Seedance vs Kling vs Veo: how the main AI video models compare
Seedance, Kling and Veo compared on clip length, resolution, sound and start and end frames, with advice on which model suits which job.
Seedance, Kling and Veo are the model families people compare most in 2026. All three generate sound with the picture and accept a starting image. They differ in the things that matter day to day: how long a clip can be, how sharp it is, and what it does best.
We publish The AI Video Maker, which offers Seedance and Wan models. Specifications below come from published model listings in late 2026.

Seedance: long shots
The 30-second limit means one shot can hold a real moment, which means less stitching. Seedance 2.0 Mini is a cheaper option in the same family, good for longer projects.
Kling: movement
Kling is often the pick for lively, physical action.
Veo: polish
Veo is the common pick for realism and high resolution, as long as short clips are acceptable.
Which should you use?
- Trailer-style realism: Veo.
- Action and movement: Kling.
- Longer scenes and stories: Seedance.
- Best value: Wan 3.0 or Seedance 2.0 Mini.
The honest answer is to test your own prompt, since results vary with the subject. The model also matters less than you might expect once a video goes past a single shot. At that point planning and consistency matter more, which is what our AI video generator focuses on.
