🎏 Abstract

TL; DR: FateZero is the first zero-shot framework for text-driven video editing via pretrained diffusion models without training.

The diffusion-based generative models have achieved remarkable success in text-based image generation. However, since it contains enormous randomness in generation progress, it is still challenging to apply such models for real-world visual content editing, especially in videos. In this paper, we propose FateZero, a zero-shot text-based editing method on real-world videos without per-prompt training or use-specific mask. To edit videos consistently, we propose several techniques based on the pre-trained models. Firstly, in contrast to the straightforward DDIM inversion technique, our approach captures intermediate attention maps during inversion, which effectively retain both structural and motion information. These maps are directly fused in the editing process rather than generated during denoising. To further minimize semantic leakage of the source video, we then fuse self-attentions with a blending mask obtained by cross-attention features from the source prompt. Furthermore, we have implemented a reform of the self-attention mechanism in denoising UNet by introducing spatial-temporal attention to ensure frame consistency. Yet succinct, our method is the first one to show the ability of zero-shot text-driven video style and local attribute editing from the trained text-to-image model. We also have a better zero-shot shape-aware editing ability based on the text-to-video model. Extensive experiments demonstrate our superior temporal consistency and editing capability than previous works.

🛡 Setup Environment

Our method is tested using cuda11, fp16 of accelerator and xformers on a single A100 or 3090.

conda create -n fatezero38 python=3.8
conda activate fatezero38

pip install -r requirements.txt

xformers is recommended for A100 GPU to save memory and running time.

Click for xformers installation

We find its installation not stable. You may try the following wheel:

wget https://github.com/ShivamShrirao/xformers-wheels/releases/download/4c06c79/xformers-0.0.15.dev0+4c06c79.d20221201-cp38-cp38-linux_x86_64.whl
pip install xformers-0.0.15.dev0+4c06c79.d20221201-cp38-cp38-linux_x86_64.whl

Validate the installation by

python test_install.py

You may download all data and checkpoints using the following bash command

bash download_all.sh

The above command take minutes and 100GB. Or you may download the required data and ckpts latter according to your interests.

Our environment is similar to Tune-A-video (official, unofficial) and prompt-to-prompt. You may check them for more details.

⚔️ FateZero Editing

Style and Attribute Editing in Teaser

Download the stable diffusion v1-4 (or other interesting image diffusion model) and put it to ./ckpt/stable-diffusion-v1-4.

Click for the bash command:

mkdir ./ckpt
cd ./ckpt
# download from huggingface face, takes 20G space
git lfs install
git clone https://huggingface.co/CompVis/stable-diffusion-v1-4

Then, you could reproduce style and shape editing results in our teaser by running:

accelerate launch test_fatezero.py --config config/teaser/jeep_watercolor.yaml
# or CUDA_VISIBLE_DEVICES=0 python test_fatezero.py --config config/teaser/jeep_watercolor.yaml

The result is saved at `./result` . (Click for directory structure)

Editing 8 frames on an Nvidia 3090, use 100G CPU memory, 12G GPU memory for editing. We also provide some low-cost setting of style editing by different hyper-parameters on a 16GB GPU. You may try these low-cost settings on colab.

More speed and hardware benchmarks are here.

Shape and large motion editing with Tune-A-Video

Besides style and attribution editing above, we also provide a Tune-A-Video checkpoint. You may download from onedrive or from hugging face model repository. Then move it to ./ckpt/jeep_tuned_200/.

Click for the bash command:

mkdir ./ckpt
cd ./ckpt
# download from huggingface face, takes 10G space
git lfs install
git clone https://huggingface.co/chenyangqi/jeep_tuned_200

The directory structure should be like this: (Click for directory structure)

You could reproduce the shape editing result in our teaser by running:

accelerate launch test_fatezero.py --config config/teaser/jeep_posche.yaml

Reproduce other results in the paper

Download the data from onedrive or from Github Release.

Click for wget bash command:

wget https://github.com/ChenyangQiQi/FateZero/releases/download/v0.0.1/attribute.zip
wget https://github.com/ChenyangQiQi/FateZero/releases/download/v0.0.1/style.zip
wget https://github.com/ChenyangQiQi/FateZero/releases/download/v0.0.1/shape.zip

Unzip and Place it in './data'. Then use the commands in 'config/style' and 'config/attribute' to get the results.

To reproduce other shape editing results, download Tune-A-Video checkpoints from huggingface :

Click for the bash command:

mkdir ./ckpt
cd ./ckpt
# download from huggingface face, takes 10G space
git lfs install
git clone https://huggingface.co/chenyangqi/man_skate_250
git clone https://huggingface.co/chenyangqi/swan_150

Then use the commands in 'config/shape'.

For above Tune-A-Video checkpoints, we fintune stable diffusion with a synthetic negative-prompt dataset for regularization and low-rank conovlution for temporal-consistent generation using tuning config

Click for the bash command example:

cd ./data
wget https://github.com/ChenyangQiQi/FateZero/releases/download/v0.0.1/negative_reg.zip
unzip negative_reg
cd ..
accelerate launch train_tune_a_video.py --config config/tune/jeep.yaml
