Tap Me Volleyball turns a phone video of an amateur volleyball match into vertical highlights of you. Amateur players film every match, but nobody edits ten minutes of footage to find their own plays — you are one small figure among twelve. In Tap Me, a player picks the match video, pauses on any frame and taps themselves once (optionally with a hint like "green jersey #6"), then closes the screen. The app finds every rally, finds the player in each one, and makes a 9:16 highlight per rally that follows them from the serve to the point, with every other face blurred, a note on which team won the point, a combined reel and optional broadcast-style subtitles in Korean, Japanese and English. A push notification arrives when they are ready, and everything saves to Photos in one tap.

It is built for Baegugu, a Korean amateur volleyball community, and runs as a members-only mobile web app. On a 10-minute 1080p match (18 rallies) on our 32-core server, rally finding took 4 minutes, the first highlight was ready in 9 minutes and 12 highlights plus the reel in 22 minutes, for about $2 of Meta API usage; across five earlier end-to-end runs the right player was picked in 29 of 30 rallies (in one more, the track later drifted to a teammate). A highlight is made on its own only when the model is at least 0.9 sure and the player is on the near side of the court; otherwise the app asks "is this you?" or skips far-side rallies, which the player can still pick by hand. Longer matches are handed over 10 minutes at a time without uploading again. Uploads and highlights are deleted 24 hours after upload, and showing anyone else's face unblurred requires the user to confirm those people agreed.

Judges can try the app at https://highlight.baegugu.com/tapme?invite=j6IO7gOz (it skips the Baegugu member login). It works with any phone-recorded volleyball match up to 10 minutes; footage of other club members is not shared, so the demo video shows a real run.
