# Video View Customisation

> Video View Customisation — CometChat documentation.

This section will guide you to customise the main video container.

## Implementation

Once you have decided to implement [Default Calling](/sdk/javascript/3.0/calling-default-calling) or [Direct Calling](/sdk/javascript/3.0/calling-direct-calling) calling and followed the steps to implement them. Just few additional methods will help you quickly customize the main video container.

Please make sure your callSettings is configured accordingly for [Default Calling](/sdk/javascript/3.0/calling-default-calling) or [Direct Calling](/sdk/javascript/3.0/calling-direct-calling).

## Main Video Container Setting

The `MainVideoContainerSetting` Class is the required in case you want to customise the main video view. You need to pass the Object of the `MainVideoContainerSetting` Class in the `setMainVideoContainerSetting()` method of the `CallSettingsBuilder`.
