How to record the play AFTER it happened (retroactive replay)

Anyone who plays volleyball, footvolley or beach tennis knows the scene: the best point of the day happens exactly when nobody was filming. You remember the play, the group talks about it during the break, but the video simply doesn't exist.

The traditional fix is leaving your phone recording the entire game. It works, but it produces a huge file nobody will ever watch, heats up the device, and forces you to dig through two hours of footage for the ten seconds that matter.

There is a better way: retroactive replay. Instead of recording everything, the app continuously keeps only the last few seconds — and you decide to save after the play happens.

The trick is called a continuous buffer (or circular buffer). Picture a video conveyor belt that never stops: the camera records all the time, but only keeps the last few seconds in memory. Anything older is discarded automatically.

When you tap the replay button, the app grabs exactly what is on that belt — the last 5, 10, 22, 30 or 50 seconds, depending on your settings — and saves it as a permanent clip.

In other words: you don't need to predict the play or press record beforehand. The camera already saw everything; your tap just says "this one is worth keeping". It's the same principle as a TV broadcast replay, running on your phone.

A common question: if the app records all the time, doesn't it fill up my storage? No — and the reason is where the buffer lives. KplaWY keeps the buffer in the device's RAM, not in storage.

RAM is the phone's working memory: fast and volatile. Video cycles through it and is continuously overwritten, without writing anything to disk. Only when you save a replay does that segment become a real file in your gallery.

In practice, two hours of play can end with half a dozen clips of a few seconds each — a few megabytes — instead of a single multi-gigabyte video.

First, position your phone with the whole court in frame — a tripod or a fence mount does the job. Then pick the buffer duration in settings: up to 10 seconds on the free plan; 22, 30 or 50 seconds as well on KplaWY Pro.

Tap to start capturing and go back to the game. The app keeps recording continuously, discarding what doesn't matter. Did the play just happen? Tap REPLAY — on the phone screen, on your smartwatch, or on a Bluetooth button — and the last seconds are saved instantly.

During the break, review the clips in the app gallery and share them with the group. Everything stays on your device: nothing goes to the cloud unless you send it.

No. The buffer runs in RAM and is continuously discarded; only the replays you save take up space. Capture works 100% offline — internet is only needed for login, subscription, and optional backup.

It depends on the configured duration: the buffer holds between 5 and 50 seconds. Up to 10 seconds on the free plan — enough for most volleyball and footvolley points. KplaWY Pro unlocks 22, 30 and 50 seconds, useful for long rallies or plays built from the serve.

The tap saves whatever is in the buffer at that instant. If the buffer is 22 seconds and you tap 5 seconds after the point, the clip covers the 22 seconds before the tap — the play is in there. The tip is to set a buffer with headroom over your reaction time.
