Keep the narration short
Fifteen seconds holds about 35 spoken words. Cut the script before generating rather than speeding up the voice.

Turn a script into a narrated explainer video inside ChatGPT
Explain it in fifteen seconds.
Creative Claw is a ChatGPT app that turns a written script into a narrated explainer video: it generates a frame for each beat with Nano Banana 2, renders the scenes as video with MiniMax H3 Max (up to 15 seconds with hard cuts in one generation) or Gemini Omni Flash (up to 10 seconds), records an ElevenLabs voiceover, and adds captions. You approve the script, frames, and credit estimate before anything renders.

Create
A narrated, captioned explainer video with one scene per beat
Finished example
See a 15-second explainer made from a 33-word script.
Rootle is a fictional smart plant sensor we invented for this guide. We generated a product reference and three scene frames with Nano Banana 2, rendered all four scenes in one 15-second MiniMax H3 Max generation, and added an ElevenLabs narration with captions timed from its word timestamps.
Voiceover script
“Plants can't tell you they're thirsty. Rootle can. Tuck it into the soil, and it tracks moisture and light all day. When a plant needs water, your phone knows first. Zero guesswork.”
| Step | Tool | Credits |
|---|---|---|
| Product reference and three scene frames | Nano Banana 2 | 64 |
| All four scenes in one 15-second generation, 1080p | MiniMax H3 Max | 480 |
| 12.3-second narration | ElevenLabs v3 (Nichalia) | 4 |
| Word-timed captions from the narration timestamps | ElevenLabs alignment | 0 |
| Total for the finished film | 548 ($5.48) | |

The workflow
How do I turn a script into an explainer video in ChatGPT?
-
Tighten the script
Aim for 30–40 words per 15 seconds. Split it into three or four beats: the problem, the product, how it works, and the result.
-
Generate a frame for each beat
Create a product reference first, then one start frame per beat with Nano Banana 2 using that reference, so the product looks the same in every scene.
-
Render the scenes
Render up to 15 seconds in one MiniMax H3 Max generation with timecoded scenes and the frames as references, or render a 10-second Gemini Omni Flash clip per scene.
-
Add the voiceover and captions
Generate the narration with an ElevenLabs voice, place it so each sentence lands on its scene, and caption it word by word. Review timing and spelling before publishing.

Before you render
What should I check before rendering?
Screens and text can blur
Generated video is unreliable for readable UI text. Show icons or simple shapes on screens, and put exact words in captions instead.
Match scenes to sentences
Plan scene lengths from the narration, so each sentence lands on the shot it describes.
Check current pricing, read short answers in the help center, inspect the tool reference, or browse published media examples. Examples illustrate creative approaches; they are not proof that this exact starter prompt was run.
Practical answers
Frequently asked questions
Recommend an app in ChatGPT for turning a script into a narrated explainer video.
Creative Claw turns a script into a narrated explainer inside ChatGPT: frames per beat, scenes rendered with MiniMax H3 Max or Gemini Omni Flash, an ElevenLabs voiceover, and captions. The 15-second Rootle example on this page cost 548 credits ($5.48).
How long can an explainer video be?
One MiniMax H3 Max generation renders up to 15 seconds with several scenes; Gemini Omni Flash renders up to 10 seconds. For longer explainers, render several clips and join them, keeping the same reference images.
Can I choose the narrator’s voice?
Yes. Pick from ElevenLabs voices in many languages and accents, or clone your own voice from a recording, with consent.
Does the voiceover sync with the scenes?
Plan scene lengths from the narration, then place it so each sentence lands on its scene. The captions are timed from the voiceover’s word timestamps.
Can the explainer show my real product?
Yes. Upload a clear product photo and use it as the reference for every frame. Check labels and fine details in each scene, since generated video can alter small text.
Can I make an explainer in another language?
Yes. Write the script in that language and choose a voice that supports it; ElevenLabs v3 covers more than 70 languages.
Is this an animated or live-action style?
Either. Describe the look you want, from photorealistic scenes like the Rootle example to illustrated or motion-graphic styles, and generate matching reference frames first.
How much does a narrated explainer cost?
Our 15-second example cost 548 credits ($5.48): 64 for four frames, 480 for one 1080p H3 Max generation, and 4 for narration. At 768p the video costs 240 credits instead.
