Slow-mo, frame-by-frame, draw lines and angles, side-by-side compare
Film Room quick start
Record films right here with the phone's camera, or Load video picks a clip you already have. Either way it stays on this phone; nothing uploads.
Slow it down (to 1/10th speed) or step frame by frame with ⟨ ⟩.
Pinch to zoom, drag to look around, double-tap to jump in and out. No tool is selected by default; pick Line, Draw, or Angle (tap three points: thigh… knee… shin) to mark up the frame; tap the tool again to put it away.
Skeleton runs on-device motion tracking: a live skeleton with automatic knee and hip angles, straight out of the video. Track several follows several athletes at once: tap one to follow just them, tap the ✕ on the chip to go back to everybody. Skeletons landing on the crowd instead of the runners? Tap Track zone and drag a box over the lanes. Anyone outside the box is ignored, and the model searches inside it a piece at a time, which is how runners far down the track get found at all. Pinching to zoom in on them does the same job for a single athlete.
Compare loads a second clip side by side (same athlete last month, a teammate, or any reference clip you have) with synced play and per-clip frame nudge to line them up.
Ghost lays clip B over clip A, see-through. Line up the starts with the nudge buttons and watch the two runs move through each other.
Save clip files it in the on-phone library under an athlete's name; Voice-over captures your voice plus everything on screen (play, scrub, draw while you talk) into a video you can share straight to the group chat.
New here? Tap Record, film a sprinter from the side for 5 to 10 seconds, then tap the skeleton. That's it.

Two things a known distance apart, in the plane the movement happens in: cones or lane marks along a run, a metre stick or taped marks on the rack for a lift. Then tap one, then the other.
