LongCat Video

Q: What is LongCat-Video?

LongCat-Video is Meituan's unified video generation model supporting Text-to-Video, Image-to-Video, and Seamless Video Continuation. It creates minute-long 720p/30fps outputs with temporal coherence and efficient inference.

Q: How is it different from short-clip generators?

Unlike typical short-video models, LongCat is trained on continuation tasks for long-context understanding, ensuring stable characters, consistent motion, and color coherence.

Q: What resolutions and frame rates does it support?

It generates 720p videos at 30fps using sparse attention and a multi-stage generation process to balance quality and efficiency.

Q: How fast is the generation process?

With its efficient inference design, LongCat can generate minute-long videos within practical runtimes.

Q: Can it extend existing videos?

Yes. LongCat predicts future frames from existing footage, creating smooth and context-aware video continuations.

Q: How does it maintain long-term consistency?

Through continuation pretraining and Temporal Coherence Optimization, ensuring stability in identity, color, and motion across sequences.
