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.
Which one to pick
- For long takes: Seedance 2.5, up to 30 seconds in one clip.
- For 4K: Seedance 2.0, Kling 3.0, Kling 3.0 Omni and Veo 3.1.
- For sound made with the picture: all four Seedance models, Kling 3.0, Kling 3.0 Omni, Kling 2.6, Veo 3.1, FLUX 3 Video and MiniMax H3 (Hailuo 3.0).
- For a low price while you work out a shot: Kling 2.5 Turbo, $0.25 for 5 s, 720p, the cheapest clip in the table.
- For a character or product that has to look the same in every shot: a model that takes reference images, such as Seedance or Kling 3.0 Omni.
Why use them through Root
Each model has its own site, its own plan and its own credits. On Root they share one balance, one project and one place where every take is kept, so you can make a shot with one model and its next take with another.
The price of every run is shown before it starts. Most of the models also run by API and from Claude and ChatGPT, under the same account.
