Kling Video O1 Reference-to-Video

Kling Video O1’s Reference-to-Video mode generates dynamic, high-fidelity videos by leveraging one or more reference images or clips of a character, prop, or scene.

Kling Video O1 API Overview

Kling Video O1 Reference-to-Video by Kuaishou delivers breakthrough subject-consistent video generation from image references. This unified multimodal model preserves character, prop, and scene identity across entirely new scenarios, powered by advanced feature extraction.

Technical Specifications

  • Input Support: Single or multiple reference images (up to 4 viewpoints per element) in JPG, JPEG, PNG formats; optional video references up to 10s, 200MB, 2K resolution.​
  • Output Capabilities: Videos from 5-10 seconds; resolutions up to 2K (1080p standard); 30fps; aspect ratios including 16:9.​​
  • Model Architecture: Unified multimodal engine with Chain of Thought (CoT) reasoning, multi-element fusion, and vision-language processing for precise identity retention.

Performance Benchmarks

Kling Video O1 excels in identity consistency and motion quality. Internal tests show 247% improvement over Google Veo 3.1 and 230% over Runway Aleph in reference generation tasks.​

  • Superior frame stability reduces flickering in multi-subject scenes.
  • Enhanced reasoning via CoT boosts prompt accuracy by analyzing inputs before rendering.

Model Comparisons

vs Google Veo 3.1: Kling O1 outperforms by 247% in reference fidelity, offering better multi-view fusion without coherence loss; Veo lags in complex subject interactions.​

vs Runway Gen-4.5: Superior identity retention across angles makes Kling ideal for pro-grade consistency; Runway focuses more on text-driven motion but struggles with multi-references.​

vs Hailuo 2.3: Kling's CoT reasoning delivers smoother physics and camera work; Hailuo excels in speed but trails in subject stability for extended clips.
