UNIQUE REPLAY
Broadcast · Score · Replay
A proprietary platform that turns synchronized field cameras into a full broadcast: computer vision measures every pitch, AI calls it, live boards and burned-in overlays run the show, and instant multi-angle replay puts you inside the play — all from cameras you already have.
◆ LIVE DEMO Running today on a real league — watch the AI pitch tracker measure arc height, flag illegal arcs, and call strike or ball in real time. Open the live tracker →Multi-camera video triangulation
Our headline technology. Synchronized cameras — behind the plate and down the side — watch the same pitch from two angles. Camera geometry turns pixels into true feet, so Unique Replay measures the arc height of every slow-pitch, flags an illegal arc the instant it lands, and calls strike or ball. No sensors on the field. No wearables. No extra hardware for the umpire.
Two synced angles resolve what one camera can only guess
A single behind-plate view trades off depth against height, so an airborne pitch carries about ±1 ft of uncertainty. A second camera down the foul line sees the arc in profile — the two views triangulate the ball's true position in space, tightening arc height toward inches and unlocking a Hawk-Eye-style arc trace. The same rig extends to exit velocity on batted balls.
FT Arc height, in real feet
Tracks the ball frame-by-frame across synced cameras and computes the apex height of the pitch — the number that decides a legal arc — from on-site tape-measured calibration, not a guess.
FLAG Illegal-arc detection
Compares each apex to the legal window and flags a pitch that arcs too high or too flat the moment it crosses the plate.
CALL Strike / ball, automatically
A legal arc landing in the plate box is a strike; otherwise a ball — with the arc trace showing exactly where it came down.
MPH Exit velocity ROADMAP
The same two-camera rig that resolves arc height in profile measures the speed of a batted ball off the bat — next on the build.
From pixels to a call
The same pipeline that runs the live demo — every stage built in-house.
One system runs the whole game
Scoring, replay, broadcast, and analytics — a single connected platform, not a stack of stitched-together tools.
AI Pitch tracking & analytics
Every pitch measured, flagged, and logged — arc height, legal-arc flag, strike/ball, tied to the batter at the plate.
SCORE Live scoring, web & tablet
Score from the stands or the press box on any device, in real time, with the AI keeping the count honest.
REPLAY Instant multi-angle replay
Frame-by-frame, synced across cameras — scrub any play from every angle seconds after it happens.
LIVE Venue boards & overlays
Drive the big screen at the field and burn broadcast-grade score and pitch overlays straight into the video feed.
CAST YouTube live pipeline
An end-to-end broadcast pipeline streams the game live to YouTube with the overlays already baked in.
STATS Auto stats, leaders & standings
Box scores, league leaders, and standings generate themselves from the scored games — no spreadsheets.
RECAP AI game recaps & newsletters
Every game gets an automatic written recap; leagues get AI newsletters that go out on their own.
CAL On-site calibration
A tape-measured field calibration replaces guessed geometry — heights are measured in true feet, per venue.
