Hello, we finally discover that the problem was cause by the AJA driver 9.1. We tried on 2 different machine ( one 10.6.8 and one 10.7.2 ), both running FCP7. We also tried two different decks ( HDCAM and HDCAM SR ), both machine are offsync by 2 frames on input and on output.
Both when we downgraded the AJA driver to 9.05, everything is back to normal, no offsync. This is confirmed on 2 different machines with 2 different OS and 2 different deck.
Can you confirmed that on your side? Has this been tested prior of the release??
Thank you!
