Thanks very much for the info, Angelo. It’s a workflow that we do all the time, even down to the routing hardware and 3G provider (Etisalat, Dubai), so I’m not sure why for these two cameras is should be broken and others work. Normally, if we have upload fails we get easily-viewable visual errors – and Quicktime churns these out as video files no problem.
One more thing I tried was to use QT to make reference video files, then output from FCP, but this brought back the dreaded “General Error” so I guess issue is one of a few bad files. Too many to isolate and recompress, however, so for now I’m carrying on with the ‘hack’ of exporting as fullsize 422 then doing the rotation/resizing required in FCP.
thanks
