For an ordered, repeating playlist of local videos, use OBS Studio’s VLC Video source: install VLC, add the files in sequence, leave Shuffle Playlist off and enable Loop Playlist. YouTube’s live event is a separate setup; create or schedule it in YouTube Studio, then connect OBS with the event’s stream URL and key.
Those steps configure playback and a broadcast, but they do not prove the stream will continue unattended. Test the playlist, encoder, YouTube start and stop controls, and your actual internet connection before relying on the channel overnight.
Prepare the videos and check the computer
Put the files you intend to play in a local folder and confirm that they open and play through to the end. Check the soundtrack as well as the picture: a file that opens successfully can still have missing audio, an unexpected blank section or a different loudness from the next item. A short, deliberate review of each file is more useful than assuming that a familiar export is correct.
OBS documents support for common media formats through its media sources, including MP4, MOV, MKV, AVI, WebM, TS, MP3 and WAV. The VLC Video source uses VLC libraries for broader media support. If a particular file fails, first test it in VLC itself and check the format and encoding; do not assume that changing a YouTube setting will repair a local playback problem. See the OBS media source documentation for supported source behaviour and formats.
For a 4K/60 broadcast, distinguish the resolution and frame rate of your output from the properties of the source files. A 4K/60 output setting does not turn lower-resolution footage into genuine 4K, nor does it make a 30fps file contain new frames. It asks OBS to encode an output at that setting, which can add work for the computer. If your files are mixed, decide whether that output is needed for the channel rather than selecting it just because one file has a 4K label.
Check that the computer can decode the files and encode the intended stream while OBS is running. A 4K/60 encode can be demanding, and performance depends on the computer, encoder choice, media and scene. Play the most demanding clip in your planned setup and watch OBS for rendering or encoding warnings. A successful test with a static title card is not evidence that a high-motion concert recording or animated background will behave the same way.
Keep the media available where OBS expects it. A playlist that points to a removable drive can fail if the drive is unplugged, changes its assigned location or goes to sleep. An external SSD can be useful if the library is too large for internal storage, but it is not required by this workflow. Use stable local paths and avoid moving or renaming files after assembling the playlist.
Install VLC and add the VLC Video source
Install VLC before building the OBS scene. OBS’s VLC Video source depends on VLC being present; if it is missing from the source list, installation and matching system architecture are the first things to check. In particular, OBS documents that a 64-bit OBS installation needs 64-bit VLC. Restart OBS after installing VLC if the source still does not appear.
Create or open the scene that will carry the playlist. In the Sources panel, add a VLC Video source and give it a name that describes its job, such as “Main playlist”. If you have several scenes, a clear name makes it easier to select the right source later and reduces the chance of accidentally changing a different source.
In the source properties, add the local files to the playlist. The exact controls can vary slightly with the OBS version, but the relevant source is VLC Video, not a YouTube playlist URL pasted into a browser source. This workflow plays files from your computer through OBS; it is not the same as sending a list of YouTube video links to a live event.
Set the source’s visibility and playback behaviour deliberately. A source can be hidden when you change scenes. Depending on its settings, playback may stop, pause or continue while hidden. If the stream uses only one scene, this is less likely to surprise you, but still test what happens when the source is hidden and shown again. For a scene-based programme, decide whether a temporary title or break scene should pause the playlist or let it continue underneath.
Keep the first setup simple: one scene, one VLC Video source and a few test files. Confirm that the picture fits the canvas, audio is present and the source behaves as expected before adding overlays or scene transitions. Once that baseline works, add any titles or graphics and repeat the playback test.
Arrange files in the intended order
The VLC Video source playlist is the playback sequence. Add files in the order you want viewers to see them, then inspect the list rather than trusting the order in which files were selected. Alphabetical file names can be a useful aid: names such as 01-opening.mp4, 02-bhajan.mp4 and 03-closing.mp4 make the intended order visible, though the playlist itself remains the setting to verify.
Check the transitions between items. VLC Video moves through the playlist, but a clean result depends on the files: the end of one item and beginning of the next may contain silence, black frames, a slate or a change in loudness. Watch at least one full transition in OBS. If the channel is meant to feel continuous, trim or replace files that introduce an unintended gap rather than expecting the live service to smooth it over.
Think through the programme as viewers will encounter it. A devotional channel might place an opening card before a morning sequence and a closing card before the playlist repeats. A study stream might alternate longer focus sessions and short breaks. OBS will follow the order you provide; it does not understand your programme plan or rearrange items based on time of day.
If the playlist is long, retain a separate written copy of the intended sequence. That gives you a simple reference when a file is replaced or a new item is added. After any edit, revisit the OBS source properties and verify both the visible order and the number of entries. Do not rely on an old test as evidence that a changed playlist is still correct.
An ordered list also makes troubleshooting easier. If playback jumps to the wrong item, identify the current and next files in the source list, then check the shuffle setting and scene visibility behaviour. For a related OBS issue, see how to fix a media source that restarts instead of continuing a playlist. That problem is distinct from YouTube event scheduling: it concerns how the local source behaves.
Disable shuffle and enable playlist looping
In the VLC Video source properties, leave Shuffle Playlist disabled for predictable sequencing. With shuffle enabled, the sequence is not the order you carefully arranged. That may suit a station that wants random selection, but it is a poor fit when the programme has an opening, planned segments or a specific ending.
Turn on Loop Playlist if you want the entire list to repeat when it reaches the end. Looping the playlist is different from repeating one file: check that the source contains all intended entries and observe the transition from the final item back to the first. If you do not want the programme to repeat, leave looping off and decide what viewers should see after the last file finishes.
The names of these controls matter because they belong to the media source. Loop Playlist governs local playback in OBS. It does not schedule a YouTube event, reconnect a failed encoder or make a broadcast start at a chosen time. Those are separate operations, configured elsewhere and tested separately.
Test a short playlist before using the full library. Include at least two files so you can see the sequence change, and make the final test item short enough that you can observe the end-to-start loop without waiting through a long programme. Then test with the actual files and scene arrangement. A small test catches a wrong order or disabled loop early; it does not replace a full-duration reliability test.
If you use more than one scene, test the source when it is hidden and then made visible again. A source that restarts on a scene change may replay the current item from the beginning instead of continuing. If that is not the behaviour you want, adjust the source’s visibility behaviour and retest scene changes. A playlist that loops correctly in a single scene can still act differently in a multi-scene layout.
Create or schedule the YouTube live event
Open YouTube Studio and create a live stream or schedule the event for the intended time. If live streaming has not previously been enabled on the channel, YouTube says first-time activation may take up to 24 hours. Check the channel’s current live eligibility and activation status well before the broadcast; a configured OBS scene cannot make the feature available sooner. YouTube’s walkthrough is in Create a YouTube live stream with an encoder.
In Live Control Room, choose the event details and visibility appropriate for your test or broadcast. A private or unlisted test can help you verify the signal without presenting it as a public programme, but use the current controls shown in your account. Scheduling the event creates or arranges the YouTube-side event. It does not load the local playlist into OBS, and loading a playlist in OBS does not create or schedule the event.
Review the stream settings for auto-start and auto-stop. YouTube makes these controls available in its live stream settings when enabled. They affect how the live event responds to encoder start and stop; they do not mean that OBS will automatically begin playing at a scheduled hour. Verify the controls for the specific event and account rather than assuming that a setting from a previous broadcast carries over. The official live stream settings guidance explains the event-side controls.
Keep the stream key private. Anyone with access to it may be able to send a signal to your stream, so do not share it in a public screenshot, a support post or a file that is broadly accessible. If you think it has been exposed, use YouTube Studio’s current controls to reset it and update OBS with the new key.
Connect OBS and set the 4K/60 output
In YouTube Studio, copy the stream URL and stream key for the event. In OBS, open the streaming settings, choose the appropriate service configuration, and enter the supplied destination and key in the corresponding fields. Keep the key out of public notes and screen recordings. Confirm that you are connecting to the intended event, especially if you have a scheduled programme as well as a separate test stream.
Set the OBS output and video settings only after checking the computer’s available encoder and your upload path. YouTube’s published English encoder guidance gives a 4K/2160p at 60fps range of 14–50 Mbps for H.264 and 10–35 Mbps for AV1 or H.265. These are YouTube’s guidance figures, not a promise that your ISP, Wi-Fi or computer can sustain them. Check the current guidance shown for your account and selected codec in YouTube’s encoder settings.
| 4K/2160p at 60fps codec | YouTube-published bitrate range | What to verify |
|---|---|---|
| H.264 | 14–50 Mbps | The OBS encoder and upload connection can sustain the selected output |
| AV1 or H.265 | 10–35 Mbps | Your available encoder supports the codec and the connection remains stable |
Do not choose AV1 or H.265 solely because the published range is lower. The computer must support the selected encoding path, and your viewers and workflow need to be served by the output you configure. Conversely, choosing H.264 because it is familiar does not remove the need to test. The appropriate setting is the one that your equipment and sustained connection can actually maintain.
YouTube recommends constant bitrate (CBR) and a two-second keyframe interval, and says not to exceed four seconds. Set those values in the encoder settings where applicable, then verify the stream health feedback in Live Control Room. Use a wired connection where practical and run a speed test on the same connection at the time you expect to broadcast. A single speed-test result is only a snapshot, so leave room for ordinary household or business network use and interruptions.
A 4K stream uses normal latency on YouTube; YouTube says low- and ultra-low-latency modes are not available for 4K. If viewers need near-real-time interaction, reconsider whether 4K is essential or whether a lower resolution better suits the programme. See YouTube’s explanation of live streaming latency. Resolution, bitrate and latency are related choices, but the playlist order itself does not determine any of them.
Test start, loop and stop behaviour
Test the whole chain before you depend on it. Start with an unlisted or private test event, confirm OBS is sending the expected scene, and check YouTube’s preview and stream health. Watch both picture and sound. Use a representative clip with motion and audio, not only a static image, because encoding load and audio faults may show up only during real playback.
Test the playback sequence explicitly: start the source, observe it move from one file to the next, then confirm that the last item returns to the first when Loop Playlist is enabled. If you use scene changes, hide and show the source as part of the test. Record what happened and adjust one setting at a time, so you can tell whether a fix changed playback, the stream output or the YouTube event response.
Then test event controls separately. With the relevant YouTube auto-start setting enabled, check whether starting the encoder produces the expected event state. With auto-stop enabled, check what happens when you stop the encoder. The purpose is to establish the behaviour for your channel and event before relying on it, not to assume that the playlist’s end or loop setting will start or stop the YouTube broadcast.
Do not use an overnight broadcast as your first end-to-end test. Check the setup for a meaningful period, including transitions and the conditions under which you expect the channel to run. Test again after changing the stream key, output settings, playlist files, OBS version or scene behaviour. A setup can be correct today and still fail after a file is moved or a power or network interruption occurs.
For a local OBS setup, the computer has to remain powered, the media accessible, OBS running and the connection available. You can use monitoring and alerts to notice some failures, but they cannot prevent every interruption; this guide to alerts for a 24/7 stream covers the practical distinction between detecting a problem and preventing it. If leaving the computer on is the part you cannot reliably manage, StreamNeo removes that specific burden by turning an uploaded file into a YouTube live stream without keeping your own computer running; it does not change YouTube’s event controls or remove the need to check the channel and content.
For a broader comparison of local and hosted approaches, see YouTube 24/7 live streaming with a playlist: OBS or cloud service. The trade-off is operational: OBS gives you local control, while a hosted workflow can avoid leaving your own computer on. Neither approach means you should skip testing the event, audio, playback and expected start/stop behaviour.

FAQ
Does an OBS playlist schedule a YouTube Live event?
No. VLC Video handles playback of the local files in OBS; YouTube Studio handles creating or scheduling the live event. Configure both parts and test their interaction. Enabling YouTube auto-start does not make the OBS playlist start at a scheduled time.
Why is VLC Video missing from OBS?
The VLC Video source requires VLC to be installed. OBS also documents that 64-bit OBS needs 64-bit VLC, so check that the installed versions match and restart OBS after installation. If the source is still missing, confirm which OBS build you are running and consult the OBS media source documentation.
Will Loop Playlist keep a YouTube stream live overnight?
Loop Playlist repeats the local playlist; it does not guarantee that the encoder, computer, power or internet connection will remain available. Test the full setup and monitor it if you plan to leave it running. YouTube auto-stop and auto-start are separate event controls and should also be tested for your channel.
Can I use low latency at 4K/60?
YouTube’s encoder guidance says 4K streams use normal latency rather than low or ultra-low latency. If near-real-time interaction matters more than 4K detail, consider testing a lower-resolution output and compare it against your audience’s needs. Confirm the current account guidance before broadcasting.
