Probably nothing creates a more arresting effect than having a clip change speed during playback. Watching a clip slow to a still frame, hold for a graphic to appear, then restart can make even a boring presentation seem interesting.
In this short, step-by-step tutorial, Larry Jordan compares the differences between a constant speed change and a variable speed change, shows you how to create an artistic effect using keyframes in the Viewer, or make precision adjustments using the Time Stretch tool in the Timeline. As well, he illustrates how to ramp into or out of any keyframe using Bezier curve controls. When then tutorial is done, you’ll be able to easily create your own variable speed effects.
