Drag any joint marker to correct its position. Corrections apply
only to this frame and improve this lap's own metrics — they do
not change how future videos are automatically analysed.

Draw Feedback on Video
Play or scrub the video, pause wherever you want to make a point,
then tap "Start Drawing" and mark it up. Each marking is saved to
the exact moment you drew it — nothing is baked into the video
itself, so it's never destructive.
