Specify this setting only when your output will be consumed by a downstream repackaging workflow that is
sensitive to very small duration differences between video and audio. For this situation, choose Match video
duration. In all other cases, keep the default value, Default codec duration. When you choose Match video
duration, MediaConvert pads the output audio streams with silence or trims them to ensure that the total duration
of each audio stream is at least as long as the total duration of the video stream. After padding or trimming, the
audio stream duration is no more than one frame longer than the video stream. MediaConvert applies audio padding
or trimming only to the end of the last segment of the output. For unsegmented outputs, MediaConvert adds padding
only to the end of the file. When you keep the default value, any minor discrepancies between audio and video
duration will depend on your output audio codec.
