Ac3DynamicRangeCompressionLine

Choose the Dolby Digital dynamic range control (DRC) profile that MediaConvert uses when encoding the metadata in the Dolby Digital stream for the line operating mode. Related setting: When you use this setting, MediaConvert ignores any value you provide for Dynamic range compression profile (DynamicRangeCompressionProfile).

Ac3DynamicRangeCompressionProfile

When you want to add Dolby dynamic range compression (DRC) signaling to your output stream, we recommend that you use the mode-specific settings instead of Dynamic range compression profile (DynamicRangeCompressionProfile). The mode-specific settings are Dynamic range compression profile, line mode (dynamicRangeCompressionLine) and Dynamic range compression profile, RF mode (dynamicRangeCompressionRf). Note that when you specify values for all three settings, MediaConvert ignores the value of this setting in favor of the mode-specific settings. If you do use this setting instead of the mode-specific settings, choose None (NONE) to leave out DRC signaling. Keep the default Film standard (FILM_STANDARD) to set the profile to Dolby's film standard profile for all operating modes.

Ac3DynamicRangeCompressionRf

Choose the Dolby Digital dynamic range control (DRC) profile that MediaConvert uses when encoding the metadata in the Dolby Digital stream for the RF operating mode.

dynamicRangeCompressionProfile

When you want to add Dolby dynamic range compression (DRC) signaling to your output stream, we recommend that you use the mode-specific settings instead of Dynamic range compression profile (DynamicRangeCompressionProfile). The mode-specific settings are Dynamic range compression profile, line mode (dynamicRangeCompressionLine) and Dynamic range compression profile, RF mode (dynamicRangeCompressionRf).

sampleRate

This value is always 48000. It represents the sample rate in Hz.

Type: integer Required: False Minimum: 48000 Maximum: 48000

AccelerationMode

Specify whether the service runs your job with accelerated transcoding. Choose DISABLED if you don't want accelerated transcoding. Choose ENABLED if you want your job to run with accelerated transcoding and to fail if your input files or your job settings aren't compatible with accelerated transcoding. Choose PREFERRED if you want your job to run with accelerated transcoding if the job is compatible with the feature and to run at standard speed if it's not.

DISABLED ENABLED PREFERRED

AccelerationSettings

Accelerated transcoding can significantly speed up jobs with long, visually complex content.

mode

Specify the conditions when the service will run your job with accelerated transcoding.

Type: AccelerationMode (p. 125) Required: True

AccelerationStatus

Describes whether the current job is running with accelerated transcoding. For jobs that have

Acceleration (AccelerationMode) set to DISABLED, AccelerationStatus is always NOT_APPLICABLE. For jobs that have Acceleration (AccelerationMode) set to ENABLED or PREFERRED, AccelerationStatus is one of the other states. AccelerationStatus is IN_PROGRESS initially, while the service determines whether the input files and job settings are compatible with accelerated transcoding. If they are,

AcclerationStatus is ACCELERATED. If your input files and job settings aren't compatible with accelerated transcoding, the service either fails your job or runs it without accelerated transcoding, depending on how you set Acceleration (AccelerationMode). When the service runs your job without accelerated transcoding, AccelerationStatus is NOT_ACCELERATED.

AfdSignaling

This setting only applies to H.264, H.265, and MPEG2 outputs. Use Insert AFD signaling (AfdSignaling) to specify whether the service includes AFD values in the output video data and what those values are. * Choose None to remove all AFD values from this output. * Choose Fixed to ignore input AFD values and instead encode the value specified in the job. * Choose Auto to calculate output AFD values based on the input AFD scaler data.
