Video effect paths
Video effects have paths which determine how the effect plays from keyframe to
keyframe.
Aurora Edit has four path types:
Description Example Path
Type
The effect characteristics hold for the duration of
the keyframe and then change instantaneously to Hold
the next keyframe. For example, the image jumps
from its location in one keyframe to a new location
in the next keyframe.
The effect plays in a constant direction and at a
constant rate of speed from keyframe to keyframe. Linear
For example, the image moves from one location
to the next in a straight line at the same speed.
The effect plays in a constant direction but at a
variable rate of speed from keyframe to keyframe. S-Linear
For example, the image moves from one location
to the next in a straight line; it begins slowly, speeds
up, then slows down again as it approaches the next
keyframe. Because of the changing speed, S-Linear
changes appear less abrupt than linear changes.
The effect plays in a variable direction and at a
variable rate of speed, causing a rounded path Curve
through the keyframe. For example, the image
moves from one location to the next in a smoothly
curved line. The Curve path is the least abrupt type
of path control; both direction and rate of speed are
kept smooth and steady in appearance.
