Kling 2.1, Priced Per Clip
Kling's cinematic motion model — ✦30 for a five-second clip, on credits that never expire.
Kling 2.1 is Kuaishou's video model, known for physical plausibility — cloth that falls correctly, water that behaves like water, camera moves that hold their geometry. In Raduga it runs both text-to-video and image-to-video, so you can start from a written scene or animate a still you already have.
What Kling 2.1 is best at
- Product and scenery shots where physics gives the frame away
- Animating an existing photo without re-generating the subject
- Camera-led shots — pair it with a one-tap move like crash zoom or 360 orbit
What it costs in Raduga
✦30 credits for 5s (about 54¢ on the $9 Spark pack); 10s also available. There is no subscription — you buy credits once and they never expire, and any generation that fails is refunded to your balance automatically.

How to run it
Open the studio, pick Kling 2.1 from the model list, write your prompt (or tap a preset), and generate. Everything lands in your gallery, where any result can be edited, upscaled 4×, background-removed or animated — all on the same balance.
Kling is the best default for image-to-video work: strong motion coherence at the lowest per-clip cost of our three video models. Step up to Seedance 1.0 Pro (✦40) when you specifically need crisp 1080p, or Hailuo 02 (✦35) when a human subject has to emote.
