strange sync issue
on Jun 6, 2010 at 9:15:53 pm

Hi. Captured via AJA card DVCPRO50 from DigiBeta Pal. Sync is fine on tape. Viewing material in the timeline audio sync drifts. Sometimes it is fine sometimes it can be way out (10 frames). Audio monitoring is via the AJA out but we have tried monitoring the mac's audio out and it is the same. Video cuts in the timeline are the same in the canvas and on external SDI monitor. When we lay back to tape all is fine agian. Any suggestions/similar experiences?
Matt.

Have you tested your drive speed with AJA System Test? How full is your drive and what kind? Did you trash prefs & repaired permissions?
