DV Digital Video. Refers to the capturing, manipulation and
storage of video in digital formats. The DV format is an
international standard intended for consumer use created back
in 1995 by a consortium of companies.
DVD Digital Versatile Disc. DVD is a high capacity CD-size disc for
video, multimedia, games and audio applications.
DVD-ROM A read-only format, it is similar to the CD-ROM format for
compact discs but holds up to 4.7 GB for single-side and single-
layered discs. More common today is the single-sided and
dual-layered 8.5 GB discs. Further down the scale is double-
sided and single-layered 9.4 GB discs and double-sided and
dual-layered 17 GB discs.
DVD-RW DVD-RW (formerly DVD-R/W and also briefly known as
DVD-ER) is a phase-change erasable format. Developed by
Pioneer and based on DVD-R, it uses similar track pitch, mark
length, and rotation control. DVD-RW is playable in most DVD
drives and players. Capacity is 4.7 billion bytes and can be
rewritten about 1,000 times.
DVD+RW DVD+RW, supported by Philips, Sony, Hewlett-Packard, etc.,
is an erasable format based on CD-RW technology. It is not
supported by the DVD Forum (even though the DVD+RW
companies are members), but the Forum has no power to set
standards. DVD+RW drives will read DVD-ROMs, CDs, DVD-
Rs and probably DVD-RWs, but will not read or write DVD-
RAM discs. The drives can also write CD-Rs and CD-RWs.
DVD+RW discs, which hold 4.7 billion bytes per side, should
be readable in most existing DVD Video players and DVD-
ROM drives. It can be rewritten about 1,000 times (down from
100,000 times in the original version).
flip video This option is for certain video formats (such as YUY2)
provided by some hardware capture devices which will might
be displayed as upside-down during recording.
fps Frames Per Second. A measure of how much information is
used to store and display motion video. The term applies
equally to film video and digital video. Each frame is a still
image; displaying frames in quick succession creates the
illusion of motion. The more frames per second (fps), the
smoother the motion appears. In general, the minimum fps
