Multi-Angle Performance Intelligence

Capture every angle.
Track every change.

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.

01 Where 4DTrack sits

Other systems tell you what happened.
4DTrack shows you the movement behind it.

Ball & result tracking

"Exit velocity was 94 mph."

The number. Precise, and already well served.

4DTrack

"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.

02 How it works

Five steps, one athlete record

Cameras are the capture layer, not the product. Everything downstream is what a coach actually uses.

THE SESSION LOOP 01 Capture 02 Track 03 Measure 04 Analyze 05 Improve

01Capture

Multiple cameras, frame-synchronized, recording every rep automatically.

02Track

Athlete identification and body tracking across every session.

03Measure

Joint movement, timing, position — plus data from sensors you already run.

04Analyze

Technique analysis and side-by-side comparison, assisted but coach-led.

05Improve

Session to session, month to month, the change is on record — and the next session starts the loop again.

03 The part nobody else has

Motion history

One rep tells you very little. The same rep tracked across a season tells you whether the coaching worked.

  • Every session filed under the same athlete, from the first day.
  • Any two sessions compared at the same angle and the same frame.
  • Long-term trends per metric, not a folder of video files.
  • An athlete record that follows the athlete — through the season and beyond it.

04 The judgment layer

Every session ends with a verdict,
not a spreadsheet

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.

05 Inside 4DTrack

From the full roster
to a single frame — four levels

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.

L1/athletes

The board — every athlete, one list

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.

  • One number per row. Best, average, speed and counts all live one level down.
  • Group filters — youth, middle school, adult — and discipline tabs without duplicating rows.
  • Decline is the only thing that shouts: the flagged row is where a coach's time goes first.

L2/athletes/{id}

The athlete page — a season on one screen

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.

  • Growth curve per metric, switched by chips — the layout never moves.
  • Session timeline: one line per session — date, reps, best, and Δ.
  • Goals with progress, and the coach's latest note, live next to the data.
L3/sessions/{n}

The session — today, against last time

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.

  • Highlights are picked automatically: best result, best speed — plus the coach's pick.
  • Every dot on the strip is a rep. Hover for the number, click for the video.

The player — proven in the field for years

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.

06 Built for technique-intensive sports

Not a baseball product

The structure — athlete, discipline, session, rep — is sport-agnostic. Moving to a new sport swaps the metric dictionary, not the product.

Technique drives the result.

02

The same movement is repeated in training.

03

One camera angle is not enough to judge it.

04

Comparing past to present is how coaching happens.

08 FAQ

The questions facilities ask first

Is 4DTrack a baseball product?

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.

Does it replace TrackMan or Rapsodo?

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.

Do coaches have to tag or file anything?

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.

What does an athlete's family get to see?

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.
