560 Chapter 20 Rotoscoping
To paste a keyframe:
1 Move the playhead in the Time Bar to the frame where you want to paste the copied
keyframe.
2 Right-click the transform control of the desired shape, then choose Paste Keyframe of
Shape from the shortcut menu.
Adding Blank and Duplicate Keyframes to Pause Animation
If you want a shape to be still for a period of time before it begins to animate, insert a
pair of identical keyframes at the start and end frame of the pause you want to create.
If you want to delay a shape’s animation for several frames beyond the first frame,
insert a keyframe with no animated changes at the frame you want the animation to
begin, then modify the shape at the keyframe you want to animation to end.
To manually add a keyframe without modifying the shape:
m Click the Autokey button off and on.
A keyframe is created for the current state of the shape. If the shape is already
animated, the state of the shape at the position of the playhead in the Time Bar will be
stored in the new keyframe.
Shape Timing
Three parameters within the timing subtree of the RotoShape parameters allow you to
modify when a rotoshape starts and ends. An additional retimeShapes control lets you
retime all keyframes that have been applied to that RotoShape node, speeding up or
slowing down the animation that affects the shapes within.
timeShift
Offsets the entire rotoshape, along with any keyframes that have been applied to it.
This parameter corresponds to the position of that rotoshape in the Time View.
inPoint
Moves the in point of the rotoshape, allowing you to change where that rotoshape
begins. This parameter corresponds to the in point of the rotoshape in the Time View.
