This is the two-camera end-to-end run: the detector swept an entire real game and every candidate it flagged is below in game order. Each clip shows the pitch from both angles at once — the barrel cam behind the plate (left) and the shed side camera (right), cut from the same wall-clock moment. Detection is deliberately loose here, so you are the umpire: confirm ✓ a real pitch, mark a false positive ✗, or fix ✎ the call. Clips play as you scroll; your grades save locally and export to JSON.
