DVD –
Abbreviation for “Digital Versatile Disk”. The diameter of a DVD is the same as that of a CD-ROM.
Current DVD specifications cover storage capacities ranging from 4.7 GB (DVD-5) to 17 GB (DVD-18) and
data rates between 600 and 1,300 Kbps. Distinctions are also made between a variety of formats such
as DVD Video, DVD Audio, DVD-ROM, DVD-R, DVD-RW and DVD-RAM.
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.
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 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 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 communica-
tions. 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 established for video data due to
the lack of specifications for the format of video data using this bus. Sony got down to brass tacks and
closed this gap by installing FireWire™ sockets in its digital camcorders and developing its own
protocol. Thanks to FireWire™ and the Sony protocol, the dream of loss-free video editing has finally
come true.
iLink
– Sony's name for -> IEEE-1394
Interlacing – see Fields
Linear editing
– The origins of linear video editing date back to analog video. The original video data is
generally present in the same sequence as the edited video clips. A simple type of linear editing would
be, for example, transferring video material from an analog video camera to a video recorder while
discarding a number of clips. If you then insert a new clip in the middle, however, all of the following
clips will also require editing.
Luma keying
– Unlike chroma keying, the transparency of the video is determined on the basis of
brightness in luma keying.
Luminance
– Luminance refers to brightness in -> YUV. (Y)
