Welcome to FastVideo#
FastVideo is a unified framework for accelerated video generation.
It features a clean, consistent API that works across popular video models, making it easier for developers to author new models and incorporate system- or kernel-level optimizations. With FastVideo’s optimizations, you can achieve more than 3x inference improvement compared to other systems.
Key Features#
FastVideo has the following features:
State-of-the-art performance optimizations for inference
