Mini DV or HDV tape transfer.
This video format used Long GOP compression to write High Definition video onto magnetic tape. This was the same tape that Mini DV camcorders and video decks used for Standard definition video. Most of the HDV video tapes had a 60 minute runtime.
Please note that there is no way of telling if your Mini DV tape has been recorded in SD or HD until you put it into a deck or camcorder. A Mini DV camcorder or deck will not be able to play a tape recorded in the HDV format, but an HDV deck will play both formats.
The most widely used HDV camcorder was the 3 CCD Sony Z1. (pictured above Sony FX 1 E ).
