  Starnge Sync problems when exporting_ Ppro_BMD Extreme

  Posted by Esteban on October 12, 2005 at 1:24 pm

  Hello
  I cant find a solution to this problem:
  playing from an uncomp 8 bit timeline all looks good , no droped frames nice clean in sync image and audio ..( 3:40 total time)
  if I export that to say: bmd8bit avi, or QT (sorenson, bmd, none, or any other codec)

  the exported file losses sync around 1 min after playing..!
  why?
  if I see it ok playing from the ppro timeline, but an exported file dosent no matter what format.
  the audio file in the timeline is a .aiff 44hz stereo, and I’m playing audio throug the internal audio card not the BMD Extrme card
  all playing form RAID 0 sata drives..
  I dont think is a playback issue because the same file in other machines present the same sync slip…in the exported clip.. and the entire project playsback from the timeline with no problems at all..

  what to check when exporting?

  audio interleave 1, 0 frames?

  audio latency? has anything to do..
  I just need an uncompressed Quicktime and a web version…

  some ideas?

  Audio format should be 16bit @ 48khz.

  Please can you forward your system configuration including software and hardware details to
