If you want different footage on the same 24/7 YouTube live video, keep the encoder connected and change the content it is sending: use an OBS Media Source for one file, or switch to a scene prepared with the next file. This changes what viewers see within the existing feed; it does not create a separate YouTube broadcast, and no source change can guarantee a gap-free transition on every setup.
If you mean a distinct live video on YouTube while the existing 24/7 broadcast continues, that is a different operation involving separate broadcast resources. First decide which outcome you want, then use the matching workflow below.
First decide what “online” means
A live stream has two related parts. Your encoder sends a video feed to YouTube using a stream URL and stream key; YouTube associates that feed with a live broadcast viewers can watch. YouTube describes the stream key as a credential that tells the encoder where to send video and lets YouTube accept it. Treat it as sensitive, much like a password. See YouTube’s instructions for setting up an encoder stream.
In everyday language, “keep the stream online” can mean either keeping that same broadcast and watch page active while changing the picture, or keeping it active while launching another live video with its own broadcast. The first is a change to the content being sent through the existing encoder feed. The second creates a distinct broadcast. A scene change in OBS is not a substitute for the second operation.
For a devotional channel, for example, changing from one bhajan video to another can mean replacing the visible media source in the existing scene. Viewers are still watching the same live video. If instead you need a separate scheduled event or interview live video alongside the 24/7 channel, plan for a second broadcast workflow rather than expecting a changed OBS scene to create another YouTube watch page.
The distinction also matters when a transition goes wrong. If you stop the encoder from sending content, YouTube’s guidance treats that as ending the stream. Do not stop the encoder or end the broadcast if your intention is to retain the current live video. You can read more about recovery planning in what to do after a continuous stream’s encoder crashes.
Change the active Media Source
Use an OBS Media Source when the next item is one local video file. Prepare the file before changing the live scene: check that it opens, that its picture and audio are as expected, and that OBS can access its location. OBS documents support for common formats including MP4, TS, MOV, FLV, MKV, AVI, GIF and WebM, and provides a Loop property for repeating a file. Check the OBS Media Sources documentation for current details.
Keep the YouTube service, stream URL and stream key configured as they are. The goal is to change which media is visible in the scene while the encoder continues sending its feed, not to reconnect or reconfigure the destination. In OBS, the source is the item that supplies media; a scene is the arrangement of sources that the encoder outputs. Make the content change within that production setup rather than stopping the stream to upload or set up the next file.
A practical preparation method is to add the next file as a source in advance, with a clear name such as “Morning bhajan” or “Next loop”. Confirm its visibility and placement in a non-live test scene before relying on it. When it is time to change, make that source visible in the active scene or use the scene-switch workflow described in the next section. Exact control positions depend on your OBS layout and configuration, so do not assume a particular button sequence without checking your own setup.
If you are replacing a file path in an existing Media Source rather than preparing another source, remember that the source depends on a file available to the computer running OBS. A file moved, renamed or stored on a disconnected drive may not be available when OBS needs to read it. Keep a stable copy where the streaming computer can access it, and verify the new file before changing the live output.
A Media Source is a straightforward choice for one clip, but it is not a broadcast scheduler. You still need to manage which content is active and decide what should happen when the file ends. If the same clip should repeat, use the source’s loop option and check the end-to-start transition locally. For multiple items that should play in sequence, a playlist source is more appropriate.
Switch to a scene prepared with the next video
Scenes are useful when the change includes more than a file. You might have one scene with a still background, title and current video, and another scene laid out for the next programme. Set up the next scene before going live, add and test its sources, and confirm that its audio and framing are suitable. When it is time to move on, switch the active output to that prepared scene while OBS continues streaming.
This keeps the production change separate from the YouTube destination. The broadcast remains associated with the feed YouTube is receiving; the scene selection determines what OBS sends in that feed. It does not create a second live video or a new watch page. If viewers need to find a separate event, scene-switching alone will not give them that separate destination.
Prepare for the transition you actually want. A cut may be appropriate between two full-screen video sources, while a fade or other transition may suit a change from an announcement card to a video. OBS transition behaviour, rendering load and file playback can differ across computers and configurations. Test the selected transition with the actual files and output settings rather than assuming it will look identical under live conditions.
For a local news loop or small business channel, a scene can also make it easier to insert a short notice between longer videos. Keep the notice and next video ready in advance, then choose the intended scene. If you are still deciding whether OBS fits your production needs, this comparison of Streamlabs Talk Studio and OBS Studio gives broader context; it does not change the core distinction between a source change and a separate broadcast.
Use VLC Video for a playlist
If several files should play in order, OBS’s VLC Video source can use a playlist. This is different from setting one Media Source to loop: a single-file loop repeats that file, while a playlist can move through multiple entries and can be configured to loop the list. OBS notes that VLC must be installed for the VLC Video source to be available, and that 64-bit OBS requires 64-bit VLC. Consult the OBS VLC Video Source guide before building the workflow.
Prepare the playlist on the computer running OBS and confirm that each entry is reachable. A playlist that refers to files on another machine, a removed drive or a path that has changed may fail even if it worked when first created. Test the order, playback, audio and loop behaviour before making that source part of a live scene. If your aim is just to rotate a few videos continuously, the examples in how to run retro gaming footage on repeat may help you think through repeat playback, though your own source configuration still needs testing.
A playlist is convenient for ordered, local playback, but it does not remove the need to supervise the stream and media. Review the list when content changes; make sure that the files are the versions you intend to publish, and check for blank tails, unexpected black frames or audio that carries on after the picture changes. If content has licensing or rights requirements, check those separately. Playback tools do not establish permission to use a file.
If OBS does not offer the VLC source, check the VLC installation and whether its architecture matches OBS before troubleshooting the YouTube connection. Avoid changing stream keys or destination settings to solve a local playback problem. The encoder destination controls where the feed goes; the source controls what is in the feed.
A source change is not a new broadcast
A changed Media Source or scene changes the video content sent through the current encoder feed. Viewers ordinarily continue on the same YouTube live video. That is the right mental model for changing a bhajan, ambience loop, study track or programme segment while retaining the existing broadcast. It is not a way to publish another live event with its own title, schedule or watch page.
Google’s YouTube Live Streaming API documentation describes a different case: a channel has a 24/7 broadcast and creates a separate broadcast, then binds it to a stream. In the example, the original 24/7 broadcast remains live as the separate one is made live; the separate broadcast can later be completed without stopping the encoder feed. The documentation puts the key point this way: “However, you don't stop streaming video since the 24/7 broadcast continues.” Read the simultaneous broadcasts example in the YouTube Live Streaming API documentation for the resource-based workflow.
That is API documentation, not a promise that every YouTube Studio user can perform the operation with one click. If you need two distinct live videos, investigate the current official API workflow and its requirements, or arrange the broadcast operations deliberately. Do not try to create a second broadcast by switching scenes and assume YouTube will treat it as a separate event. Conversely, do not end the existing live video merely to change its picture if the existing watch page is the one you need to retain.
YouTube offers different encoder approaches, including software and standalone hardware, but the underlying distinction remains: the encoder sends a feed and the broadcast is the YouTube live object associated with it. A cloud service for prerecorded continuous streaming is another operational approach, not a source change inside a local OBS session. StreamNeo addresses the specific burden of keeping a prerecorded file channel running when you do not want to leave the computer that plays it switched on; it does not turn an OBS scene change into a separate YouTube broadcast.
| What you need | Typical route | What changes for viewers |
|---|---|---|
| Replace one video in the current live video | OBS Media Source | Content in the same feed and broadcast |
| Move to a prepared layout and video | Switch to an OBS scene | Content and layout in the same feed and broadcast |
| Play a sequence of local videos | OBS VLC Video playlist | Playlist content in the same feed and broadcast |
| Publish a second YouTube live video | Separate broadcast workflow, such as the documented API resource flow | A distinct broadcast, not merely a different source |
If the current broadcast is already live, do not treat these routes as interchangeable. Choose the row that matches whether you want a different picture in the same live video or a separate live destination.
Test the transition before relying on it
Test with the actual files and scenes before a night-long or unattended run. Check that the next file loads, that its sound is present at a sensible level, and that the transition behaves as you expect. Let a playlist run through the end of one item into the next, and test any loop setting. Confirm that a source does not reveal an unintended desktop, empty frame or other scene underneath it.
Then test the broadcast path, not just the local preview. YouTube’s Live Control Room shows whether YouTube is receiving the encoder feed. Keep it open during a planned change where practical and check that the feed continues to arrive. YouTube’s guidance distinguishes the stream settings and incoming encoder content; stopping content from the encoder ends the stream. Its encoder setup and streaming guidance is the right place to check current steps for your account and interface.
Do not infer from a successful preview that every viewer will see a perfectly uninterrupted picture. The OBS documentation establishes source and playlist capabilities, not a guarantee that every computer, file, network or configuration will switch without a visible pause. File decoding, computer load and the network path can all affect what reaches YouTube. If the change matters, test it at a time when you can observe the result and intervene.
For a 24/7 setup, make the recovery plan explicit. Know which scene or source should be active after a restart, where the files are stored, and how you will confirm the incoming feed. If the encoder drops, recovery is a separate problem from changing media; see steps for recovering a continuous stream after an encoder crash. If a local computer is carrying the stream, consider whether power, network and overnight supervision are adequate. For a cloud-based approach, how to start a YouTube 24/7 stream with a cloud service in India outlines that broader operating choice.
Also consider the archive separately from the live picture. YouTube says streams under 12 hours are automatically archived; its guidance does not make the same automatic-archive promise for a 24/7 stream. If you need a recording of a long-running feed, plan and verify recording or archive arrangements independently rather than assuming that the complete continuous stream will be available afterwards.

FAQ
Does changing an OBS video source keep the same YouTube live video?
A source change sends different content through the encoder feed; it does not create a separate YouTube broadcast. Keep the encoder sending to the existing destination if your aim is to change the picture in that live video. A gap-free transition is not guaranteed, so test your files and scene change first.
Can I publish a separate live video while the 24/7 broadcast stays live?
The YouTube Live Streaming API documentation describes simultaneous broadcasts by using separate broadcast resources associated with a stream. That is a different workflow from changing an OBS source, and the API example should not be read as a one-click Studio procedure. Check the current official documentation before relying on it.
Should I use Media Source or VLC Video?
Use Media Source for one local file, including when you want to repeat that file. Use VLC Video when you need a local playlist, and confirm VLC is installed in a version compatible with your OBS installation. In either case, test the playback and transition before using it in a continuous live setup.
Will YouTube automatically archive my 24/7 stream?
YouTube says streams shorter than 12 hours are automatically archived, but that statement does not promise an archive for a stream running continuously for 24 hours or longer. Check YouTube’s current help guidance and arrange separate recording if retaining the footage matters to you.
