How to Analyze Your Kid's Swing on Video (Free)

Your phone is the best coaching tool you own, and you already have it in your pocket. The catch is that most swing videos are filmed and reviewed in a way that hides the very things you're trying to see. Here's how to film it right, what to actually look for, and the mistakes to avoid.

Quick answer: Film from directly to the side, hip-height, in slow motion, from the same spot every time. Then scrub frame by frame and check a few plain-language things: balance at the finish, whether the front side flies open, the barrel's path to the ball, and a still head. Pick one thing to fix, not five.

How to film it so the video is actually useful

A bad angle turns good analysis into guesswork. Before you worry about what to look for, get the footage right. Three rules cover almost everything:

Film a few swings, not one. The first swing is often a warm-up. Get three or four clean ones off a tee or soft toss so you're analyzing a pattern, not a fluke.

What to look for (in plain language)

You don't need coaching jargon. You need a short checklist of things you can genuinely see. Scrub the video slowly and check these four:

CheckpointWhat good looks likeRed flag
Balance at finishEnds under control, weight stacked, could hold the poseStumbles, falls off toward the plate or away from it
Front sideFront shoulder and hip stay closed until the swing startsFront shoulder "flies open" early, pulling everything off the ball
Barrel pathBarrel works down and into the ball on a tight, direct pathHands push out and the barrel loops around the ball (long swing)
HeadHead stays quiet and still, eyes down to contactHead drifts, pulls up, or lunges forward before contact

Watch each checkpoint on its own pass through the video. First watch just the head. Rewind, watch just the front shoulder. Trying to watch everything at once is how you end up seeing nothing. And compare against a reference: pull up a slow-mo clip of a solid hitter filmed from the same side angle, and the differences jump out.

The common mistakes parents make

Filming is the easy part. The review is where good intentions go sideways. The usual traps:

Where the guessing ends

Here's the honest gap in all of this. Filming the swing is free and easy. Seeing that something's off is doable with the checklist above. But knowing the one thing to fix, and the drill that fixes it, is the part that actually takes a coach's eye, and it's the part parents get stuck on.

That's exactly what Fungo's swing analysis is for. You upload a swing video, and the app reads it from sampled frames across the swing and tells you the single most valuable thing to work on, in plain language, plus a drill from a real coach to fix it. Then you film a follow-up a few weeks later and it compares the new swing against your baseline, so "he looks better" becomes something you can actually see side by side.

You do the free part with your phone. Fungo does the part that's hard to do alone.
