🔆 Introduction

🔥🔥 Generative frame interpolation / looping video generation model weights (320x512) have been released!

🔥 New Update Rolls Out for DynamiCrafter! Better Dynamic, Higher Resolution, and Stronger Coherence!
🤗 DynamiCrafter can animate open-domain still images based on text prompt by leveraging the pre-trained video diffusion priors. Please check our project page and paper for more information.
😀 We will continue to improve the model's performance.

🧰 Models

Model	Resolution	GPU Mem. & Inference Time (A100, ddim 50steps)	Checkpoint
DynamiCrafter1024	576x1024	18.3GB & 75s (perframe_ae=True)	Hugging Face
DynamiCrafter512	320x512	12.8GB & 20s (perframe_ae=True)	Hugging Face
DynamiCrafter256	256x256	11.9GB & 10s (perframe_ae=False)	Hugging Face
DynamiCrafter512_interp	320x512	12.8GB & 20s (perframe_ae=True)	Hugging Face

Currently, our DynamiCrafter can support generating videos of up to 16 frames with a resolution of 576x1024. The inference time can be reduced by using fewer DDIM steps.

GPU memory consumed on RTX 4090 reported by @noguchis in Twitter: 18.3GB (576x1024), 12.8GB (320x512), 11.9GB (256x256).

⚙️ Setup

Install Environment via Anaconda (Recommended)

conda create -n dynamicrafter python=3.8.5
conda activate dynamicrafter
pip install -r requirements.txt

💫 Inference

1. Command line

Image-to-Video Generation

1. Download pretrained models via Hugging Face, and put the model.ckpt with the required resolution in checkpoints/dynamicrafter_[1024|512|256]_v1/model.ckpt.
2. Run the commands based on your devices and needs in terminal.

  # Run on a single GPU:
  # Select the model based on required resolutions: i.e., 1024|512|320:
  sh scripts/run.sh 1024
  # Run on multiple GPUs for parallel inference:
  sh scripts/run_mp.sh 1024

Generative Frame Interpolation / Looping Video Generation

Download pretrained model DynamiCrafter512_interp and put the model.ckpt in checkpoints/dynamicrafter_512_interp_v1/model.ckpt.

  sh scripts/run_application.sh interp # Generate frame interpolation
  sh scripts/run_application.sh loop   # Looping video generation

2. Local Gradio demo

Image-to-Video Generation

1. Download the pretrained models and put them in the corresponding directory according to the previous guidelines.
2. Input the following commands in terminal (choose a model based on the required resolution: 1024, 512 or 256).

  python gradio_app.py --res 1024

Generative Frame Interpolation / Looping Video Generation

Download the pretrained model and put it in the corresponding directory according to the previous guidelines.
