Long Form AI Video Generator
Give Rewatch an idea and it turns it into a narrated story of 3, 5, 8 or 10 minutes. The AI writes it in chapters of about one minute, illustrates every passage, has a voiceover narrator tell the whole thing and adds light animation to the images. The chapters are assembled into one single vertical 9:16 video, with music from start to finish and a cover image. No face on camera: the voice tells the story, the pictures follow.

Big history stories

A gentle 10 minute tale, a calm voice, soothing pictures and music that keeps playing between chapters.

How to make a long AI video
- 01
Type your idea and pick a length
One sentence is enough: a subject, a character, an era. Pick 3, 5, 8 or 10 minutes, and turn on captions if you want them.
- 02
Review the story before any image
The AI writes the script in chapters of about one minute. You read it and approve it before the first image is generated.
- 03
Let Rewatch produce the chapters
Images, voiceover, animation, editing: each chapter goes through the same steps as a short story video, then everything is assembled.
- 04
Get one single video
You get one continuous vertical 9:16 video with its music and cover image, ready for a long TikTok or a story on Facebook.
What this long form AI video generator does
From 3 to 10 minutes
Pick 3, 5, 8 or 10 minutes. The story is written for that length, split into chapters of about one minute each.
A narrated, faceless story
A voiceover narrator tells the story, images illustrate each passage and move with light animation. Nobody appears on camera.
Story approved before the first image
You read the script and approve it before production starts: no image is generated for a story you are not happy with.
One video, one soundtrack
The chapters are assembled into a single video, with music running across the whole length and one cover image.
Optional captions
Turn them on for people watching with the sound off, or leave them out to keep the picture clean. Your call.
Included in the Studio plan
Long videos are available from the Studio plan up, and in the Agency plan.

What is a long form AI video?
A long form AI video is a narrated story several minutes long, produced from an idea: a voiceover tells it, generated images illustrate each passage. On TikTok and Facebook, vertical stories are also watched in long versions: history, mysteries, bedtime stories, horror. These are subjects that need time to set a mood and hold attention to the end.
With Rewatch, you pick a length from 3 to 10 minutes. The AI writes the story in chapters of about one minute, you approve it, then each chapter is produced (images, voice, animation, editing) and everything is assembled into one single video, with the music and the cover. The format stays vertical 9:16: it is made for phones, not for a horizontal YouTube video.
