What Is a Swing Change in Golf Slow Motion?

By Spencer Lanoue
July 24, 2025

Trying to make a swing change often feels like chasing a ghost - you think you’re doing something different, but the ball flight tells another story. Using slow-motion video of your swing is the best way to stop the guesswork and see exactly what’s happening. This guide will show you precisely how to use your phone's camera to diagnose your swing, implement the right changes, and finally make them stick.

Why Your Eyes (and Brain) Can't Keep Up

A golf swing happens in the blink of an eye, lasting roughly one second from takeaway to impact. At that speed, it’s physically impossible for you to process the intricate movements of your hips, shoulders, arms, and club. This is the root of golf's most frustrating dilemma: the gap between feel and real.

You might feel like you’re rotating your hips through impact, but a slow-motion replay might show they’ve stalled completely. You might feel like you kept the club on a great path, but the video reveals a classic over-the-top move. Without an objective look, you’re just guessing. Slow motion removes the bias of feel and gives you cold, hard facts. It shows you:

  • Sequencing Issues: Does your downswing start with your arms or your hips? Slow motion makes the order of operations crystal clear.
  • Positional Flaws: Where is the club at the top of your swing? Is your clubface open or shut at impact? These are details you can only freeze and analyze in slow motion.
  • The True Cause of Bad Shots: You might think you're slicing because of your grip, but the video could reveal your real problem is an open clubface during the takeaway that you spend the whole swing trying to correct.

By slowing things down, you move from frustrating guesswork to a clear, fact-based plan for improvement.

How to Set Up Your Slow-MotionFilming Station

You don’t need any fancy equipment to get started. Your smartphone’s camera is powerful enough to provide the insight you need. The most important elements are stability and consistent angles.

Essential Gear

All you really need is your phone and a simple tripod. A tripod is non-negotiable, holding your phone or propping it against your golf bag will result in shaky, inconsistent videos that are nearly impossible to analyze accurately.

The Two Mandatory Camera Angles

To get a complete picture of your swing, you must film from two specific angles. A flaw that’s obvious from one view can be completely invisible from the other.

1. Down-the-Line (DTL):

  • Setup: Position the tripod directly behind you, so the camera lens is level with your hands at address. Aim the camera so it’s pointing down your foot line, straight toward the target.
  • What it Shows: This angle is perfect for analyzing your swing plane (the path the club travels on) and clubhead path. It’s how you diagnose casting, coming “over the top,” or getting the club “stuck” behind you.

2. Face-On (FO):

  • Setup: Position the tripod directly in front of you, perpendicular to your target line. The lens should be roughly belly-button height and centered with your body.
  • What it Shows: This angle is best for seeing body movements. It clearly shows your weight shift, hip rotation (or lack thereof), posture changes (like standing up at impact), and ball position.

For both setups, place an alignment stick on the ground pointing at your target. This gives you a clear visual reference line when you review your footage, making it much easier to spot swing path deviations.

A Step-by-Step Guide to Reviewing Your Swing

Now that you have your 'before' footage, it’s time to play detective. The goal isn’t to look exactly like a Tour pro - it’s to spot the major deviations from sound fundamentals that are costing you consistency and power.

Step 1: Get a Baseline

Film at least five full-speed swings from both the DTL and FO angles. A 7-iron is a perfect club to start with. Don’t try to make your prettiest swing, just swing like you normally would on the course. This is your honest baseline.

Step 2: Know What You're Looking For (The Key Checkpoints)

When you sit down to review, don't just watch the whole swing over and over. Use the scrubber on your video player to pause the swing at critical checkpoints. Here’s what to look for at each stage:

Checkpoint 1: The Takeaway (Address to Hip-High)

From the DTL view, the first few feet of the backswing should be a “one-piece” movement of the chest, arms, and club. A common mistake is sucking the clubhead too far inside the hands early. Ideally, when the club is parallel to the ground, it should also be parallel to your target line (or very slightly inside it).

Checkpoint 2: Halfway Back (Club Shaft Parallel to the Ground)

From the Face-On view, check your body movement. Are you swaying away from the target or rotating around your-spine? You want to see rotation, not a big lateral shift. From the DTL view, notice where the clubhead is in relation to your hands, a good position is to have the club head hiding your hands, or slightly outside of them.

Checkpoint 3: Top of the Backswing

Pause at the very top. From the DTL view, a good checkpoint for most golfers is to have the shaft pointing parallel to the target line. If it’s pointing way to the right of the target (laid off) or way left (across the line), it often requires a major compensation on the way down. From the FO view, you want to see that you've maintained your body's tilt from address and your weight has loaded into your trail leg.

Checkpoint 4: Transition and Downswing

This is where most swing flaws reveal themselves. As you start the downswing from the top:

  • DTL View: Does the club "steepen" and move out toward the ball (the definition of an "over-the-top" move)? Or does it "shallow" and drop down on a path slightly more inside than your backswing path? Most good ball-strikers shallow the club.
  • FO View: What moves first? The correct sequence starts with the lower body. Your left hip (for a righty) should shift slightly toward the target and begin to rotate, pulling the rest of your body through. If your arms and shoulders start first, you’re losing immense power and control.

Checkpoint 5: Impact

Freeze the frame at the moment of contact.

  • FO View: Good impact looks much different than your address position. Your hips should be open towards the target, a majority of your weight should be on your front foot, and your hands should be slightly ahead of the clubhead.
  • DTL View: Check your posture. Have you stood up out of the shot, lifting your chest and head? Maintaining your posture angles from address through impact is something you see from all great players.

How to Actually Fix Your Flaw with Drills

Diagnosing a problem is only half the battle. Now you have to fix it, which requires overwriting years of muscle memory. This is where the true power of "feel vs. real" comes into play.

Step 1: Isolate One Change

Pick the single most significant fault from your diagnosis and commit to fixing only that. If you come over the top, make that your mission. Trying to fix three things at once will short-circuit your brain.

Step 2: Find Your Exaggerated Feel

Your old, flawed swing feels "normal." A technically correct swing will feel completely alien. Therefore, to get from flawed to correct, the CURE must feel like a wild exaggeration.

  • To fix an over-the-top swing, you must feel like you are dropping the club so far behind you that it seems like you’ll hit your back shoe.
  • To fix a sway off the ball, you must feel like you are staying completely still while your shoulders simply turn in a barrel.

Step 3: The Rehearsal Cycle

This cycle is how you turn a new feeling into a new habit:

  1. Drill without a Ball: Make slow, deliberate practice swings focusing *only* on your new, exaggerated feeling.
  2. Film the Drill: Record yourself doing these slow-motion rehearsals.
  3. Check the Video: Now, look at the recording. This is the moment of truth. Does your crazy, exaggerated *FEEL* produce the correct *look* on camera? You will be shocked to find that what feels like an extreme change often looks just right on video. This is how you recalibrate your feelings.
  4. Introduce a ball...very slowly. Begin hitting balls with a tiny, half-swing, still focused only on the exaggerated feel. Forget where the ball goes. Your only job is to perform the feeling correctly.
  5. Gradually build speed. As you get more comfortable, slowly increase the length and speed of your swing. If the old flaw creeps back in at 70% speed, go back to 50% and groove it more.

This deliberate process of feeling, filming, and confirming is the fastest and most effective way to change your golf swing for good.
