# CaptionSynchronizationMode

Controls whether MediaLive delays video to synchronize captions with audio and video output.

- Stability: [Experimental](/cdk/api/stability.html)
- Source: [`lib/caption-selector.ts`](https://github.com/aws/aws-cdk/blob/v2.274.0-alpha.0/packages/@aws-cdk/aws-medialive-alpha/lib/caption-selector.ts#L196)

## Example

```ts
// The code below shows an example of how to instantiate this type.
// The values are placeholders you should change.
import * as medialive_alpha from '@aws-cdk/aws-medialive-alpha';
const captionSynchronizationMode = medialive_alpha.CaptionSynchronizationMode.of('value');
```

## Properties

- `NO_VIDEO_DELAY`: [CaptionSynchronizationMode](/cdk/api/v2/docs/@aws-cdk_aws-medialive-alpha.CaptionSynchronizationMode.html) (static) — MediaLive does not delay video for caption alignment.

- `value`: string — The underlying string value passed to CloudFormation.

- `VIDEO_ALIGNED_CAPTIONS`: [CaptionSynchronizationMode](/cdk/api/v2/docs/@aws-cdk_aws-medialive-alpha.CaptionSynchronizationMode.html) (static) — MediaLive delays video to ensure captions are synchronized with audio and video.

## Methods

- `of(value: string): CaptionSynchronizationMode // chainable` (static) — A value not yet modelled by AWS CDK.
