LongCat Video Overview
A unified 13.6B foundational model for text-to-video, image-to-video, and long-form continuation.
LongCat-Video is a foundational video generation model with 13.6 billion parameters, developed by Meituan’s LongCat team. It delivers strong performance across text-to-video, image-to-video, and video-continuation—three tasks unified in a single architecture so teams can ideate, animate, and extend stories without switching models.
The model is designed as a first step toward world models: it excels at efficient, high-quality long video generation. Native pretraining on video-continuation tasks enables minutes-long narratives while preserving subject identity, lighting, and color consistency across extended durations.
For production teams, LongCat Video outputs 720p resolution at 30 frames per second within practical runtimes. A coarse-to-fine strategy along temporal and spatial axes, combined with Block Sparse Attention, keeps inference efficient even at higher resolutions—suitable for SaaS dashboards, marketing pipelines, and rapid creative iteration.
Quality is reinforced through multi-reward reinforcement learning from human feedback (RLHF) using Group Relative Policy Optimization (GRPO). Benchmarks cited in public materials show performance comparable to leading open-source video models and recent commercial solutions.
Whether you start from a text brief, a product photo, or an existing clip, LongCat Video gives you one consistent backbone for short social loops, ad concepts, and longer story-driven sequences—ready to export as edit-friendly MP4 assets.

Cinematic Text-to-Video
A graceful ballerina in a flowing white dress dances slowly on the surface of a calm shallow lake at sunrise. She gently extends her arms and turns her body in an elegant ballet pose, creating soft ripples around her feet. The water reflects her full figure like a mirror, with a perfect inverted reflection beneath her. Mist floats above the lake, distant forest silhouettes line the horizon, and the sky glows with soft pastel orange, pink, and blue morning light. Cinematic wide shot, dreamy atmosphere, smooth slow camera movement, natural body motion, realistic water ripples, elegant choreography, soft haze, high detail, serene and poetic mood.
Surreal Scene Generation
Macro cinematic close-up of a ripe red strawberry wrapped inside a transparent crystal lattice shell on a warm wooden table. Sunlight shines through the glass-like net, creating sparkling reflections, rainbow highlights, and soft shadows. Shallow depth of field, slow camera push-in, luxurious surreal product shot, ultra realistic, high detail.
Product Image-to-Video
First-person view of a humanoid robot at a wooden office desk. Two white robotic arms with black joints interact with everyday objects: a laptop, glass of water, smartphone, teddy bear, and tissue box. The robot hand slowly reaches for the glass with precise finger movement. Warm daylight, modern workspace, realistic shadows, smooth stable camera, cinematic realism.
Portrait Motion from Still
Gentle head movement, natural blinking, soft background bokeh shift, studio lighting unchanged, realistic skin texture.
Long-Form Continuation
First-person POV mountain biking downhill on a rocky alpine trail, handlebars and gloved hands visible, turquoise lake and snow-capped mountains in the background, bright sunlight, GoPro wide-angle view, fast motion, slight camera shake, realistic outdoor adventure footage.
Multi-Beat Narrative Extension
Extend establishing shot into follow-up beats—camera intent and subject identity remain stable as duration increases past one minute.
