No, you just had to play every take to confirm no drop outs ;-) At least
BetaSP was better than 3/4 inch, which was better than 1 inch, which was
better than 2 inch, which was not nearly as good as 16 mm. When I talked to
my editor, whose DSR-11 generated the MiniDV tape, he said look at the
video. There will be problems on at least one frame in the region of the
audio drop out. He was right. Five out of six affected frames had several
places on the frame with empty pixels (little square blocks of emptiness).
