How many marks are used to create Fit to Fill motion?

• A. Two
• B. Three
• C. Six
• D. Four - two in the Source monitor and two in the Record monitor

Answer: (D)

Fit to Fill motion relies on defining a complete mapping between the source and the target, which requires four reference points. You place two marks in the Source monitor to capture the original fill region (defining its size and placement), and two marks in the Record monitor to specify where and how that fill should land on the target. Those four marks give enough information to calculate the correct scale and position so the fill exactly covers the target area. With only two marks, you wouldn’t have enough data to determine both size and placement; three marks would still leave ambiguity. So four marks—two on the Source monitor and two on the Record monitor—are needed to create the Fit to Fill motion.
