Is the advertising board behind faked then? Shouldn't that be static relative to the finish line, and therefore not really show up?

According to Reddit thread on this, the led board behind is specifically animated with the right timing so the content shows up correctly in the line camera.

There is a special advertising board that only the camera can see.

There's a narrow display behind the finish line with a quickly-scrolling banner ad.

I was there at the time, and I could clearly see how the advertising board works. It's a vertical line of LEDs that constantly rotates through the columns of the logo. To the naked eye it just seems to be flickering randomly.

I was curious what the advertising board would have looked like to the athletes -- it must be a bit distracting to see a display scrolling at ~10m/s! You can see it here at 9m50s: https://youtu.be/7Xnr805bm4E?feature=shared&t=590 https://youtu.be/7Xnr805bm4E?feature=shared&t=590 It's just a single animated strip, one pixel wide. I assume the camera array is on the opposite side.

  It’s weird that it still comes out distorted though. You’d think they’d know the correct rate to play it back at, since they’re the ones capturing it.

    They would need to know beforehand the precise span between the first and last athletes. I think they did a pretty good job, it's only slightly stretched for an event when there was only 0,12 seconds between the first and the last runners, which is unusual.

      I don’t see why the distance between athletes has anything to do with it; they record at a fixed speed which presumably is the estimated speed of the winner crossing the line. So it’s known in advance, and the stretch factor if they get that speed exactly right is 1 anyway. And of course when I say ‘speed’, I mean [width of strip] / [time between the capture of each strip].

    This smells of a cascading dongle tape wrapped and marked "sprints #3"
