## TODO
- [ ] Gradio Demo
- [ ] Huggingface setup
- [x] Release training-free DMC module
- [ ] Release training code
- [x] Release inference code

## Directional Control

### Environmental Setup

``bash environment.bash
``

### Inference
Download the checkpoint from [Google Drive](https://drive.google.com/file/d/1cydrG4xXchUfGLWAeB-uRf2u7EWgVN_c/view?usp=sharing) and put it under the root path of this folder.

Write your text prompt in prompts.txt.

Run the inference by:
```bash
bash configs/inference/run_text2video.sh
```

To achieve the directional/trajectory guidance, you need to specify the object name and it's spatial locations by (the object name should be in your text prompt):

```bash
--object_phrase # The object name to control the moving direction/trajectory in the generated video.

--bboxes # The location of input bounding boxes
```

You can also specify the number of guidance steps by:

```bash
--guidance_step # The number of steps to performance guidance, the higher the stronger guidance.
```

and guidance scale directly by:
```bash
--loss_scale # The higher scale, the stronger guidance.
```

## News
* `2025.6.10`  Release the inference code of DMC.
* `2025.2.10`  🚀 Release the [project website](https://sites.google.com/view/mojito-video)!
