OBS integration

OBS live caption browser source

4ALL live captions can appear in OBS through a configured browser source. Add the event’s production caption URL to an OBS Browser Source, size and crop it for the scene, and test text, transparency, styling, timing, and reconnection. The result is a visible overlay in the composed picture; it does not insert CEA-608/708 caption data into the encoded stream.

What it is

A production workflow, not a one-size-fits-all promise.

A browser source is useful when the program should always show captions as part of the visual composition. It is straightforward to place and style, but the production must preserve browser connectivity and enough on-screen space for readable text. If viewers must turn captions on or off in a downstream player, use an embedded-caption workflow instead.

Best for

  • OBS productions that need captions visible in the program composition
  • Streams where the producer controls caption placement and branding
  • Hybrid events using the same live caption source in a video scene
  • Teams that can monitor the browser source throughout the broadcast

Plan around

  • The OBS browser source produces open, visible captions rather than embedded closed-caption data.
  • Browser rendering depends on the production computer, network, scene configuration, and OBS state.
  • Cropping, scaling, CSS, or scene changes can make captions unreadable or hide them.

Capabilities and outputs

What the workflow actually delivers

The exact configuration depends on the event, audience destination, enabled features, and downstream production equipment.

Capabilities for OBS live caption browser source
CapabilityWhat it means in production
Browser renderingLoad the configured 4ALL caption view as a web source in an OBS scene.
Scene placementPosition, size, crop, and layer the source within the program composition.
Visible stylingUse the configured caption presentation while preserving sufficient contrast and readable line length.
Language selectionPoint the source at the event and language intended for the production graphic.
TroubleshootingCheck source URL, browser refresh, visibility, dimensions, network state, and scene order when text is missing.

Production workflow

From source audio to a verified audience output

  1. Step 01

    Prepare the caption source

    Configure the event, language, line behavior, and production caption view before opening OBS.

  2. Step 02

    Add an OBS Browser Source

    Paste the documented source URL and configure its dimensions, refresh behavior, and scene visibility.

  3. Step 03

    Design for readability

    Place the source in a safe area, preserve contrast, and test short, long, partial, and cleared text.

  4. Step 04

    Monitor the program output

    Watch the final composition and rehearse source refresh or recovery if the browser or network path fails.

Questions buyers and producers ask

Frequently asked questions

Can OBS display 4ALL live captions?

Yes. The documented workflow adds a configured 4ALL caption page as an OBS Browser Source and places it in the scene.

Are OBS browser-source captions closed captions?

No. OBS renders the web source into the visible program picture. Viewers cannot independently toggle that overlay as embedded CEA-608/708 captions.

Can the source show a translated language?

It can use a language that is enabled and available in the event. The producer should confirm the exact source URL and language before going live.

Why might captions not appear in OBS?

Common checks include the event state, source URL, network access, browser-source dimensions, crop, visibility, scene order, refresh state, and whether the chosen language is producing text.

When should I use 4ALL Encoder instead?

Use Encoder when the H.264 stream must carry embedded CEA-608/708 caption data rather than a permanently visible browser overlay.
