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 2.1 Turn a photo into a short moving shot, or start from text with Master. - Standard: one photo. Pro: one or two photos. Master: text or one photo. - Choose 5 or 10 seconds. A separate negative-prompt field is available. - Standard and Pro cannot start from text alone. - Complex hand movements and sharp turns need close inspection. ## What to inspect with Gemini Omni 1.2 Flash Video from text, frames and references, editing and extension. - Text: the result is created from a written description. - First and last frame: two photos set how the clip starts and ends. - The result length is 3 to 15 seconds. - At most 10 photos as input. ## 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 2.1 Turn a photo into a short moving shot, or start from text with Master. ](https://mixerai.org/en/knowledge/video/kling-2-1/) [ Gemini Omni 1.2 Flash Video from text, frames and references, editing and extension. ](https://mixerai.org/en/knowledge/video/gemini-omni-1-2-flash/) ## FAQ Which is cheaper: Kling 2.1 or Gemini Omni 1.2 Flash?
