Resolve missing, opaque, stale, cropped, soft, delayed, or incorrectly layered browser captions.
Best for: Event producers, display operators, accessibility leads, broadcast/AV engineers, web teams, and authorized remote operators.
Before you start
Availability depends on event access, plan entitlements, destination enablement, language configuration, and supported browser/display/network behavior.
- Use the correct event and final source/target language configuration.
- Know the physical or web destination, resolution, audience, privacy level, and monitoring owner.
- Test the final receiving screen, embed, graphics path, or operator device—not only the setup preview.
Troubleshooting steps
- Check the URL. Confirm it is the current event Closed Captions destination and correct language.
- Check event/source. Verify fresh captions in Live Setup.
- Check browser source. Visibility, scene, source refresh, dimensions, FPS, custom CSS, and network.
- Check alpha and layer order. Place above program video and preserve transparency.
- Check scaling. Use native program resolution and avoid multiple resizes.
- Check delay. Compare source segment, destination, OBS, encoder, and platform timestamps.
- Check sleep/reconnect. Disable source-machine power saving and rehearse browser-source restart.
- Capture final program evidence. Do not rely on the source preview.
After the fix: The intended audience or operator receives the correct event, language, styling, and control level with a documented reconnect and fallback path.
Confirm the fix
- The root layer—4All, browser source, compositor, encoder, or receiver—is identified and corrected.
If the problem continues
Caption source visible in OBS preview but not program
Check scene/program bus and layer visibility.
Stale after scene change
Review refresh-when-active and page lifecycle.
Soft text
Match source/output resolution and avoid resampling.
Escalation and safety
- Do not reveal stream keys or output URLs in evidence.
- Coordinate scene/source restart on air.
- Maintain a fallback graphic or Program Display path.
