Use OBS scenes to change the picture during the broadcast, then add YouTube chapters to the archived video afterward. A scene switch changes what viewers see; it does not automatically create a chapter. Keep a timestamp log as you switch scenes, align it with the finished recording, and add the timestamps to that video’s description.
Scenes and chapters do different jobs
An OBS scene is a composition of sources sent to the stream, such as a dawn landscape, rain footage, or a fireplace. Switching scenes changes the broadcast’s visual output. YouTube chapters are timestamped sections of a video that viewers can use to navigate; for manual chapters, the timestamps and titles go in the video’s description. OBS’s overview explains scenes and transitions, while YouTube Help explains video chapters.
The workflow below is for making those two features work together on a 24/7 ambient stream. The sources cited here do not establish whether chapter markers display or update on the active live player, so add and verify them on the archived video rather than promising live-player navigation.
Prepare the visual changes in OBS
Build a scene for each visual state
- In OBS, create and name a scene for each distinct state you want viewers to see—for example, “Dawn lake,” “Rain on the window,” and “Fireplace at night.”
- Add the relevant image or video sources to each scene and check the composition in OBS before using it on air.
Scene names are useful to the operator and can later become chapter titles, but naming a scene does not add a timestamp or chapter to YouTube.

Choose the transition
Select a transition such as Cut or Fade and set its duration in OBS. For quiet ambient programming, a restrained fade may fit the material; that is an editorial choice, not a YouTube requirement. OBS documents built-in transitions and configurable quick transitions in its overview.
Choose how to trigger each switch
- OBS hotkeys: Assign a hotkey to switch to the intended scene. This is the built-in, direct option and does not require a hardware controller.
- Physical controller: A programmable controller can provide labeled buttons for scene changes. OBS’s plugins guide gives Elgato Stream Deck as an example of hardware communication through plugins. Plugin compatibility can vary by OBS version and platform.
For an unattended 24/7 schedule, do not assume that hotkeys or a controller will switch scenes automatically. The cited OBS material supports hotkeys, transitions, and hardware/plugin support, but does not establish a particular scheduled automation setup for this use.

Log each change while the stream runs
Record the elapsed time and a short, descriptive title every time you switch scenes. Logging as you go is less error-prone than reconstructing scene changes from a long recording later. A browser-based Stream Marker Tool describes capturing elapsed timestamps with titles for later use in a YouTube description; it is optional, not an OBS or YouTube requirement.
Keep the log in a form you can correct. Your live-session clock may not match the archived video’s timeline if recording starts late, the video includes a pre-roll, the beginning is trimmed, or the recording uses a different zero point.

Add and verify chapters on the archived video
- After the live session, open the archived video and compare each logged scene change with the actual recording. Correct timestamps to match the video as viewers will watch it.
- In YouTube Studio, edit the archived video’s description and add the timestamp/title lines. YouTube’s manual chapter rules require the first timestamp to start at 00:00, at least three timestamps in ascending order, and chapter spans of at least 10 seconds.
- Save the description and check the video page to confirm YouTube displays the chapter bar. If it does not, recheck the timestamp format, first marker, ordering, and minimum chapter span against YouTube’s current chapter guidance.
Example format, with illustrative labels and times only:
00:00 Dawn lake 02:15 Rain on the window 04:30 Fireplace at night
Replace these sample times with the actual scene-change times in your recording. The description labels support navigation; they do not trigger or control OBS’s visual transitions.
