All of them, plus Grok Video and Grok 1.5, sit behind one account and one balance. Templates arrive with the model already chosen, so the grid below shows each engine on a job it suits. On Create video you pick the model yourself and can test one idea on two of them.
Face consistency: Seedance 2.0 and 2.5 Omni
Seedance templates are written around a strict identity reference. In Rooftop Party Flip the hero performs stunts in one continuous take at a night party, and the prompt asks for the face to match the starting frame throughout. Dragon Awakening places you on a hilltop above a forested ravine. Reach for Seedance when a person should stay recognizable while a lot happens around them.
Camera motion: Kling 3.0 against Seedance 2.5 Omni
Kling 3.0 templates imitate a sports broadcast. In Game Day a stadium camera finds you in the crowd and a telephoto lens slowly zooms in; Hockey Broadcast Cameo holds a long-lens shot with slight shake and TV grain. Seedance 2.5 Omni goes the other way in Frozen Moment Fly-Through: one floating handheld camera weaves through a scene stopped mid-motion.
Style and sound: Veo 3.1 and VEO Omni 1.1
When the look itself should change, the Veo templates lead. Anime Transformation opens a finger frame that reveals your anime version, then turns the whole shot anime, with music. VEO Omni 1.1 runs Reality Meets Manga, where your fingertips open a window into a black-and-white manga world. So in kling vs veo terms: Kling for footage that looks real, Veo for restyling.
Grok and testing models yourself
Grok Video and Grok 1.5 have no templates in this grid, so the fair test is your own. Open Create video, write one scene, run it on Grok and then on Seedance 2.0 or Kling 2.6, and keep the clip that reads better. You see what each engine will charge before pressing run, so a side-by-side test holds no surprises.
Limits worth knowing
Even the strongest model can drift on a face, and two runs of one prompt rarely match, so plan for a retry. Use your own photos or photos of people who agreed, never celebrities. Expect a clip within several minutes, or more if the queue is crowded. Facts like resolution or watermarks are not covered here.

FAQ
What is the best AI video generator in 2026?
There isn't one winner for every task. On MarketVideo, Seedance suits people in motion, Kling 3.0 suits broadcast looks and multi-shot scenes, and Veo 3.1 suits stylized clips with music. Each template already uses the model that fits its scene.

Seedance vs Kling: which keeps a face better?
Both aim to keep your features. Seedance templates spell out strict identity rules for action such as stunts and flips, while Kling 3.0 keeps motion small and believable, like a spectator turning their head in Game Day. Calm shot: start with Kling. Fast action: start with Seedance.
Do I have to pick a model for every video?
Only on Create video. Every template has its model set in advance, so you upload a photo and run it. Create video lists Veo 3.1, Kling 3.0, Seedance 2.5 Omni, Grok Video and others, and the finished clip downloads as a normal file.
