Playground

Kling 1.6 Multi Pro boosts image-to-video generation by 195% vs Kling 1.5, with improved prompt understanding, physics and visuals. Ready-to-use REST inference API, best performance, no coldstarts, affordable pricing.

Features

Kling V1.6 Multi-Image-to-Video Pro is Kuaishou’s advanced multi-image-to-video generation model that creates stunning videos from multiple reference images. Upload up to 4 images, describe the motion you want, and generate cinematic videos that blend and animate your source images seamlessly.

Why It Stands Out

• Multi-image input: Use up to 4 reference images for richer, more complex video generation.
• Pro-level quality: Premium output with exceptional detail and motion coherence.
• Prompt-guided motion: Describe camera movements, actions, and transitions.
• Negative prompt support: Exclude unwanted elements for cleaner outputs.
• Flexible aspect ratios: Choose from 16:9, 9:16, 1:1 to fit any platform.
• Commercial-grade output: Professional quality suitable for ads and branded content.

Parameters

How to Use

1. Upload your images — add 1 to 4 reference images via drag and drop or public URL.
2. Write a prompt — describe the motion, camera movement, and visual style you want.
3. Add a negative prompt (optional) — specify elements to exclude.
4. Set duration — choose 5 or 10 seconds.
5. Select aspect ratio — choose the format that fits your platform.
6. Click Run and wait for your video to generate.
7. Preview and download the result.

Best Use Cases

• Automotive & Product Ads — Create dynamic commercials from product photos.
• Travel & Lifestyle — Animate destination photos into cinematic sequences.
• Multi-Scene Storytelling — Blend multiple images into cohesive narratives.
• Marketing & Advertising — Produce high-quality branded video content.
• Creative Projects — Generate unique videos from artwork and photography.

Pricing

Pro Tips for Best Quality

• Use high-resolution, well-lit source images for optimal results.
• Multiple images work best when they share visual consistency (style, lighting, subject).
• Be detailed in your prompt — describe camera movement, transitions, and atmosphere.
• Include cinematic keywords like “aerial drone shot,” “low-angle tracking,” “commercial film look.”
• Use negative prompts to reduce artifacts like blur or distortion.
• Choose 16:9 for widescreen commercials, 9:16 for social media verticals.

Notes

• Maximum 4 reference images per generation.
• Ensure uploaded image URLs are publicly accessible.
• Processing time varies based on duration and current queue load.
• Please ensure your prompts comply with content guidelines.
