Chapter 8 Using the Time View 267
You can change the repeat mode of an extended-duration clip at any time using the
controls in the Timing tab of that image node. A clip’s repeating behavior is controlled
by the inMode and outMode parameters in the Timing tab of the FileIn parameters.
The inMode parameter controls the looping behavior of frames between the firstFrame
looping handle and the inPoint, and the outMode parameter controls the frames
between the outPoint and the lastFrame looping handle.
The following table lists the available repeat modes.
Mode Result Example
Black No frames are repeated. Instead,
black frames are inserted.
Freeze The first/last frames are repeated as a
freeze-frame.
Repeat The clip is continuously repeated,
always starting from the first frame.
Mirror The clip repeats, first in reverse order,
and then forward, indefinitely. To
provide a smooth transition, the first
frame does not repeat between the
loops.
Inclusive
Mirror The entire clip repeats, first in reverse
order, and then forward, indefinitely.
