AnimateDiff-Lightning
AnimateDiff-Lightning is a lightning-fast text-to-video generation model. It can generate 16-frame 512px videos in a few steps. For more information, please refer to our research paper: AnimateDiff-Lightning: Cross-Model Diffusion Distillation. We release the model as part of the research.
Our models are distilled from AnimateDiff SD1.5 v2. This repository contains checkpoints for 1-step, 2-step, 4-step, and 8-step distilled models. The generation quality of our 2-step, 4-step, and 8-step model is great. Our 1-step model is only provided for research purposes.
Recommendation
AnimateDiff-Lightning produces the best results when used with stylized base models. We recommend using the following base models:
Realistic
Anime & Cartoon
Additionally, feel free to explore different settings. We find using 3 inference steps on the 2-step model produces great results. We find certain base models produces better results with CFG.
