The claim, plainly

The NBA's SportVU system captures three-dimensional positional tracking data on every player, the ball, and officials 25 times per second during games.

a quote alone can be ambiguous, so this restates it with the references and context of the conversation around it resolved. AI-written; the tape below the player is the source.

Assessment

The claim bundles several technical assertions about the NBA's SportVU optical tracking system in 2014. The system did indeed track all 10 players on the court, the basketball, and the three game officials at a sampling rate of 25 frames per second (25 Hz). However, the positional tracking data was only three-dimensional (x, y, z) for the basketball; player and referee tracking data was recorded only in two dimensions (x, y court plane coordinates), with the vertical z-coordinate left unmeasured or set to zero.

STATS LLC SportVU technical specifications confirm that optical cameras sampled tracking data at 25 frames per second (25 Hz) for all 10 active players, the 3 referees, and the basketball.
Raw SportVU data feeds and academic technical analyses confirm the basketball was tracked in three dimensions (x, y, z), whereas players and officials were tracked solely via 2D court-plane coordinates (x, y).
