# Boost Mode

Boost gives everyone in the room a sharper video picture with one switch. Turn it on when picture quality matters most, and off when you'd rather keep things lighter.

Boost applies to the whole room, not to individual participants. You can set it ahead of time from the homepage, or switch it on or off at any point during a call.

## **What Boost changes**

Boost switches the room between two video quality levels.

| **Boost** | **What participants see** |
| :- | :- |
| **On** | High-quality, sharper video |
| **Off** | Standard-quality video that uses less bandwidth |

* **It's saved with the room.** Your choice is still there the next time you open the room.

> [!WARNING]
>
> **Higher quality uses more bandwidth.** Participants on slower connections may notice the difference when Boost is on.

> [!NOTE]
>
> **Boost only applies to participants' video.** Presentations (screen share, whiteboard) and video presented in the room, such as media and streaming, are not affected.

## **Who can use Boost**

Boost is a Room Control, so it follows the same access rules as the other settings in that group.

* **Host and co-host** can turn Boost on or off.
* **Participants** cannot change it, but they receive the room's video quality.

## **How to turn Boost on or off**

Boost is found in the Side Panel, under Settings → Room Controls. It's the same control whether you're on the homepage or inside a call.

**1. Open the **Side Panel** and go to the **Settings** tab.**

**2. Expand **Room Controls**.**

**3. Switch **Boost** on or off.**

> [!TIP]
>
> **During a call, the change applies to the whole room.** There's no need for participants to do anything.

## **Boost and participant tiles**

With Boost on, participant tiles can be displayed larger without looking blurry.

Boost also affects the aspect ratio setting in [Tile Settings](https://help.coresee.com/help/control-panel/tile-settings.md)  (Appearance tab):

* **Boost on:** you can choose the tile aspect ratio.
* **Boost off:** the aspect ratio setting is blocked and tiles use the default 16:9.

## **When to use Boost**

> [card] ISO recording
>
> *Turn Boost ON*
>
> Boost is important for ISO recording. Turn it on before you record so each participant's individual feed is captured in high quality.

> [card] Demos, panels and productions
>
> *Turn Boost ON*
>
> When viewers need to see people clearly, or you're streaming or recording the room, turn Boost on for a sharper participant picture. Presentations and presented video aren't affected by Boost.

> [card] Large meetings or mixed connections
>
> *Turn Boost OFF*
>
> When many people are on the call or some have weaker connections, the lower setting keeps video lighter on bandwidth.
