HDV High Definition Video. The format used to record HDTV-quality data with video camcorders.
hue The distinction between colors (for example, red, yellow, and blue). White, black, and gray tones are not
considered hues.
I
i.LINK Sony® trade name for IEEE 1394.
IEEE 1394 The interface standard that enables direct transfer of DV between devices, such as a DV camcorder and a
computer. IEEE 1394 also describes the cables and connectors utilizing this standard. Also called FireWire or i.LINK.
See also “
USB ” on page 308.
image stabilizer Also referred to as electronic image stabilizer. A technique used to remove the movement caused by
camera shake.
interframe compression A compression scheme, such as MPEG, that reduces the amount of video information by
storing only the differences between a frame and those preceding it.
interlacing A system developed for early TV and still in use in standard TV displays. An electron gun illuminates the
phosphors coating the inside of the screen, first drawing the even, and then drawing the odd horizontal lines across
the screen. By the time the even lines are dimming, the odd lines are illuminated. We perceive these interlaced fields
as complete pictures.
interpolation A method for establishing new data points between known data points.
J
J-cut An edit in which the audio starts before the video, giving the video a dramatic introduction. Also known as an
audio lead.
JPEG Joint Photographic Experts Group. Also, a file format defined by that group for compressing still images.
Because video is a sequence of still images, JPEG compression can be used to compress video. See also “ MJPEG ” on
page 304.
K
key A method for creating transparency, such as a bluescreen key or a chroma key.
keyframes Start and end points for animated effects. Adobe Premiere Elements automatically generates the frames
between keyframes to create smooth movement. See also “ interpolation ” on page 303 and “ tweening ” on page 307.
keying Replacing part of one TV image with video from another image. Also called blue screen. See also “ chroma key ”
on page 300.
L
L-cut An edit in which the video ends before the audio, which acts as a subtle transition from one scene to the next.
To perform an L-cut in the Timeline window, hold down the Alt key and drag the right edge of the video to the left;
the result looks like the letter L.
letterbox A technique used to preserve the original aspect ratio of a motion picture when played on a TV. Letterboxing
adds black bars to the top and bottom of the screen.
lossless A compression scheme that doesn’t affect signal quality, such as the transfer of DV via an IEEE 1394
connection.
