Video input
Use demo footage, upload a pitch, or record a new sequence from the app.
Private desktop beta
Kinatrix
Baseball pitching biomechanics from video: pose detection, 3D reconstruction, smoothing, and movement curves built for reviewing pitch sequences.

What it does
Turn a pitching video into reviewable biomechanics.
Pose and 3D
The pipeline detects the pitcher, estimates 2D pose, reconstructs 3D motion, and smooths the sequence.
20+ metrics
Review kinematic sequence, pelvis rotation, trunk tilt, shoulder motion, elbow flexion, COG, and more.
Saved analysis
Completed pitch analyses can be saved locally by account for beta review and later comparison.
Workflow
From video to curves.
The input screen stays clean and shows only the raw video. After analysis, the summary view shows biomechanics playback with the rendered visualization, synchronized plots, and collapsible metric categories.
-
01
Select a pitch
Choose demo footage, upload a file, or record a new pitch sequence.
-
02
Run analysis
Detection, crop prep, 2D pose, 3D pose, smoothing, and biomechanics metrics run through the backend pipeline.
-
03
Review results
Scrub the playback and see pitch curves update by frame across each metric category.
Install
Mac desktop beta.
The Mac app includes the Kinatrix interface, local backend, beta sign-in, analysis history, and bundled video tooling. GPU-heavy processing can be configured to run on the H100 VM for beta systems.
Download available by inviteThe public download link is added when the beta binary is hosted.
1
Download the Kinatrix Mac app from your invite link.
2
Open the app, then sign in with the beta credentials from your invite.
3
Run demo analysis or process a pitch video when compute is configured.
For beta partners
What is local today.
Local app data
Accounts, saved analyses, uploads, and logs are stored on the Mac during the desktop beta.
Compute path
Demo results can run locally from stored outputs. Real GPU analysis needs the configured CV runtime or H100 VM bridge.
Performance use only
Kinatrix supports coaching, motion analysis, and performance evaluation. It is not a medical device and does not diagnose injuries.
Internal testing
Beta runs are reviewed through an admin console.
User portal
Test users submit baseball or softball video, choose whether the video is already cut, and view saved reports after analysis is complete.
Admin review
Admins can see active runs, saved report history, long-video approvals, expert-review requests, backend readiness, interrupted jobs, and failed-run retry controls.
Feedback notes
Expert or coaching notes can be saved onto a completed report before sharing it back with the athlete or partner.
Outside review
The admin console can draft an email to a coach or expert with the run summary, notes, and available review link.
FAQ
Common setup questions.
Does the Mac app need a terminal?
No. The packaged desktop app starts its backend automatically.
Where is data stored?
Desktop beta data is stored under macOS Application Support for Kinatrix.
Can users run real analysis without the VM?
Only if the local machine has the full CV runtime, weights, and compatible compute. The beta path is to configure remote H100 processing.
Is this the iPhone app?
No. This is the desktop beta path. iPhone and App Store work come later after cloud storage, auth, payments, and GPU provider decisions are finalized.
