Metadata provides technical and contextual information about each video uploaded to the platform. By default, all the videos have the following metadata associated with them:

duration: The duration of the video, expressed in seconds
filename: The filename
fps: The number of frames per second
height: The height of the video
size: The size of the video file, expressed in KB
video_title: The title of the video (defaults to the file name)
width: The width of the video

Custom metadata is the ability to add more data to your videos. For example, you can add the following fields: channel, views, downloads, country of origin, language, and URL. This allows you to provide more detailed, specialized, or context-specific information.

Note the following about adding custom metadata to your videos:

You cannot override any of the predefined metadata
The values you provide must be of the following types: string, integer, float or boolean. If you want to store other types of data such as objects or arrays, you must convert your data into string values.

Prerequisites

You’re familiar with the concepts that are described on the Platform overview page.
You’ve created at least one index, and the unique identifier of your index is stored in a variable named INDEX_ID. For details, see the Create indexespage.
You've uploaded a video, and the platform has finished indexing it. The unique identifier of your video is stored in a variable named VIDEO_ID. For details about uploading videos, see the Upload videos page.

Procedure

Construct the URL for providing custom video metadata based on the API_URL, INDEX_ID, and VIDEO_ID variables:

VIDEOS_URL = f"{API_URL}/indexes/{INDEX_ID}/videos/{VIDEO_ID}"

const VIDEOS_URL = `${API_URL}/indexes/${INDEX_ID}/videos/${VIDEO_ID}`

Create the request body. You must provide your custom metadata using a dictionary named metadata. In the example code below, the metadata dictionary has four keys: views, downloads, language and country. The views and downloads keys are integers, and thecreation_date and country keys are strings:
```
data = {
    "metadata": {
        "views": 12000,
        "downloads": 40000,
        "language": "en-us",
        "country": "USA"
    }
}
```
```
const data = {
  'metadata': {
    'views': 12000,
    'downloads': 40000,
    'language': 'en-us',
    'country': 'USA'
  }
```

To set your custom metadata, call the PUT method of the /indexes/{index-id}/videos/{video-id endpoint:

response = requests.put(VIDEOS_URL, headers=headers, json=data)

const config = {
  method: 'put',
  url: VIDEOS_URL,
  headers: headers,
  data : data 
}
const response = await axios(config)

If successful, this method does not return anything in the response body. The example code below prints the status code:
```
print (f"Status code: {response.status_code}")
```
```
console.log(`Status code: ${response.status}`)
```
The output should look similar to the following one:
```
Status code: 200
```

Next Steps

Once you've added custom metadata to your videos, you can use it to filter the results returned by the /indexes/videos and /search endpoints.
