How to Record the Last 30 Seconds of Video

You cannot record the past with a normal camera app — by the time you press record, the moment is gone. Videotapr solves this by keeping a rolling buffer of the last 30 seconds while the camera is open. When something happens, you tap once and the app saves the previous 10, 20 or 30 seconds as a video clip. Nothing before that is kept, so you do not end up with hours of footage to scroll through. That is how padel and tennis players use it courtside, parents use it on the touchline at their child's game, and dog owners use it in the garden.
Key facts
- Clip lengths: 10, 20 or 30 seconds, chosen before or during recording
- The buffer runs continuously while the camera screen is open
- One tap saves what already happened — no need to predict the moment
- Clips are saved to your phone; nothing is uploaded to a server
- Available on Android and iOS, plus Wear OS (with Android) and Apple Watch (with iPhone)
- A clip can run 1 to 2 seconds longer than the length you picked
Free on Android and iOS — 3 clips a day, no account needed.
How does recording the past actually work?
The app opens the camera and starts writing video into a short buffer: a temporary file inside the app that is constantly overwritten. Think of it as a 30-second loop that is always running and always throwing away the oldest frame.
When you tap the save button, the app takes the contents of that loop and writes it out as a normal video file. The moment you tapped becomes the end of the clip, not the beginning. That is the whole trick, and it is why you can capture something you did not see coming.
Which clip length should you choose?
| Length | Best for | Example |
|---|---|---|
| 10 seconds | Just the finish | The smash, the goal, the winning shot |
| 20 seconds | The point from start to end | A rally, a build-up, an attack |
| 30 seconds | The point plus what follows | A long rally and the celebration after |
What do I need to do before the moment happens?
Only one thing: have the camera screen open and pointed roughly the right way. You do not need to press anything, and you do not need to guess when something good is about to happen.
Most people prop the phone against a bag or a fence at the side of the court or field, open Videotapr, and leave it. The buffer does the rest.
How do you record the last 30 seconds, step by step?
- Open Videotapr and point the camera at the action.
- Choose your clip length: 10, 20 or 30 seconds.
- Leave the app open. The buffer runs on its own.
- When something happens, tap the save button — or swipe up on your watch.
- The clip lands in your sessions list, ready to watch or share.
Does this fill up my phone?
No, and that is the point. A traditional approach is to record the whole session and cut it later, which means a one-hour match becomes a multi-gigabyte file you then have to scrub through.
With a rolling buffer, only the clips you actually tapped end up in your gallery. The buffer itself is a short temporary file that is constantly overwritten, so the space Videotapr uses does not grow with the length of the session. Ten saved clips of 30 seconds take up about 150 MB at the default setting, instead of an hour of video.
What if I react too late?
Then the moment is gone. The buffer holds at most 30 seconds, and older frames have already been overwritten. In practice people react within a few seconds, so this rarely happens — but it is a real limit and worth knowing about.
