  DVC HD Pro sync problems

  Posted by Jake Martin on July 27, 2009 at 3:31 pm

  Hi

  Here is my problem. I am working in a DVC HDPro50i codec and FCP sometimes plays clips in sync and sometimes not. I have also tried Pro Res and it played in sync for a while but then it did not. At it’s worst when I hit play I get an audio delay making it impossible to edit. I have tried several playback offsets but that doesn’t help.

  Here is some background to the project. An edit assistant captured the DVC HD Pro footage via firewire on a single processor PPC G5 and reported it was coming in out of sync.

  I am now editing in a pal project 48KHz 16 bit on an eight core mac with a blackmagic card and working from sata drives.

  Other issues of note is that the quicktimes are also out of sync and worryingly FCP has also reset about 80% of the clip time-codes to 00:00:00:00.

  I have been working on FCP 6.05 but have now upgraded to FCP 7 with no success. I have done the usual maintenance thrashing prefs etc.

  I would really appreciate some help with this, I have pressing deadlines this week and a film I can’t cut.
  Many thanks for reading

  Post script to the above:

  What I am noticing is that the seq will hold sync until I make any sort of audio edit then the edited clip loses sync and most others seem also to be effected.

  Sounds like the media was captured on an incorrectly configured system. Do you have access to the originals ? You probably need to recapture…or at least be able to examine it for troubleshooting.

  For what its worth, it sounds like it was captured via Firewire on a drive sharing the same bus as the deck/camera. This can work fine with DV, but with HD, it can be problematic.

  Could be other stuff too..but since your assistant indicated there were problems during capture, the media is probably bad.
