You can make a clip begin at a certain frame by using the slip function. This applies only to clips loaded into the Modular Keyer via the Desk node. When you link a clip loaded via the Desk node into the Modular Keyer pipeline, it retains its clip controls.

The Slip field and Lock button appear in the Modular Keyer menu. If the node bar appears, swipe the bar at the left or right of the Modular Keyer menu.
For example, a slip value of -15 holds the clip at the first frame and repeats it 15 times before the clip begins. A slip value of 10 begins the clip at frame 11, since a slip value of zero corresponds to frame 1. Slip information is stored with Modular Keyer setups.
