How to film a training video for form analysis
Most training clips are unusable for reviewing form, and almost always for the same handful of reasons: the camera is too close, the athlete leaves the frame, or the angle hides the joint that matters. None of that requires better equipment to fix. It requires a few decisions before you hit record.
Put the whole body in frame, the whole time
The single most common problem is cropping. A clip that cuts off feet cannot show stance, weight shift, or landing. A clip that cuts off the head loses trunk position.
Frame so there is visible space above the head and below the feet for the entire rep, including the parts where the athlete is highest and lowest. If you are filming a jump, frame for the top of the jump. If you are filming a squat or a start, frame for the bottom position.
Film from the side for most movements
Side-on is the default for a reason. It shows hip and knee angles, trunk lean, and the sequence of a movement over time — the things that are invisible from the front.
- Side view: squats, sprint starts, jumps, throwing, swings, pitching, lifting
- Front view: landing alignment, stance width, symmetry between left and right
- Both, on separate reps: anything you want to look at carefully
Do not try to split the difference with a 45-degree angle. It compresses everything and makes joint positions harder to read, not easier.
Keep the camera still
A moving camera makes it impossible to tell whether the athlete moved or the frame did. Prop the phone against a bag, a bottle, a fence post — anything stable. A tripod is nice and completely optional.
If someone is holding the phone, tell them to plant their feet and not track the athlete. A still frame with the athlete moving through it is far more useful than a smooth pan.
Get the distance right
Roughly 10 to 15 feet works for most single-athlete movements. Close enough that the body fills a good portion of the frame, far enough that nothing leaves it.
Resist the urge to zoom. Digital zoom throws away resolution, and you will usually need the extra margin when the athlete moves further than expected.
Light the athlete, not the camera
Shoot with the light behind the camera, not behind the athlete. Filming toward a window, a gym light, or a low sun turns the athlete into a silhouette, and a silhouette hides exactly the joint angles you are trying to see.
Outdoors, overcast is easier than bright sun — harsh shadows across the body are their own problem.
Wear something that shows the body
Loose, baggy clothing hides the hips and knees. Fitted clothing is not required, but a clip where the outline of the legs and torso is visible is a great deal easier to review than one where it is not.
Contrast helps too. Dark clothing against a dark background is hard to read for a person and for software.
One clean rep beats ten rushed ones
A short clip of one representative rep is more useful than a long clip of many. Two to sixty seconds is plenty. Film the rep you would actually want feedback on, not the warm-up.
If you want to compare progress later, film the same movement from the same angle and distance next time. Consistency between clips is what makes two sessions comparable at all.
A quick checklist
- Whole body in frame, top and bottom of the movement included
- Side view unless you are specifically checking alignment
- Camera still and propped
- 10 to 15 feet back, no zoom
- Light behind the camera
- Clothing that shows the body outline
- One clean, representative rep
Get those right and the clip is worth reviewing — whether you are watching it yourself, sending it to a coach, or running it through a report.
