Getting started
What is Veritas?
Veritas records badminton practice from a phone on a tripod and generates a stat sheet with rallies, shot types, speeds, and court coverage within about ten minutes.
Do I need to buy hardware?
No. Use your own phone. You'll need a tripod or mount to position the camera 2.5 to 3 metres up.
Is this for academies or solo players?
Both. Academies get player profiles, invite links, and the ability to record for players. Solo players record their own sessions and get the same analysis.
Which phones work?
Any recent iPhone or Android that can record 1080p at 60fps. An ultra-wide lens is helpful but not required.
How do I sign in?
Google login or phone number plus SMS code. No passwords, which matters when setting up accounts for multiple players.
Setup and recording
Why does the camera need to be so high?
Height separates the players and far court in the image. Too low and the far court becomes too few pixels, degrading tracking and shot classification. 2.5 to 3 metres works best.
Why won't the app let me record?
Recording requires correct court geometry because all downstream measurements depend on it. The app tells you what to adjust: move back, mount higher, clean the lens, or tap corners again. You can override and record anyway, but analysis will be less reliable.
What if the court isn't detected automatically?
Tap the four corners yourself on the preview. Unusual line colors, strong glare, and hidden baselines usually cause automatic detection to fail.
What if someone bumps the tripod?
Motion sensors detect the bump and the analysis pipeline recalibrates from that moment. A nudge won't ruin the session, but a serious knock is worth re-framing.
Why is video stabilisation off?
Stabilisation subtly warps the image to smooth motion, which is fine for watching but breaks the geometric measurements that rely on a fixed image-to-court relationship.
How long can a session be?
Around thirty minutes is the standard working length. Longer recordings work but take proportionally longer to process.
What if I lose signal during upload?
Nothing is lost. Uploads are chunked and resumable. They continue in the background, survive the app being closed, and pick up from the last completed chunk.
Accuracy and data
How accurate is shot classification?
Accuracy depends on capture quality. Every session includes shuttle detection rate, average shot confidence, and frames analysed. A well-framed session on a well-lit court is materially more accurate than a poorly framed one, and the stat sheet shows you which you got.
Which shots can it recognize?
Nine types: serve, smash, drop, lift, drive, block, push, toss, and net shot. Each gets a count, percentage of the session, and confidence score.
How are shot speeds calculated?
Court geometry maps the image to real-world coordinates. Shuttle trajectories are fitted in real court space, so speed in km/h is measured from actual distance over actual time, not from screen appearance.
Does it work for doubles?
Yes. Sessions can be marked as 1v1, 1v2, 1v3, drills, or a match, and the court heatmap uses full doubles dimensions. Per-player stats are most reliable with fewer players.
Will it identify technical errors?
No. Veritas measures what happened and gives that to the coach to interpret. Coaches are better positioned than any model to analyze technique.
Does it work for other sports?
Not yet. Everything is built specifically for badminton. We prefer to be genuinely good at one sport rather than approximate across several.
Academies and pricing
How do players join an academy?
An admin generates a single-use invite link. The player opens it, sees which academy they're joining, and claims their profile. Links expire and can't be guessed.
Can coaches record for players?
Yes. Select the player before recording and the session goes to their profile. This is how most academy sessions get captured.
What does it cost?
Academy pricing is still being finalized. Contact us through the contact page to discuss your setup.
Privacy
Is video stored?
Yes. Session video is uploaded and stored for analysis and highlight retrieval. The Privacy Policy covers retention periods and deletion requests.
Who can see a player's sessions?
The player and their academy only. Sessions are not public and not shared between academies.
What about recording minors?
Academies working with junior players must get parent or guardian consent before recording. The Privacy Policy covers how this data is handled.
