To change videos without ending a YouTube Live broadcast, keep the event and encoder session running, and change the media in OBS, which supplies the video to the encoder. For prerecorded content, OBS's VLC Video source can play a list of files; the YouTube event itself is not a native playlist editor for this workflow.
That keeps the live event active, but it does not guarantee a clean, seamless picture or sound at every change. Test the exact files, scene, OBS and VLC versions, machine, and 4K/60 output you intend to use before relying on the setup overnight.
Keep the YouTube event active
Think of the broadcast as two connected parts. YouTube Studio holds the live event and receives the encoder feed; OBS prepares that feed from your scenes and sources. A playlist change belongs in the production part. You do not need to end and recreate the event simply to move from one prerecorded clip to another.
In YouTube's encoder workflow, you select or create an event, provide the encoder with the server URL and stream key, check the incoming preview, and start the broadcast. YouTube's encoder instructions describe End Stream as the action used to finish the event. Leave that control alone when your goal is only to change the clip.
Before making any change, identify what is currently sending video. If OBS is the encoder, its active output should remain connected to the same event. Changing a source or scene in that live OBS session changes the content being sent; ending the event or stopping the encoder is a different operation. Confirm that you have selected the intended event and stream key first. A stream-key check can help prevent sending the feed to the wrong scheduled broadcast.
This distinction matters when a devotional channel moves from one bhajan recording to another, or a study channel replaces a long ambience file. The viewer may see a brief transition, a black frame, or a pause depending on what OBS and the media do. The operational aim is to keep the event live while you change the source, then verify what viewers actually receive.
Change media in the production layer
A YouTube event is the destination, not the place to organise the local files in an encoder-based prerecorded broadcast. OBS is the production layer: it contains the scene, the media source, and the controls for what the encoder sends. Put the replacement content there rather than looking for a YouTube Studio playlist control that changes the running encoder feed.
If you already have a scene with a playlist source, keep the encoder output running and use the controls available in your installed OBS and VLC versions to advance the list. If you are switching between prepared sources or scenes instead, make that switch in OBS while watching the preview and the live event's incoming feed. The exact interaction depends on your setup, so check the controls in your version rather than assuming one universal button sequence.
Preparing a second scene can make the change easier to reason about: one scene can hold the current content and another the next item. But a scene switch is still a production change, not a promise of uninterrupted audio or picture. Test it with the actual sources. For example, a static logo and ticker layered over video may be a separate source that needs to remain visible through a scene change; see this GStreamer overlay guide for the related production concern.
Keep the encoder's destination settings stable while you practise. Changing the YouTube event or reconnecting the encoder is not needed just to select a different file. If you do need to repair the stream connection, treat that as a separate recovery task; these steps after a power cut address a different interruption scenario.
Set up an OBS VLC Video playlist
OBS documents a VLC Video source that can play multiple video and audio files as a playlist. Its Media Sources documentation explains the source and its playlist settings. The source is available when VLC is installed, according to OBS's Sources Guide. Check your installed versions because menus and behaviour can vary.
In the scene used for prerecorded content, add or select a VLC Video source, then choose the files and arrange them in the order you want. Use files you have permission to stream and that you have already checked for picture and sound. Choose whether the source should loop or shuffle according to the programme: a sequence of lessons or news items may need a fixed order, while an ambience station may want a loop. Do not assume shuffle and loop mean the same thing: one affects selection order, the other whether playback returns to the list after reaching its end.
Consider what should happen when the source is hidden. OBS's source settings include visibility-related playback behaviour; the result depends on the options you choose. If a playlist is meant to keep playing while its scene is hidden, verify that behaviour rather than assuming the source pauses or continues. This can affect which clip is next when the scene returns.
A sensible preparation step is to name the source clearly, such as “Main playlist” or “Next programme”, and keep a separate note of the file order. For a channel run by more than one person, that avoids changing the wrong source at a busy moment. The video library organisation guide offers useful principles for making a folder and naming scheme easier to maintain.
Advance or replace playlist content
For a planned change, the lowest-risk approach is usually to prepare the list before going live. Confirm the order, play each file far enough to check that it opens, and listen for the expected audio. Then use the playlist's available controls to move to the next item while OBS continues sending its output. OBS documents playlist playback, but individual control labels and placement may differ by version.
If you need to replace an item during a live session, first decide whether the replacement can wait. A live edit introduces more uncertainty than using a list already tested. If it cannot wait, add or select the replacement through the source's playlist controls, check the preview, and verify the event is still receiving the feed. Avoid changing several settings at once; that makes it harder to identify why a source behaved unexpectedly.
There are a few practical choices to settle in advance:
| Choice | What it changes | What to check before broadcast |
|---|---|---|
| Fixed order or shuffle | Whether items follow your planned sequence or vary | Confirm that the next item is appropriate for the programme |
| Loop or stop at the end | Whether playback returns to the list or reaches its end | Check what viewers will see and hear after the last file |
| Continue while hidden or pause | Whether playback progresses when the source is not visible | Test which item appears when the scene returns |
| One playlist or prepared scenes | Whether you advance within a source or switch production layouts | Check picture, audio, overlays, and source visibility |
Do not treat a playlist's ability to advance as evidence that the transition will be imperceptible. A file may take time to open, have a different frame rate or audio layout, or behave differently when decoded on your machine. A playlist is a way to organise playback; it does not certify that each hand-off is clean.
If this is a repeating programme, document the change process in a short run sheet: current item, next item, what to verify in preview, and who is watching the event. That is more useful than relying on memory during a long broadcast. It also makes it easier to distinguish a content change from a connection problem.
Avoid the End Stream control
End Stream is for finishing the broadcast, not for moving between playlist items. YouTube's live stream settings help describes controls for managing the live stream. Keep the event open while OBS supplies the next media item if the intention is to continue the same live programme.
Similarly, stopping OBS's output or disconnecting its encoder feed is not the same as changing the content in a source. It can interrupt what YouTube receives, and the result of reconnecting may depend on the event and encoder state. If you are unsure, practise on a controlled test event rather than experimenting on a broadcast your viewers are using.
A useful operator habit is to put the End Stream control outside the sequence of actions used to change media. Keep the playlist or scene controls in the production workflow and reserve the YouTube event controls for event management. If a second person is monitoring chat or the Live Control Room, agree who can end the event and who can operate the source.
When the programme is genuinely finished, use YouTube's normal end-of-stream process and stop sending encoder content as instructed. A clip ending, a playlist reaching its last item, and a decision to end the live event are separate conditions. Decide what should happen at the playlist's end before the broadcast, especially if nobody will be present to intervene.
Test scene and source transitions at 4K/60
A 4K/60 broadcast puts demands on the whole path: media decoding, OBS composition, encoding, the connection, and YouTube's ingest. A source that plays smoothly on its own may behave differently when OBS is encoding and sending the full scene. Test at the resolution and frame rate you plan to use, with the actual media and overlays, rather than treating a lower-quality rehearsal as proof.
YouTube's encoder settings guidance lists 4K/2160p at 60 fps and gives bitrate guidance by codec. In the retrieved table, AV1/H.265 has a 10 Mbps minimum and 40 Mbps maximum, while H.264 has a recommended bitrate of 35 Mbps. These are not one codec-independent target; check the current table and match the figures to the encoder codec you use. YouTube also transcodes streams for different viewer formats, so your outgoing setting is not a guarantee that every viewer sees the same resolution.
That guidance also notes that 4K/2160 streams do not have the low-latency option available; they are optimised for quality at normal latency. If near-real-time interaction matters more than 4K resolution, reconsider the production trade-off rather than assuming a playlist setting can change latency. For background on the distinction, see whether latency mode changes bitrate requirements. A separate 1440p bitrate walkthrough can help when comparing a lower-resolution production plan.
During a test, check the outgoing OBS preview and the YouTube Live Control Room preview. Observe the change itself: does the next file open, is there a blank image, does audio cut or overlap, and does the event report stream-health warnings? Then check viewer-side playback as well. A clean local preview does not establish that the complete path is healthy.
YouTube recommends testing before going live and monitoring stream health. Its tips also recommend setting up an encoder at least two hours before an event and starting it at least 15 minutes before the scheduled time. Treat these as preparation recommendations, not guarantees that an event will be trouble-free. Leave room to correct a file or source setting before relying on the broadcast.
Monitor the event during changes
Have one person make the source change and, if practical, another watch the event preview and stream-health indicators. If you are working alone, keep the Live Control Room visible and avoid walking away immediately after the switch. Confirm that the picture has changed to the intended file, audio is present, and the event remains live.
If the event preview freezes or the stream-health status changes, stop making additional playlist edits until you know whether the issue is the source or the connection. Check OBS's output state, the selected scene and source, and whether the file is still playing. If the encoder has stopped sending, that is a different problem from an ordinary playlist advance; use the relevant recovery process and avoid repeatedly toggling event controls without knowing their effect.
Keep a small log during the first real run: time of change, old and new item, what the preview showed, and any warning. This is not a claim that every event needs a formal operations team. It is a practical way to learn whether a particular file or transition needs a different approach on your machine. Once the sequence has been tested, keep the successful settings and file order documented.
If you operate an always-on channel from a home computer, consider who will notice a problem overnight and what action they are authorised to take. The goal is not to pretend that software removes every failure mode; it is to make the expected change routine and make an unexpected interruption visible.

FAQ
Can I change the video without ending the YouTube Live event?
Yes. For an encoder-based broadcast, change the media in the production software feeding the encoder while leaving the YouTube event and encoder session active. Check the event preview after the change; keeping the event active does not guarantee a seamless transition.
Does YouTube Studio have a playlist editor for this change?
The documented workflow here uses an OBS VLC Video source playlist, not a native YouTube Studio editor for changing prerecorded clips in an encoder feed. YouTube receives the output from the encoder. Configure and test the playlist in OBS.
Will the transition be seamless at 4K/60?
Not necessarily. The result depends on the files, source and scene behaviour, software versions, machine, and outgoing stream. Test the actual transition at the intended resolution and frame rate, and monitor both the OBS preview and YouTube's event health.
What should I do if the next file does not appear?
Check that the intended OBS scene and VLC Video source are selected, the file is available to the source, and playback has advanced as expected. Verify the incoming preview and stream health before making further changes. Use End Stream only when you mean to finish the broadcast, not as a playlist troubleshooting step.
