AI-powered computer vision game analysis
What happened in this rally?
Players, ball, actions and positions arrive on the video one layer at a time, the way the match screen shows them.
Beachmates Vision · Computer vision · private beta
From the match video to beach volley stats, automatically.
Upload a match filmed with a single camera. Our AI and computer vision models find the four players, the ball, every contact and every rally, then lay the match out player by player, on a 2D court. You tag nothing by hand: you review, you correct, and Vision runs again with your corrections.

Before Vision
Still rewinding the video to find one rally?
The match is filmed. Then comes the long part: watching it again, pausing on every rally, writing each serve down, scrubbing back to the block you wanted to show. Hours of video, read by hand. Vision reads it for you.
By hand
Scrub through the whole video to find one rally.

Every moment and every rally opens the video at the right second.

Write every serve down on paper, rally after rally.

Serves, receptions, attacks and blocks counted for each player, ready to export.
One rally, layer by layer
What does Vision see in a single serve?
Each step adds a layer to the video, from the players to the score.
1 Players
Who is on court?
Vision detects the four players and follows each one through the rally, with a colour and a number that stay the same on the video, the court map and every stat.
2 Skeleton view
How does each body move?
The models follow each player's body frame by frame and draw it as a skeleton over the video, so you see the posture behind every contact.
3 Ball
Where does the ball go?
The algorithm detects the ball and follows it in the video.
4 Actions
Which touch was it, and by whom?
Vision recognises each contact, names it (serve, reception, set, attack, block, defence) and gives it to a player.
5 Live positions
Where was everyone standing?
Each detected player is placed on a 2D court, so the live positions map shows the four players at every moment of the rally.
6 Rallies and score
Which rallies made the set?
Vision cuts the match into rallies and finds who won each one. Every rally sits on the match strip, coloured by the winning team, and the score follows.
Try the match screen
Which action do you want to see again?
Pick an action in the list or on the strip: the view jumps to that moment and shows who touched the ball. On the match screen, every contact of the match works this way and opens the video at its second.

One match, read for you
The questions a coach asks after a game. Each one gets its own view.
Every section of the match screen opens on a question like these, and answers it on a court.
- 01 Moments: what should I watch first?
- 02 Serves: where do they go?
- 03 Reception: who wins the point, and how far does the setter run?
- 04 Attacks: where does the ball go, and who wins the point?
- 05 Blocks: what do we stop, and where?
- 06 Positions: where do we move on the court?
- 07 Commentary: what happened, rally by rally?
- 08 Score: how did the points come?
- 09 Workload: how much ground do we cover?
- 10 Who should we serve?
01 /Serves and receptionExample data · fictional pair
Where do they serve, and who wins the point?
One arrow per serve, from the server to where the ball was taken. Switch to reception: each line runs from the ball taken to where the next ball was played, coloured by the point won or lost, with the setter's run dotted behind it.

02 /Attacks and blocksExample data · fictional pair
Where does the ball go, and what do we stop?
Two dots per attack: where it was hit, and where the opponent answered. One marker per block, at the blocker's contact along the net, joined to the attack it stopped.

Questions
Before you send a match
How does Vision work?
You send the video of a match filmed with one camera. Our computer vision models analyse it automatically, on our servers: they detect the players, the ball, the contacts and actions, the positions and the rallies. The analysis takes 15 to 30 minutes. If something looks wrong, you correct it and Vision runs again with your corrections.
What kind of video does it take?
One file per match, H.264 or HEVC, up to 2 GB, filmed from one fixed viewpoint behind the court with the whole court in frame.
Where do I put the camera?
Behind the baseline, slightly raised, centred on the court. One camera, one court, and you do not touch it again until the last point.
Do the players need to wear anything?
No. No sensor, no marker, no special bib. Everything is read from the video.
How long does the analysis take?
15 to 30 minutes once you launch it. The match list shows each step while it runs.
Can I analyse a training session?
Yes. When you set up a video, you file it as a competition or as a training session.
What if it gets a player or an action wrong?
You change it from the match screen, then run the match again with your corrections in it.
Can I take the data elsewhere?
Yes: rallies, serves and attacks export as CSV, and the scouting sheet prints on one A4 page.
In which languages?
English, French, German, Italian, Polish, Portuguese, Russian and Greek.
Who sees my matches?
The account that uploaded the video, and the players of the Beachmates match it is linked to.
Is there anything to pay?
No. Beachmates Vision is free during the beta.
What will your next match tell you?
