Requirements

The codebase is tested on

• Ubuntu 20.04
• Python 3.10
• PyTorch 2.0.0
• PyTorch Lightning 2.0.2
• 1 NVIDIA GPU (RTX A6000) with CUDA version 11.7. (Other GPUs are also suitable, and 10GB GPU memory is sufficient to run our code.)

To use video visualizer, please install ffmpeg via

sudo apt-get install ffmpeg

For additional Python libraries, please install with

pip install -r requirements.txt

Our code also depends on tiny-cuda-nn. See this repository for Pytorch extension install instructions.

Data

Provided data

We have provided some videos here for quick test. Please download and unzip the data and put them in the root directory. More videos can be downloaded here.

Customize your own data

We segement video sequences using SAM-Track. Once you obtain the mask files, place them in the folder all_sequences/{YOUR_SEQUENCE_NAME}/{YOUR_SEQUENCE_NAME}_masks. Next, execute the following command:

cd data_preprocessing
python preproc_mask.py

We extract optical flows of video sequences using RAFT. To get started, please follow the instructions provided here to download their pretrained model. Once downloaded, place the model in the data_preprocessing/RAFT/models folder. After that, you can execute the following command:

cd data_preprocessing/RAFT
./run_raft.sh

Remember to update the sequence name and root directory in both data_preprocessing/preproc_mask.py and data_preprocessing/RAFT/run_raft.sh accordingly.

After obtaining the files, please organize your own data as follows:

CoDeF
│
└─── all_sequences
    │
    └─── NAME1
           └─ NAME1
           └─ NAME1_masks_0 (optional)
           └─ NAME1_masks_1 (optional)
           └─ NAME1_flow (optional)
           └─ NAME1_flow_confidence (optional)
    │
    └─── NAME2
           └─ NAME2
           └─ NAME2_masks_0 (optional)
           └─ NAME2_masks_1 (optional)
           └─ NAME2_flow (optional)
           └─ NAME2_flow_confidence (optional)
    │
    └─── ...

Pretrained checkpoints

You can download checkpoints pre-trained on the provided videos via

Sequence Name	Config	Download	OpenXLab
beauty_0	configs/beauty_0/base.yaml	Google drive link
beauty_1	configs/beauty_1/base.yaml	Google drive link
white_smoke	configs/white_smoke/base.yaml	Google drive link
lemon_hit	configs/lemon_hit/base.yaml	Google drive link
scene_0	configs/scene_0/base.yaml	Google drive link

And organize files as follows

CoDeF
│
└─── ckpts/all_sequences
    │
    └─── NAME1
        │
        └─── EXP_NAME (base)
            │
            └─── NAME1.ckpt
    │
    └─── NAME2
        │
        └─── EXP_NAME (base)
            │
            └─── NAME2.ckpt
    |
    └─── ...

Train a new model

./scripts/train_multi.sh

where

• GPU: Decide which GPU to train on;
• NAME: Name of the video sequence;
• EXP_NAME: Name of the experiment;
• ROOT_DIRECTORY: Directory of the input video sequence;
• MODEL_SAVE_PATH: Path to save the checkpoints;
• LOG_SAVE_PATH: Path to save the logs;
• MASK_DIRECTORY: Directory of the preprocessed masks (optional);
• FLOW_DIRECTORY: Directory of the preprocessed optical flows (optional);

Please check configuration files in configs/, and you can always add your own model config.

Test reconstruction

./scripts/test_multi.sh

After running the script, the reconstructed videos can be found in results/all_sequences/{NAME}/{EXP_NAME}, along with the canonical image.

Test video translation

After obtaining the canonical image through this step, use your preferred text prompts to transfer it using ControlNet. Once you have the transferred canonical image, place it in all_sequences/${NAME}/${EXP_NAME}_control (i.e. CANONICAL_DIR in scripts/test_canonical.sh).

Then run

./scripts/test_canonical.sh

The transferred results can be seen in results/all_sequences/{NAME}/{EXP_NAME}_transformed.

Note: The canonical_wh option in the configuration file should be set with caution, usually a little larger than img_wh, as it determines the field of view of the canonical image.
