  QT files from Avid Meridien

  Posted by David Mcsween on June 29, 2005 at 1:44 am

  We have an annoying problem with Avid Compressed CODEC footage (from the old meridien type Xpress machines) coming into AE with vertical banding (not solid stripes but subtle changes in luma).
  It seems to be present in the file directly after exporting from the Avid. We can’t use Ref files as the AE PC isn’t on the Avid Unity system (Avid File sharer).

  Will the new OMF import fromAvid fix this? or is it the same CODEC repackaged??

  Cheers David

  Hi David,

  strange problem, I’ve been using the Avid meridian/AE combo for five years and never come across it. A couple of quick things to check however.

  1. Are you sure that the codec installed in your AE machine and and your Avid are exactly the same?

  2. Check that none of the video is over 235 in the avid as historicly anything above peak white has sometimes caused difficulty

  sorry I can’t be of more help. If you use Automatic Duck you could try e-mailing Wes Plate, AD head honcho and guru on Avid/AE interoperabilty issues

  good luck

  Angus

  Yes all the settings are for video levels and AE is seeing it as an Avid QT file. It may be a bug with the PAL version of the pluggin, another fault is not formating for widescreen properly when it is selected as an output type (you get a letterboxed version).

  Also I have recently noticed that the AE 6.5 ‘DV OMF export’ doesn’t support PAL 4:2:0 rather 4:1:1 which probably gets contracted to 4:1:0 in PAL Avid. And I can’t get the Avid DV (standalone) codec to export a recognisable file for Avid. It just appears in the Avid as a grey screen, even though it imports as a supported QT file.
  Go figure!

  Cheers David
