Golf swing analysis, frame by frame

Practical guide · Updated August 8, 2026

Compare a golfer's swing with a coach demonstration, a personal best, or a reference clip. WithCoach keeps both videos aligned around the same swing phase so changes in posture, sequencing, and club path are easier to see.

The app combines side-by-side playback, a shared sync point, individual frame steps, drawing annotations, and speeds down to 1/8x. Local comparisons are unlimited on the Free plan; exports and sharing include a WithCoach watermark.

How to record useful golf video

Record one angle at a time and keep the camera position repeatable. Consistent footage makes progress visible instead of introducing a new perspective on every session.

Down-the-line: place the camera near hand height, aimed through the hands toward the target line.
Face-on: keep the camera perpendicular to the target line and far enough away to include the full club.
Leave a clear view of the feet, hips, hands, clubhead, and ball throughout the swing.

Four moments worth comparing

Address

Compare stance width, spine angle, hand position, and distance from the ball before motion begins.

Top of backswing

Check head movement, hip turn, lead-arm position, and the club's relationship to the target line.

Impact

Set the sync point at ball contact, then compare weight shift, shaft lean, hip opening, and head position.

Finish

Review balance, rotation, and whether the finish is repeatable across attempts.

A repeatable analysis workflow

Import the player's swing and a reference swing into one comparison.
Move each clip to impact and lock those moments as the shared sync point.
Scrub backward through transition and forward through the finish while both clips stay aligned.
Pause on one actionable difference and mark it with a line, angle, arrow, or circle.
Save or share the review, then record the next attempt from the same camera angle.

A useful review does not need dozens of marks. One clearly synchronized difference, one visual cue, and one new attempt give the athlete something concrete to act on. The next comparison then shows whether that change held.

Frequently asked questions

What camera angle is best for golf swing analysis?

Use separate down-the-line and face-on recordings. Keep the camera position and height consistent between sessions so the comparison reflects the swing rather than a changed perspective.

Can WithCoach compare 30 fps and 60 fps golf videos?

Yes. WithCoach uses the real timing of each clip when the videos are synced, so mixed-frame-rate footage can be reviewed on a shared timeline.

Can I use a professional swing as the reference?

Yes. You can compare against a coach demonstration, your own best swing, or an eligible reference video imported into the app.
