Preparation of AVA-Dataset Format for Training on Custom Dataset

Thanks for nice work . I have seen the "demo.gif" which is the output of the model which is trained on the "AVA-Dataset" .Now I want to convert my custom dataset into "AVA-Dataset Format" and want to train a model using your given code . Can you guide me what are pre-processing steps I need to do to convert my own custom dataset into the AVA Dataset Format. Can you give me brief idea or any tools which help me to achieve the "AVA-Dataset Format" . Thanks

I have data set now as follow
```
Dataset/
├── Class-A
│ └── insp.mp4
├── Class-B
│ └── kep.mp4
└── Class-C
└── tak.mp4
```
