Hi Mark
Thanks for getting back to me. I am using DNxHD 145, 8-bit/59.94i. For me, the problem is present in the QT player but also during playback in Avid. Again, this is on Macs only. I can’t reproduce the problem on PCs and I’ve tested playback on three PCs here. The final delivery will be to a tv station which is pc-based for the online edit but our offline editor is mac-based, and he is experiencing the issue. I am trying to determine whether there is corruption in the movie files themselves or in fact this is purely a codec bug for mac systems. I would appreciate your thoughts. Thanks again.
