You can change prerecorded content without ending your YouTube live stream by switching what OBS sends while keeping the same encoder session connected. Add the videos as media sources or a playlist, arrange them in scenes, and change the active scene from OBS.
That keeps the live session running, but it does not guarantee a perfectly gap-free picture or sound. A file may need to load, decoding may briefly lag, or audio may change unexpectedly, so rehearse the exact sequence and monitor the output.
What “without interrupting” means
There are two different things people mean by an uninterrupted stream. One is that the YouTube live event and encoder connection remain active; the other is that every viewer sees continuous, flawless video and audio at every instant. The first is the workflow you can control. The second depends on source loading, the files, OBS configuration, the computer, and how YouTube delivers playback to each viewer.
YouTube receives a feed from your encoder using a stream URL and stream key. In OBS, scenes and sources determine what appears in that feed. A scene change changes the programme being sent; it is not the same operation as disconnecting the encoder or ending the event in Live Control Room. YouTube’s encoder setup guidance explains how an encoder connects to a live stream.
This distinction matters if, for example, you run a bhajan stream and want to move from a morning prayer video to a song segment. You can prepare both segments in OBS and switch the output while YouTube continues receiving one stream. Viewers may notice a brief visual or audio artifact at the change, but the event need not be ended and started again simply because the content changes.
Treat the transition as a change of programme, not a promise about every viewer’s playback. Some viewers may also be watching with DVR paused or rewound, so they will see earlier content until they return to the live edge. That alone does not mean your encoder stopped.
Keep one encoder session connected
First set up the YouTube event and connect OBS to it. In YouTube Studio’s Live Control Room, create or select the encoder stream and copy the stream URL and stream key into the stream settings in OBS. Keep those connection details unchanged while you switch the content. The key is connection information for the encoder feed; it is not a label for a particular video or scene.
Once OBS is sending the feed, leave that session connected as you change sources or scenes. You do not need to stop the OBS stream, create a new YouTube event, or paste another key for each prerecorded file. Stopping the feed or ending the event is a separate action, reserved for when you actually intend to finish the broadcast or need to recover a connection problem.
Before the first live run, confirm that OBS is sending to the intended event, not a test event or an old stream configuration. YouTube’s encoder guidance and the OBS Studio overview describe the separate roles of the live connection and the content layout. In practice, keep the Live Control Room open during setup so you can check that it is receiving the feed.
If you want an always-on channel, remember that switching the video in OBS does not make the computer or encoder session independent of your machine. The application still has to run and keep sending. For a different operating model where the computer can be switched off, see how to keep a YouTube stream live after switching off the PC in India. That is a separate question from changing content within an active OBS session.
Add files as Media Sources or a VLC playlist
For an individual file, add an OBS Media Source and point it to the local video. OBS documents common formats such as MP4, MOV, MKV, AVI, and WebM in its Media Sources guide. Check the source’s playback options rather than assuming that every file will behave the same way.
The useful choices depend on how you intend to use the clip. If it should begin at the start every time it becomes active, configure it to restart on activation. If it should repeat continuously, enable looping. If you need a blank or another scene after playback ends, decide whether the source should hide when playback finishes and test that behaviour. The labels and available controls can change between OBS versions, so check the current source properties in your installation.
A source that closes its file while inactive can use less memory, but OBS warns that reopening it may create a short delay when it is shown again. Keeping it loaded may avoid that particular reload step, though it is not a guarantee against a glitch. If you use a still image or holding scene while another file loads, put it in the sequence deliberately and rehearse the change rather than assuming it will appear automatically.
If you need several videos to play in order without an operator selecting each one, OBS also offers a VLC Video source. Add the files to its playlist and choose the intended order; the source has loop and shuffle controls. VLC must be installed, and OBS notes that its architecture should match the OBS installation: for example, 64-bit OBS requires 64-bit VLC. Test what happens at the end of one item and the start of the next using the files you intend to broadcast.
| Arrangement | Useful when | Check before going live |
|---|---|---|
| Separate Media Sources | You want to select one video at a time or place each clip in its own scene | Restart, loop, end behaviour, and any reload delay when a source becomes active |
| VLC Video playlist | You want an ordered set of clips to advance as a playlist | VLC installation and architecture, playlist order, end-of-file behaviour, and audio between items |
| Scenes containing sources | You want named programme segments and deliberate manual changes | The output scene, transition choice, and the exact order of your rehearsal |
For a single prayer video followed by a separate discourse, individual sources make it clear which segment you are selecting. For a long sequence of study ambience clips, a playlist can reduce manual selection, but it also means you should carefully check the next-item behaviour and the intended order. Neither arrangement removes the need to test on the machine that will run the stream.
Organise content into scenes
In OBS, a scene is an arrangement of sources that forms the current output. You might create a scene for an opening slate, one for each prerecorded programme, and another for a holding image. Give scenes names that identify their content and order, such as “Morning prayer” and “Talk segment”, rather than “Scene 1” and “Scene 2”. Clear names reduce the chance of selecting the wrong item during a live handover.
You can put one Media Source in each scene, or organise several sources in a scene if they need to appear together. Check the visibility state of every source and make sure the intended video and audio are part of the scene. In a small business channel, for example, you might use one scene for a product loop and another for opening hours. The change should replace the intended content, not reveal a desktop, an empty canvas, or an unintended source underneath it.
Set up transitions deliberately. OBS provides scene transitions, and its sources guide covers how sources appear in scenes. A cut is a direct change; a fade changes the picture over a chosen transition. A fade may suit a devotional or ambience channel, while a direct cut may make sense between clearly separated news items. The right choice is about presentation, not a guarantee that the files will decode without a pause.
Hotkeys can help when you need to change scenes without reaching for the mouse, but they need careful setup. Choose keys that are unlikely to be pressed accidentally, and practise them with the same keyboard and other applications you will use during the broadcast. If a transition is tied to an operator’s timing, a visible scene list and a short run sheet can be more reliable than trying to remember an improvised sequence at night.
A scene plan also clarifies what should happen if a clip finishes early. Decide whether the next scene is another video, a holding image, or a manually selected item. If the sequence must proceed without an operator, a playlist may suit it better; if each programme has a different start time or needs a spoken introduction, separate scenes provide more control. For a deeper look at transition choices, see OBS scene transitions for a 24/7 pre-recorded YouTube stream.
Switch scenes while the encoder stays live
Once the sources and scenes are prepared, start the YouTube event and connect OBS as you normally would. Check the OBS preview before changing scenes. When you select the next scene, OBS changes the content in the outgoing feed while its encoder connection remains in place. Do not click a control to stop streaming or end the event if your goal is only to move to another prerecorded segment.
For a planned manual change, have the next scene ready before the handover. Confirm its name, then use the scene list or a configured hotkey. Watch the preview and the programme output after the change. A preview can help catch a wrong selection, but the audience-facing output and the Live Control Room are what you need to verify once the stream is running.
For a playlist, distinguish changing scenes from changing playlist items. A VLC Video source can advance through its configured files, while a scene change selects a different arrangement of sources. If you have both mechanisms in one setup, test their interaction: a playlist may continue, restart, or be affected by visibility depending on its source settings. Keep the sequence as simple as the programme allows.
If more than one person helps run the channel, agree on who controls the scene changes and who watches the output. A simple cue such as “switch after the closing chant” is clearer than an approximate time if clips vary in length. You can note the intended scene order alongside the file names. This is especially useful for local news loops and community channels where segments are updated between broadcasts.
The workflow is local to the encoder: the same connected OBS session sends the new scene to the same YouTube stream. It is not necessary to create a separate event for each file. If you are weighing a different way to keep an archive playing continuously, streaming a podcast archive as a continuous YouTube livestream from a VPS covers a different operating approach; it does not change the basic OBS distinction between the feed and its content.
Understand possible brief transition glitches
A live session can remain connected while a transition still produces a brief black frame, frozen picture, silence, or overlap. OBS documents that closing an inactive media file can mean a delay when it is shown again. File decoding, audio routing, a busy computer, or a source that is not active as expected can also affect what you see. The official documentation does not give a universal duration for these effects or promise frame-perfect changes across every file and setup.
Check the source first if a transition looks wrong. Confirm that the file path is still valid, that the source is visible in the scene, and that restart-on-activation or looping is set as intended. If a source was set to close while inactive, test whether leaving it loaded changes the observed delay. Make only one change at a time so you can tell whether the result improved.
For silence or overlapping audio, inspect which sources are producing sound in each scene and how the audio changes at the transition. Test with representative speech, music, and quiet passages; an audio meter moving in OBS does not prove that the audience hears the intended mix. There is no single audio routing setting that suits every scene design, so verify the actual output rather than copying a setting from an unrelated setup.
Performance matters too. A high-resolution file, several active sources, or other work on the same computer may make a transition less predictable. Close unrelated applications and test on the machine you will actually use, with the same files and scenes. If the channel is intended to run overnight, do a rehearsal long enough to cover the sequence and any loop or playlist behaviour that matters, rather than testing only the first switch.
Avoid treating an apparent pause on one viewer’s screen as proof that the YouTube event ended. The viewer may be behind the live edge, their playback may be buffering, or the transition itself may have been visible. Check the encoder and Live Control Room before restarting anything. For practical context on reducing machine load, see how to lower CPU use on a 24/7 kids’ cartoon stream, while remembering that every computer and media set needs its own test.
Verify the YouTube output
Before going live to the audience, preview the feed in YouTube Live Control Room and perform a test with the actual files. YouTube recommends testing and monitoring the stream; its live encoder settings guidance is a useful reference for checking the feed. Use a representative transition that includes motion and sound, not only a static opening frame.
During a rehearsal, observe both the OBS programme output and YouTube playback. Check that the intended scene appears, the picture moves, speech or music remains audible, and the next clip starts where expected. If possible, view the watch page on another device or connection. That can reveal playback issues that are not obvious in the encoder preview, though it will not reproduce every viewer’s network conditions.
While live, keep the Live Control Room available and monitor stream health. If a transition fails, note what happened and whether OBS still appears connected before taking action. A switch to a fallback scene may be appropriate if the content itself is missing; ending the event is a separate decision. YouTube’s advice is to test and monitor rather than assume that a successful preview guarantees every later transition.
When the broadcast is finished, end the event in Live Control Room and stop the encoder feed as directed by YouTube. That is the orderly end of the stream, not a step needed between prerecorded videos. YouTube Help says streams under 12 hours are automatically archived; check its current live streaming guidance for the latest handling and operational details.
If managing the computer, media files, and overnight monitoring is the pain point, StreamNeo removes the need to keep your own computer running for the video feed: you upload the file once, connect your YouTube stream key, and the channel can continue from there. It is YouTube-only, so it does not replace an OBS workflow when you need to switch scenes manually during a production.

FAQ
Do I need to end the YouTube stream to change videos?
No. If OBS is connected to the YouTube stream, you can change the content by switching its active scene or using a configured playlist. Ending the event is not required for a content change.
Will viewers see a completely smooth transition?
Not necessarily. The live session can stay connected even if a source takes time to load or a brief visual or audio artifact occurs. Rehearse the exact files, settings, and transitions you plan to use.
Should I use Media Source or VLC Video?
Use Media Source for a file you want to place and control directly, particularly when each segment has its own scene. VLC Video is useful for an ordered playlist, but it requires VLC and its behaviour should be tested with your files.
Why does one viewer appear to be watching the old video?
The viewer may have paused or rewound with YouTube DVR and may be behind the live edge. Check the Live Control Room and encoder output to determine whether the stream itself is still live.
