+### 🛠️ Prepare Inference Data
+
+Hallo has a few simple requirements for input data:
+
+For the source image:
+
+1. It should be cropped into squares.
+2. The face should be the main focus, making up 50%-70% of the image.
+3. The face should be facing forward, with a rotation angle of less than 30° (no side profiles).
+
+For the driving audio:
+
+1. It must be in WAV format.
+2. It must be in English since our training datasets are only in this language.
+3. Ensure the vocals are clear; background music is acceptable.
+
+We have provided [some samples](examples/) for your reference.
+
+### 🎮 Run Inference
+
+#### Long-Duration animation
+
+Simply to run the `scripts/inference_long.py` and change `source_image`, `driving_audio` and `save_path` in the config file:
+
+```bash
+python scripts/inference_long.py --config ./configs/inference/long.yaml
+```
+
+Animation results will be saved at `save_path`. You can find more examples for inference at [examples folder](https://github.com/fudan-generative-vision/hallo2/tree/main/examples).
+
+For more options:
+
+```shell
+usage: inference_long.py [-h] [-c CONFIG] [--source_image SOURCE_IMAGE] [--driving_audio DRIVING_AUDIO] [--pose_weight POSE_WEIGHT]

+
+## Training
+
+### Long-Duration animation
+
+#### prepare data for training
+
+The training data, which utilizes some talking-face videos similar to the source images used for inference, also needs to meet the following requirements:
+
+1. It should be cropped into squares.
+2. The face should be the main focus, making up 50%-70% of the image.
+3. The face should be facing forward, with a rotation angle of less than 30° (no side profiles).
+
+Organize your raw videos into the following directory structure:
+
+```text
+dataset_name/
+|-- videos/
+| |-- 0001.mp4
+| |-- 0002.mp4
+| |-- 0003.mp4
+| `-- 0004.mp4
+```
+
+You can use any `dataset_name`, but ensure the `videos` directory is named as shown above.
+
+Next, process the videos with the following commands:
+
+```bash
+python -m scripts.data_preprocess --input_dir dataset_name/videos --step 1
+python -m scripts.data_preprocess --input_dir dataset_name/videos --step 2
+```
+
+**Note:** Execute steps 1 and 2 sequentially as they perform different tasks. Step 1 converts videos into frames, extracts audio from each video, and generates the necessary masks. Step 2 generates face embeddings using InsightFace and audio embeddings using Wav2Vec, and requires a GPU. For parallel processing, use the `-p` and `-r` arguments. The `-p` argument specifies the total number of instances to launch, dividing the data into `p` parts. The `-r` argument specifies which part the current process should handle. You need to manually launch multiple instances with different values for `-r`.
+
+Generate the metadata JSON files with the following commands:
+
+```bash
+python scripts/extract_meta_info_stage1.py -r path/to/dataset -n dataset_name
+python scripts/extract_meta_info_stage2.py -r path/to/dataset -n dataset_name
+```
+
+Replace `path/to/dataset` with the path to the parent directory of `videos`, such as `dataset_name` in the example above. This will generate `dataset_name_stage1.json` and `dataset_name_stage2.json` in the `./data` directory.
+
+#### Training
+
+Update the data meta path settings in the configuration YAML files, `configs/train/stage1.yaml` and `configs/train/stage2_long.yaml`:
+
+```yaml
+#stage1.yaml
+data:
+ meta_paths:
+ - ./data/dataset_name_stage1.json
+
+#stage2.yaml
+data:
+ meta_paths:
+ - ./data/dataset_name_stage2.json
+```
+
+Start training with the following command:
+
+```shell
+accelerate launch -m \
+ --config_file accelerate_config.yaml \
+ --machine_rank 0 \
+ --main_process_ip 0.0.0.0 \
+ --main_process_port 20055 \
+ --num_machines 1 \
+ --num_processes 8 \
+ scripts.train_stage1 --config ./configs/train/stage1.yaml
+```
+
+##### Accelerate Usage Explanation
+
+The `accelerate launch` command is used to start the training process with distributed settings.
+
+```shell
+accelerate launch [arguments] {training_script} --{training_script-argument-1} --{training_script-argument-2} ...
+```
+
+**Arguments for Accelerate:**
+
+- `-m, --module`: Interpret the launch script as a Python module.
+- `--config_file`: Configuration file for Hugging Face Accelerate.
+- `--machine_rank`: Rank of the current machine in a multi-node setup.
+- `--main_process_ip`: IP address of the master node.
+- `--main_process_port`: Port of the master node.
+- `--num_machines`: Total number of nodes participating in the training.
+- `--num_processes`: Total number of processes for training, matching the total number of GPUs across all machines.
+
+**Arguments for Training:**
+
+- `{training_script}`: The training script, such as `scripts.train_stage1` or `scripts.train_stage2`.
+- `--{training_script-argument-1}`: Arguments specific to the training script. Our training scripts accept one argument, `--config`, to specify the training configuration file.
+
+For multi-node training, you need to manually run the command with different `machine_rank` on each node separately.
+
+For more settings, refer to the [Accelerate documentation](https://huggingface.co/docs/accelerate/en/index).
+
+### High-Resolution animation
+
+#### Training
+
+##### prepare data for training
+
+We use the VFHQ dataset for training, you can download from its [homepage](https://liangbinxie.github.io/projects/vfhq/). Then updata `dataroot_gt` in `./configs/train/video_sr.yaml`.
+
+#### training
+
+Start training with the following command:
+
+```shell
+python -m torch.distributed.launch --nproc_per_node=8 --master_port=4322 \
+basicsr/train.py -opt ./configs/train/video_sr.yaml \
+--launcher pytorch
+```

+
+## ⚠️ Social Risks and Mitigations
+
+The development of portrait image animation technologies driven by audio inputs poses social risks, such as the ethical implications of creating realistic portraits that could be misused for deepfakes. To mitigate these risks, it is crucial to establish ethical guidelines and responsible use practices. Privacy and consent concerns also arise from using individuals' images and voices. Addressing these involves transparent data usage policies, informed consent, and safeguarding privacy rights. By addressing these risks and implementing mitigations, the research aims to ensure the responsible and ethical development of this technology.
