## Preparing MSRVTT dataset

For basic dataset information, you can refer to the MSRVTT dataset [website](https://www.microsoft.com/en-us/research/publication/msr-vtt-a-large-video-description-dataset-for-bridging-video-and-language/). Run the following command to prepare the MSRVTT dataset:

```shell
bash prepare_msrvtt.sh
```

After preparation, the folder structure will look like:

```
