narration, one voice
The voiceover is generated as one continuous ElevenLabs performance in the voice you chose (Standard for volume, Studio for the richest sound, or a clone of your own), so minute 25 sounds exactly like minute 1.
Costs that scale with length, not against it
Every generation is priced by its length, and final assembly is a flat fee at any runtime: there's no per-minute export charge and no long-form surcharge. Every button shows its cost before you click, and failed jobs are never charged.
The pipeline
Everything a long-form upload needs, from one idea
Nine steps, each done for you. You review; the pipeline runs in the background.
Style
Paste 1 to 4 videos from any YouTube channel and NimbleVid clones its writing voice and its visual look, or build a style of your own.
Title
Click-optimized titles tuned to your niche and the style you picked.
Script
A full script at the length you choose, with a research pass before writing and a verification pass after. Edit anything before it's narrated.
Voiceover
ElevenLabs narration in one of 30 voices: Standard for volume, Studio for the richest sound, or a clone of your own voice.
Scenes & images
The script is split into scenes timed to the narration, and every scene gets its own generated image in your style.
Motion
Ken Burns motion on every plan; generative animation on paid plans for the scenes that need real movement.
Assembly
A finished MP4 in 16:9 or 9:16, with subtitles and intro/outro branding on tap.
Thumbnail
Two thumbnail options in your channel's style, editable in place.
Upload kit
A description with real timestamps, tags and a pinned comment: everything YouTube asks for at upload.
Cost
What a long-form video costs
Credits, by runtime. Every generation is priced by its length, so a 20-minute video costs about twice what a 10-minute one does: there's no long-form surcharge and no per-minute export fee.
| Video length | Scenes | Script | Credits |
|---|---|---|---|
| 5 minutes | ≈ 60 | ≈ 835 words | ≈ 670 |
| 10 minutes | ≈ 120 | ≈ 1,670 words | ≈ 1,240 |
| 15 minutes | ≈ 180 | ≈ 2,505 words | ≈ 1,810 |
| 20 minutes | ≈ 240 | ≈ 3,340 words | ≈ 2,380 |
| 30 minutes | ≈ 360 | ≈ 5,010 words · Pro plan | ≈ 3,523 |
| 60 minutes | ≈ 720 | ≈ 10,020 words · Creator plan | ≈ 6,966 |
Same model as the pricing calculator: a fresh scene image roughly every five seconds at default quality, a Studio-quality voiceover, two thumbnail options, no animation. Ken Burns motion adds one credit per scene; generative animation is priced per second of clip. Scripts over 4,000 words need Pro or Creator. Every button in the workspace shows its exact cost before you click, and failed jobs are never charged.
