Multiple Audio Input/Output streams

  • Issue

    If the source files contain more than 1 video and 1 audio stream (e.g. an MP4 source file with 1 video and 2 audio) then Voukoder 10.2 with Premiere Connector 1.10.0 cannot be used to render that file to a proxy clip (lower quality/resolution copy of the source file).

    The selected preset does not support the audio channel type of the clip #1.mp4

    Example of unsupported input stream configuration:

    Suggestion

    Currently, Adobe Media Encoder 22.2–and Adobe Premiere Pro 22.0.0 by extension–only supports outputting multiple audio streams to the QuickTime container format.


    When exporting to the QuickTime format, the Audio settings tab has a section titled "Audio Channel Configuration". (Image 1)

    "Stream" entries are incremented with the "+" button and decremented with the "-" button.

    "Output Channels" dropdown (Image 2) provides the following configurations. FFMpeg could provide similar or vastly different options depending on the audio format and codec. Because Adobe Media Encoder does not provide a "match source" example for audio channels and streams, it may be difficult to implement the ability to pass source audio streams to Voukoder as-is.

    "Source Channels" is inferred from the "Stream" and "Output Channels" settings.

    "Channel Layout" can be configured when more there are multiple streams.

    Afterword

    Normally, one would request this feature to be implemented by Adobe for all applicable container formats, but I get the feeling that they're contractually obligated to not do so.

    Approved the thread.
  • I would love for Vegas Pro to be able to output a single render which Voukoder would simultaneously encode into multiple output formats using hardware NVENC. In my specific case, I would be encoding a 1080p24 Vegas output into AVC (video only), h.265 (video and audio), and AC3 (audio only).
