About PitchLab ML Trainer
A clearer view of every pitch.
From video to useful examples
PitchLab ML Trainer is a private workspace for baseball video analysis. It helps coaches and reviewers select a pitch, follow the baseball, correct suggested markings, and prepare checked examples for detector training.
Guidance at every step
The app explains what to do next: upload an original recording, select a pitch, mark the ball in two clear frames, review the suggested trace, and approve examples. Training uses saved batches of reviewed images and labels.
Built for careful review
Automatic traces and model predictions are suggestions. A reviewer checks training labels and compares a new detector before it is selected for use. Initial analysis produces 2D image coordinates; it does not claim calibrated velocity, spin, or movement measurements.
Private access
The workspace is available to approved users through Google sign-in. Public pages explain the product and its data practices. Google integration is being configured; no public registration is available.
