  720p to 1080i

  Posted by Rob Tobin on December 4, 2009 at 12:26 am

  I used a aj 1800 to cross convert 720p to 1080i on ingest. I had SD black burst to both deck and FCP.
  It seems that the audio is -3 frames out of sync. I’m using a 2×2.26 quad and a Kona LHe. I used Prorez
  HQ as the codec. I used the Prorez easy setup which defaults to the RS-422 sony VTR B which has a -2.0 capture offset vs the Panasonic 59.94 -2.5. Can anyone explain the VTR A verse the VTR B? Was this
  my problem? Should I use the Panasonic set-up? Is it better to do the cross conversion through the KONA
  on the way in? I was mixing with other 1080i material and needed to master back to 1080i (reason for not editing native 720p)
  Thanks
  Rob
