  FCP 7 and HD MPEG2 Transport Stream

  Posted by Liam Kerr on April 20, 2011 at 4:33 pm

  Hey guys,

  First time posting. Our international distributor is requesting a digital file delivery in addition to HDCAMS and DBetas. These are the specs:

  Video – Mpeg 2 Transport Stream

  Bitrate : CBR 80Mbps
  Framerate : Native 23.98 / 25 / 29.97
  Resolution: 1920X1080
  Aspect Ratio: 16X9

  Audio

  PCM (AES3)
  Uncompressed 48kHz 24bit
  Channels 1-6: 5.1 where available
  Channels 7-8: Stereo Lt/Rt (Channels 1-2 if no 5.1)

  They make sense to me, it’s just getting to the Mpeg TS wrapper is where the complication arises. Any idea on how to do this through Compressor, or MPEG Streamclip.

  We have XDCAM HD 422 23.98 Masters.

  Thanks in advance
  Liam.

  Compressor can produce Mpeg-2 Transport Streams, but only up to 34mbps. The audio can only be Mpeg-1, not uncompressed.

  These settings are in the Inspector/File Format:Mpeg-2/Extras.

  Your best bet may be looking into Telestream Episode.

  or if you own After Effects CS4 or later you can use adobe media encoder.

  [Liam Kerr] “Bitrate : CBR 80Mbps”
  Where I don’t see the point is in converting 50Mbps stuff (XDCAMHD422) to 80Mbps.
  You will fill your HDs and lose a generation.
  To do that, you need good reasons.

  Thanks for the feedback guys.

  80mbps is the requirement. Still waiting to hear back from our distributor regarding all the specs. I thought I’d get a head start on it.

  He said it’s for delivery to a tv station/network.

  Thats the good reason 🙂

  One of our local stations gets them that same way 80mbps.
  It is over kill, but thats the requirement.

  I strongly suspect a typo. Most broadcasters use data rates around 8Mbs, not 80. I don’t know of any broadcaster anywhere that has the bandwidth to transmit 80Mbs. If they want that, then they are then transcoding to a lower rate which defeats the purpose.

  I would check on the data rate. however, the issue of multi channel uncompressed audio does mean that the task in beyond Compressor.

  not a typo.

  KGW HD only takes mpeg2 streams at 80mbps.
  DirecTV takes them at 50mbps.

  What they broadcast and what they accept as deliverables are 2 different things.

  I will take your word Chris. Strange workflow though

  That’s a “rich men stream”.
  With 80Mbps you can play Broadcast quality 2K/422 and a bunch of PCM audios.
  I want my Chines cable TV like that 😉

  I know, it’s really silly to be jacked up that high.

  I have heard it’s best not to question them though 😉
