LongCat-Video – Unified AI Model for Text-to-Video, Image-to-Video & Video Continuation

LongCat-Video is a powerful, production-ready AI video generation model that transforms text, images, or partial clips into minutes-long, coherent, and visually consistent videos. Built with a unified architecture, LongCat-Video handles Text-to-Video, Image-to-Video, and Video-Continuation within a single framework — making it one of the most advanced and flexible AI video creation systems available today.

Unlike traditional short-clip generators that struggle beyond a few seconds, LongCat-Video is specifically engineered for extended narratives, long-form motion, and consistent identity across minutes of footage.

🎬 Key Features of LongCat-Video

1. Unified Architecture for All Video Tasks

LongCat-Video merges three major video generation capabilities into a single foundational model:

• Text-to-Video – Generate high-quality video directly from prompts
• Image-to-Video – Animate or extend static images
• Video-Continuation – Extend existing footage into longer sequences

This means creators don’t need multiple models — LongCat-Video serves all use cases with consistent quality and behavior.

2. Long Video Generation (Minutes-Long Output)

Trained natively on Video Continuation, LongCat-Video produces:

• Minutes-long videos
• No color drift
• No identity collapse
• Smooth, consistent motion

It excels at long-form storytelling, explainer videos, animations, product stories, creative sequences, and cinematic content.

3. Fast, Efficient Inference

LongCat-Video uses a coarse-to-fine generation strategy across spatial and temporal dimensions to boost performance.

Key technical advantages:

• 720p resolution
• 30fps smooth motion
• High efficiency at scale
• Block-Sparse Attention for faster computation
• Production-ready speed

Most videos are generated within minutes, even at extended lengths.

4. State-of-the-Art Performance (RLHF + GRPO)

LongCat-Video is trained using multi-reward RLHF via Group Relative Policy Optimization (GRPO).

This ensures:

• High subject consistency
• Stable motion
• Accurate camera intent
• High benchmark performance
• Quality comparable to top commercial video models

It outperforms many open-source and commercial alternatives in long-form consistency.

📘 How to Use LongCat-Video

(3-Step Workflow)

1. Describe or Upload

Start with:

• A detailed text prompt
• A still image
• A partial video clip

LongCat-Video understands style, subject identity, motion intent, and camera movement.

2. Generate & Extend

Produce your first clip, then extend it using video-continuation:

• Add more narrative
• Continue scenes
• Build multi-minute sequences

Perfect for long-form YouTube content, product walkthroughs, explanations, trailers, and storytelling.

3. Refine & Export

Fine-tune:

• Length
• Motion
• Framing
• Composition

Export 720p/30fps, ready for editing software like Premiere Pro, DaVinci Resolve, or Final Cut.
