{"servers":[{"url":"https://api.modellix.ai/api/v1/kling/kling-v3-omni-video"}],"post":{"description":"[Core Function] Kling V3 Omni Video V2V is a multimodal video-to-video endpoint that edits or restyles existing footage using prompt plus optional image and video references. [Strengths] It focuses on source fidelity and subject consistency for Omni-style edit workflows, combining prompt guidance with images and videos inputs so changes stay grounded in the original clip. [Best For] Highly recommended for: reference-faithful video edits, restyling existing takes, keeping characters or products consistent while changing motion or scene instructions, and short-form post workflows that start from real footage. [Limitations] Do NOT use this model for pure text-to-video from scratch; use Kling V3 T2V, Kling V3 Omni T2V, or Kling V3 Turbo T2V. Do NOT use it when you only have a still image and no source video; use Kling V3 I2V or Kling V3 Omni I2V. Do NOT use it for deep physics-reasoning generation better served by Kling Video O1. [Routing] Choose Kling V3 Omni Video V2V when the user already has video to edit or transform and mentions Omni or multimodal references. Prefer Kling Video O1 when reasoning-heavy generation is the goal rather than source-based editing.","operationId":"klingV3OmniVideoAsync","requestBody":{"content":{"application/json":{"examples":{"multi_shot_intelligence":{"summary":"Omni V2V with reference video","value":{"audio":"off","images":["https://example.com/reference-frame.jpg"],"multi_shot":true,"prompt":"A woman leaves a subway station and walks into a rainy cyberpunk street, then the camera tracks beside her","resolution":"1080p","videos":["https://example.com/source-video.mp4"]}},"video_edit":{"summary":"Video editing flow (base video)","value":{"audio":"original","prompt":"Transform the source clip into a cinematic sci-fi sequence with brighter neon lighting","resolution":"1080p","videos":["https://example.com/source-video.mp4"]}}},"schema":{"description":"Kling V3 Omni V2V — category slice of kling-v3-omni. videos required; images optional; element not exposed.
