Film from the side of the rink with your phone held upright, and keep the whole body, head to skates, in the frame the entire time. Side on, upright, full body: that is what lets HLH read the angles at all. Film from the front, or cut off the head or skates, and we cannot grade the clip. The standing start and the strides below make a good clip great, but this is the one that makes or breaks it.
Just tap Film Now. HLH records at high frame rate automatically, so you can skate at full game speed and every frame is still captured. One clip covers every metric, and there are no camera settings to change.
Phone upright. Keeps the whole body in frame while you follow.
Phone sideways. Harder to keep head and skates in frame while panning.
Skate at real game speed. The camera catches every frame, so film how you actually play.
Coasting or half-effort hides your true mechanics.
The camera shows a framing box. Move closer or further until your player's whole body, helmet to skates, fits inside it and the box turns green. When it is green you are at the right distance, so there is no exact number to worry about. Filming too far away is the #1 reason analyses fail, so fill the box.
Start from a standstill, tall and upright for a second, not crouched in a ready position
Then explode into your first 3 hard strides plus 4 to 6 more, 6 to 10 in total, at full game speed
