How to Film Your Golf Swing — Angle, Frame Rate, and Framing
In swing video analysis, most of the result quality is decided before any software runs. This is true of every tool: if the ball is missing entirely between two frames, no algorithm can recover that gap.
The good news is that what you need is not equipment but five habits. Learn them once and they apply themselves every time.
1. Angle — what you want to see decides the angle
There is no single "good angle." Each one shows different things, and what one angle shows, the other hides.
| Angle | What you can see | What you cannot |
|---|---|---|
| Down the line (behind the ball, along the target line) | Start direction, curve, club path, swing plane | Weight shift, vertical movement |
| Face on (facing the body) | Weight shift, sway, hand height, tempo, head movement | Ball direction, club path |
If you want ball flight, it has to be down the line. The camera needs to look along the direction the ball travels for the trajectory to have depth. From the front or the side, the ball leaves the frame almost immediately and tracking breaks.
Stand the camera 2–3 m behind the player, at waist to chest height. Too low and the club path will look more in-to-out than it is; too high and it will look out-to-in. If you are filming to diagnose a swing, that height changes your answer.
2. Framing — the first 1–2 m after impact matter most
A trajectory starts at impact. The moment the ball leaves the face and the first metre or two of flight carry most of the information needed to compute the curve. If that section is outside the frame, nothing else in the clip can tell you which way the ball started.
- Place the ball in the lower third of the frame. The upper two thirds become the room the ball climbs into.
- Do not zoom in. The ball will leave the frame right after impact.
- Too far away and the ball becomes a few pixels, which is hard to detect. Full body in frame but not filling it is the balance point.
- Vertical framing works better, because the ball goes up rather than sideways. It also shares better.
3. Frame rate — at 30fps the ball disappears between frames
This is the item that changes results the most, and the one most people never touch.
A driver shot leaves the face at 55–65 metres per second even for amateurs. At that speed, here is how far the ball moves between frames.
| Frame rate | Gap between frames | Ball travels | Result |
|---|---|---|---|
| 30 fps | 33 ms | about 2.0 m | The impact window can fall entirely between frames. Broken traces and wrong start points. |
| 60 fps | 17 ms | about 1.0 m | Recommended minimum. Ball flight traces reliably. |
| 120 fps | 8 ms | about 0.5 m | Club head path becomes clean too. |
| 240 fps | 4 ms | about 0.25 m | For studying impact itself. Large files, and quality drops in low light. |
The point is that at 30fps the ball jumps two metres per frame. For ball flight alone 30fps is workable, but it is not enough for club head path. The club head is moving over 40 metres per second near impact, so at 30fps the impact itself may not exist in any frame.
Where to set it — on iPhone, Settings → Camera → Record Video, choose 1080p at 60fps or better. On Android, the frame rate sits next to resolution in the camera app's video settings. Slow-motion modes usually record at 120fps or higher and are better still, though they lose quality in dim light, so indoors 60fps can be the better choice.
4. Light — into the sun, a white ball vanishes into a white sky
Ball detection uses colour and shape cues together. Shooting into the sun turns the ball into a silhouette, stripping the colour cue, and flattens contrast against a bright sky, weakening the shape cue as well.
- Put the sun behind you so it lights the ball from the camera side.
- Overcast days are actually better. No shadows, no harsh contrast, even conditions throughout.
- Early morning and late evening put the sun low, which makes backlight easy to walk into. Check your direction twice.
- In a dim indoor bay, do not push the frame rate. Shorter exposures make the ball dark and smeared.
5. Background — sky is the best background there is
A ball crossing open sky is the easiest thing to detect. Trees, spectators, signage, someone else in a white shirt — busy backgrounds mix colour and shape cues and produce false detections.
Lowering the camera slightly so the ball climbs above the horizon improves results for this reason. Indoors, facing a plain wall achieves the same thing.
When the trace comes out wrong — diagnosis by symptom
| Symptom | Cause | Fix |
|---|---|---|
| The trace breaks partway | Ball left the frame, or frame rate too low | Zoom out and shoot at 60fps or higher |
| It follows the wrong thing | Something white or moving in the background | Turn toward sky or a plain background |
| The trace starts in the wrong place | Impact happened outside the frame | Reshoot with the ball in the lower third |
| Everything is dark and soft | Backlight or low light | Turn the sun behind you; indoors, drop the frame rate for brightness |
| Club tracks but ball does not | Ball is too small in frame | Move 1–2 m closer and reshoot |
The sixth one — film from the same spot every time
It did not make the list of five, but in practice it makes the biggest difference.
The value of video analysis comes from comparison, not from any single swing. To compare last week against today, the camera position, height, and distance have to match. Move the camera and the club path looks different — and you cannot tell whether the swing changed or the camera did.
At a range, always using the same bay and the same spot for the phone is enough.
With Shashot
Shashot stabilizes hand-held footage before analysis, so a tripod is not required. With the conditions above the trace usually lands correctly the first time, and when conditions are poor the trace can still be adjusted by hand. Following these five simply removes most of that adjustment work.
Common questions
Can I film in slow motion?
Yes, and it usually helps — slow motion typically records at 120fps or more. It does lose quality in dim light, so indoors 60fps can be the better option.
Vertical or horizontal?
Vertical. The ball travels upward, so a vertical frame holds the trajectory longer. It also shares better.
How far back should I stand?
2–3 m behind the player, with the full body in frame but not filling it. Further and the ball becomes a dot; closer and it leaves the frame right after impact.
Does this work at an indoor range?
The trace works for as long as the ball is in frame. Full ball flight will not develop over a short distance, but club head path and swing tempo are fully readable indoors. Indoors, work on those.
Can I use video I already filmed?
Yes, import it from your camera roll. Clips that do not meet the conditions above may produce a lower quality trace.
