Generating Long, High-Quality AI Videos with LongCat-Video in ComfyUI (Google Colab Setup)
A 27-minute 15fps video generated with ComfyUI on Google Colab. LongCat-Video is an AI project that pushes the limits of video generation. Unlike most AI video models that degrade in color or consistency after a few seconds, LongCat-Video enables generating videos longer than 30 seconds, all while maintaining sharp image quality and stable colors . The models and code were optimized for ComfyUI by Kijai , one of the major contributors to the ComfyUI ecosystem. This optimization makes it much easier to experiment with LongCat-Video and generate long, coherent video sequences right from your browser. Running LongCat-Video on Google Colab I’ve created a Google Colab notebook that automatically sets up ComfyUI with the LongCat-Video models. So far, I’ve tested it on the L4 GPU , but it should also work on the free T4 if you reduce the number of frames generated per sequence and set blocks_to_swap to 0 if the RAM crashes with the default settings. ...
