Chooses the bitrate (expressed in bps) to encode at in OPUS format.
This property is used only if the EncodeFormats.FormatToUse property is set to ENCODING_FORMAT_OPUS and the EncodeFormats.OPUS.EncodeMode property is set to a value different from OPUS_ENCODE_CUSTOM.
This property is the same as entering either the --bitrate <kbps> setting inside the Appendix E - OpusEnc command line.
For further details about encoding in OPUS format refer to the OPUS object section.
For further information about available encoding formats see the EncodeFormats object.
