Gizmodo posted a video from FanDome last week about the incredibly complicated process of placing the yellow “first down” line on a football field during live coverage of a football game. I never gave the yellow line much thought since it never seemed like it could be much more than just alignment, but as it turns out, there’s a lot of manpower and computer-power that goes into making that yellow line look as good as it does. Things like color adjustments and camera angles and alignment are just the tip of the iceberg for technical crews working to make watching football a bit easier and more understandable to the average TV viewer.
