Bitrate
-
The average bitrate in bits/second. Valid bitrates depend on the coding mode.
Required: No
Type: Number
Update requires: No interruption
BitstreamMode
-
Specifies the bitstream mode (bsmod) for the emitted AC-3 stream. For more information about these values, see ATSC A/52-2012.
Required: No
Type: String
Update requires: No interruption
CodingMode
-
The Dolby Digital coding mode. This determines the number of channels.
Required: No
Type: String
Update requires: No interruption
Dialnorm
-
Sets the dialnorm for the output. If excluded and the input audio is Dolby Digital, dialnorm is passed through.
Required: No
Type: Integer
Update requires: No interruption
DrcProfile
-
If set to filmStandard, adds dynamic range compression signaling to the output bitstream as defined in the Dolby Digital specification.
Required: No
Type: String
Update requires: No interruption
LfeFilter
-
When set to enabled, applies a 120Hz lowpass filter to the LFE channel prior to encoding. This is valid only in codingMode32Lfe mode.
Required: No
Type: String
Update requires: No interruption
MetadataControl
-
When set to followInput, encoder metadata is sourced from the DD, DD+, or DolbyE decoder that supplies this audio data. If the audio is supplied from one of these streams, the static metadata settings are used.
