# Add subtitle, chapters, and thumbnails to video uploads

[View original](https://ittybit.com/guides/subtitles-chapters-thumbnails)

## Workflow

```json
[
  {
    "kind": "subtitles"
  },
  {
    "kind": "chapters"
  },
  {
    "kind": "thumbnails"
  }
]
```

## Upgrade

Behind-the-scenes, ittybit will upgrade this to extract the data each subtask requires, without you having to do anything.

```json
[
  {
    "kind": "speech",
    "next": [
      {
        "kind": "subtitles"
      }
    ]
  },
  {
    "kind": "outline",
    "next": [
      {
        "kind": "chapters"
      }
    ]
  },
  {
    "kind": "thumbnails",
  }
]
```
