What this is
A delayed replay, the thing gymnastics clubs bolt to the wall — without the hardware. Your phone films the trick and this screen plays it back a few seconds later, so you land, look up, and watch the rep you just did. No walking over to the camera, no scrubbing, no thirty seconds of admin between attempts.
That gap is the whole point. Watching an attempt seconds after landing it means you can still feel what you did while you look at what you actually did — and those two things are rarely the same.
Setting it up
- Prop the phone where it can see the whole trick
A tripod is ideal, but a shoe, a water bottle or a gym bag works. Frame the full move including take-off and landing — a cropped landing tells you nothing about why you fell out of it. Film side-on for rotation and shape, front-on for twist direction and drift.
- Open the replay screen on a laptop
Open trickatlas.com/practice on the screen you want to watch — a laptop propped on the bench, a tablet, or a TV browser. It shows a QR code and a six-character room code.
- Scan the code with the phone
Point the phone's camera at the QR code and open the link. The phone becomes the camera and the laptop becomes the replay. Both devices should be on the same Wi-Fi.
- Set the delay to your walk-back time
The delay slider runs from 1 to 12 seconds. Set it to roughly how long it takes you to land and look at the screen — four seconds suits a standing trick, eight or more if you have a run-up to walk back from.
Nothing is uploaded
The video goes straight from the phone to this screen. Our server only helps the two devices find each other — it never receives a frame, and there is no account, no upload and no storage. When you save a clip, your browser writes the file directly to this device. Nothing is kept, so there is nothing to delete.
If it won't connect
Both devices need to be on the same Wi-Fi, because they connect directly to each other rather than through a relay. Gym or café guest Wi-Fi that isolates devices from one another will block it — putting the laptop on the phone's hotspot is the usual fix. Room codes are throwaway and expire after 30 minutes; reload the page for a fresh one.
Questions
- Do I need to install an app?
- No. Both devices use the browser. The phone opens a link, the laptop opens a page — there is nothing to install and no account to make.
- Why do both devices need to be on the same Wi-Fi?
- The two devices connect directly to each other. TrickAtlas doesn't run a relay server that video could be bounced through, so the phone and the screen need a network path between them — the same Wi-Fi is the easy way to guarantee that. Gym guest Wi-Fi that isolates clients from each other can block it; a phone hotspot with the laptop joined to it works as a fallback.
- Is my video uploaded or stored anywhere?
- No. Video travels phone-to-screen and is never sent to the server. Clips are recorded and saved in your browser, onto the device you are watching on. Nothing is stored server-side, so there is nothing to delete.
- How long can the delay be?
- Between 1 and 12 seconds. Four is a good default for standing tricks; use more if you have a run-up to walk back from.
- Can I save the clips?
- Yes. You can save the last 5, 8, 12 or 20 seconds at any time, and the file downloads to the device you are watching on.
