Yes, I did an Audio Mixdown, but the distortion still occurs and only on output to tape. The QT fil and the sequence both play fine.
Since this particular tape was for mastering to the very few clients that use VHS, I finally burned the QT to a DVD and reimported – certainly not an ideal solution with extra compression and generation loss, but they had to send the tapes to the Dupe house today along with the DVD master.
I wonder if the media somehow becomes corrupt on output. The issues are always at the same places in the program.
I am an Apple Trainer for FCP, but I tell you I am stumped on this one!
