ball flight tracker

[Main Street Insurance]

is it possible to create a line of some sort tracking the flight of a golf balls flight in a video?

You can always try the standard 2D tracker and fetch the data to a particle system that leaves a visible trail. Even the "dumb" CC Particle Systems II will do that sufficiently. Don't expect too much, though. If it took a slowdown to even make the ball visible, a tracker isn't going to be able to do much with those 10 frames. The camera perspective is just not ideal to produce a consistent motion/ tracker path.

That shot has frame rate problems and the ball is only visible for a few frames so the best you can do is make a guess at the path, draw a path with the pen tool on a shape layer, then add a trim fPath's animator.
