[Paper] [Demo Video]

Requirements

• Python 3.7.13
• torch 1.10.0
• torchvision 0.11.0
• ffmpeg

We conduct the experiments with 4 24G RTX3090 on CUDA 11.1. For more details, please refer to the requirements.txt. We recommend to install pytorch firstly, and then run:

pip install -r requirements.txt

Test

Download the pre-trained models from OneDrive or jianguoyun, and place them to the folder test/checkpoints . Then run the following command:

CUDA_VISIBLE_DEVICES=0 python inference_single.py

To inference on other videos, please specify the --input and --audio option and see more details in code.

The evaluation code is similar to this repo.

Train

download LRS2 dataset

Our models are trained on LRS2. Please go to the LRS2 website to download the dataset. LRS2 dataset folder structure is following:

data_root (mvlrs_v1)
├── main, pretrain (we use only main folder in this work)
|	├── list of folders
|	│   ├── five-digit numbered video IDs ending with (.mp4)

main folder is the lrs2_video mentioned below.

preprocess the audio

extract the raw audio and Mel-spectrum feature from video files by running:

CUDA_VISIBLE_DEVICES=0 python preprocess_audio.py --data_root ....../lrs2_video/ --out_root ..../lrs2_audio

preprocess the videos' face

extract the cropped face, landmarks and sketches from video files by running:

CUDA_VISIBLE_DEVICES=0 python preprocess_video.py --dataset_video_root ....../lrs2_video/ --output_sketch_root ..../lrs2_sketch --output_face_root ..../lrs2_face --output_landmark_root ..../lrs2_landmarks

train Landmark generator

train the landmark generator network by running:

CUDA_VISIBLE_DEVICES=0 python train_landmarks_generator.py --pre_audio_root ..../lrs2_audio --landmarks_root ..../lrs2_landmarks

The models are trained until the eval_L1_loss no longer decreases (about 6e-3). Under the default batchsize setting on a single RTX 3090, our model stopped at epoch 1837(610k iteration) with eval_L1_loss 5.866 e-3, using no more than one day.

train Video Renderer

Training for the video renderer is similar (on four RTX 3090). Train it until the FID no longer decreases (about 20 or less). train the video renderer network by running:

CUDA_VISIBLE_DEVICES=0,1,2,3 python train_video_renderer.py --sketch_root ..../lrs2_sketch --face_img_root ..../lrs2_face  --audio_root ..../lrs2_audio

Note that the translation module will only be trained after 25 epochs, thus the fid and running_gen_loss will only decrease after epoch 25.
