The MiniDV Video Format
MiniDV is a digital video tape format which, for a while, was the most popular format for home video cameras. MiniDV uses the same compression as DV.
MiniDV cassettes are 65 x 48 x 12 mm. Record time is 60 minutes (standard play) or 90 minutes (extended/long play). 80/120 minute tapes are also available.
MiniDV can also be used to store other forms of data with the help of appropriate software. MiniDV tapes can hold about 13GB od data in this way.
