- AI Swing ReportBeginnerThe AI Swing Report is the report SwingVantage builds after analyzing your video. It leads with the engine's main finding and One Fix, with any optional AI-written coaching layered on top.Analysis Concepts
- AI-Enhanced AnalysisBeginnerAI-Enhanced Analysis is the optional AI layer on top of SwingVantage's rule-based result. It can rephrase the explanation in plainer coaching language, and an AI Vision Review can add a separate second read.Analysis Concepts
- Analysis JobIntermediateAn Analysis Job is the record SwingVantage keeps of each analysis run. It tracks the run's status, such as running, completed or failed, along with timings and a coarse confidence.Analysis Concepts
- BalanceBeginnerBalance is the ability to keep a stable base and a controlled center of mass in a swing. It spans the full motion, from setup through the end of the follow-through.Analysis Concepts
- Baseline MeasurementBeginnerA baseline measurement is the first recorded data point for a metric, captured before training begins, that all future improvement is measured against.Analysis Concepts
- BenchmarkIntermediateA benchmark is a reference value that defines acceptable or optimal performance for a metric; SwingVantage score outputs use one fixed pro grading standard.Analysis Concepts
- Blocked PracticeIntermediateBlocked practice is repeating the same skill or shot in the same conditions many times in a row. It is effective for initial skill acquisition but often less effective for long-term retention than varied practice.Analysis Concepts
- Camera Angle QualityBeginnerCamera angle quality describes how well the recording position lets the system see the relevant joints and movement plane. It is one of the biggest factors you control in analysis accuracy.Analysis Concepts
- Confidence ScoreBeginnerA confidence score rates how much to trust a finding, based on how much good evidence supports it. SwingVantage shows it as a word, such as High, Moderate, or Low, rather than a number.Analysis Concepts
- Consistency ScoreIntermediateA consistency score measures how tightly grouped your metrics are across multiple swings — low variance produces a high score. This is because consistency is often more valuable than peak performance.Analysis Concepts
- Data Source LabelBeginnerA data source label is the word beside a number or result that says where it came from or how it was worked out. It tells you how much weight to give that value.Analysis Concepts
- Deliberate PracticeIntermediateDeliberate practice is focused, feedback-rich work on a specific, diagnosed weakness. Unlike mere repetition or play, it tends to produce faster skill gains per hour of effort.Analysis Concepts
- Deterministic IntelligenceBeginnerDeterministic intelligence is analysis that follows explicit, written rules. The same inputs always produce the same answer, and you can trace exactly why.Analysis Concepts
- Diagnostic ConfidenceBeginnerDiagnostic confidence is how certain SwingVantage is about a finding. It depends on how much data was available and how reliably the pattern appears.Analysis Concepts
- Drill ProgressionIntermediateA drill progression is an ordered series of drills, from slow, controlled, isolated moves to full-speed, game-like play. It follows a common motor-learning approach.Analysis Concepts
- Estimated ValueBeginnerAn estimated value is a number derived from observable cues and encoded rules rather than from direct sensor measurement. A confident, grounded inference that is never presented as a measured fact.Analysis Concepts
- Evidence LabelBeginnerAn evidence label separates what SwingVantage measured with a sensor or launch monitor from what it estimated. Estimates are never shown as lab measurements.Analysis Concepts
- Frame RateIntermediateFrame 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.Analysis Concepts
- Ground Reaction ForceAdvancedGround Reaction Force (GRF) is the force the ground pushes back against an athlete's feet. It is the foundational energy input for the kinematic chain in every swing sport.Analysis Concepts
- Heuristic AnalysisBeginnerHeuristic analysis is smart, rules-and-pattern-based analysis that reads observable cues to surface what is most likely happening in your swing — a confident, data-backed estimate, not a guess.Analysis Concepts
- Heuristic DataIntermediateHeuristic data is a confident estimate, not a measurement. Expert rules of thumb read the inputs and surface the most likely pattern quickly and reliably.Analysis Concepts
- Heuristic EngineIntermediateThe heuristic engine is the deterministic, rules-based part of SwingVantage that runs first on every analysis — no external AI call required.Analysis Concepts
- Improvement DeltaIntermediateAn improvement delta is the measured change in a metric from your baseline to your most recent measurement. It is the hard number behind "did I get better?"Analysis Concepts
- Instant EstimateBeginnerAn Instant Estimate is a fast, rules-only read built from your answers, such as your sport, usual miss and level, without needing a video. It is labeled as a lower-confidence estimate.Analysis Concepts
- Interpreted ValueIntermediateAn interpreted value is a judgment drawn from indirect evidence, like 'likely timing issue' or 'probable hip stall'. It is not a direct measurement, and SwingVantage labels it Inferred.Analysis Concepts
- Kinematic ChainIntermediateThe kinematic chain is the order in which body segments, from the ground up, pass force and speed through a swing. Each segment hands its speed on to the next.Analysis Concepts
- Landmark TrackingIntermediateLandmark tracking follows the position of each detected body keypoint across consecutive video frames. This creates a time-series trajectory for every joint that enables timing and velocity measurements.Analysis Concepts
- Lighting ConditionsBeginnerLighting 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.Analysis Concepts
- Measured ValueBeginnerA measured value comes from a real sensor or instrument, like a launch monitor, radar gun, or wearable. It is not inferred or estimated from video or rules.Analysis Concepts
- Mobile Motion CaptureIntermediateMobile motion capture is the process of using a smartphone camera and on-device pose estimation to track body movement in real time or from a recorded clip — no specialized hardware required.Analysis Concepts
- Mock / Demo DataBeginnerMock or demo data is example data used to show how a feature works, in demos, sample reports and previews. SwingVantage labels it Sample so it is not mistaken for real athlete data.Analysis Concepts
- Motion LabBeginnerMotion Lab is where SwingVantage analyzes your swing video, right in your browser. It tracks your body, grades the clip and leads you to one thing to work on, with a 3D view you can rotate and scrub.Analysis Concepts
- Motor LearningIntermediateMotor learning is the science of how the nervous system learns, refines, and retains skilled movement. It explains how practice actually changes your swing.Analysis Concepts
- Movement SequencingAdvancedMovement sequencing is the timed order in which body segments accelerate and decelerate through a swing — correct sequencing multiplies speed; incorrect sequencing bleeds it.Analysis Concepts
- One-Fix PlanBeginnerThe One-Fix Plan is SwingVantage's core methodology: identify the single highest-impact fault, build a focused practice plan around fixing only that fault, and confirm the fix with a structured retest before moving on.Analysis Concepts
- Outlier in Swing DataIntermediateAn outlier is a data point that falls far outside the normal range for that metric and session. It may represent a genuine extreme swing or a measurement artifact. It requires honest handling before being used in averages.Analysis Concepts
- Phone Video LimitationsBeginnerPhone video limitations are the practical constraints of recording on a smartphone. They can reduce analysis accuracy compared with purpose-built cameras.Analysis Concepts
- Placeholder DataBeginnerPlaceholder data is a stand-in shown where real data is not available yet. SwingVantage labels it so it is never mistaken for a measurement or an estimate.Analysis Concepts
- Player ProfileBeginnerThe Player Profile is the persistent record of an athlete's sport, skill level, swing history, fault patterns, progress metrics, and linked sessions that SwingVantage uses to personalize your coaching and recommendations.Analysis Concepts
- Pose EstimationIntermediatePose estimation is the computer-vision process that detects the positions of major body joints (keypoints) in each video frame. This produces the skeleton that SwingVantage uses to measure angles and movement patterns.Analysis Concepts
- Practice PlanBeginnerA practice plan is a structured, time-blocked schedule of drills and tasks designed to address your diagnosed fault with the right repetitions, feedback cues, and retest protocol.Analysis Concepts
- Practice TransferAdvancedPractice transfer is how much a skill learned in a practice environment carries over to real performance — the ultimate measure of whether your training actually worked.Analysis Concepts
- Primary vs. Secondary FaultIntermediateThe primary fault is the swing issue with the highest severity and impact on performance; the secondary fault is the most likely co-existing issue.Analysis Concepts
- Progress TrackingBeginnerProgress tracking is the longitudinal record of how your key metrics change over multiple sessions and retests, displayed as a timeline that shows improvement, plateaus, and regressions.Analysis Concepts
- Random PracticeIntermediateRandom (or variable) practice mixes skills, shots, or conditions in a session. Studies often find it beats blocked repetition for long-term retention and transfer to real play.Analysis Concepts
- Real / Live DataBeginnerReal data comes from an actual recording, device or session, not from a placeholder or an example. On the source labels, Real marks a value that is a true measurement rather than an estimate or example data.Analysis Concepts
- Recommendation EngineIntermediateThe recommendation engine ranks possible fixes by impact and confidence so you get one high-leverage priority fix — not twenty competing tips.Analysis Concepts
- Recovery SessionIntermediateA recovery session is a low-intensity practice day focused on reinforcing patterns at slow speed, flushing fatigue, and keeping motor grooves active without accumulating more load.Analysis Concepts
- RetestBeginnerA retest is a short follow-up protocol attached to each recommendation. It says how to repeat the test, what to compare, and what success looks like, so you can see whether a fix worked.Analysis Concepts
- Retest DeltaIntermediateA retest delta is the change from your pre-drill baseline to your post-drill retest, on the metric your fix targeted. It shows if one session moved the needle.Analysis Concepts
- Rules EngineIntermediateThe rules engine is the core that checks your shot data and symptoms against sport-specific target windows to find the best-fitting pattern.Analysis Concepts
- Sample SizeIntermediateSample size is how many swings or shots a metric is based on — small samples produce more noise and lower confidence. Larger samples produce more reliable estimates.Analysis Concepts
- SeverityIntermediateSeverity is how much a swing fault is expected to cost you in performance. SwingVantage shows it as a priority label, such as High priority, and Motion Lab adds a Fix or Watch status.Analysis Concepts
- Signal vs NoiseIntermediateSignal is the real, repeatable pattern in your swing data; noise is the random variation that looks like a pattern but isn't. Distinguishing the two is what separates useful analysis from false precision.Analysis Concepts
- Skeleton OverlayBeginnerA skeleton overlay draws your detected body joints, and the lines connecting them, over your video. It shows exactly what the system tracked.Analysis Concepts
- Skill AcquisitionIntermediateSkill acquisition is how practice and feedback make a movement more automatic, consistent, and robust under pressure. It is the goal of all training.Analysis Concepts
- Skill TreeBeginnerThe Skill Tree is a map of a sport's key technical skills. It shows which skills your sessions give evidence for, which are improving, and which come later at your level.Analysis Concepts
- Stability vs MobilityIntermediateStability vs mobility is the principle that joints alternate roles: some are stable anchors, others mobile movers. Faults often come from reversing these roles.Analysis Concepts
- Swing DecodeBeginnerSwing Decode is the contact read inside Motion Lab results. It focuses on the moment of contact and shows the path, plane and timing reads your clip supports.Analysis Concepts
- TempoBeginnerTempo is the timing relationship between the two halves of a swing — the rhythm that separates efficient, repeatable mechanics from a rushed or laboured transition.Analysis Concepts
