Video models that make vertical clips
What one vertical clip of about 10 seconds costs on Root, made from a prompt, at 720p where the model offers it, with sound where the model makes it. 100 credits is $1.

Kling 2.6 and Kling 2.5 Turbo also make vertical clips; the app shows their price before you run. “Up to” is the most it can cost; you are charged what the model reports it used. Prices marked “about” are for work that runs on Root's own machines: the price shown before the run is an estimate, and the bill is set by how long the run really takes.
Getting the vertical shape right
- Choose 9:16 in the model's ratio setting before you run it.
- Starting from an image? Make the image vertical first. The four Seedance models and MiniMax H3 (Hailuo 3.0) keep the shape of the first frame whatever ratio you pick.
- Many of Root's image models make 9:16 stills too, such as Nano Banana Pro, Nano Banana or GPT Image 2, so the first frame can be vertical from the start.
- Keep the subject in the middle of the frame, clear of the edges, where the app you post to puts its buttons and captions.
- Ask for the sound you want in the prompt: the line spoken, the music, the noise of the place.
A 15-second vertical ad, priced
One vertical image as the first frame, a few cheap drafts to find the movement, then the final take on a stronger model.
| Step | Model | How many | Each | Total |
|---|---|---|---|---|
| A vertical first frame | Seedream 5.0 Pro | 1 | $0.06 | $0.06 |
| Draft takes, 15 s, 720p, with sound | Seedance 2.0 Mini | 3 | up to $1.98 | up to $5.94 |
| The final take, 15 s, 720p, with sound | Seedance 2.5 | 1 | up to $6.04 | up to $6.04 |
| The whole ad | up to $12.04 |
