## Aliases

* `&bgblur`

## Options

Example: `&backgroundblur=5`

| Value            | Description                                     |
| ---------------- | ----------------------------------------------- |
| (no value given) | Enables background blur with default amount (2) |
| (integer value)  | Sets the blur amount (0-20)                     |

## Details

`&backgroundblur` is a shortcut for [`&effects=3`](/advanced-settings/video-parameters/effects.md). It enables the ML-based background blur effect on the sender's video.

You can optionally pass a value to set the blur intensity (0-20). For example, `&backgroundblur=5` applies a heavier blur. If no value is given, the default blur amount of 2 is used.

If the user manually adjusts the blur amount via the slider during a session, that value is remembered per room and streamID in localStorage and will be restored on the next visit.
