The architecture of FramePack addresses two major challenges in video generation: forgetting and drift. Forgetting refers to the model's difficulty in retaining earlier content over time, while drift causes quality degradation due to error accumulation in long sequences. FramePack tackles these issues with a frame compression mechanism and an anti-drifting sampling method that uses bidirectional context rather than strict causal dependencies. This results in smooth, stable videos without the typical decline in quality seen in other models. Additionally, FramePack supports progressive frame-by-frame video generation, enabling real-time previews and iterative refinement of outputs, which enhances user control and creative flexibility.
FramePack is open source and optimized for practical use, supporting Nvidia RTX 30XX, 40XX, and 50XX GPUs with minimal VRAM requirements. It can generate videos from 5 to 60 seconds at 30 frames per second, with generation speeds ranging from 1.5 to 2.5 seconds per frame on high-end GPUs like the RTX 4090. The model is highly customizable, allowing users to fine-tune compression patterns and frame importance to suit different creative needs. Its efficient design democratizes video generation technology, making it accessible for both personal experimentation and professional projects without requiring expensive hardware or complex setups.
