Kling O3 4K: Image-to-Video

Try Kling O3 4K: Image-to-Video in the Workbench

Run this model interactively, tune parameters, and compare outputs.

Model ID: kling-video-o3-4k-image-to-video Kling O3 4K Image-to-Video animates a static image into native 4K (3840x2160) motion in a single pass, with no upscaling step. The output’s aspect ratio is inherited from the input image, and an optional end frame can anchor the final shot for a specific transition. Supports clips from 3 to 15 seconds, optional native synchronized audio, and preserves the source image’s stylistic look, color, and lighting throughout the clip.

Sync
Async
Async with SSE

This blocks until the video is ready (typically 5-15 minutes). Prefer Async or Async with SSE for anything beyond quick experimentation.See the video generation reference for more details.
