LongCat-Video Features
Discover the powerful capabilities of LongCat-Video, the unified video generation model designed for professional workflows.
Unified architecture for multiple tasks
LongCat-Video unifies Text-to-Video, Image-to-Video, and Video-Continuation tasks within a single video generation framework. The LongCat-Video model natively supports all these tasks with a single architecture and consistently delivers strong performance across each individual task. With LongCat-Video, you get one powerful model for all your video generation needs.
Long video generation
LongCat-Video is natively pretrained on Video-Continuation tasks, enabling the LongCat-Video model to produce minutes-long videos without color drifting or quality degradation. LongCat-Video excels at generating extended narratives while maintaining visual consistency throughout.
Efficient inference
LongCat-Video generates 720p, 30fps videos within minutes by employing a coarse-to-fine generation strategy along both the temporal and spatial axes. The LongCat-Video architecture leverages Block Sparse Attention to further enhance efficiency, particularly at high resolutions, making LongCat-Video production-ready for demanding workflows.
Strong performance with multi-reward RLHF
Powered by multi-reward Group Relative Policy Optimization (GRPO), comprehensive evaluations on both internal and public benchmarks demonstrate that LongCat-Video achieves performance comparable to leading open-source video generation models as well as the latest commercial solutions. LongCat-Video's advanced RLHF training ensures optimal quality across all generation tasks.

"LongCat-Video let our social team turn a single product shot into a minute-long hero sequence. Identity stayed locked, motion felt natural, and export was fast enough for our weekly drops."
"As a solo YouTuber, I used LongCat-Video to continue scenes from one still frame. I got smooth 720p/30fps clips without switching tools. It changed my production cadence."
"We prototyped ad concepts in hours, not days. LongCat-Video kept characters consistent across multiple beats, so our clients could approve story logic before we shot anything."
"LongCat-Video nailed long-form continuity for our explainer series. Scene extensions matched lighting and camera intent—no weird color drift, no identity collapse."
"I started with a single image and LongCat-Video handled image-to-video and continuation in one flow. The unified pipeline cut revision loops in half for our launch campaign."
"For game trailers, LongCat-Video is perfect for stitching beats together. It extends action with coherent motion, then lets us selectively regenerate moments to refine pacing."
"Client asked for "a longer story, same look." LongCat-Video kept wardrobe, lighting, and style consistent while we pushed duration past a minute. That's rare."
