Seedance vs Kling vs Veo: which AI video model should you use?

Seedance, Kling and Veo are the three model families people compare most when choosing an AI video generator in 2026. All three now generate sound with the picture, all three accept a starting image, and all three are good. They differ in the things that matter day to day: how long one clip can be, how sharp it is, what it costs, and what kind of footage each one does best.

Specifications and prices below are from the models' published API listings in October 2026. Prices are approximate per second of output and change often; consumer apps price differently. We publish the cartoon video creator, which uses Seedance and Wan models.

Side by side

Seedance: longest shots and the best value for stylised video

Seedance's headline advantage is length. Seedance 2.5 renders a single continuous shot of up to 30 seconds — twice Kling's limit and almost four times Veo's — so a whole scene can play out without a cut. It holds character designs well through a shot, handles stylised looks such as 2D cartoons, anime and 3D animation convincingly, and accepts start and end frames for precise control.

Seedance 2.0 is the higher-resolution option (up to 4K) with a 15-second limit, and its Fast and Mini versions are among the cheapest ways to get good video with sound.

Pick Seedance for: cartoons, storytelling, consistent characters, longer shots, and volume on a budget.

Kling: motion and physicality

Kling 3.0 is widely praised for how things move — weight, momentum, dancing, sport, fights and dynamic camera work. Clips run from 3 to 15 seconds at 720p, with start and end frames. Sound is available but adds to the price.

Pick Kling for: action, dance, product spins and anything where the movement is the point.

Veo: realism and polish

Veo 3.1 produces the most cinematic, lifelike footage of the three, with natural lighting, realistic faces and well-mixed sound, up to 4K. The trade-off is length — 4, 6 or 8 seconds per clip — and price at full quality. The Fast and Lite versions bring the cost down considerably.

Pick Veo for: realistic people and places, commercials, and short premium shots.

Which is best for cartoons?

For animated, stylised content, Seedance is the strongest fit: the long shots suit storytelling, and it keeps a cartoon look consistent rather than drifting towards realism. Kling is a good second choice for energetic cartoon action. Veo's strength — photorealism — matters least for cartoons.

Whichever model you choose, a single clip is still a single shot. To turn an idea into a complete cartoon — several scenes, the same characters throughout, voices and music — our cartoon video creator plans the story and makes the whole film for you, from a few seconds up to 5 minutes (20 on the Pro plan), on Seedance 2.5, Seedance 2.0 Mini or Wan 3.0.
