Overview

Kling v2.1 Image-to-Video (Pro) turns one source image, an optional tail image, and a motion prompt into a short generated video using Kuaishou's Kling v2.1 Pro model. Use it for product motion, social creative, ad concepts, and transition drafts when an optional ending image should guide the result.

Use cases

  • Animate a product or campaign still into a 5- or 10-second video draft.
  • Add tail_image_url when the video should move toward a specific ending visual.
  • Use cfg_scale to tune how closely the video follows the prompt.
  • Use negative_prompt to reduce blur, distortion, low quality, or other unwanted artifacts.

Input tips

  • Provide a public image_url that can be fetched without login.
  • Add tail_image_url only when the ending image should guide the final part of the video.
  • Write a prompt under 2,500 characters describing action, camera movement, pacing, and visual style.
  • Choose 5 or 10 seconds; 5 seconds is the default.
  • Leave cfg_scale and negative_prompt at defaults unless prompt adherence or artifacts need tuning.

Expected output

The AI Tool returns one generated video object with a downloadable URL, duration, optional content type, file name, file size, width, height, and cost metadata. The shared video output view renders the video for playback, review, and download.

Caveats

  • Source and tail image URLs must be public and reachable.
  • Tail-image guidance influences the ending but does not guarantee exact timing, framing, or motion.
  • This AI Tool does not expose audio, seed, aspect-ratio, or resolution controls.
  • cfg_scale and negative_prompt guide the result but do not guarantee exact motion or artifact removal.
  • Generated motion, people, products, brand marks, and text should be reviewed before use.
