KitCutHow KitCut made an 8-minute film from one brief
Most AI video stops at a clip. This is a whole film: eight minutes, eight chapters, about 1,200 words of narration, painted pictures and a court drawn to scale. KitCut made it from one brief.
It is episode 2 of Padel Tactics, a YouTube channel for club padel players: Bandeja, Víbora or Smash?, on how to answer a lob. You can also watch it on KitCut.
Why long films are the hard part
If you have tried to make a video with Claude Code or another coding agent, you know where it stops. A short animation comes out. Then every extra minute means hours of prompting, rendering, watching and fixing by hand, and keeping the voice, the look and the facts the same from the first scene to the last.
An 8-minute film is not eight one-minute films glued together. One narrator has to carry it, the pictures have to belong to one series, a fact said in chapter 1 must still be true in chapter 7, and every scene has to be timed to the words over it. That is the work KitCut does.
What went in
One brief, written like a director's notes:
- The film, chapter by chapter: a cold open, why the tennis smash fails, the choice between three overheads, one chapter for each shot, what to do when they smash at you, and four takeaways.
- A fact sheet with its sources. The brief said: every number and rule on screen comes from it, or it stays out.
- The series' look: episode 1's court, players and textures, so episode 2 looks like the same channel.
What KitCut did with it
| Step | Time |
|---|---|
| Writing the narration, painting 8 pictures, animating every scene | 83 min |
| Reviewing its own frames and fixing what it found | 10 min |
| Mixing the voice, music and sound | 1 min |
| Rendering 8 minutes of video | 17 min |
| Putting it online | 5 min |
| All of it | 1 h 56 min |
Nobody sat with it while it worked. The narrator reads 1,197 words in 78 lines in one steady voice, the ball flies on real arcs between the players, and every claim on screen carries its source, with a sources card at the end.
We are open about what we changed afterwards: we rebuilt the first 21 seconds by hand so the opening matches episode 1, and redrew four short passages where a padel player would have spotted a mistake in the picture. The narration and everything else is the film as KitCut made it.
And people watch them
Every video on Padel Tactics is made with KitCut. The channel started on October 9. Here is YouTube Studio for its first film, a 6:33 explainer, five days in:
2,402 views and 42.7 hours of watch time. The average viewer stayed for 2 minutes 43 seconds. Most of them, about 2,100, came from YouTube recommending it to people browsing; 204 came from a small ad we ran.
Long films are what YouTube rewards with watch time, and watch time is what a channel needs to grow. That is why we built KitCut to make them.
