VS X10 Video Mask - Any Ideas?

[KinsmanFarm]

Hello. I am faced with the challenge of highlighting each fairway on a golf course (18 in all). The video is from a drone moving down each fairway at a height of a about 30-m (100-ft). With each individual hole, I want to mask out the adjacent fairways and thereby highlight the single hole.



I have exhausted the possibility of using "Mask Creator" in video mode.

Someone here may have a creative way of doing this.

In the end, I'd like to have the single hole (fairway and green) surrounded by an out-of-focus blur, or fringes that fade to white background as the video proceeds from tee to green. Note that fairways are not always straight (neither are my tee-shots, but the two rarely align).

Thanks for thinking about it.
