Glossary
AVI – A Windows video format.
Bit rate – The bit rate indicates the volume of the data stream per second. A higher bit rate
results in higher quality. A distinction is made between constant bit rates (for -> VCD, for ex-
ample) and variable bit rates, e.g. for -> SVCD and -> DVD. Unlike constant bit rates, variable
bit rates adjust the data stream to suit the video material.
Blue screen – A variation of -> Chroma keying
Capture – Recording.
Chroma keying – Chroma keying uses a surface with a single color in front of which an actor,
for example, is filmed. This color area is then made transparent during subsequent editing
and can be replaced by a different background, for example.
Chrominance – Chrominance refers to the color signal in -> YUV, which consists of two color
components: U, the balance between red and cyan, and V, the balance between yellow and
blue.
Clip – A short piece of video material.
Composite video – Composite video is a transmission method common in the consumer sec-
tor that is generally realized using cinch connectors and which is frequently found on TVs. In
this process, all signals (chrominance and luminance) share a single cable. The quality of
composition video is lower than that of -> S video, for example, in which chrominance and
luminance are transmitted separately.
CPU – Central processing unit. The part of your computer (the processor, i.e. Pentium or Ath-
lon) that does the actual computing.
D8 – Digital 8 is the successor to the Hi8 and VHS-C camcorder formats. Hi8 or D8 cassettes
are still used, but the video data is recorded digitally in DV format.
Data throughput – see Data transfer rate
Data transfer rate – The data transfer rate describes the speed at which a hard drive can read
or write data over a sustained period. The data transfer rate is usually measured in seconds,
e.g. 7 Mbps.
Device control – In the DV terms, this refers to the ability to control your camcorder from your
PC.
