Chapter 8 Using the Time View 263
Clip Durations in the Time View
The duration of image sequences and movie files (hereafter referred to as clips)
referenced by a FileIn node is simply that of the source media on disk. The duration of
single image files, and of image nodes generated by Shake, is considered to be infinite.
When two or more nodes are combined, as with the Over or MultiLayer node, the final
duration is that of the longest clip in the operation.
When a FileIn node is created, its timing parameters are referenced via that node’s
Timing tab in the Parameters tab. Other image nodes have a timing subtree within the
main Parameters tab. Additional nodes that are connected to a clip inherit the source
clip’s timing. You cannot adjust the timing of non-image nodes.
Adjusting Image Nodes in the Time View
In the Time View, nodes representing images (whether clips, single image files, or
Shake-generated images such as gradients and rotoshapes) have several controls
attached to them. Handles at the beginning and end of image nodes allow you to
adjust their timing, while other controls let you load parameters, ignore and “unignore”
nodes, and perform other functions.
Trimming and Looping QuickTime Clips and Still Images
The methods described in this chapter for trimming and looping clips in the Time
View do not work the same with QuickTime clips, Still Images, or Shake-generated
images. The following exceptions apply:
• QuickTime clips cannot be trimmed using the timing handles, because QuickTime
clips do not have corresponding startFrame and endFrame parameters in the
Source tab of the FileIn parameters. However, QuickTime clips can be looped for
their full duration.
• Still Images and Shake-generated images cannot be looped, as a single image’s
duration is infinite by default.
