Baseball swing preview

One priority and one drill from a side-view phone clip. Film from the opposite batter's box, chest-facing. Estimates only — not validated coaching.

A development preview of how Swing Lab will read a baseball swing from a side-view clip. Locked phases, experimental 2D development values, one priority and one drill. Estimates only — not validated coaching, and not a performance report.

DEVELOPMENT PREVIEW · ESTIMATES ONLY

Start with how to film

  • Founder Beta development preview — experimental, not validated coaching.
  • Single-camera projected 2D estimates only. Not calibrated 3D truth.
  • No launch-monitor numbers or accuracy claims.
  • No performance, ranking, or instruction-ready conclusions.
  • Side-view development values against your own baseline. Not a 3D lab report.

Example — not real data

Example — not real data

Illustrative layout only. Numbers and the priority below are made up so you can see the report shape.

Your front knee keeps bending after you plant. (example)

Drill: Pause at plant, brace the front leg, then turn. (example)

A firm front leg helps you turn through the ball.

Locked phases

Customer-facing order is locked: Stance, Load, Stride, Swing, Contact, Follow-Through. Event anchors in this preview are loadComplete, footPlant, and contact.

  1. 01Stance

    Athletic base, balance, and posture before the pitch.

  2. 02Load

    Store energy into the back hip before the forward move.

  3. 03Stride

    Timing, linear momentum, and a controlled landing.

  4. 04Swing

    Brace the front side and rotate after plant.

  5. 05Contact

    Energy transfer into a firm front side.

  6. 06Follow-Through

    Deceleration and a balanced follow-through.

What is measured

Side-view 2D development values only. Hip-shoulder separation and sequence stay unavailable. Nothing here is a 3D lab pass/fail.

  • Front-knee angle at plantDevelopment preview

    Lead hip-knee-ankle angle at foot plant. 2D development value, not a 3D lab norm.

  • Front-knee minimum after plantDevelopment preview

    Minimum lead-knee angle between foot plant and contact.

  • Front-knee braceDevelopment preview

    Change in lead-knee angle from the post-plant minimum (and from plant) to contact.

  • Front-knee brace rateDevelopment preview

    Angle change per second after the post-plant minimum. Angle proxy for lead-leg force, uncalibrated.

  • StrideDevelopment preview

    Lead-ankle travel from its rearmost position before plant to plant, divided by torso length. Window-start to plant is stored alongside it.

  • Hip-midpoint shiftDevelopment preview

    Mid-hip travel, load to plant and plant to contact, divided by torso length.

  • Head driftDevelopment preview

    Nose travel from load complete to contact, divided by torso length.

  • Hip-shoulder separationUnavailable

    Permanently unavailable from side view. No numeric field.

  • Sequence orderUnavailable

    Permanently unavailable from side view. No numeric field.

Softball uses the same locked phases and side-view formulas in this Founder Beta. Softball norms not sourced. Bat and ball differences are notes, not calibrated measurements.
