Abstract:

This installment of Cut Lines is Part 1 of a two-part tutorial about Time Remapping in Final Cut Pro (FCP). We’ll take a quick look at Constant Speed Remapping and the mechanics that go into FCP creating it so that you more fully understand why your results look the way they do. My hope is that this understanding will enable you to visualize what the effect will look like before you even apply it, making your workflow faster and your creativity more enhanced.
