FastVideo

FastVideo is a lightweight framework for accelerating large video diffusion models.

FastVideo currently offers: (with more to come)

• FastHunyuan and FastMochi: consistency distilled video diffusion models for 8x inference speedup.
• First open distillation recipes for video DiT, based on PCM.
• Support distilling/finetuning/inferencing state-of-the-art open video DiTs: 1. Mochi 2. Hunyuan.
• Scalable training with FSDP, sequence parallelism, and selective activation checkpointing, with near linear scaling to 64 GPUs.
• Memory efficient finetuning with LoRA, precomputed latent, and precomputed text embeddings.
