Inspect motion continuity, character and object consistency, physics and contacts, camera behavior, temporal deformation, in-clip cuts and audio synchronization. ## What to inspect with Kling 4.0 A clip of up to 30 seconds from text and references or from a chain of keyframes: named characters, voice samples and exact frames. - Text and references: up to 10 reference photos and 5 videos, up to 7 characters (2–4 photos or one 3–8 second video clip each) and up to 3 voice samples. The Video sound switch applies only to reference videos. - Keyframes: a first frame, a last frame and up to 8 middle frames. The total number of frames depends on the duration and never exceeds 10. - The modes do not mix: Keyframes accepts no video, and characters and voices belong only to Text and references mode. - A hero photo must be at least 300 pixels on the short side; a video character needs at least 700 pixels and one continuous shot. ## What to inspect with Seedance 2.0 A short scene with your character, motion and sound, with Mini, Fast and Pro versions to choose from. - Generate from text, first and last frames, or a set of references. - In Mixer AI, Mini and Fast offer 480p and 720p; Pro adds 1080p and 4K. - Version and resolution are separate settings. Selecting Pro does not automatically select 1080p or 4K. - Reference video adds billable time. A lower rate with video can still produce a larger total. ## How to run a fair comparison - Fix the scene, the first frame (if both models accept one), the duration and the resolution. - Judge motion, not stills: faces, hands and objects should hold across the whole clip and at cuts. - If sound matters, listen to it separately: dialogue, effects and lip sync differ between models. - Price a finished clip, not a second: the per-second rate times your real duration, rounded up once. ## Sources Prices, availability and specifications come from the Mixer AI catalog. This is not an independent test: try both models on the same task before choosing. - [Prices and availability — Mixer AI catalog](https://mixerai.org/knowledge/catalog.json) ## What we compare [ Kling 4.0 A clip of up to 30 seconds from text and references or from a chain of keyframes: named characters, voice samples and exact frames. ](https://mixerai.org/en/knowledge/video/kling-4-0/)[ Seedance 2.0 A short scene with your character, motion and sound, with Mini, Fast and Pro versions to choose from. ](https://mixerai.org/en/knowledge/video/seedance-2/) ## FAQ Which is cheaper: Kling 4.0 or Seedance 2.0?
