Kling o3 4K Video Edit edits an existing video at the 4K tier. Upload your source video and describe the change in the prompt.
In your prompt, use @Video1 for the source video, @Image1 and @Image2 for reference images, and @Element1 and @Element2 for elements. These labels connect each instruction to the video, image or element it describes.
Elements are characters or objects you want to include in the edit. Supply a clear front view of each one. Additional views help define its appearance from other angles. When a video is supplied, reference images and elements are limited to four in total.
Source video requirements: .mp4 or .mov, 3 to 15 seconds, 720 to 3840 pixels, and at most 200MB. Keep Original Audio preserves the source audio track. Set the length slider to the actual duration of your input video, since pricing is calculated from it.
