Add the subject graphic as a source in the scene that composes your program output. Use editable text or a prepared image for information that stays fixed; use a browser source when a suitable web page or data feed needs to update it. Place the graphic where it identifies the lesson without covering teaching content, then test the stream and recording separately. An overlay labels the picture—it does not by itself keep playback running or ensure recordings are saved.
Choose what the overlay needs to show
Keep the overlay focused on information that helps viewers identify the current lesson. Depending on your production, that might be the subject, course, lesson title, or instructor. Decide whether those fields are fixed for the whole broadcast or change as the schedule advances; that choice determines how you should update the graphic.
- Fixed information: a text source or prepared image is suitable when the label will not change during the relevant scene.
- Occasional changes: prepare clearly labeled text or image sources, or separate scenes, and have an operator select the correct one.
- Data-driven changes: a browser source can display a suitable web page or feed, but test its refresh behavior and confirm that your workflow actually supplies the data. A ready-made curriculum-schedule integration is not established here.
Add the overlay in OBS
In OBS, scenes assemble the program layout from sources such as text, images, windows, capture cards, games, and displays. Add the subject label to the scene used for the program output, and arrange it above the video or slides it should appear over.
- Identify the program scene. In OBS, select the scene that contains the lesson content and is used for the stream. If you have more than one output or scene, confirm you are editing the one viewers will see.
- Add a source for the label. Add a text source for editable wording or an image source for a prepared graphic. Use a browser source only if you have a page or feed designed to show the information. OBS’s overview explains the scene-and-source model, but does not provide a current step-by-step browser-source setup; check the labels and options in your installed OBS version.
- Enter the current subject details. Use an unambiguous label, such as the course and lesson name. If the information changes, decide who or what will update it and at what point in the schedule.
- Position and size it in the composition. Keep it out of the way of slides, demonstrations, captions, and other instructional material. Check it at the actual output resolution and over both light and dark content. No education-specific safe-area margin or standard size is established here, so do not treat an arbitrary pixel margin as a universal rule.
- Preview a representative lesson. Confirm the wording is correct, legible, and not clipped, and that the graphic remains visible above the intended sources.
For the exact current controls, consult the documentation for your installed OBS version. The OBS Project’s OBS Studio Overview Guide describes scenes and sources and notes that advanced output mode can configure streaming and recording independently.

Handle subject changes and recurring events
Manual updates
For a small number of subject changes, use labeled text or image sources, or make a scene for each subject. Assign an operator to select the correct label or scene at the transition, and rehearse the handoff so the previous topic does not remain on screen.
Web-fed labels
A browser source is an option when a page can provide changing information. Confirm how it refreshes, what happens if the page or feed is unavailable, and whether the displayed subject matches the lesson currently playing. The available documentation does not verify a turnkey schedule integration.

Saved graphics are not necessarily active graphics
Do not assume that saving a graphic means it will automatically be shown at the next event. Vimeo says lower-third graphics are supported in its in-browser production studio. For recurring virtual events, graphics are retained but do not automatically display on every stream; an operator still needs to show or hide them during the scene. See Vimeo’s instructions for adding graphics to a virtual event. Vimeo Livestream Studio also describes three graphics overlay channels and options to use a prebuilt template or create a custom graphic or layer; see Livestream Studio’s Graphics Overview. Controls and restart behavior differ by platform, so verify them in your own production setup.
Test recording and continuous playback separately
A correct overlay does not prove that a 24/7 stream will resume after an interruption or that a recording will be retained. Test the whole path you intend to use before leaving it unattended.

- Check the recording destination and retention process against your institution’s requirements; the platforms cited here do not establish a complete recording-retention design or uptime guarantee.
Choose a production route that fits your operation
Compare options by how the label changes, whether it is active after a restart, how streaming and recording are controlled, and whether the software, operating system, staffing, and security requirements fit your institution. OBS provides a scene-and-source workflow; Vimeo documents browser-studio lower thirds and recurring-event behavior; Livestream Studio documents its graphics channels and templates. These facts are not a complete head-to-head evaluation of education platforms, accessibility, recording retention, or service-level uptime.
A third-party 24/7 Playout Plugin for OBS describes playlist and rundown playback, loop mode, autostart or resume, and transparent browser overlays. Its repository identifies a Windows x64 release and recommends OBS Studio 32.x or a compatible version. It is optional third-party software, not a requirement for adding an overlay. Verify the current release, compatibility, security, and operational suitability before installing it; its feature description is not evidence of institutional uptime or security compliance. See the plugin repository.
