WaveSpeedVideo generation from images and video
Kling O3 is a video generation model published by Kling and served through the Wavespeed provider on MindStudio. It accepts text prompts alongside source images and video inputs, enabling workflows such as image-to-video animation, video-to-video transformation, and multi-reference image generation. The model was added to MindStudio in February 2026 and carries the LATEST tag, indicating it represents the most recent release in the Kling video model line.
Kling O3 is designed for use cases that require fine control over video composition, including specifying a first frame image, a last frame image, duration, and aspect ratio. It also supports audio generation and the option to preserve original sound from a source video. Pricing starts at $0.24 per second of generated video, making it suitable for projects where per-second cost is a meaningful planning factor.
What Kling O3 supports
Image-to-Video
Animates a still image into a video clip by accepting a first frame image and optionally a last frame image to define the motion arc.
Video-to-Video
Accepts a source video input and transforms or extends it, with an option to retain the original audio track from the uploaded clip.
Audio Generation
Generates audio alongside the video output via a dedicated toggle, or preserves the original sound from a source video when preferred.
Multi-Reference Images
Accepts an array of reference images to guide visual style or subject consistency across the generated video.
Aspect Ratio Control
Allows selection of output aspect ratio via a toggle group, enabling landscape, portrait, or square video formats.
Duration Setting
Accepts a numeric duration input so users can specify the length of the generated video clip before generation begins.
