Kling O1 - Reference to Video

Try Kling O1 - Reference to Video in the Workbench

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

Model ID: kling-video-o1-reference-to-video Kling O1 - Reference to Video is a multimodal video generation model designed for reference-guided video synthesis. It excels in transforming reference videos or images into new sequences while preserving motion dynamics, camera movements, and visual styles for consistent outputs. Some other noteworthy features of Kling O1 - Reference to Video include image-to-video transformations, multi-reference image conditioning (up to 7 images), scene extension with continuity, and support for start/end frames or keyframes.
