To shift a node in time: m Drag an image node in the Time View to the left or right. That node's timeShift parameter changes, and the start and end frames of the node are moved together. The inPoint and outPoint parameters, however, remain the same, since this operation does nothing to change the clip's duration. All compositing nodes that are attached to a time-shifted image node are automatically shifted in time to match. When you drag a non-image compositing node in the Time View, such as a layering node, the timing of all image nodes connected to it is also modified. In the above example, when the Over1 node is dragged, all nodes above the Over1 node (including the invisible Pan1 node) are shifted, as well. This means that the frames of bus2 are shifted in time, and any animation curves on Pan1 and RGrad1 are shifted as well. If you drag only the bus2 clip, then only the bus2 clip is modified in time-unless the Shift Curves control (in the bottom-left corner of the Time View) is activated. When the Shift Curves control is enabled, all curves that are attached to the shifted nodes are shifted as well, so the animation is carried with the shift. This control is enabled by default, and in most cases should be left on. Important: If Shift Curves is disabled, the curves remain locked in their previous positions, and will be offset from the new position of the clip. Adjusting an Image Sequence's firstFrame and lastFrame Parameters You can trim frames off of the beginning or the end of a clip by adjusting its firstFrame and lastFrame parameters-either in the Source tab, or in the Time View. Note: QuickTime movies do not have firstFrame and lastFrame parameters. Chapter 8 Using the Time View 265
