Upload a full range-session video (slow motion welcome). Every swing is detected, verified with pose estimation, and cut into a single-swing clip. Then you pick the ones you actually hit and send them to analysis — a ball strike and a practice swing look and sound identical on video, so you're the judge, not a guess.
Large sessions upload and process in a few minutes — once the upload finishes you'll jump to a page that refreshes itself until the clips are ready.
