Chapter 9 Behaviors 350
Parameters in the Inspector
•
Random Frames: A slider that sets the probability that a frame within the duration of the
behavior is replaced with a random frame. When this value is set to 0, no random frames are
inserted. When set to 100, every frame is random. The default value is 10%.
•
Frame Range: A slider that defines the range from which the random frames are chosen, based
around the current frame. The default value is 10 frames.
•
Duration: A slider that sets the duration of the sequence of random frames. The default value is
1, which means 1 random frame is inserted at a time. When Duration is set to 30, for example,
30-frame sequences (chosen from the Frame Range) are randomly inserted. The Duration value
overrides the Random Frame count (so a new random frame does not interrupt the sequence).
•
Random Seed: A button that picks a new random seed number. This number is used to
generate new values, based on the other parameters of this behavior.
Hold Frame
The Hold Frame behavior holds the frame at the behavior’s In point for the duration of the
behavior. The clip continues playing normally after the behavior’s Out point. For example, if the
Hold Frame behavior begins at frame 60 and ends at frame 300, the clip plays normally until
frame 59, frame 60 is held for 240 frames, and then normal playback resumes—frame 61 of the
clip—at frame 301.
The Hold behavior is applied at the current frame, rather than at the start of the object.
Parameters in the Inspector
•
Offset: A slider that sets the offset for the hold frame. When set to 0 (the default), the frame
at the start of the behavior is the hold frame. When set to 60, however, the frame at the start
of the behavior (the hold frame) is the start frame plus 60 frames. This parameter is measured
in frames.
Tip: Flickering might occur if the Hold Frame behavior is applied to interlaced footage. To
avoid this, ensure that Field Order is properly set in the Inspector. To change field order, select
the footage in the Media list, open the Media pane in the Inspector, then choose a field order
option from the Field Order pop-up menu.
Loop
The Loop behavior loops a segment of the clip within the duration of the behavior. The loop’s
starting frame is derived from the start frame of the behavior. For example, if the behavior is
applied at the start of a clip, and Loop Duration is set to 30, the first 30 frames of the clip loop
repeatedly until the end of the behavior. At the end of the behavior, normal playback resumes
from the frame at the end of the loop duration.
Parameters in the Inspector
•
Loop Duration: A slider that sets the duration of the looped frames. The default value is
30 frames.
Ping Pong
The Ping Pong behavior “ping-pongs” playback of a segment of the clip within the duration of
the behavior. The ping-pong’s starting frame is derived from the start frame of the behavior.
For example, if the behavior is applied at the start of a clip, and Duration is set to 30, the first 30
frames of the clip play forward, then play in reverse, then forward, and so on until the end of the
behavior. At the end of the behavior, normal playback resumes.
