Eight Analysis Tools
Frame-accurate. Coach-driven.
Built for surfers.
01
Frame-by-Frame Markup
Your coach isolates any frame in your session video and draws directly on it — arrows, circles, trajectory lines, body-position markers. Every micro-movement analysed frame by frame, not guesswork.
02
Voice Commentary Overlay
Your coach records time-coded voice commentary that plays back over your video. Hear exactly what you were doing wrong the moment it happens. Pause. Rewind. Internalise. No reading — just listening and learning.
03
Side-by-Side Comparison
Place your wave next to a reference wave — a pro, your coach, or your own best ride. Synchronised playback at the same speed. See the difference in line, timing, and body position with surgical precision.
04
Slow-Motion & Freeze-Frame
Slow your wave down to 0.25x speed. Freeze at any point. Your coach pins timestamped text notes directly onto the timeline so you never lose the moment that matters. Frame-accurate coaching.
05
Angle Overlay Grid
Overlay a coaching grid onto your video — posture alignment, rail angle, shoulder rotation, head position. Your coach lines up the grid with your body and shows you exactly where your alignment breaks down.
06
One-Click Coach Share
Upload a session clip from your camera roll, tag your coach, and it lands in their Kaizen Lab queue instantly. No email, no file transfer, no compression. Your coach opens it in the Lab and gets to work.
07
Before / After Timeline
Kaizen Lab archives every analysis you've ever received. Scroll back through your timeline and watch your progression as a video story — from your first pop-up critique to your latest barrel entry breakdown.
08
Export & Download
Download every analysed video with all markups burned in. Keep your coaching history locally, share it with a private coach, or post your before/after transformation. Full-res, no watermark.
Next-Level Analysis
Biomechanical Profiling.
Built for Surfers.
Beyond video analysis, Kaizen Lab captures biomechanical data that reveals how your body moves through every phase of a wave. Charts are generated from your session footage and coach assessments — stored, tracked, and benchmarked against your own history.
This is surf-specific body intelligence: joint angles, rotation timing, weight distribution, paddle symmetry, pop-up dynamics. No generic sports science — every metric is calibrated for the demands of surfing.
Joint Angles
Shoulder, hip, knee alignment at take-off, bottom turn, and cutback
Rotation Timing
Degrees per second through each manoeuvre phase
Benchmarking
Compare your metrics session-over-session, month-over-month
Body Mapping
Weight distribution, paddle symmetry, pop-up explosiveness
Biomechanical Analysis Dashboard
Movement Decomposition
Every manoeuvre broken into phases — approach, initiation, apex, exit. Each phase measured for angle, timing, and body position. Your coach sees the micro-movements you miss.
Historical Benchmarking
All your biomechanical data stored and trended. Watch your pop-up time drop, your rotation angle increase, your paddle symmetry balance. Progress you can see in the numbers.
Coach-Driven Prescription
When a metric plateaus, your coach prescribes a targeted drill. Not generic advice — a specific intervention tied to a specific number. That is next-level coaching.
