DirectDraw
– DirectDraw is a graphics standard initiated by Microsoft. Its features include the
capability to write graphics data directly to the memory of the graphics board for the fluid
display of video material.
Dropped frames
– These are missing individual images in the video data stream that are
mainly the result of using a slow hard drive.
DV
– DV stands for Digital Video. The DV standard uses a compression rate of 5:1. This corre-
sponds to a data rate of 3.125 Mbps, which can be handled by virtually any modern hard
drive. The quality of the DV standard is very high; it is therefore frequently used in profes-
sional 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 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
– As a rule, the DV socket of a camcorder can transport video data in both directions—
to or 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 expen-
sive than imported digital video playback devices. For this reason, manufacturers of camcor-
ders have begun to modify their products for the European market by disabling 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.
Fade
– see Fading
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 frames 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 to be 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 better quality than VHS-C, for example.
Hosiden connector
– A small connector with four conductors used for -> S video signals.
