Terminology
AVI
– a Windows video format.
Blending
– see Overlay
Blue Screen
– A variation of the Chroma Keying
Capture
– as in record.
Chroma Keying
– Chroma Keying uses a single colored background where, for example, an
actor or actress is overlaid. The background can then be made transparent, allowing another
background to be blended in.
Chrominance
– Chrominance describes the color signal in YUV, which is a combination of two
color combinations. U, the balance between Red and Cyan and V, the balance between Yellow
and Blue.
Clip
– A short piece of recorded video material.
Composite Video
– Composite Video is a standard consumer transfer method, normally an
RCA jack (Cinch) and often used on televisions and VCRs. Using this method all signals
(Chrominance and Luminance) are sent through one cable. The quality of Composite Video is
not as good as S Video, where Chrominance and Luminance are sent separately.
CPU
– Central Processing Unit. The part that really works, the processor, e.g. Pentium or
Athlon.
Data Transfer Rate
– This is the amount of data your drive continually reads or writes. This
value is typically measured in seconds, e.g. 7 MB/sec..
Device Control
– this represents the ability to steer your DV camcorder from the PC.
DirectDraw
– DirectDraw is a graphic standard started by Microsoft. One advantage of this
standard is that data can be written directly in the graphic card memory, e.g. for smooth video
playback.
Dropped Frames
– These are the single frames that are lost from the data stream during
recording, usually due to a slow hard drive.
D8
– Digital 8 is the logical conclusion to the Hi8 and VHS camcorder formats. It continues to
use Hi8 or D8 cassettes but records in DV format.
