What camera angle should I use? +
The 45-degree referee angle — positioned diagonally from the end of the bench at roughly bench height — gives the most accurate rule adherence assessment. This is the same angle a WPP head referee sits at in competition, giving a clear view of elbow lockout, pause quality, and chest contact simultaneously. Side-on is useful for bar path and velocity but cannot reliably assess simultaneous lockout.
How accurate is the AI analysis? +
RefLight is a coaching and preparation tool, not a replacement for a qualified referee or coach. AI analysis can and does make errors — scores and verdicts should be treated as directional guidance, not definitive judgements. Always use RefLight output alongside qualified coaching and your own technical knowledge, and never as a sole basis for competition decisions. The velocity estimate is an AI visual approximation from video frames, not a calibrated measurement, and should be used with caution. Accuracy depends on video quality, camera angle, and lighting conditions.
Can I edit the analysis output? +
Yes — every line of the analysis output is editable directly in the app before you export. Coaches can adjust the language, add context, or personalise the feedback for each athlete. Athletes can annotate their own sessions. The exported PDF reflects whatever edits you make.
Does RefLight cover IPF able-bodied powerlifting? +
RefLight currently focuses on World Para Powerlifting (WPP) rules for para powerlifting bench press. IPF able-bodied analysis covering squat, bench press, and deadlift is on the roadmap.
What happens to my video after analysis? +
Your video is uploaded to our server for processing, key frames are extracted for analysis, and the video file is deleted immediately after frame extraction. We never store your video permanently. Frame data is used for analysis only and is not retained after your report is generated.
Do credits expire? +
No. Credits never expire. Buy a pack when you need it and use them at your own pace — across a competition prep block, a full season, or across multiple athletes.
What video formats are supported? +
RefLight accepts MP4 and MOV files, which covers all modern smartphones. Single rep clips work best — ideally 10-30 seconds covering the full lift from setup to rack.
How do I buy credits? +
Create a free account first at ref-light.co.uk, then purchase your credit pack inside the app. Credits are added to your account instantly on payment via Stripe. We offer three packs — Starter (10 analyses, £15), Training Block (30 analyses, £35), and Squad (100 analyses, £99). Credits never expire.
What is the side-on camera angle used for? +
The side-on angle is specifically for bar path and bar velocity analysis. From this angle, RefLight assesses descent control, concentric bar path trajectory, and estimates bar velocity. It cannot assess pause quality, elbow lockout, chest contact, or pressing symmetry — these require a 45-degree or front angle. If you select side-on, your report will focus exclusively on bar path and descent mechanics rather than WPP rule adherence.
How large can my video file be? +
For best results, film in standard HD (1080p) rather than 4K. Very large files — typically 4K footage over 5MB — may exceed processing limits and return an error. A 3-10 second single rep clip filmed in standard HD will typically be 1-4MB and works reliably. If you experience a file size error, try reducing your camera resolution in settings before filming.
