Glossary-6 Krystal 4300 Reference
Mark Cursor
Allows moves to be made across timeline
without changing the work buffer, thus per-
mitting you to move keyframe work buffer
information from one point on the timeline
to another. The mark cursor appears on time-
lines as a dashed vertical line.
Mask
A pattern or shape used to restrict some vid-
eo processing of a selected area of the input
video. For example, you can use a mask to se-
lect a portion of the source video to defocus.
Master Timeline
A series of keyframes that appear along a
timeline that represents all the currently del-
egated channels of the current effect.
Matte
An internally-generated flat or multiple col-
or signal which is adjustable for luminance,
hue, and saturation. Mattes may be used to
fill areas of keys and borders.
Matte Fill
Using matte to “fill the hole” cut in back-
ground video by the key source.
Matte Key
See Matte Fill.
Menu Display
That part of the Krystal Control Panel where
menus and timelines are viewed.
Monitor
A device used for viewing video signals.
N
Noise
Interference present in a video or audio sig-
nal.
Non-Additive Mix (NAM)
A transition between two video signals in
which only the signal with the largest instan-
taneous amplitude at any point in the picture
is visible.
NV RAM
Non-volatile memory. Computer memory
that persists after power to the unit has been
interrupted.
O
Opacity
Degree of transparency of an image. 100%
opacity is solid. 0% opacity is fully transpar-
ent.
P
Parameter
A numerical value used by a function.
Partial Keyframing Mode
A Grass Valley proprietary type of keyfram-
ing that gives greater effect control on a func-
tion by function basis, and provides
improved path control. When ON, key-
frames are only inserted into the timeline for
functions that have changed. When OFF, tra-
ditional keyframing that inserts keyframes
on all active timeline functions occurs.
Path
Refers to the manner in which interpolated
values change between two keyframes. For
transforms it can correspond to the “path”
which the image on the screen takes to move
from one keyframe to the next. The path may
include size changes, picture rotation, etc.,
depending on the type of channel used in
building the effect. Matte, softness, and other
changes which do not have trajectories also
