Script & scenes, written
Your topic becomes a structured script, then a scene-by-scene shot plan. Nothing to storyboard by hand.
Prompt in. Finished MP4 out.
Describe a video.
Describe a video.
Get the whole thing.
Type a topic. It writes the script, builds the scenes, records a real neural voiceover, animates the captions, adds the motion — then exports the MP4 right in your browser. Vertical for Reels and TikTok, wide for YouTube. No render farm. No watermark.
How it works
Three steps, and you never touch a timeline.
There is no editor to learn and nothing to drag. You give it a brief; it hands back a finished file.
-
Step 01
Describe it
One prompt box. Say what the video is about, roughly how long it should run, which language it should speak, whether it’s 9:16 or 16:9, and which of the three visual styles you want.
-
Step 02
It builds the whole video
Script, then scenes, then a real neural voiceover, then animated captions and background motion — assembled clip by clip and chapter by chapter. If a piece drops out, it retries and keeps going without you.
-
Step 03
Export the MP4
The render runs on your own machine with WebCodecs — so there’s no queue, no render farm bill and nothing stamped across the corner. The file lands in your downloads, ready to post.
What’s inside
Everything a finished video needs, generated for you.
Not a pile of assets to assemble — the script, the voice, the visuals and the captions all come out of the same pass.
Real neural voices
Microsoft edge-tts voices in many languages — a proper narrator, not a robotic beep-track.
Animated captions
Captions are timed to the voiceover and burned into the frame, so they survive every re-upload.
Long-form, up to ~25 min
Chapter by chapter, clip by clip. Full explainers and documentaries, not just 30-second hooks.
It keeps going without you
Long builds run on their own and recover if something drops out mid-way. Close the tab, go do something else, come back and the video is further along than you left it.
Three visual styles
Real stock footage when you want it to look shot. AI-generated images when you want it to look made. 2D animation when you want a cast of characters carrying the story.
Browser-side export
WebCodecs renders the MP4 locally. Free every time, no watermark, no upload of your finished cut.
One Lumora account
The same sign-in and the same shared credit balance as the rest of your Lumora apps.
2D animation
A cast of 28 — drawn by code, not licensed.
Pick the 2D animation style and your video gets actual characters. Every one of them is generated on a canvas, frame by frame. There is no stock artwork anywhere in it, which is why they can move, react and speak instead of sitting still.
- Poses and walking. Characters stand, gesture and move across the scene as the narration goes.
- Expressions. Faces change with the beat of the script rather than holding one frozen smile.
- Automatic lip-sync. Mouths follow the neural voiceover with no manual keyframing.

Output shapes
Built for the feed, or built for the player.
Choose the shape up front and the whole video is composed for it — framing, caption placement and pacing included.
Vertical, for the scroll
Full-height framing with captions parked where thumbs aren’t. The format short-form platforms actually reward.
Instagram ReelsTikTokYouTube Shorts
Widescreen, for the long watch
Room to breathe for explainers, documentaries and tutorials — the shape that suits a twenty-five-minute build.

Sample output
Watch one it made, start to finish.
A full 70-second vertical cut. Nothing was edited afterwards — this is the file that came out of the export button.

FAQ
Questions, answered plainly.
Do I need to install anything?
No. It runs entirely in a modern web browser at app.aivideogenerator.cc. You sign in with your shared Lumora account at id.lumorabuild.com — the same login you use for the other Lumora apps.
Is there a watermark on exports?
No. Export is free and runs locally in your browser using WebCodecs, so there is no render queue, no render farm and nothing stamped on top of your video.
How long can a video be?
Up to roughly 25 minutes. Long videos are assembled clip by clip and chapter by chapter rather than in one pass.
What happens if I close the tab during a long build?
The build keeps going on its own and picks itself back up if a piece drops out. You can close the tab, come back later and carry on from where it got to.
Can I make vertical and widescreen videos?
Both. Choose 9:16 vertical for Reels, TikTok and Shorts, or 16:9 widescreen for YouTube. The framing, captions and pacing follow the shape you pick.
What do the visuals actually look like?
There are three visual styles: real stock footage, AI-generated images, or 2D animation. You pick the style and the generator builds every scene in it.
Where do the 2D characters come from?
They are drawn by code on a canvas — no stock artwork. There are 28 characters, each with poses, walking, expressions and automatic lip-sync to the voiceover.
What voices and languages are available?
Real neural voices powered by Microsoft edge-tts, available in many languages.
What does it cost?
2 credits to start a video, then 2 more credits per additional minute — so about 2 credits for a one-minute video, 10 for five minutes and 50 for twenty-five minutes. Exporting the MP4 costs nothing extra. Credits are your shared Lumora balance, managed at the account center.
