Apple Final Cut Pro 7 - Manual (Page 1989)

wipe A transition in which a geometric or grayscale gradient is used to transition between
two clips.
wipe pattern One of several standard SMPTE wipe transitions recognized by EDLs. Because
the EDL format continues to reflect the simplicity of older systems, many Final Cut Pro
transitions have no equivalent in a given EDL format. Therefore, during the EDL export
process, these new transitions are automatically mapped to the closest approximate
SMPTE standard wipe pattern.
wireframe modes Viewer and Canvas view modes that show the outline of a clip’s video
frame. Clips in the Viewer and Canvas can be viewed in Wireframe mode or
Image+Wireframe mode.
x Refers to the x coordinate in Cartesian geometry. The x coordinate describes horizontal
placement in motion effects.
XDCAM Sony optical disc format for recording DVCAM and IMX video within MXF
container files.
XDCAM HD An extension of the Sony XDCAM format that supports high definition video
recording at three quality levels. XDCAM HD uses long-GOP MPEG-2 compression similar
to the compression used in HDV.
xmeml Abbreviation for eXtensible Media Editing Markup Language. The custom set of
markup tags used by the Final Cut Pro XML Interchange Format.
XML Abbreviation for Extensible Markup Language. XML is a method of storing information
in an easily accessible yet customizable file format. XML files are plain ASCII text files used
by Final Cut Pro for data exchange among different applications and operating systems.
Xsan Apple software for clustering multiple RAIDs together into a storage area network
(SAN). Multiple computer systems can read and write to the shared storage area
simultaneously, allowing several editors to work in parallel using the same media files.
y Refers to the y coordinate in Cartesian geometry. The y coordinate describes vertical
placement in motion effects.

zebra stripes Animated diagonal “marching lines” that are superimposed over areas of
an image that are very near or exceed the broadcast-legal limits. Zebra stripes are turned
on when you use the Final Cut Pro range-checking options.
