Designed for visible 2D movement
Use a calibrated side-view recording or still image to examine joint positions, segment motion, distances, and trajectories.

Browser-based movement analysis
Turn ordinary video into reviewable movement data.
Measure, track, annotate, and compare human movement frame by frame—without installing desktop analysis software.

Product overview
What MotionLab is built to do
Clear product boundaries are part of the design: capability, evidence, and current maturity are stated separately.
Measurements stay inspectable
Analysts can review frames, correct tracked points, and retain the method context needed to understand an output.
Built for technical review
The workspace brings media, markers, measurements, graphs, annotations, and exports into one browser workflow.
Workflow
From source evidence to a reviewable result
- 01
Open
Load a local video or image into the browser workspace.
- 02
Calibrate
Define a known distance; use four-point plane calibration when the camera is not square to the movement plane.
- 03
Measure
Place markers, define body segments, measure angles, and add technical annotations.
- 04
Track
Follow landmarks through frames and manually correct any estimate that needs review.
- 05
Analyse
Inspect trajectories and graphs, then export data, figures, annotated frames, or reports.
Capabilities
A focused professional toolset
Each capability supports the product's defined workflow; none is presented as a substitute for qualified review.
Frame navigation
Transport controls, a timeline, and keyboard shortcuts support close temporal review.
Spatial calibration
One-dimensional and four-point plane calibration support measurements in a defined image plane.
Marker tracking
Pixel tracking remains the primary path; local pose models can seed correctable landmark estimates.
Movement graphs
Review marker coordinates, joint angles, trajectories, and range summaries across a selected interval.
Comparison workspace
Pro workflows can align two to four local videos or images for synchronized review.
Professional exports
Create CSV data, publication figures, annotated frames, and HTML/PDF-ready reports with methods metadata.
Product interface
The work stays connected to its context
Current MotionLab interface views.
Analysis workspace
Media, tracked landmarks, measurements, timeline, and plots remain visible in one review surface.
Frame-level measurement
Inspect and correct the points behind each angle or trajectory.
Kinematic review
Compare movement traces without separating the plot from its source context.
Example outputs
Outputs designed to be reviewed—not merely generated
Coordinate and measurement tables

Publication-ready visuals
Export graphs and annotated frames for technical communication.
Reviewable analysis summary

Privacy and data handling
Know where the evidence goes.
- Source videos and images are decoded and analyzed on the device.
- Optional account sync stores project JSON—not source media.
- Project payloads reject embedded media data and are capped by the application.
- Payment-card data is handled by Stripe and is not stored by MotionLab.
Validation
Method transparency—not a blanket accuracy claimEvidence has boundaries.
MotionLab includes deterministic regression fixtures and documents tracking behavior, provenance, and known limitations. The current evidence does not establish universal accuracy for arbitrary recordings.
- AI-assisted positions are labelled as estimates and remain correctable.
- Large rotation, blur, deformation, scale change, and out-of-plane motion can require manual correction.
- Protocol-specific use should be validated against independently digitized recordings.

Frequently asked questions
Technical questions deserve direct answers
Does MotionLab upload my videos?
No. Source media is processed on your device. Optional sync stores project JSON, which can include calibration, coordinates, measurements, and settings, but not the source video.
Is this a replacement for 3D motion capture?
No. MotionLab is a two-dimensional, video-based analysis workspace. It does not turn monocular video into validated 3D motion capture.
Can I correct automatic tracking?
Yes. Pose assistance seeds estimates; analysts can review and correct points. Low-confidence or invalid landmarks are left as gaps rather than accepted as measurements.
Which browser should I use?
Use a current desktop browser. MP4 with H.264 is the most broadly supported video choice; specific codec support depends on the browser and operating system.
Can MotionLab be used for clinical decisions?
MotionLab provides measurement and documentation tools. Suitability for a protocol, population, or decision remains the responsibility of qualified users and requires appropriate validation.
