Dropouts are caused when tape cannot record/play
signal properly when passing over the record/play
heads - signal is missing (it may be due to tape mfgr.
defect, dust, tape wrinkle, whatever...). In analogue
video, the result is "sparkles", light scan lines,
or complete frame noise; in DV there is error correction that takes small squares from the previous frame to
cover errors in the current frame (you see brief
mistakes in the motion parts of the frame, but unless
the dropouts are pretty bad, they generally aren't
very noticeable in DV).
