AI long-form YouTube videos, chapters and all.

An AI long-form YouTube video generator writes and produces a full-length horizontal video rather than a Short. Shortmint makes videos of about nine minutes at 16:9 from a single topic, with a script split into numbered chapters, narration, pictures, drawn chapter cards and chapter timestamps in the description.

Why add long videos to a Shorts channel

Shorts bring people to a channel. Long videos are what they stay for, and they count toward watch hours in a way Shorts don't. A channel that only posts Shorts gives a new subscriber nothing longer to watch. Shortmint makes both from the same studio, with the long videos kept on their own screen and schedule so the two never get mixed up.

How a long video is built

1. An intro that says what the viewer will try or learn, and why it's worth nine minutes.
2. Numbered chapters, each one self-contained, so a viewer can skip to the part they came for.
3. Chapter cards and on-screen tests drawn pixel-exact, not generated, so a "try this now" moment shows exactly what to look at.
4. A payoff that ties the chapters together.
5. A 12-second end screen with nothing important underneath, because that's where YouTube places its subscribe and next-video buttons.

The description gets chapter timestamps, so YouTube shows the chapters on the progress bar and in search.

Built to survive a long render

A nine-minute video has many more scenes than a Short. Every scene is saved as it's made, so if a run is interrupted, by a closed laptop or a failed picture, the next run carries on from the last finished scene instead of starting over.

Its own schedule

Long videos run on a separate daily schedule from Shorts, with their own topic list. Each one is uploaded with its own title, description, tags and thumbnail. Like Shorts, they can go up private so you can watch them first.

Shorts and long videos together

A useful pairing: make a Short about one test from a long video, and set the long video as the Short's related video so a viewer who liked the Short can tap through to the full one.
