audioPackingMode
The method of organizing audio channels and tracks. Use Audio:Channels
to specify the number of channels in your output, and Audio:AudioPackingMode
to specify the number of tracks and their relation to the channels. If you do not specify an Audio:AudioPackingMode
, Elastic Transcoder uses SingleTrack
.
The following values are valid:
SingleTrack
, OneChannelPerTrack
, and OneChannelPerTrackWithMosTo8Tracks
When you specify SingleTrack
, Elastic Transcoder creates a single track for your output. The track can have up to eight channels. Use SingleTrack
for all non-mxf
containers.
The outputs of SingleTrack
for a specific channel value and inputs are as follows:
0
** channels with any input:** Audio omitted from the output1, 2, or auto
channels with no audio input: Audio omitted from the output1
channel with any input with audio: One track with one channel, downmixed if necessary2
channels with one track with one channel: One track with two identical channels2 or auto
channels with two tracks with one channel each: One track with two channels2 or auto
channels with one track with two channels: One track with two channels2
channels with one track with multiple channels: One track with two channelsauto
channels with one track with one channel: One track with one channelauto
channels with one track with multiple channels: One track with multiple channels
When you specify OneChannelPerTrack
, Elastic Transcoder creates a new track for every channel in your output. Your output can have up to eight single-channel tracks.
The outputs of OneChannelPerTrack
for a specific channel value and inputs are as follows:
0
channels with any input: Audio omitted from the output1, 2, or auto
channels with no audio input: Audio omitted from the output1
channel with any input with audio: One track with one channel, downmixed if necessary2
channels with one track with one channel: Two tracks with one identical channel each2 or auto
channels with two tracks with one channel each: Two tracks with one channel each2 or auto
channels with one track with two channels: Two tracks with one channel each2
channels with one track with multiple channels: Two tracks with one channel eachauto
channels with one track with one channel: One track with one channelauto
channels with one track with multiple channels: Up to eight tracks with one channel each
When you specify OneChannelPerTrackWithMosTo8Tracks
, Elastic Transcoder creates eight single-channel tracks for your output. All tracks that do not contain audio data from an input channel are MOS, or Mit Out Sound, tracks.
The outputs of OneChannelPerTrackWithMosTo8Tracks
for a specific channel value and inputs are as follows:
0
channels with any input: Audio omitted from the output1, 2, or auto
channels with no audio input: Audio omitted from the output1
channel with any input with audio: One track with one channel, downmixed if necessary, plus six MOS tracks2
channels with one track with one channel: Two tracks with one identical channel each, plus six MOS tracks2 or auto
channels with two tracks with one channel each: Two tracks with one channel each, plus six MOS tracks2 or auto
channels with one track with two channels: Two tracks with one channel each, plus six MOS tracks2
channels with one track with multiple channels: Two tracks with one channel each, plus six MOS tracksauto
channels with one track with one channel: One track with one channel, plus seven MOS tracksauto
channels with one track with multiple channels: Up to eight tracks with one channel each, plus MOS tracks until there are eight tracks in all
