#2 is important but has a spatial problem for football. A basketball court is much smaller and would allow for wide shots to still include the details of a ball leaving a shooter's hand or contact. Does a football field's size negate that? IDK
Couple thoughts…
1. Multiple leagues are allowing these reviews (audio and video)to be aired live after ACC broke the seal last year. Much of this dialogue goes away if no discrepancy between TV interpretation and what replay refs actually decided. Shows power of that access.
2. Basketball has already solved this problem. Add tenths of a second to clock in last minute and have a backboard light as frame of reference to true zero.
3. Why is that reference light so powerful? Any clock as a separate source in 2-box (like B10 released) is dependent on an accurate synchronization of those 2 sources. People rightfully asking, how do I know that clock camera is in sync as WM player is touching the ball? Nothing obvious in this video to tether those 2 sources together. We just have to take their word for it. I have produced plenty of shows where syncing one camera or another was troubleshot throughout game. Doesn’t mean it happened here, but it is possible.
Wide shot with a light to show true zero in frame of play? Much simpler.
4. As for what was shown on TV…Any video source (clock in this case) layered on top of another via digital video effect (DVE) has potential to be delayed by fractions of a second. It takes time, all be it very small, for video sources to move around in a production router where they are mixed together by the video switcher. There are plenty of instances where a basketball final second shot shows time on the DVE clock (what TV showed in lower corner) while light and physical clock in frame of camera shot have already hit zero. It may only be a difference of a frame of video (usually 1/30th of a second) but plenty of sports moments prove to be that close. The data feed that powers the virtual “bug” with clock and score can have similar lag. Thus the power of the light.
If football puts a light on the goalposts and/or some other place at field level, nearly all the ambiguity of this instance goes away. Will be interesting to see if this lightning strike moment brings any change or just gets swept away in the flow of the season as such tech would take investment for far fewer close moments than in hoops.
