About Kling 4.0 Reference to Video API
Kling 4.0 Reference-to-Video generates 3-30 second clips at 720p or 1080p with native audio from your own materials: up to 10 reference images, 5 reference videos, 7 named elements (2-4 images or a 3-8 second character video each) and 3 voices, with at most 15 materials in total. Mention each material in the prompt with @image_1, @video_1 or @name. With no materials it behaves as plain text-to-video. To direct a clip from still frames, use [Kling 4.0 Keyframe to Video](/playground/kling-4.0-keyframe-to-video).
