How is indoor high jump different from outdoor?
Three things change when a high jumper moves inside for the winter, and the technique is usually not one of them.
A high jumper who cleared a height clean outdoors in September and then scrapes the same height indoors in January usually has not lost any technique at all. Something about the room changed, not the jump.
What's actually different indoors
- No wind: an outdoor approach run into even a light headwind or crosswind changes a jumper's stride in ways they correct for without noticing, and removing that can make the same approach feel, and look, longer or faster than it actually is.
- A shorter or more boxed-in run-up: indoor arenas built around a banked sprint track often leave less room for a full approach curve than an outdoor infield does, and a jumper used to a long run has to genuinely shorten it, not just repeat the old one in less space.
- Different light and sightlines: flat overhead arena lighting removes shadows a jumper partly uses to judge the bar and their own distance from the standards, and a crowd close to the runway changes what the background behind the bar looks like.
None of that is a technique problem, which is exactly why coaching the plant leg after an indoor miss, when nothing was wrong with it outdoors three months earlier, usually fixes nothing.
Where the Film Room fits
The high jump setting reads hip rise as a share of body height, takeoff angle and knee fold the same way regardless of venue, because those are proportions and angles taken off the athlete's own body, not measurements of the room around them. Film indoors and outdoors from the same side-on distance and the two sets of numbers are directly comparable.
A single camera cannot measure the wind, the run-up length or the lighting an athlete is actually jumping under. What it can do is show whether the body's own numbers changed between the two venues, which is the real way to tell whether an indoor miss is about the room or something that quietly drifted in the technique.

Why does my high jumper lean away from the bar before they even reach the plant?
Some inward lean on the curve approach is correct high jump technique, the fault is starting it too many steps out, and film shows exactly when it begins.

A side-on camera reads the vertical arc of a jump well and has no idea where the plant foot actually landed on the ground, which is usually the real question.

The high jump setting reports hip rise and takeoff angle, not centimetres off the bar, and the reason is worth knowing before you expect the other thing.
