  XDCAM HD 422 video with MPEG 1 Layer 2 audio?

  Posted by Brittany Barnes on January 20, 2015 at 8:15 pm

  I’ve been researching for a few hours now to export to these video and audio specs through Compressor on behalf of a client in Thailand, and have hit a roadblock.

  Here are the specs they sent us:

  Codec: XDCAM HD 422
  Resolution: 1920x1080i
  FPS: 25 PAL
  Video Bitrate: 50 (cbr)
  Scan: Interlaced

  Audio Codec: MPEG 1 Layer 2
  Track: 8
  Bit Depth 24
  Bitrate: 384
  Audio Sample Rate: 48

  Video can be MOV, MPEG or MXF.

  The video aspect was super easy to accomplish, but I can’t seem to figure out the audio. The only options I could find for that particular codec is to either create an mpeg-1 and disable the video, or to use the multiplex option under the MPEG-2 settings. The latter, of course, combines and video and the audio, which I don’t want, and both options only export 2 stereo channels when I need unmixed (they requested 8, we have 4). I tried pass-through with the existing Final Cut settings, as well, which gives me the channels I need, but automatically exports the audio as PCM with a bitrate of 144.

  I feel like I’m missing something obvious, but I’m not a super technical person, so no idea what I should do from here. Since they didn’t specify, I don’t see why separate video and audio would be a problem, but I can’t even get the audio isolated with more than 2 tracks. Is there a better way to get these settings? If it makes a difference, I’m using Compressor 3.5.3. Thank you for any help you can provide!
