}[Core Function] Kling Video O1 I2V is the image-to-video slice of Kling O1 Omni Video. [Strengths] Reasoning-enhanced generation from 1-7 reference images, 720p/1080p, duration 3-10s (single image only 5 or 10). [Best For] Complex physical motion grounded in reference frames. [Limitations] No native audio; no aspect_ratio (follows first frame); duration capped at 10s. [Routing] Prefer this for O1-quality I2V; use Kling Video O1 V2V when a source video is required.
