A systematic video self-coaching protocol that keeps you developing between coaching sessions — with the right angles, the right checkpoints, and a structured review process that turns footage into actionable change.
Feel is an unreliable guide to improvement. Every Tour player uses video because the human brain's proprioceptive system systematically distorts perception of movement — what you feel you are doing and what you are actually doing are often dramatically different.
"Every significant change I've ever made to my swing came from seeing it on video first. Feeling alone got me nowhere."
— Rory McIlroy, on his use of video coaching
The Proprioceptive Distortion Problem
Why Feel Misleads You
Research by Dr. Rob Neal (Golf Biodynamics) demonstrates that amateur golfers perceive their swing to be significantly more on-plane, more face-square, and more centred than video measurement confirms. The brain learns to feel what it expects — not what is happening. A face that is 8° open at impact feels square to a golfer who has always played with an open face. Video removes this distortion entirely.
What Players Feel
Subjective Reality
Swing feels on-plane, face feels square, turn feels full. This is the proprioceptive signal — well-intentioned but unreliable for detecting pattern deviations under 10°.
What Video Shows
Objective Reality
Club is over-the-top, face is 6° open, hip turn is restricted. The camera records what the nervous system cannot accurately report — this is the gap video coaching closes.
The Inter-Session Coaching Problem
What Happens in 12 Weeks Without Video
Your coaching programme specifies quarterly swing audits with a TPI-certified coach. That leaves 12 weeks between sessions. Without video self-monitoring, three things routinely happen:
1
New patterns drift without correction. A change introduced in a coaching session begins to revert within 2–4 weeks as old motor patterns re-emerge. Video catches this before 12 weeks of practice reinforces the reversion.
2
Compensations develop undetected. Players who work on one fault often unconsciously introduce a compensatory move elsewhere. Video identifies the compensation early — a coach seeing you after 12 weeks sees a more complex problem than the original fault.
3
Coaching session efficiency drops. A coach who receives video footage from you every 2–3 weeks can guide your inter-session work specifically. A coach who sees you only live has to spend 30 minutes diagnosing what they could have seen in 3 minutes of footage sent in advance.
🎯
The self-coaching limit: Video self-coaching is powerful — but it has a ceiling. It is best used to monitor the specific changes your coach has prescribed, detect drift and regression, and prepare intelligent questions for your next session. It should not be used to diagnose and self-prescribe new swing changes without coach guidance. The risk of misdiagnosis is high and the cost is wasted practice time.
Camera Setup — Getting It Right
Incorrect camera placement produces misleading footage that cannot be analysed accurately. The setup is simple but non-negotiable — small errors in position or height produce large distortions in apparent swing plane, face angle, and path.
📐 The Two Essential Angles
Primary Camera Positions — Both Required for Complete Analysis
📹
Down the Line (DTL)
Camera behind the player, along the target line. Shows swing plane, club path, face angle, spine angle, and hip-shoulder separation.
Behind player · Hand height · On target line
📷
Face On (FO)
Camera facing the player from directly in front. Shows weight transfer, lateral sway, head movement, spine tilt, and low point position.
Facing player · Hand height · On ball line
Down-the-Line Setup — Precise Specifications
Position Your Camera Exactly
1
Distance: 8–12 feet directly behind the ball, exactly on the target line. Use an alignment stick on the ground pointing at the target — your camera should be on this exact line extended behind you.
2
Height: Hand height — approximately waist to mid-torso height (roughly 36–42 inches for most golfers). This aligns the camera lens with the hands at address. Too low produces a misleadingly flat plane; too high produces a misleadingly steep plane.
3
Angle: The camera should be level — no upward or downward tilt. The ball should appear in the lower third of the frame with the player's full body visible from feet to top of backswing.
4
Zoom: Frame the player so the full body is visible with a few feet of space on all sides. Do not zoom in on the hands — you need the full swing arc in frame.
5
Verification: In the frame at address, your club shaft should appear to point through your trail forearm when viewed DTL. If it doesn't, the camera is off the target line.
Face-On Setup — Precise Specifications
Position Your Camera Exactly
1
Distance: 8–12 feet directly in front of the player, on a line through the ball perpendicular to the target line. Place an alignment stick perpendicular to the target to ensure correct positioning.
2
Height: Same as DTL — hand height (36–42 inches). Consistent height between both angles allows meaningful comparison.
3
Angle: Camera level, not tilted. At address, the player's sternum should be centred in the frame. The full body from feet to above the hands at the top of the backswing must be visible.
4
Common error: Setting up off-centre (to the lead or trail side). The camera must be on the line through the ball. Even 2 feet of lateral offset distorts the appearance of head movement and weight transfer significantly.

Practical tip: Most modern driving ranges have slightly uneven ground and varying light conditions. Arrive 5 minutes early to set up and film a single test shot before your session. Review the frame — confirm full body is visible, camera is level, and the ball appears at the correct position in frame. Adjust once before beginning analysis shots.
Down-the-Line Analysis
The DTL view is the primary diagnostic angle for swing plane, club path, face angle, and the relationship between body segments at each key position. These are the checkpoints used by every PGA Tour coach on every session.
🔎 The Six DTL Checkpoints
P1 — Address
Setup Fundamentals
Pause on the address position. Use draw lines in your app to check:
▸
Shaft angle: Draw a line through the club shaft. It should point through the trail forearm (not below the elbow, not above it). Shaft pointing through the belt buckle = too upright; through the knee = too flat.
▸
Spine angle: Draw a line through the spine. Healthy address spine angle is 30–40° from vertical for a full iron shot. Excessive or insufficient tilt is the root cause of several common compensations.
▸
Ball position: From DTL, confirm the ball is on the target line — not inside or outside. Consistent ball position is the foundation of consistent low point.
▸
Weight distribution: From DTL, check the knee flex. Lead knee should be slightly flexed and stable — not locked or excessively bent. Trail knee mirrors this.
P4 — Top of Backswing
The Most Analysed Position in Golf
1
Plane line: Draw a line from the ball through the trail shoulder. At the top, the shaft should be parallel to or slightly below this line (on-plane). Shaft above this line = over-the-top tendency; well below = too flat and inside.
2
Club face direction: At the top, the leading edge of the club face should be roughly parallel to the lead forearm — this is a square face. If the face points to the sky = very closed; if it points to the ground = very open.
3
Lead arm position: A straight or slightly bent lead arm is acceptable. What matters more is the position of the lead arm relative to the shoulder plane — it should stay connected and not lift excessively.
4
Hip turn: From DTL, you should see clear separation between the shoulder turn and hip turn. Tour average: shoulders turn ~90°, hips ~45°. A "reverse pivot" (weight moving to the lead side in the backswing) is immediately visible from DTL.
P6 — Impact
The Moment of Truth
Use slow motion (240fps is ideal) and step frame-by-frame to identify the exact impact frame. Look for:
▸
Shaft lean: At impact, the shaft should lean forward (toward the target) — hands ahead of the club head for irons. Backward shaft lean (casting) is the most common amateur impact fault and the primary cause of poor contact, excessive spin, and loss of distance.
▸
Hip position: The lead hip should be clearly open to the target at impact — not square, not closed. Tour average lead hip open: 35–45°. Restricted hip opening = blocked shots, loss of power, lower back stress.
▸
Head position: The head should be behind or at the ball at impact — not past it. Head moving forward past the ball before impact (coming over the top) is a direct cause of pulls and pull-fades.
▸
Low point: From DTL, check where the club is lowest relative to the ball position. For irons, the divot should start at or just forward of the ball — not behind it. A divot behind the ball = fat strike; no divot = thin or swept.
P7 — Follow Through
The Finish Tells the Story
The follow-through is not adjustable consciously — it is the result of everything that happened before. However, it is an excellent diagnostic window:
▸
Belt buckle facing the target: A full hip rotation through the ball. If the hips are still facing the ball at the finish, rotation was blocked somewhere in the downswing — usually due to restricted lead hip mobility.
▸
Weight on the lead foot: At finish, virtually all weight should be on the lead foot. If the player is balanced across both feet or "falling back," energy was not transferred efficiently through the ball.
▸
Trail foot position: The trail foot should be on its toes at the finish, showing that ground force was generated and the hip cleared. A flat trail foot at finish indicates hanging back through impact.
Face-On Analysis
The face-on view reveals what DTL cannot — lateral motion, spine tilt, head movement, and weight transfer patterns that are invisible from behind. Use both angles together; never rely on one alone.
🔎 The Five Face-On Checkpoints
Address — Face On
Tilt, Width, and Posture
▸
Spine tilt: Draw a line through the spine. A slight away-from-target tilt is correct and normal (particularly with driver — the tee ball is hit on the upswing). An excessively upright or reversed spine at address creates a chain of compensations through the swing.
▸
Shoulder tilt: The lead shoulder should be slightly higher than the trail shoulder at address for irons (trail shoulder drops to hold the club). This is the natural and correct address position — not an error.
▸
Stance width: Feet should be approximately shoulder-width apart for irons; slightly wider for driver. Narrow stance = loss of stability; excessively wide = restricted hip rotation.
The Backswing — Lateral Motion
The Sway vs. Turn Distinction
The most important FO diagnostic is separating rotation from lateral motion in the backswing. They look similar but have completely different causes and effects.
▸
Draw a vertical line through the trail hip at address. In a correct backswing, the trail hip should stay on or slightly inside this line as the shoulders rotate. If the trail hip moves outside this line = lateral sway. Sway forces a compensatory lateral shift on the downswing, producing inconsistent contact and power loss.
▸
Head movement: Draw a vertical line through the centre of the head at address. The head can move slightly (1–2 inches) toward the trail side in the backswing — this is correct and reflects a proper weight shift. Excessive head movement (>4 inches) = sway rather than rotation.
▸
Lead knee action: The lead knee should move slightly toward the trail foot in the backswing (pointing slightly toward the ball is fine). If the lead knee collapses inward dramatically, hip rotation is being restricted by lead hip mobility limitation — not a swing error, a physical limitation.
Impact — Face On
Weight Transfer and Spine Tilt
1
The C-posture vs I-posture check: At impact, the spine should be in a stable "reverse C" (slight away-from-target lean maintained through the ball). A spine that has moved to the lead side (past vertical = "early extension") indicates the hips are thrusting toward the ball — the most common swing fault associated with lower back injury and thin/topped shots.
2
Lead leg straightening: The lead leg should be moving toward straight at impact — not fully straight, but clearly firming up. A "chicken wing" in the follow-through (lead elbow breaking down) is often caused by the lead leg collapsing rather than a pure arm problem.
3
Head position: The head should remain stable and behind the ball at impact. Excessive forward head movement ("chasing" the ball) causes the body to rise and produces thin shots. The eyes should be looking at the ball's original position — not tracking the ball in the air before contact.
The Finish — Face On
Balance and Completion
▸
Full finish posture: At a balanced finish, the player should be upright, in balance, with 90% or more of weight on the lead foot, chest facing the target, and the club over the lead shoulder. A "reverse-C" finish (falling back) indicates energy loss and often reflects a lower back compensation.
▸
Hold the finish for 3 seconds: A reliable test of balance and completion. If you cannot hold the finish position without moving your feet, the swing is out of balance somewhere — most commonly too much lateral motion or insufficient hip rotation through the ball.
Self-Coaching Checkpoint System
Rather than analysing every possible variable, focus on the checkpoints most relevant to your current coaching priorities. This structured system ensures you are tracking what your coach has prescribed — not what you find most interesting to look at.
The Priority Hierarchy
What to Look at First
Always review your coach's most recent session notes before watching video. Identify the 1–2 positions or positions that were the specific focus. Watch only for those first — watching broadly before you know what you are looking for leads to confirmation bias and misdiagnosis.
Self-Coaching Review Sequence
Step 1 — Check coach-prescribed positions only (first pass)
Step 2 — Compare to reference footage from your last coaching session
Step 3 — Note any improvement, drift, or new pattern (second pass)
Step 4 — Identify one question to send your coach with the footage
Step 5 — Update your practice journal entry with findings
The most common self-coaching error: watching broadly, seeing 6 things you want to fix, and changing 6 things. Change only what your coach has prescribed. Everything else is noise until they confirm otherwise.

⚠️
The self-diagnosis ceiling: If you identify something in your video that was not discussed in your last coaching session, do not self-prescribe a fix. Send the footage to your coach with a specific timestamp and question. Fixing an apparent fault without coach guidance frequently introduces worse compensations. Self-coaching is for monitoring — not prescribing.
Apps & Tools
The right software turns raw footage into an analytical environment. All of the following are available on iOS and Android. You do not need all of them — pick one and become proficient with it.
Hudl Technique (Formerly Coaches Eye)
The Industry Standard — Recommended Primary Tool
Used by Tour coaches worldwide. Free tier sufficient for self-coaching; Pro tier adds side-by-side comparison and annotation tools that are genuinely valuable.
✓
Frame-by-frame slow motion with manual scrubbing — the most important feature for impact analysis. Step one frame at a time through the impact zone.
✓
Draw tools: Lines, angles, and circles that can be overlaid on frozen frames. Use the line tool to check shaft plane, spine angle, and the face-at-top position.
✓
Side-by-side comparison: Compare your current swing to a reference swing (your last coaching session, a Tour player, or your best version). This is the most powerful self-coaching feature available.
✓
Share clips: Send annotated clips directly to your coach for remote feedback between sessions.
V1 Golf / OnForm
Premium Coach Communication Platforms
Both are widely used by PGA and CPGA professionals. If your coach specifies one, use that. If not, OnForm has become the more widely adopted platform in the UK for remote coaching workflows as of 2025–26.
✓
V1 Lessons / OnForm Lessons: Send video to your registered coach; they return annotated video with voice commentary. Turns self-filmed footage into a structured coaching interaction.
✓
Swing library: Both store sessions chronologically. Reviewing swing evolution over 6–12 months is one of the most motivating and instructive activities available to an improving player.
Sportsbox AI — 3D Analysis from Your Phone
Significant Addition Since 2024 — Recommended for Phase 3+
Sportsbox AI uses a single smartphone camera to produce 3D swing analysis — measuring pelvis rotation, thorax rotation, arm plane, and kinematic sequence parameters that previously required a dedicated motion capture studio. Now used by thousands of PGA coaches globally.
✓
3D kinematic data from one camera: Pelvis/thorax separation, X-factor, hip-to-shoulder ratio, and early extension measurement — the metrics your TPI coach uses, now available in self-coaching mode.
✓
When to use: Most valuable from Month 5 onwards when approach play becomes the priority focus. Use in the monthly swing audit sessions alongside your HackMotion data.
✓
Works alongside Hudl Technique: Hudl for the visual analysis your coach prescribes; Sportsbox for kinematic data verification. They serve different purposes.

File management habit: After every video session, name and date the clips before storing them. "7iron_dtl_2026-05-10" is infinitely more useful than "IMG_4421". Create a folder per month in your phone's camera roll or cloud storage. Your swing library becomes a powerful progress-tracking tool only if you can find and compare clips across time.

The 20-Minute Weekly Review
The Exact Protocol
1
Minutes 0–3 — Coach notes review: Re-read your notes from your last coaching session. Identify the 1–2 positions you were asked to monitor. Write them at the top of your review log before opening any footage.
2
Minutes 3–10 — DTL review: Open this week's DTL footage in Hudl Technique. Scrub to the prescribed checkpoint(s). Draw the reference lines. Compare to the reference clip from your coaching session. Note: improved / maintained / drifted.
3
Minutes 10–17 — FO review: Same process with the FO footage. Focus on the FO-specific checkpoints most relevant to your current work (sway, early extension, weight transfer).
4
Minutes 17–20 — Log and send: Write a 3-sentence summary in your practice journal: what you observed, what it means for this week's practice, and any question for your coach. If anything notable — improvement or new fault — take a screenshot and send to your coach via Hudl or V1 with a timestamp.
🏆
The compound benefit: Golfers who send weekly video check-ins to their coaches improve 40–60% faster than those who see coaches only in person — because coaching continuity is maintained between sessions. If your coach is not set up to receive and comment on video remotely, ask them to set this up. Every serious low-handicap player uses it.
Integrating Video with Your Coach
The highest-value use of self-filmed video is not solo analysis — it is structured communication with your TPI-certified coach between sessions. This section explains how to make that communication efficient and impactful.
Before Your Coaching Session
Arrive Prepared — Not Just Present
1
Send footage 48 hours before your session. Share your best DTL and FO clips from the past 4 weeks via Hudl or V1. Your coach can identify patterns and prepare a targeted session plan instead of spending 20 minutes diagnosing on the day.
2
Include your observations. A brief note — "I notice my trail elbow is much higher at P4 than the reference clip, and my ball flight has been more fade" — lets your coach validate or correct your self-observation immediately.
3
Prepare one specific question. "Is my hip clearance at impact improving from the last session?" is a better opening to a coaching session than "where do I start?" Specific questions produce specific answers.
During Your Coaching Session
Capture Everything
▸
Film your coach demonstrating the change. A coach showing you the correct P4 position, or demonstrating a drill on their own body, is infinitely more useful on video than in memory. Ask permission and film every demonstration.
▸
Film yourself performing the new change for the first time in the session. This is your reference clip — the version your coach has approved. It becomes the standard against which you compare everything you film in the next 12 weeks.
▸
Record all drill instructions. Either as notes or a voice memo. The exact drill, the pass/fail criteria, and what feedback to look for on video are perishable — don't rely on memory to reconstruct them a week later.

⚠️
The one rule: Never use video to self-prescribe a new change without coach involvement. Video self-coaching is for monitoring and communication — not independent diagnosis. The golfers who get into trouble with self-coaching are those who identify a "fault" in their video, prescribe a fix from YouTube, and spend 6 weeks grooving a compensation that their coach then has to undo. When in doubt, send the footage and ask.
Video Drill Protocols
Structured video sessions that produce diagnostic data, not just footage. Each protocol has a specific comparison method and a clear fault it is designed to expose.
🎬 Diagnostic Protocols
Slow-Motion Swing Video Loop
The Frame-Rate Comparison Protocol
1
Film 10 swings at normal speed (face-on + down-the-line): Use your standard video setup per the Camera Setup tab. Film at 60fps or your phone's standard video mode. These are your baseline clips.
2
Film 10 swings at the slowest available frame rate: On iPhone, use Slo-Mo mode (240fps). On Android, use slow-motion or high-speed video mode. Same angles, same session — no swing changes between the two sets.
3
The comparison: find the last frame before impact in both sets: Scrub to the exact frame where the clubhead is approximately 12 inches from the ball. Compare this frame between your normal-speed and slow-motion clips. This single-frame comparison is the diagnostic moment.
4
What to look for in that frame: Early extension — hips moving toward the ball (visible face-on). Casting — shaft angle shallower in the slow-motion than the normal-speed clip (the eye smooths over this at normal speed). Scooping — handle moving behind the ball (visible face-on in slow-motion; appears as a smooth continuous motion at normal speed).
5
Why this works: Players who appear technically sound at normal speed regularly reveal one of these three faults at 240fps. The eye and brain average motion across frames — slow-motion bypasses that averaging and shows what the body is actually doing in the critical pre-impact window.
💡
Monthly protocol: Run this comparison once per month and archive the last-frame-before-impact image from each session. A sequence of these images across months shows whether your pre-impact position is changing in response to your coaching work — more diagnostic than comparing full-swing video clips.
The Fault-Confirmation Workflow
Connecting Video to Practice
1
Identify the fault in slow-motion first. Do not start practice until you have a specific frame-level observation: "My hips move 3–4 inches toward the ball in the last frame before impact."
2
Connect it to your ball flight. Early extension produces thin contact and pushed/pulled shots. Casting produces fat shots and excessive curve. Scooping produces thin shots and high, weak trajectories. Match the fault to your Mevo data (smash factor, launch angle) to confirm causation.
3
Film the drill, not just the full swing. After identifying the fault, film your corrective drill (chair drill for early extension, half-swing compression test for casting). Slow-motion the drill to confirm the drill is producing the intended constraint.
4
Re-film the full swing after the drill. Compare the last-frame-before-impact image. This closes the loop: fault identified → drill applied → fault reduced → tracked in the session log.
⚠️
The slow-motion trap: Slow-motion makes every minor flaw visible. Most faults visible at 240fps have a negligible impact on ball flight at 60fps — the swing is a dynamic system and some pre-impact positions that look "wrong" in a single frame are corrections for earlier moves in the swing. Always connect what you see in slow-motion to what you measure on the Mevo and what you score on the course. If it doesn't show up in the data, it may not matter.
