# TimecodeConfig

Timecode configuration for the channel.

- Stability: [Experimental](/cdk/api/stability.html)
- Source: [`lib/channel.ts`](https://github.com/aws/aws-cdk/blob/v2.275.0-alpha.0/packages/@aws-cdk/aws-medialive-alpha/lib/channel.ts#L317)

## Example

```ts
declare const stack: Stack;
declare const input: medialive.IInput;
declare const bucket: s3.IBucket;
declare const video: medialive.EncodeConfiguration;
declare const audio: medialive.EncodeConfiguration;

new medialive.Channel(stack, 'Channel', {
  inputs: [{ input }],
  timecodeConfig: {
    source: medialive.TimecodeSource.EMBEDDED,
  },
  globalConfiguration: {
    outputLocking: medialive.OutputLocking.epoch(),
    outputTimingSource: medialive.OutputTimingSource.INPUT_CLOCK,
  },
  outputGroups: [
    medialive.OutputGroupConfiguration.hls({
      name: 'hls',
      destinations: [medialive.OutputDestination.toBucket(bucket, 'live/stream')],
      outputs: [{ encodes: [video, audio], outputName: 'hls_out' }],
    }),
  ],
});
```

## Properties

- `source`: [TimecodeSource](/cdk/api/v2/docs/@aws-cdk_aws-medialive-alpha.TimecodeSource.html) = TimecodeSource.EMBEDDED — The source of timecode.

- `syncThreshold`: number — The threshold in frames beyond which output timecode is resynchronized to the input timecode.

  **Default:** no sync threshold
