I have been shooting on Sony xdcam f350 for last 2 years without a hitch. However, recently I transferred some footage to hard drive via xdcam transfer app 2.12.0. When I play the quicktime file it appears to have breakup much like head clog of old 1'' or 2'' inch tape days along with picture break up and hit on audio track. I changed fire wire same problem, I changed disc and shot some footage in the office same problem, I changed hard drive same problem, I tried to transfer footage via Sony pdwf30 deck same problem, I restarted camera and laptop same problem. Even when viewing the proxy file in the larger open xdcam transfer screen it seems to have slight break up.
But when I transferred the footage via xdcam transfer to hard drive from my Sony xdcam f800 set at 35mbps the quicktime file played no problem.
