FramePack-Dev

FramePack-Dev is a fork that adds the following features to FramePack and FramePack LoRAReady.

• Standalone execution. Run uv run demo_gradio.py
• LoRA directories by argument. --lora-dirs
• Embedding metadata to the generated video.
• Strict Total Frames specification considering Latent Window Size
• No Windows support. Use WSL2.

Disclaimer

I have no intention of maintaining this repository for a long time.
I believe that the new features implemented in this repository should be incorporated into the FramePack ecosystem and ComfyUI.

Developers are free to use the code in this repository.

How to run

$ uv run demo_gradio.py --hf-home ~/.cache/huggingface --lora-dirs ~/my_lora_dir
