LongCat-Video: Image to Video

Animate a single frame into smooth, coherent motion. LongCat-Video preserves subject identity and style while expanding scenes into minutes-long sequences with 720p/30fps efficiency and strong temporal consistency.

Purpose-Built for Image to Video

Why Use LongCat-Video for Image to Video?

From a single reference image to compelling motion — LongCat-Video combines identity preservation, long-range coherence, and efficient inference.

Identity & Style Preservation

Start from a hero image and keep character traits, composition cues, and color palettes consistent across frames. Perfect for brand visuals, character intros, and product shots.

Keep Looks Consistent

Minutes‑Long Continuation

Natively pretrained for continuation, LongCat‑Video extends shots for minutes without color drifting or quality collapse — ideal for storytelling, walkthroughs, and showcases.

Extend Your Scene

Efficient 720p @ 30fps

Coarse‑to‑fine scheduling across temporal and spatial axes plus Block Sparse Attention enables fast, high‑fidelity Image to Video generation in minutes.

Render Faster

Unified 13.6B Architecture

One model supports Image‑to‑Video, Text‑to‑Video, and Video‑Continuation. Switch workflows without model hopping and maintain stylistic continuity.

Unify Your Pipeline

Multi‑Reward RLHF (GRPO)

Reinforcement learning with multiple rewards aligns motion quality, temporal coherence, and visual fidelity — competitive with leading open‑source and commercial systems.

FAQ

Frequently Asked Questions

What is Image to Video with LongCat‑Video?: Provide one image as the reference frame; the model animates it into a smooth, coherent clip while preserving subject identity, composition cues, and color consistency.
How does it stay consistent over time?: LongCat‑Video is pretrained for continuation and refined with multi‑reward RLHF (GRPO), improving temporal coherence, motion smoothness, and palette stability across longer shots.
How fast can I get results?: A coarse‑to‑fine schedule with Block Sparse Attention enables 720p 30fps generation in minutes on modern accelerators.
How are credits calculated?: Credits match the requested video seconds directly. Choose 480p (15fps) or 720p (30fps) for 2–8 second clips per the pricing table.
Prompt tips for Image to Video?: Specify subject action and pacing (e.g., "gentle head turn, slow camera push"), environment and lighting, and avoid conflicting instructions. For longer clips, outline beats succinctly.
