The scene UTS North Sydney AWG v Blacktown AWG

Everyone on the field, read off the video with nothing placed or timed by hand: the pitch is found in every over by a model trained on the calibrations marked on this site, every person gets a skeleton, and the moment of each delivery is the bowling arm going over the head at the crease. Roles come from where people stand at that moment — umpire behind the bowler's stumps, striker in his stance, keeper crouched behind him, square-leg umpire standing still — and are voted across the over. The figure on the right is the broadcast camera, where the geometry says it stood.
