Try Kling O3 Pro: Image-to-Video in the Workbench Run this model interactively, tune parameters, and compare outputs.
Model ID: kling-video-o3-pro-image-to-videoThe Kling Video O3 Pro series specializes in image-to-video generation, transforming a single input image into dynamic video sequences guided by textual descriptions of motion and action. It supports customizable duration (1-10 seconds), aspect ratios (16:9, 9:16, 1:1), motion strength, and advanced inference parameters like guidance scale and number of steps for fine-tuned control over output quality and style. Ideal for creating realistic animations, product demos, and creative video content from static visuals.
Example request Use the Workbench as a request builder: configure parameters for this model in the UI, then open the API tab to copy the exact cURL or Python call. 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. Minimal
