Put one play under the physics lens.
Mark the snap, map player movement to the field, and get a readable explanation of speed, separation, leverage, and the Bangel state loop. MJos is the operating system and the predictive model.

FIELD REGISTRATION
Calibrate distance
Pause on a clear frame. Define a visible field rectangle, then click its four corners around the perimeter: origin (0,0), length endpoint (L,0), opposite (L,W), width endpoint (0,W). Length and width follow your selected field axes.
- Origin (0,0)
- Length (L,0)
- Opposite (L,W)
- Width (0,W)
For a sideline angle, use two yard lines ten yards apart and both sidelines when visible. Four ground-plane corners define a perspective homography. Starting a new registration clears all tracks to establish a common origin. Changing dimensions clears calibrated points; review remaining manual coordinates. Camera motion is not detected automatically.

TRACKING
Plot two bodies through time
With calibrated local film: pause, click “Plot current frame,” then click the player’s ground contact point (feet on the field plane). Move to a later frame and repeat. Add at least two points per player.
OR ENTER FIELD COORDINATES
Use one common origin and axes for both players, matching the rectangle above. Coordinates must be inside its dimensions. Blank values are unknown, never zero.Offense track 0
