 **Input** | [**[]InputSettings**](InputSettings.md) | An array of objects that each describe an input file to be used to create the asset. As a shortcut, input can also be a string URL for a file when only one input file is used. See `input[].url` for requirements. | [optional] 
-**PlaybackPolicy** | [**[]PlaybackPolicy**](PlaybackPolicy.md) | An array of playback policy names that you want applied to this asset and available through `playback_ids`. Options include: `\"public\"` (anyone with the playback URL can stream the asset). And `\"signed\"` (an additional access token is required to play the asset). If no playback_policy is set, the asset will have no playback IDs and will therefore not be playable. For simplicity, a single string name can be used in place of the array in the case of only one playback policy. | [optional]

 **PerTitleEncode** | **bool** |  | [optional] 
 **Passthrough** | **string** | Arbitrary user-supplied metadata that will be included in the asset details and related webhooks. Can be used to store your own ID for a video along with the asset. **Max: 255 characters**. | [optional] 
 **Mp4Support** | **string** | Specify what level of support for mp4 playback.  * The `capped-1080p` option produces a single MP4 file, called `capped-1080p.mp4`, with the video resolution capped at 1080p. This option produces an `audio.m4a` file for an audio-only asset. * The `audio-only` option produces a single M4A file, called `audio.m4a` for a video or an audio-only asset. MP4 generation will error when this option is specified for a video-only asset. * The `audio-only,capped-1080p` option produces both the `audio.m4a` and `capped-1080p.mp4` files. Only the `capped-1080p.mp4` file is produced for a video-only asset, while only the `audio.m4a` file is produced for an audio-only asset.  The `standard`(deprecated) option produces up to three MP4 files with different levels of resolution (`high.mp4`, `medium.mp4`, `low.mp4`, or `audio.m4a` for an audio-only asset).  MP4 files are not produced for `none` (default).  In most cases you should use our default HLS-based streaming playback (`{playback_id}.m3u8`) which can automatically adjust to viewers' connection speeds, but an mp4 can be useful for some legacy devices or downloading for offline playback. See the [Download your videos guide](https://docs.mux.com/guides/enable-static-mp4-renditions) for more information.  | [optional]

 **NewAssetSettings** | [**CreateAssetRequest**](CreateAssetRequest.md) |  | [optional] 
 **ReconnectWindow** | **float32** | When live streaming software disconnects from Mux, either intentionally or due to a drop in the network, the Reconnect Window is the time in seconds that Mux should wait for the streaming software to reconnect before considering the live stream finished and completing the recorded asset. Defaults to 60 seconds on the API if not specified.  If not specified directly, Standard Latency streams have a Reconnect Window of 60 seconds; Reduced and Low Latency streams have a default of 0 seconds, or no Reconnect Window. For that reason, we suggest specifying a value other than zero for Reduced and Low Latency streams.  Reduced and Low Latency streams with a Reconnect Window greater than zero will insert slate media into the recorded asset while waiting for the streaming software to reconnect or when there are brief interruptions in the live stream media. When using a Reconnect Window setting higher than 60 seconds with a Standard Latency stream, we highly recommend enabling slate with the `use_slate_for_standard_latency` option.  | [optional] [default to 60]
 **UseSlateForStandardLatency** | **bool** | By default, Standard Latency live streams do not have slate media inserted while waiting for live streaming software to reconnect to Mux. Setting this to true enables slate insertion on a Standard Latency stream. | [optional] [default to false]

This option produces an `audio.m4a` file for an audio-only asset. * The `audio-only` option produces a single M4A file, called `audio.m4a` for a video or an audio-only asset. MP4 generation will error when this option is specified for a video-only asset. * The `audio-only,capped-1080p` option produces both the `audio.m4a` and `capped-1080p.mp4` files. Only the `capped-1080p.mp4` file is produced for a video-only asset, while only the `audio.m4a` file is produced for an audio-only asset.  The `standard`(deprecated) option produces up to three MP4 files with different levels of resolution (`high.mp4`, `medium.mp4`, `low.mp4`, or `audio.m4a` for an audio-only asset).  MP4 files are not produced for `none` (default).  In most cases you should use our default HLS-based streaming playback (`{playback_id}.m3u8`) which can automatically adjust to viewers' connection speeds, but an mp4 can be useful for some legacy devices or downloading for offline playback. See the [Download your videos guide](https://docs.mux.com/guides/enable-static-mp4-renditions) for more information.

Defaults to 60 seconds on the API if not specified.  If not specified directly, Standard Latency streams have a Reconnect Window of 60 seconds; Reduced and Low Latency streams have a default of 0 seconds, or no Reconnect Window. For that reason, we suggest specifying a value other than zero for Reduced and Low Latency streams.  Reduced and Low Latency streams with a Reconnect Window greater than zero will insert slate media into the recorded asset while waiting for the streaming software to reconnect or when there are brief interruptions in the live stream media. When using a Reconnect Window setting higher than 60 seconds with a Standard Latency stream, we highly recommend enabling slate with the `use_slate_for_standard_latency` option.
