Shots made with Root's AI movie maker
Make a short film in five steps
1. Start a project and list your shots
A project holds sequences, and each sequence holds shots. Write what happens in each one.2. Make your references
Generate a character sheet, the main locations and any props as still images. Every shot you make after this can use them.3. Generate each shot
Choose a model per shot, add the references and a prompt, and see the price before you run it. Make a few takes and approve the one you want.4. Add sound
Generate dialogue in the voice you pick, sync the lips to it, and add music. Some models also make sound with the picture.5. Cut it together
Put the approved takes on the timeline, trim them, and export. Upscale or convert to HDR first if it's going somewhere big.
What people make with it
Short films
Keep one cast consistent across dozens of shots with reference images, or train a model on a character.
Trailers and teasers
Build the key moments of a film that doesn't exist yet, to pitch it or to test it.
Ads and product films
Put a real product in every shot by starting from a photo or a 3D model of it.
Music videos
Generate performance and story shots, then cut them to the track on the timeline.
Pick the right model for each shot
No single video model wins every shot, so Root lets you choose per shot. Prices are for one five-second shot at 720p with sound, and you see the price before each run.
| Model | Good for | Longest clip | One 5 s shot, 720p |
|---|---|---|---|
| Seedance 2.5 | Long takes, many references | 30 s | $1.99 |
| Kling 3.0 | Realistic motion | 10 s | $0.73 |
| Kling Omni | Several references in one shot | 15 s | $0.65 |
| Seedance 2.0 Mini | Drafts with references | 15 s | $0.65 |

Why shot by shot
One-click script-to-video tools often give a character a new face between cuts and put the camera somewhere you didn't want it. Working shot by shot in Root, you control every one.

AI movie maker questions
Can AI make a whole movie from a script?
Not in one click, and we don't think it should. Root is built for making a film shot by shot: you decide what each shot is, the AI renders it, and you choose the take. Every shot in the finished film is one you picked.
How long can an AI video be?
Each generation is one shot. Seedance 2.5 makes clips up to 30 seconds long in one go, and most models make 5 to 15. A film is many shots edited together, so the finished piece can be as long as you like.
How much does it cost to make an AI short film?
It depends on the length and the models. A five-second Seedance 2.5 shot at 720p with sound costs $1.99 on Root, so a one-minute film of 12 shots is about $23.88 if every shot works first time. Allow for retakes. Kling Omni, Seedance 2.0 Mini and Kling 3.0 all cost less per shot.
What is the best AI movie maker?
The one that lets you use the best model for each shot and keeps all your shots and takes in one place. No single video model wins every shot, which is why Root runs Seedance, Kling, Veo, Runway and others side by side.
Is Root an AI movie trailer generator?
It's a good way to make one. A trailer is short and built from strong single shots, which is what video models do best. Generate the key shots, add a voiceover and music, and cut them on the timeline. It won't write the trailer for you in one click.
Is Root an AI short film generator?
Yes, and you direct it. Root generates every shot of a short film, you say what each shot is and pick the takes, and the characters stay the same from shot to shot.
Can I work on a film with other people?
Yes. Add people to a project and you all see the same shots, takes and approvals. Projects are private by default, and you choose who is on each one.
Do I need to download anything?
No. Root runs in the browser, and the rendering happens on our side.
