Detection Confidence 0.35

Min YOLO confidence to register a detection. Lower = more sensitive but more false positives.

Possession Zone — bottom % of frame 55%

Ball center must appear in this bottom portion. Raise (e.g. 70%) if your camera sits higher on your chest.

Min Ball Size — % of frame height 3%

Filters out distant balls. Lower if your camera is further from your feet than usual.

Merge Gap 1.5s

Fuses possession events closer than this, avoiding choppy clips when you briefly lose the ball.

This can take a few minutes for longer recordings.
YOLOv8 is scanning every 3rd frame for possession events.
