Golf Swing Analysis, Frame by Frame
Your swing lasts about a second and a half. V1 GOLF stretches it into hundreds of frames so you can see the exact moment things go wrong — then prove you fixed it.
What swing analysis actually is
Golf swing analysis is the process of recording your motion on video, slowing it to a frame rate the eye can follow, and measuring specific positions against a reference. It replaces guesswork — the feeling that your swing is “too steep” — with a frame you can point at. Nearly every fault a club golfer fights, from a slice to the shanks, shows up as a repeatable deviation at one of eight checkpoints.
V1 GOLF does this on the phone already in your pocket: capture, slow-motion scrubbing, on-video drawing, side-by-side comparison and remote coach review, with no launch monitor and no subscription to get started.
The four-step workflow
Capture the two angles that matter
Face-on exposes weight shift, hip sway and early extension. Down-the-line exposes swing plane and club path. Shoot both at chest height, roughly 8–10 feet away.
Slow it down to 240 frames per second
A golf swing lasts about 1.2 seconds. At normal speed you see nothing. At 240fps you get roughly 290 frames — enough to isolate the exact frame where the fault appears.
Draw the lines that prove it
Shaft plane, spine angle, hip line and a low-point marker turn a vague feeling into measurable evidence you can re-check next range session.
Compare against a reference swing
Load your swing beside a Tour player's — or last month's version of your own — sync at address, top and impact, and watch the difference play out in one screen.
The eight positions you check
Coaches label the swing P1 through P8. Pausing on each frame turns an unwatchable blur into eight still images you can evaluate one at a time.
Address
Setup, ball position, spine tilt
Shaft parallel
Takeaway path and clubface
Lead arm parallel
Wrist set and plane
Top of backswing
Turn, width, face angle
Transition
Sequencing and shallowing
Shaft parallel down
Lag retention, casting
Impact
Low point, hip clearance
Release
Extension, chicken wing
Swing analysis questions, answered
How do I analyze my own golf swing?
Record face-on and down-the-line video at the highest frame rate your phone supports, import both into V1 GOLF, and step frame by frame through P1–P8. Draw a shaft plane line at address and check whether the club returns to it in the downswing — that single check explains most slices, hooks and over-the-top moves.
What frame rate do I need?
60fps is usable, 120fps is good, 240fps is ideal. Most iPhones from the 6s onward and most modern Android flagships shoot 240fps in slow-motion mode.
Do I need a launch monitor too?
No. A launch monitor tells you what the ball did; video analysis tells you why. For fixing swing mechanics, video is the cheaper and more direct diagnostic.
Can my coach review the video remotely?
Yes — send a swing directly to a V1 COACH instructor and get back a voice-over lesson with drawings on your own video. See how that compares to other remote-review apps in our Coach's Eye alternatives guide.
