Question: Members,

I am using Vonage API for video calling.

I want to change the video background, Can anyone guide me on this.!

Looking forward to hearing from you!!

Thank you!!

Answer: 
Background replacement and Insertable Streams are on the roadmap in early 2022, but as for now the only thing available to alter the background, using only the Vonage Video API, is the recently released (still in beta) Background Blur method. This is applied to the Publisher via the method [applyVideoFilter](https://tokbox.com/developer/sdks/js/reference/Publisher.html#applyVideoFilter).

Example:

```js
// Start the BG Blur before publishing
OT.initPublisher(someContainer, {
   videoFilter: {
      type: 'backgroundBlur',
   },
})

// Start the BG Blur after publishing
await publisher.applyVideoFilter({
   type: 'backgroundBlur',
   blurStrength: 'low',
})

// Stopping the BG Blur after publishing
await publisher.clearVideoFilter();

```

In the April 2022 announcement:
Added support for filtering video for the publisher. This is a beta feature. Currently, only a background blur filter can be applied. See the `videoFilter` property of the `option` parameter you pass into [OT.initPublisher()](https://tokbox.com/developer/sdks/js/release-notes.html#:%7E:text=you%20pass%20into-,OT.initPublisher(),-method.%20Also%2C%20see) method. Also, see the docs for the [Publisher.applyVideoFilter()](https://tokbox.com/developer/sdks/js/reference/Publisher.html#applyVideoFilter), [Publisher.getVideoFilter()](https://tokbox.com/developer/sdks/js/release-notes.html#:%7E:text=Publisher.getVideoFilter()), and [Publisher.clearVideoFilter()](https://tokbox.com/developer/sdks/js/reference/Publisher.html#clearVideoFilter) methods.

You can read more in the [Vonage Developer Docs](https://tokbox.com/developer/sdks/js/reference/Publisher.html#:%7E:text=applyVideoFilter(videoFilter)).
