The problem: hours of video, seconds of gold
Anyone who has filmed a whole match knows the ritual: battery draining, storage-full warnings, and then an hour hunting three good plays inside a giant file.
The buffer flips the logic. Instead of deciding beforehand what is worth it, you decide afterwards: the play happened, it was good, it became a clip. The rest never takes up space.
The step-by-step on court
Arrive a few minutes early and frame the area where the action happens, with the phone steady on a tripod or stand. Open KplaWY, check the framing on screen, and get in the game.
Keep control within reach: watch on your wrist, Bluetooth button in your pocket, or another phone with a partner. When the point ends, tap REPLAY without rushing — the previous seconds are already stored.
Short or long buffer?
For quick point plays, a short window does the job and keeps everything light. For built-up plays, like a long rally or a training sequence, set a longer window before you start.
The rule is simple: the window must cover from the start of the play to your tap. Test once during warm-up and adjust.
From clip to share
Every saved replay is a short standalone video: watch it on the spot, go back a few seconds, control the speed, and send it to the group with zero editing.
At the end of the session, delete the duds on the spot and keep only the best. Your camera roll will thank you.
Frequently asked questions
What if I tap REPLAY too late?
Set the buffer window longer than your reaction time. If a play slips away, increase the duration before the next match.
Is the saved video full camera quality?
Yes. The clip comes from the same phone camera feed, with no screen-record recompression or mirroring loss.
Can I use it without a tripod?
Yes, resting the phone on something steady. But a tripod is worth it: stable framing makes far better replays.
