FancyVideo: Towards Dynamic and Consistent Video Generation via Cross-frame Textual Guidance

Jiasong Feng*, Ao Ma*†, Jing Wang*, Bo Cheng, Xiaodan Liang, Dawei Leng‡, Yuhui Yin(*Equal Contribution, †Project Lead, ‡Corresponding Authors)

Our code builds upon AnimateDiff, and we also incorporate insights from CV-VAE, Res-Adapter, and Long-CLIP to enhance our project. We appreciate the open-source contributions of these works.

🔥 News

• [2024/10/10] 🔥 We released the 125-frame model, along with the video extending model and the video backtracking model, all developed from the 61-frame model. The model has been uploaded to huggingface.
• [2024/09/05] We are thrilled to present our latest research: Qihoo-T2X, a pioneering DiT architecture paradigm designed for Text-to-Any tasks.
• [2024/08/19] We initialized this github repository and released the inference code and 61-frame model.
• [2024/08/15] We released the paper of FancyVideo.

🕓 Schedules

• [In early October 2024] We plan to release the 125-frame model of FancyVideo, along with the video extending model and the video backtracking model. [√]
• [In early November 2024] We plan to release the training code of FancyVideo.
• [Temporary uncertainty] We plan to release the 16-channel 3D Video VAEs and corresponding model of FancyVideo.

Quick Demos

Video demos can be found in the webpage. Some of them are contributed by the community. You can customize your own videos using the following reasoning code.

Quick Start

0. Experimental environment

We tested our inference code on a machine with a 24GB 3090 GPU and CUDA environment version 12.1.

1. Setup repository and environment

git clone https://github.com/360CVGroup/FancyVideo.git
cd FancyVideo

conda create -n fancyvideo python=3.10
conda activate fancyvideo
pip install -r requirements.txt

2. Prepare the models

# fancyvideo-ckpts & cv-vae & res-adapter & longclip & sdv1.5-base-models
git lfs install
git clone https://huggingface.co/qihoo360/FancyVideo
mv FancyVideo/resources/models resources 


# stable-diffusion-v1-5
git clone https://huggingface.co/runwayml/stable-diffusion-v1-5 resources/models

After download models, your resources folder is like:

📦 resources/
├── 📂 models/
│   └── 📂 fancyvideo_ckpts/
│       └── 📂 vae_3d_61_frames/
│       └── 📂 vae_3d_125_frames/
│       └── 📂 video_extending/
│       └── 📂 video_backtracking/
│   └── 📂 CV-VAE/
│   └── 📂 res-adapter/
│   └── 📂 LongCLIP-L/
│   └── 📂 sd_v1-5_base_models/
│   └── 📂 stable-diffusion-v1-5/
├── 📂 demos/
│   └── 📂 reference_images/
│   └── 📂 reference_videos/
│   └── 📂 test_prompts/

3. Customize your own videos

3.1 Image to Video

Due to the limited image generation capabilities of the SD1.5 model, we recommend generating the initial frame using a more advanced T2I model, such as SDXL, and then using our model's I2V capabilities to create the video.

CUDA_VISIBLE_DEVICES=0 PYTHONPATH=./ python scripts/demo.py --config configs/inference/i2v.yaml

3.2 Text to Video with different base models

Our model features universal T2V capabilities and can be customized with the SD1.5 community base model.

# use the base model of pixars
CUDA_VISIBLE_DEVICES=0 PYTHONPATH=./ python scripts/demo.py --config configs/inference/t2v_pixars.yaml

# use the base model of realcartoon3d
CUDA_VISIBLE_DEVICES=0 PYTHONPATH=./ python scripts/demo.py --config configs/inference/t2v_realcartoon3d.yaml

# use the base model of toonyou
CUDA_VISIBLE_DEVICES=0 PYTHONPATH=./ python scripts/demo.py --config configs/inference/t2v_toonyou.yaml

3.3 Image to Video with 125-Frame Model

Similar to 3.1, section 3.2 can also utilize this model.

CUDA_VISIBLE_DEVICES=0 PYTHONPATH=./ python scripts/demo.py --config configs/inference/i2v_125_frames.yaml

3.4 Video Extending

You can expand your 61 frames of video to 125 frames by increasing the latent space from 16 to 32.

CUDA_VISIBLE_DEVICES=0 PYTHONPATH=./ python scripts/demo.py --config configs/inference/video_extending.yaml

3.5 Video Backtracking

You can downscale your 61 frames of video to 125 frames by adjusting the latent space from 16 to 32.

CUDA_VISIBLE_DEVICES=0 PYTHONPATH=./ python scripts/demo.py --config configs/inference/video_backtracking.yaml
