Learn about changing the Min % Pixels Used property to change the tracking results.
- [Instructor] Let's return…to the Amend Percentage Pixels Used property…in the track module and discuss…how that affects your tracking.…So here I am in 3.9City…and I have a shape over the top…of this building.…Now whenever you draw a shape, or a spline,…as an X spline or a Bézier, the program actually selects…a minimum percentage pixels for you.…If it's a relatively small spline,…it's going to be a large value.…If it's a big spline, it'll select a small value.…And this is the minimum percentage…of pixels it uses to find the pattern over time.…
It might use more but this is where it starts.…Now this is a fairly easy shot to track…so I don't actually need 90%.…I can crank this down to 10%,…make the tracking more efficient…and still it'll work fine.…I'll track forward, you can see…that there's no problems.…So you can change this value…to make your tracking more efficient.…If it's a easy track, consider lowering this value.…Let's try the opposite.…
I'm going to put up a new project.…Open project.…This time I'll open 3.9Table.…
