The flow

Capture. Break down. Send home.

Three screens, one session. The phone watches; the breakdown reads the form; the highlight clip lands in the family portal before the kid is off the floor.

STEP 01 · CAPTURE · BASEBALL
9:41
Live · on-device

Apple Vision runs per-frame. Pose + trajectory + classifier confidence stream into a 3-second ring buffer.

STEP 02 · BREAKDOWN · BASEBALL
9:41
A swing, broken down.

Bat speed, attack angle, contact point. Spray chart updates with every cage rep.

STEP 03 · OUTCOME · BASEBALL
9:41
Highlight + score

Auto-edited 8-second clip with the verdict overlay. Sharing is opt-in per clip.

Capture spec

How baseball is captured.

Every sport has a tuned capture loop. Here's exactly what runs and what comes out.

Frame rate
120 fps cage · 240 fps for impact analysis
Field of view
Down-the-line · single batter · open or closed cage
Ring buffer
2 s · 240 frames · centered on contact
Apple framework
VNDetectHumanBodyPoseRequest + custom CoreML
Compute
Apple Neural Engine · on-device only
events emitted
swing_attempt
contact_event (bat-ball impact frame)
spray_outcome (estimated landing zone)
v1 caveats
Cage netting can confuse trajectory — calibrate net plane
Estimated landing zone only — not full ball tracking
Pipeline

Frame → event → portal.

Six stages, all on-device until the highlight clip — and that only leaves the phone if the family says yes.

  1. step 01
    AVCaptureSession
    Tee the buffer · live analyzer + record
  2. step 02
    VNImageRequestHandler
    Run pose + trajectory on a serial queue
  3. step 03
    Ring buffer · 3 s
    Backread for release frame on confirm
  4. step 04
    CoreML classifier
    Per-sport model emits the event + confidence
  5. step 05
    Auto-edit · 8 s clip
    Around the apex frame, verdict overlay
  6. step 06
    Family portal sync
    Drop the clip + event into shared.* on opt-in
