IPSC overlay in OBS Studio — complete live broadcast guide

How to set up OBS Studio Browser Source for IPSC matches with PractiScore: overlay URL, per-stage scenes, safe areas, sponsors and dynamic real-time scoreboard.

General overlay guide

OBS Studio is the most widely used app for IPSC clubs and federations streaming to YouTube, Facebook and Twitch. With Scoring Services you do not edit scoreboards by hand: PractiScore tablets send every score, the match hotsite updates rankings and the transparent OBS overlay shows last shooter, leaderboard and top bar — all in real time, stage by stage, from warm-up to the final stage.

Set up Browser Source in OBS Studio

1. Prepare the match in PractiScore
Install ps-leaderboard (Installation guide), pair tablets and confirm the match appears at PractiScore management with active sync. Without data reaching the hotsite, the overlay will be blank.
2. Generate the overlay URL
At PractiScore management → Edit → Set up overlay, pick a stage and adjust sidebar, top bar, colors and logo in the preview. Copy the URL at the bottom of the wizard. IPSC variant: .../stage/{stage_id}/overlay.
3. Add source in OBS
In OBS: Add → Browser Source → paste the URL, width 1920, height 1080, disable “Control audio via OBS” and enable “Transparent background”. Place the source above the camera or video cut.
4. Use the scene panel
On the match hotsite, open the per-stage scene panel to switch between Full broadcast, HUD only, Break and Warm-up without editing the URL in OBS. Each stage has a “OBS URL” button to copy the correct link.
5. Test before going live
Use “Simulate scoring” in the overlay preview and check that the scoreboard at https://m.scoring.services/ updates. Only then start the YouTube or other platform stream — see PractiScore overlay YouTube.

vMix, Streamlabs and Prism

vMix and Streamlabs: use the same overlay URL in a Browser/Web source — transparent background, 1920×1080.
Prism (Android/iPhone): open the generated URL in the app for mobile lives with the same data.
Arena screen at the range: use kiosk mode at https://m.scoring.services/ alongside the live stream.
