PUMPFOIL LABS / SOFTWAREBUILT FOR macOS. PROCESSED LOCALLY.
THE FEELING. THE PATTERN. THE DIFFERENCE.

From the movement you feel
to the patterns you can see.

SCROLL TO EXPLORE
01 — THE IDEA

A pump happens fast.
Understanding it
takes a closer look.

There’s a lot happening between the push and the return. Your knees extend. Your hips move. The next cycle begins.

Pumpfoil Labs puts two clips in one focused Mac workspace—so you can stop chasing the playhead and start seeing the movement.

02 — EXPLORE THE SOFTWARE

EVERY DETAIL.
OUT IN THE OPEN.

Scroll through the tools.
Find the difference you can feel.

01 / FRONT + SIDE POSE

FRONT. SIDE.
YOUR NEXT INSIGHT.

See front and side views of reconstructed movement. Match rider size, overlay both skeletons, and rotate a shared camera to inspect lean, knee motion, and torso twist.

Experimental 3DFront + side viewsMatch size + overlay

Reconstructed 3D is experimental. Image fit does not establish depth accuracy.

FRONT
SIDE

Same riders. Shared camera. Match size, flip, and normalize heading.

02 / LIVE MOVEMENT CHARTS

FOLLOW THE POSE.
READ THE CURVES.

Watch knee angle, hip angle, and torso lean change alongside the footage. Live A/B values and curves follow the actual pumps you selected.

Live A/B curves follow your selected loops.

03 / PHASE-MATCHED PLAYBACK

TWO RIDERS.
ONE RHYTHM.

Find the same part of every pump. Synchronized, complete-cycle loops bring extension, compression, and return into focus. Switch to original timing to see the cadence difference.

Compare complete pumps, then switch to original timing to see the difference in rhythm.

04 / FOOT PLACEMENT

YOUR STANCE.
IN PERSPECTIVE.

Mark the board, mast, and foot contacts. Align both stances at the mast to compare foot placement, stance width, and an optional estimated shoulder-width reference.

03 — FROM FOOTAGE TO INSIGHTYOUR FIRST FIVE MINUTES

Bring two clips.
Find your next question.

01

Load your footage.

Add two videos. Compare yourself with an earlier run or study an expert. Run local pose analysis.

02

Find a clean pass.

Choose several clear pumps from a similar camera angle. Check source timing for slow-motion exports.

03

Loop. Look. Compare.

Match pump phase. Slow things down. Switch between video, skeleton, and overlay to follow the differences.

04

Return to the evidence.

Open measurements, then check the original footage. Make sure the estimated joints actually follow the rider.

THE WHOLE
PICTURE.

From paired video to shared 3D.
A quick tour of the review workspace.

05 — BUILT WITH CURIOSITY

Useful evidence.
Honest limits.

01

Local by design.

Video processing and pose estimation run on your Mac. No video-analysis subscription or API key is needed.

02

One app, from video to 3D.

Review footage, compare 2D pose, and explore reconstructed 3D in the same workspace. One user guide covers the complete workflow.

03

Evidence you can inspect.

Camera perspective still matters. 3D is experimental. The app does not measure force, power, foot pressure, or an ideal technique.
