Video Motion Analysis
Analyze videos with AI-powered assessment tools
AI is used to analyse movement videos
EZCap uses AI to estimate body or hand landmarks and movement measurements from video. Results are estimates that may be affected by camera position, lighting, and tracking errors. They are not a medical diagnosis and do not replace clinician judgement.
How the analysis works, what is kept, and your rights
AI model and execution
Loading the selected model and device compute details…
Video frames are analysed in this browser on your device. EZCap does not upload your video, frames, landmarks, or analysis results to its servers for AI processing. Model libraries and model files are downloaded from third-party CDNs; those services receive normal network request information, not your video frames.
Storage and retention
Video and analysis data stay in this browser's session and are cleared when you reset the analysis or leave the page. EZCap does not keep a server copy. Files you export are saved to your device; you control how long those copies are kept. Theme and CSV export preferences may remain in this browser's local storage until you clear them. Website analytics are separate from video analysis: the privacy policy lists 90 days for usage and technical data, 180 days for performance metrics, and 30 days for IP-derived location data.
Participant consent
Before recording or analysing someone else, explain how the video will be used and obtain their informed consent. For anyone under 16, obtain parent or guardian consent. Research and clinical use must also follow applicable ethics approval, consent, and institutional requirements.
Your privacy rights
The privacy policy describes rights that may apply, including access, correction, erasure, restriction, portability, objection, and withdrawal of consent. For personal-data requests, contact the University of Essex Data Protection Officer at dataprotect@essex.ac.uk. Because videos and results are not sent to EZCap, we cannot retrieve or erase copies you have exported to your device.
Read the notice and confirm both items before starting analysis. These confirmations are not saved after you leave this page.
