268 Chapter 8 Using the Time View
Clips With Infinite Duration
Image nodes such as RGrad and Ramp have no preset range because they are
generated by Shake. In the Time View, these types of nodes have infinity symbols on
their left and right edges, indicating that these images have no end. To limit these
nodes, grab the handles as you would with clip nodes.
Customizing How the Last Frame Is Represented
The Out point of an image node represents different things to different users,
depending on which media applications they’re used to. For video editing applications
(usually), an Out point is the frame at which there is no more image (and is therefore
black). For a clip of 50 frames, video editing applications usually consider the Out point
to be frame 51. For CG artists, the Out point is the last frame to render, making it frame
50 in this example. To add to the confusion, keep in mind that even if you have 50
frames, you have meaningful information up to frame 50.99999—incremental frames
are necessary for motion blur calculations and field rendering.
You can right-click in the empty part of the Time View to reveal a shortcut menu that
lets you change how the Out point is represented. The shortcut menu contains the
following options:
In/Out Point Display
This option toggles the display of the In/Out point in the Time View. When enabled, the
In and Out points are displayed whenever you click the end of a clip.
