Overview

Generate videos from text prompts using the Kling V3 Omni model. V3 Omni introduces:
  • First/Last frame control — provide first_frame and last_frame images to guide video generation
  • Multi-shot video — generate multi-scene videos via multi_shot and multi_prompt
  • Audio generation — produce synchronized audio with sound: "on"
  • Extended duration — 3 to 15 seconds
  • Element references — reference up to 7 elements (images + elements combined)
  • Standard / Professional modes — 720P (std) or 1080P (pro) output
