How to Install and Run LongCat-Video Locally: Generate Stunning Long Videos with AI
Creating realistic, dynamic, and extended video content from simple text prompts has long been one of AI’s most ambitious goals, and LongCat-Video marks a major leap forward in that journey. With an impressive 13.6B parameters, this foundational video generation model unifies Text-to-Video, Image-to-Video, and Video-Continuation within a single, powerful architecture. Whether you want to bring a static image to life, extend existing footage seamlessly, or generate entirely new cinematic scenes from text, LongCat-Video handles it all with remarkable coherence and visual fidelity. Its native long video generation capabilities, pretrained on Video-Continuation tasks, allow it to produce minutes-long 720p, 30fps videos without the typical color drift or loss in quality seen in other models. Thanks to its coarse-to-fine generation and Block Sparse Attention, it achieves an optimal balance between performance and efficiency, making high-resolution video generation possible even on local setups.
