Dropped frames – These are individual images missing from the video data stream, usually
due to a slow hard drive.
DV – DV stands for Digital Video. The DV standard uses a compression rate of 5:1. This
corresponds to a data rate of 3.125 Mbps, which can be handled by virtually all newer hard
drives. The quality of the DV standard is very high; it is therefore frequently used in
professional productions. A number of different cassette types exist in the DV sector, which
vary in size and maximum playing time, but which are compatible with one another in terms
of video data. MiniDV is designed for the consumer sector and supports playing times of up to
one hour. The DV format used in the professional sector supports playing times of up to three
hours.
DV-In – Usually, the DV jack of a camcorder can transport video data in both directions—to
and from the camcorder. Many camcorders in Europe do not feature DV-In, however. Also see -
> Enabling.
Enabling – Due to European import duties, imported digital video recorders are more
expensive than imported digital video playback devices. For this reason, manufacturers of
camcorders have begun to modify their products for the European market and to disable the
digital input -> DV-In. Needless to say, clever developers found a way around this restriction
very quickly. This is known as “enabling”. Enabling the DV camcorder is a precondition for
sending video material back to the camcorder. Enablers are available for almost all
camcorders and can be purchased freely.
Fading – Fades are soft transitions, often involving special effects, from one clip to the next.
Fields – Rather than displaying 25 frames per second (as per the PAL standard), 50 fields are
displayed per second to reduce TV display flicker. These fields consist of either the odd-
numbered rows (these are sent first) or the even rows of the image being displayed.
FireWire™ – Apple's name for -> IEEE 1394
Frame rate – The number of frames within a given period of time. The frame rate is frequently
stated in frames per second (FPS).
Hi8 – Analog video recording system that separates color and brightness information, thus
offering quality better than that of VHS-C, for example.
“Hosiden” mini-DIN connector – A small connector with four conductors used for -> S video
signals.
IEEE 1394 – This is a universal bus system originally developed by Apple for digital data
communications. The devices are connected by cables with a maximum length of 4.5 m. The
system supports transfer rates of up to 400 Mbps. However, a standard has not been
