Doing some relatively simple rescue work of some AV synch issues for a friend. Getting "Attempt to position before start of file result code == -40" when I try to bounce the tracks. This is my process: import QT with badly dithered/buggered audio (for visual confirmation) import 16bit AIF of badly dithered/buggered audio import new and improved 24bit file. Synch up waveforms by eye. Lock 24bit track Close QT window and delete Movie track and bad AIF. Add 2-pop (a 48k/24bit file) so all remaining files are 48KHz/24bit (2-pop is for lining up in an HD edit system, the original bad files were badly processed somewhere along the line) Go to bounce. I can only get it to go past the error message if I choose a dither option. Every other combo of file format, resolution, stereo file type and bounce mode force the error. Essentially if just won't go unless it dithers. I had to deliver some of the files right away so I chose dithering 24bits to 24bits wich shouldn't dither at all but who knows what the hell is going on at that level. Resulting files are 48K/24bit according to Logic Audio window. OSX 10.3.9 Logic 6.4.1 Dual 1Gig G4, 1.5GigRAM RME Multiface Others have had this problem but I couldn't find any sign of anyone working it out. I am near a 7.0 upgrade so it would be nice to know if this occurs in 7.0 and up. thanks slick ----------------------------------------------------------------- LUG Group Buy for Serato's Pitch n' Time LE until June 14th!
