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.

The HUD contains the Offset parameter.
Loop
This 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.
HUD Controls
The HUD contains the Loop Duration parameter.
Ping Pong
This behavior “ping-pongs” 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.
