4DTrack captures athlete movement from synchronized multiple angles and builds a motion history that helps coaches measure, compare, and improve performance over time.
Built on the multi-camera technology 4DReplay has run in live broadcast for over a decade.
The 4DReplay heritage — the foundation 4DTrack stands on
"Exit velocity was 94 mph."
The number. Precise, and already well served.
"Here is the hip rotation, weight transfer and bat path that produced it — and how each one changed across the season."
The movement, from every angle, across every session.
We do not replace TrackMan or Rapsodo. Facilities already running them are our best fit — 4DTrack explains the numbers those systems produce.
Cameras are the capture layer, not the product. Everything downstream is what a coach actually uses.
Multiple cameras, frame-synchronized, recording every rep automatically.
Athlete identification and body tracking across every session.
Joint movement, timing, position — plus data from sensors you already run.
Technique analysis and side-by-side comparison, assisted but coach-led.
Session to session, month to month, the change is on record — and the next session starts the loop again.
One rep tells you very little. The same rep tracked across a season tells you whether the coaching worked.
Each session closes with a single score, the change against the previous session, and one sentence a coach would actually say. Raw numbers stay one click below — the list view never makes you do the math.
"Hip rotation is firing earlier. Next session starts with lower-half drills."
"Chasing velocity rushed the delivery. Next two sessions: radar gun covered, command only."
Goals live next to the data — progress bars in state colors, judgment at a glance.
The product follows how coaching actually flows: who needs you first, how that athlete is trending, what happened today, and the one rep that proves it. Every level links to the next.
Sorted by who needs you first. One row per athlete — never split by discipline — with their latest session, a 12-session trend line, and a single Δ against last time. Athletes falling behind carry a flag you can't miss.
"Hip rotation is firing earlier. Next session starts with lower-half drills."
The screen a coach opens in a parent meeting. The hero is not today's video — it is the growth curve: session 1 to session 12, one line. Each discipline gets its own tab and its own chart, because distance and velocity never share an axis. The athlete stays whole: one page, however many disciplines they train.
A session opens on its verdict, then proves it: last session's best next to today's, same angle, frame-synced, with the numbers that moved. Below, every rep sits on one strip — the rhythm of the whole session at a glance.
The multi-angle player our broadcast clients have used for a decade: rotate around the athlete, slow the motion down, snap a frame, draw on it. In 4DTrack it keeps its place in the record — previous and next follow the session's rep order, and the session is one click up.
One read-only link from the coach: the growth curve, the highlight clips, the coach's note. No login, no other athletes, phone-first. For an academy, this is the screen that re-enrolls.
Session and monthly reports assembled from the same record: growth curve, highlights, the numbers that moved, and the coach's own summary. Web view, PDF, or a share link.
The structure — athlete, discipline, session, rep — is sport-agnostic. Moving to a new sport swaps the metric dictionary, not the product.
| Sport | A rep is… | Disciplines per athlete | Headline metrics |
|---|---|---|---|
| Baseball | one swing / one pitch | hitting · pitching | distance, bat speed / velocity, strike% |
| Gymnastics | one routine attempt | vault · bars · beam · floor | execution & difficulty |
| Golf | one shot | swing | carry distance, club speed |
| Snowboard / Ski | one run, one trick | halfpipe · slopestyle | air, rotation, landing |
| Team drills | one stop, one drill | crew positions | drill time by position |
Technique drives the result.
The same movement is repeated in training.
One camera angle is not enough to judge it.
Comparing past to present is how coaching happens.
Used by coaches, athletes, performance directors and sports scientists. 4DTrack is not a parent or fan app — but the progress it records is what parents come to see.
No. Baseball hitting and pitching are where we run today, but the structure — athlete, discipline, session, rep — is sport-agnostic. Any sport where technique decides the outcome and one camera angle can't settle the question fits: gymnastics, golf, snowboard, figure skating, diving, and more.
No — and it isn't meant to. Result trackers tell you the number; 4DTrack shows you the movement that produced it, from every angle, across every session. Facilities already running result trackers are our best fit.
No. The cameras record every rep automatically, and every session is filed under the same athlete from the first day. The coach's job stays coaching — the record keeps itself.
Exactly what the coach shares: a read-only link with the growth curve, highlight clips, and the coach's note. No login, no access to other athletes, built for a phone.
