NBC: The Thin Yellow Line
A nice report on “how does the yellow line appear on football fields in TV” is shown below at FANDOME. The company doing it is called SportsMedia. They use a combination of tracking systems, pipe it through the camera’s 2nd audio channel to their computers and have two operators for adjusting the line’s position and controlling the chroma keying for the players above the green field. This is not new of course, but I like the insight into their software and the presentation. Enjoy! Kick off!
