Keep the same YouTube live event and encoder connection running while you change the active gaming video inside OBS. Prepare each rerun as an OBS scene, then switch scenes with a transition or hotkey instead of stopping the encoder.
This can reduce the interruption caused by changing files, but it is not a guarantee of a gap-free handover. The exact result depends on how your OBS version handles the media source, whether the next scene is ready, and how YouTube receives the outgoing feed.
Keep one YouTube live event and encoder connection
A YouTube live stream has two parts that are easy to confuse. The live event is the broadcast created in YouTube Studio. The encoder is the software that sends your video and audio to that event. OBS is acting as that encoder in this workflow.
Create or schedule the event in YouTube Studio, then copy the stream URL and stream key into OBS. YouTube describes the stream key as the credential that allows the encoder to send the feed. Keep those values in the same OBS profile while the rerun is running. The YouTube encoder setup instructions explain the connection and preview process.
The important change happens inside OBS, not in YouTube Studio. You leave OBS connected and sending a live signal, while changing which scene supplies the video. YouTube continues receiving one encoder feed rather than seeing a sequence of separate connections.
This approach also keeps the broadcast identity in one place. Viewers use the same watch page, chat, event details and live URL. You do not need to create a new event every time one gaming video ends.
Do not treat the stream key as a video selector. Changing the key, server or event during a rerun is a connection change, not a content change. If the key is rejected or the stream is not publishing, use the stream key troubleshooting guide before investigating scene changes.
YouTube's encoder guidance says that ending a stream involves stopping the content from the encoder. That is why stopping and restarting OBS should not be your normal way to move from one rerun video to the next. It may be necessary during a fault, but it is the wrong routine for a planned changeover.
Prepare each rerun as an OBS scene
Create a simple scene structure before you start the broadcast. For example, you might have one scene for Gaming Video A, another for Gaming Video B, and a third for a short holding screen. Each scene can contain the media source, audio source and any overlay that belongs with that video.
The purpose is not to make the layout complicated. It is to make the intended change visible and repeatable. If you have five videos, five clearly named scenes are easier to inspect than one scene containing several sources whose visibility must be changed manually.
Use names that describe the content rather than the file name generated by an editing programme. Minecraft episode 04 tells you more at two in the morning than export_final_7. If you are changing videos without being present, add a note outside OBS showing the order in which the scenes should be used.
Check the following for every scene:
- The correct video file is selected.
- The source is visible in the scene preview.
- The game audio can be heard on the OBS mixer.
- Any microphone, music or overlay source behaves as intended.
- The canvas and output resolution do not change unexpectedly.
- The scene does not expose a desktop, notification or private window.
A useful arrangement is to keep common elements in a shared way where your OBS setup supports it, while keeping the changing video source easy to identify. Avoid changing several unrelated settings at the exact moment of the handover. A scene switch should select the next programme, not also alter your encoder, audio routing and output settings.
If your videos have inconsistent dimensions or frame rates, prepare them before building the scenes. The video preparation guide for a 24/7 YouTube loop covers the practical checks that make a long rerun easier to manage. Consistent files do not promise a seamless switch, but they remove avoidable surprises.
Remember that a scene is an OBS arrangement, not a YouTube playlist item. OBS may handle a media source differently depending on its version and configuration. Do not assume that naming scenes in sequence will make them advance automatically.
Switch the active scene with a transition or hotkey
OBS provides scene transitions and quick transitions for changing the active scene. You can also configure a hotkey for a particular scene. The OBS Studio overview guide documents the main scene and transition controls.
For a manual change, select the next scene and watch the programme output rather than relying only on the preview. If you use a transition, choose one you can identify clearly while testing. A short fade may be easier to observe than a complex effect, but the correct choice depends on the material and the look of your channel.
A hotkey is useful when you want the change to happen without reaching for the scene list. Assign a different, memorable key to each planned scene, or use a transition hotkey where that suits your workflow. Check that the shortcut is not already used by a game, browser or other application. If OBS is not the active window, confirm how your configured shortcut behaves before leaving it unattended.
A normal keyboard shortcut is enough for most setups. A programmable macro keypad can make repeated changes more convenient, but it is not required and should not be treated as a fix for an untested OBS configuration. First prove that the scene hotkey works reliably from the keyboard.
The change should be made while OBS remains connected to YouTube. Do not press a stop button in OBS, end the event in YouTube Studio, or replace the stream key simply because the programme content is changing. Those actions affect the live connection rather than selecting the next video.
There may still be a visible transition, a moment of frozen video or a brief change in audio while the next source becomes ready. Describe the goal accurately: you are keeping the encoder connection and live event active while reducing the interruption caused by a content change. No official source cited here establishes that every OBS configuration will switch videos without a gap.
Do not stop and restart for every video
Stopping OBS after each file creates several separate operations: the encoder stops sending, YouTube processes the change, OBS starts again, and the new output must be recognised. Each operation adds another point at which the viewer may see an interruption or a waiting screen.
It also makes the live event harder to manage. A scheduled event may move through different states, the preview may need to be checked again, and viewers may return to a page that is no longer receiving the expected feed. The exact behaviour can vary with the event and account settings, so do not design a nightly workflow around repeated starts and stops.
Use a stop and restart when you are repairing a genuine fault, changing the broadcast itself, or deliberately ending the event. Do not use it as the normal equivalent of pressing “next”. For a planned rerun change, the normal sequence is:
- Leave the YouTube event active.
- Leave OBS connected and sending.
- Select the next prepared scene.
- Apply the configured transition or hotkey.
- Watch the programme output and YouTube preview.
- Confirm that the new video and audio are present.
This is also why the OBS versus FFmpeg comparison for a 24/7 radio station is useful background, even though this article focuses on OBS. The choice of encoder affects how you arrange and supervise content. It does not turn a stop-and-start change into a continuous one.
YouTube says streams under 12 hours are automatically archived. That is an archival detail, not a method for switching videos and not evidence that a particular OBS media source will advance correctly. Treat the live event and the recorded archive as separate concerns.
Verify media-source behaviour in your OBS version
The most dangerous assumption in an unattended rerun is that a media source will behave like a playlist player without further configuration. Your installed OBS version, source settings and scene arrangement determine what happens when a file reaches its end or when a scene becomes active.
Before choosing an automation method, check the controls shown in your own OBS installation. Look specifically at what happens when a media source ends, when its scene is hidden, and when the scene becomes active again. If a setting appears to restart, loop or advance media, test it rather than relying on its label alone.
The official OBS overview explains scenes, sources and transitions, but it does not establish one universal set of automatic playlist or restart behaviours for every version and arrangement. The same setting may behave differently depending on whether the source is always active, is hidden in another scene, or is reloaded when the scene changes.
Keep a written record of the behaviour you observe. For example:
| Test | What to observe | Why it matters |
|---|---|---|
| Scene A reaches the end | Does it stop, hold the final frame, restart or show another state | Tells you what viewers see before the next change |
| Scene B becomes active | Does its file start from the beginning or continue from an earlier position | Confirms whether a scene switch is a reliable next-item action |
| Scene B is hidden and shown again | Does the source reset or retain its position | Shows whether scene visibility affects the file |
| Two scenes are changed repeatedly | Does video and audio remain consistent | Exposes behaviour that a single test can miss |
| OBS reconnects after a fault | Does the intended scene remain selected | Helps you plan recovery without promising automatic repair |
Do not publish a playlist schedule until these results are clear. If your OBS version does not provide the behaviour you need, use a manual scene hotkey, investigate documentation for that specific version, or choose a different workflow. The right answer is the one you can observe and repeat, not the one suggested by an unverified checkbox.
For a fully unattended channel, also consider how someone will know that a file has ended or a scene has failed. A monitoring plan is part of the workflow. It may be as simple as checking the YouTube preview at planned times, provided you understand that a preview check is not a guarantee about every viewer's playback.
Test the change before relying on automation
Test privately or with an unlisted event before using the workflow on a public channel. You need to inspect both sides: the OBS programme output and the viewer-facing YouTube playback. A scene that looks correct in OBS may have an audio issue, an unexpected overlay or a delay before it appears on YouTube.
Start with two short test files rather than your full overnight collection. Put them in separate scenes and make several changes in both directions. Test a change near the end of a file, a change while audio is active, and a change after OBS has been left running for a while.
Use a second device or browser profile to watch the YouTube output. Keep the YouTube Studio control room open on the operator device. Check that the event remains live, the preview is updating and the viewer device eventually shows the intended scene. YouTube defines live latency as the delay between capture and playback, so a viewer may see the switch later than you do in OBS.
Do not judge the result from one frame alone. Watch the audio meter, the programme output and the viewer playback through the whole handover. Listen for a missing first second, doubled audio, a frozen last frame or a scene that appears before its media is ready.
If you change latency settings, test again. YouTube notes that lower latency can involve more buffering, while higher latency gives playback more time to receive data. These settings affect the viewer experience; they do not control OBS scene changes or make a media source advance.
You can also test DVR behaviour if your audience may pause or rewind. YouTube's DVR option affects how viewers interact with the live playback. It does not make the live event switch scenes, and a viewer who has rewound may see the change at a different point from someone watching live.
Only after this test should you decide whether a manual hotkey is sufficient or whether a version-specific automation method is worth maintaining. Automation reduces routine effort only when its failure modes are understood.
Check that the live event remains active for viewers
During the real broadcast, check the event rather than assuming that a successful OBS action reached YouTube. In YouTube Studio, confirm that the event is still the intended one and that the incoming preview is moving. From a separate viewer connection, check the watch page, picture, audio and chat availability if chat is part of your channel.
A practical changeover checklist is:
- Note the current scene before switching.
- Confirm the next scene name before using its hotkey.
- Apply the transition once, not repeatedly while waiting for playback.
- Check that the OBS programme output shows the next video.
- Check that YouTube's preview is receiving the new content.
- Listen for the expected game audio.
- Confirm the public watch page has not moved to an ended or different event.
- Record the time and result if you are testing an unattended schedule.
If the bitrate drops, a scene change may appear to have failed when the underlying problem is the connection or encoder output. The YouTube live bitrate troubleshooting guide helps separate delivery problems from scene and media-source problems.
Keep recovery simple. If the next scene does not appear, switch back to a known-good holding scene while the encoder remains connected, if that scene is available and tested. Then inspect the source and audio rather than repeatedly pressing the same hotkey. If OBS itself has stopped sending, follow YouTube's encoder recovery process and accept that this is a fault recovery, not a normal content switch.
For a computer-based setup, power, sleep settings and updates matter as much as the scene list. A machine that sleeps or restarts cannot perform a planned handover. If keeping a computer on overnight is the part that worries you, read about alternatives to running a computer continuously for a YouTube stream. The same questions still apply: how does the content change, how is the live event checked, and what happens when something stops?
A cloud workflow such as StreamNeo can remove the need to keep your own computer running for this particular upload-and-stream arrangement, but you should still verify the actual content schedule and viewer handover before relying on it for an unattended channel. No hosting arrangement removes the need to check that the video, live event and channel settings are suitable for your use.

FAQ
Can I change the YouTube video without creating a new live event?
Yes, the intended workflow is to keep the same YouTube event and encoder connection active while changing the content inside OBS. Prepare the next video as a scene and switch to it with a tested transition or hotkey. The result can still vary by media-source behaviour and delivery delay, so test it before using it publicly.
Should I stop OBS when one gaming video ends?
Not as the routine change method. Stopping the encoder ends the outgoing content, which conflicts with the aim of keeping one continuous live event. Stop and restart only when you are recovering from a fault, changing the broadcast deliberately or ending the event.
Will an OBS media source automatically play the next file?
Do not assume that it will. Check the controls and behaviour in the OBS version you actually use, including what happens when a source ends, is hidden or becomes active again. The official documentation does not establish one universal automatic playlist behaviour for every setup.
Does YouTube latency make the scene switch gap-free?
No. Latency changes how long it takes for viewers to see the encoder output and can affect buffering, but it does not operate OBS scenes or prepare the next file. A lower delay may suit an interactive channel, while another setting may be more tolerant of delivery variation; test the viewer experience rather than treating latency as a switching solution.
