Video Quality Score
Also known as: VQS, clip quality score
A Video Quality Score is a pre-analysis rating (0–100) that tells you how usable a submitted clip is before pose estimation begins — catching bad angles, motion blur, or poor lighting early.
Before committing to a full analysis, SwingVantage runs a fast, device-side quality check on your video. It judges frame rate, lighting, camera angle, whether the full body is in frame, and whether motion blur is acceptable. A score below a threshold triggers a plain-English warning explaining what to fix, so you are not waiting for analysis only to get a low-confidence result. Passing the gate is an honest prerequisite: the score tells you the clip is worth analyzing, not that the analysis will be perfect.
Example
A clip recorded against bright window light scores 38/100 — the gate flags "backlit subject" and suggests moving outdoors or repositioning.
Why it matters
Garbage-in, garbage-out is the most common source of bad AI analysis. The quality gate catches the problem upfront instead of letting it silently degrade your report.
Frequently asked questions
Does a low Video Quality Score mean my swing is bad?
No — it means the video itself is hard to analyze. Your swing may be fine; the clip just needs better conditions.
Can I still get an analysis with a low score?
You can try, but SwingVantage will warn you that confidence will be lower than usual and label any estimates accordingly.

- Camera Angle QualityCamera angle quality describes how well the recording position allows the system to see the relevant joints and movement plane — the single biggest controllable factor in analysis accuracy.
- Lighting ConditionsLighting conditions describe how evenly and brightly the subject is illuminated — poor lighting is one of the top causes of low-quality video and degraded pose estimation.
- Video Quality GateThe Video Quality Gate is the automatic pre-analysis check that evaluates a submitted clip's usability and blocks or warns before processing video that is too low-quality to produce reliable analysis.
- Pose EstimationPose estimation is the computer-vision process that detects the positions of major body joints (keypoints) in each video frame, producing the skeleton that SwingVantage uses to measure angles and movement patterns.
- Frame RateFrame rate (frames per second, fps) is how many individual images your camera captures each second — higher frame rates freeze fast motion better and produce more reliable pose tracking.
