Re: drift / sync issue with ProRes playback
by Rich Rubasch on Jun 12, 2008 at 8:10:19 pm

Hi guys....We discovered the same issue today. Ours has more than sync drift, we are also seeing a sort of judder on playback. We tested the crap out of it with all kinds of source tapes, setting the deck differently internally, easy setups, sequence settings, control panel etc. Here's our findings. DVCProHD worked perfectly. ProRes422 HQ worked just fine. ProRes422 DID NOT KEEP SYNC.

This was ALL 1080i 24p footage.

DVCProHD runs at 14mbps, ProRes HQ runs at about 28 mbps and ProRes runs at about 18 mbps.

2008 Quad Core MacPro
Leopard
QT 7.4.5
Either Kona 5.1 or Kona 5.1 NDD
Kona 3 card with breakout
Panasonic 1200A deck


Only DVCProHD and ProRes HQ got the job done.
