If you produce livestreamed events - panel discussions, conferences, AMAs, fan Q&A streams - you have probably hit the same problem twice: the audience wants a way to ask questions, the chat surface they have is messy, and your producer needs the curated questions to appear on the broadcast itself, not buried in a tab on a different machine.
The fix is a Q&A overlay running as an OBS browser source, fed by your moderator's curated queue. Here is how to set it up with Q&A Events. The same approach works in vMix, StreamYard or any tool that accepts a browser source URL.
What you need before you start
- A Q&A Events Pro tier event - the streaming overlay URL is included on Pro.
- OBS Studio (free, cross-platform) or any tool that can render a browser source.
- The audience-facing widget URL (so attendees can submit questions).
Step 1 - get the overlay URL
In your Q&A Events dashboard, open the event you are about to broadcast. The embed panel exposes two URLs:
- Audience widget - the URL attendees use to submit and vote on questions. Embed this on your event page or share it as a QR.
- Streaming overlay - the URL OBS will render. Transparent background, sized for broadcast canvases.
Copy the overlay URL.
Step 2 - add a browser source in OBS
- Open OBS, select the scene you broadcast from.
- Under Sources, click the + button and choose Browser.
- Name the source something obvious like "Q&A overlay" and click OK.
- In the properties dialog: paste the overlay URL into URL, set Width to
1920and Height to1080for a standard 1080p canvas. Click OK.
Step 3 - position the overlay
The overlay defaults to a transparent background with the active question rendered in a clean card. Resize and drag the browser source within OBS to position it - typical placements are:
- Lower-third strip for talking-head streams. Position the source along the bottom 25% of the canvas.
- Side panel for split-screen layouts. Position alongside the camera feed.
- Full-screen reveal for poll results. Crossfade in when the producer wants the audience focus on the result.
Step 4 - decide between manual and auto modes
Q&A Events offers two overlay modes:
- Auto. Newly approved questions push to the overlay automatically. Good for casual streams where you want the queue to feel alive without producer intervention.
- Manual. The producer picks which question shows next, and when. Good for high-stakes broadcasts where every reveal needs to be deliberate.
Switch modes from the moderator dashboard mid-broadcast if needed.
Step 5 - smoke-test before going live
Before going live, run a five-minute internal test:
- Submit a fake question from your phone.
- Approve it from a second browser tab acting as the moderator.
- Confirm it appears in the OBS preview within two seconds.
- Push a poll, confirm the result reveal lines up with your stinger or transition.
Producer-friendly tips
- Pin the overlay source across scenes so it persists when you cut between camera angles.
- Use a hotkey in OBS to toggle the source visible/hidden - lets you hide the overlay during host-only segments without unloading the page.
- Pair with a poll trigger. Have the moderator queue a poll a minute before you hit a planned segment break - the natural lull becomes the reveal moment.
- Cache the page. If your venue Wi-Fi is dodgy, the browser source caches the last frame even when offline. Worth knowing if you have flaky uplink.
Beyond OBS
The same overlay URL works in any browser-source-capable tool: vMix, StreamYard, Restream Studio, even older XSplit setups. Most studios support transparent browser sources natively now.
If you run streaming events regularly, the broadcast workflow is the difference between Q&A feeling like an awkward chat-side feature and Q&A feeling like a proper segment with reveals, polls and producer-controlled timing.
