MicroMV

MicroMV is a proprietary videotape format introduced in October 2001 by Sony. It is the smallest videotape format — 70% smaller than MiniDV or about the size of two US quarter coins; it is also smaller than a Digital8 or DV cassette and slightly smaller than an audio microcassette. It was the first helical scan tape system using MR read head introduced to the market. Each cassette can hold up to 60 minutes of video.

The MicroMV format does not use the "DV25" codec used by the highly popular DV & MiniDV videocassette formats. Instead, it uses 12 Mbit/s MPEG-2 compression, like that used for DVDs and HDV. Footage recorded on MicroMV format initially could not be directly edited with mainstream DV editing software such as Adobe Premiere or Apple Final Cut Pro; instead Sony supplied its own video editing software MovieShaker (for Windows PCs only). Later versions of Ulead Video Studio and several freeware applications however could capture and edit from Sony MicroMV Camcorders.

MicroMV was unsuccessful. Sony was the only electronics manufacturer to sell MicroMV cameras. In 2006, Sony stopped offering new MicroMV camcorder models. In November 2015, Sony announced that shipment of MicroMV cassettes would be discontinued in March 2016.
