For a repeating set of local videos in OBS, add a VLC Video Source, put the clips in the order you want and enable Loop Playlist. That repeats the list, but OBS does not promise that playback will change files without a frame or audio gap.
If a pause or flash at a boundary matters, combine the clips into one continuous file and test it as an OBS Media Source with Loop enabled. This is a practical alternative, not a guarantee of seamless playback: check both the clip joins and the end-to-start loop with the exact files and setup you plan to use.
Choose a playlist or one continuous file
A VLC playlist is convenient when you want several files to play in order, or need to replace or rearrange clips individually. OBS's VLC Video Source supports a playlist and can repeat it. A single combined file is easier to treat as one playback item, but changing one segment means preparing the combined file again.
The distinction matters because there are two kinds of boundary to inspect. A playlist has joins between one file and the next, then a loop boundary from the final file back to the first. A combined file removes the playlist's file changes, but its edit points and its own end-to-start loop still need testing.
| Approach | What OBS repeats | Useful when | What to verify |
|---|---|---|---|
| VLC Video Source playlist | The ordered list of files | You expect to add, remove or reorder clips | Every file-to-file join and the list's end-to-start boundary |
| Media Source with one combined file | A single local media file | The sequence is settled and you want fewer source changes | Edit points inside the file and its loop boundary |
Neither approach should be described as a certified gapless playback mode. The OBS media sources guide documents source options, including playlist and loop controls, rather than promising frame-accurate or audio-sample-accurate joins. Start with the playlist if flexibility is the priority; try a combined file if you hear or see a boundary problem.
If the stream is part of a longer-running station, source continuity is only one part of the workflow. You may also want to plan how the rest of the channel stays available during a local connection problem; the guide to keeping a 24/7 playlist stream running through an Indian internet outage covers that separate issue.
Install VLC with the same architecture as OBS
OBS relies on VLC for its VLC Video Source. Install VLC before setting up the source, and match its architecture to OBS: a 64-bit OBS installation needs 64-bit VLC. If the source is missing from the add-source menu, check that VLC is installed and that the architectures match before troubleshooting the playlist itself.
You can check OBS's architecture in its About information or by looking at the version you installed. Use the official VLC download route rather than an unrelated download site, and avoid installing a different build merely because its name looks similar. After installing VLC, fully close and reopen OBS so it can detect the available media component.
Keep the clips together in a folder with clear filenames before adding them. Names such as 01-opening, 02-main and 03-closing make the intended order easier to review, though the order you add them to the playlist is what matters. If you move or rename files later, OBS may no longer find them at their saved locations.
VLC Video Source is a good fit for a local OBS workflow where the computer and source files remain available. If you are comparing a local setup with a cloud-run loop for a channel that should continue when your computer is off, make that a separate operational decision; this overview of cloud services for a 24/7 lo-fi radio stream is relevant to that broader question, not a fix for a playlist boundary.
Add a VLC Video Source and order the clips
Open the scene that should display the videos. In the Sources box, select the add button, choose VLC Video Source, and give the source a name that makes its purpose clear, such as “Main playlist”. The exact appearance of the dialog can vary by OBS version, but use the source properties to add files to its playlist.
Add the clips in the sequence you intend viewers to see. Review the list from top to bottom rather than assuming alphabetical or folder order will match your plan. If your OBS properties include controls to add, remove or reorder playlist entries, use those controls and check the resulting order before closing the dialog.
Leave Shuffle Playlist off when the channel needs a fixed sequence. Shuffle is useful for variety, but it changes the expected order and makes it harder to reproduce a specific boundary during testing. OBS lists shuffle as off by default, but saved properties or an existing scene may differ, so inspect the actual source rather than relying on defaults.
Size and position the source in the scene as you normally would. If it should fill the canvas, check for empty margins or cropping in the preview. Those framing issues are separate from a gap at a file boundary: a source can be correctly placed and still pause between clips, or play continuously while being framed incorrectly.
For scheduled blocks that change through the day rather than a single fixed playlist, a playlist may not be enough. The guide on scheduling rotating video blocks on a 24/7 YouTube stream addresses that different problem. Here, keep the source simple enough that you can identify which item is playing and inspect each join.
Enable Loop Playlist
In the VLC Video Source properties, turn on Loop Playlist if you want playback to return to the beginning after the last item. OBS's documented default is on, but check the box in the source you are actually using: a project can contain older settings, and you should not infer the behaviour from a newly created source.
Looping the list and shuffling it are separate settings. For a fixed sequence that repeats, Loop Playlist should be enabled and Shuffle Playlist should be disabled. Save or close the properties, then let the playlist reach its last item during a local test so you can confirm that it begins again as intended.
This setting answers “what happens after the last playlist item?” It does not establish what happens at each transition between files, nor does it promise an uninterrupted transition from the final item to the first. Treat the settings as playback instructions and verify the actual output rather than reading a loop checkbox as a continuity guarantee.
Do not confuse a source boundary with a scene transition. OBS scene transitions apply when you switch from one scene to another. Choosing Cut rather than Fade can affect that scene change, but it does not document or control the VLC source's internal move from one playlist file to another. The OBS Studio overview describes scene transitions; the playlist's media behaviour is a separate matter.
Try one combined file as an alternative
If testing shows a black flash, a pause or an audio break at a playlist join, prepare a single file containing the clips in their intended order. Then add it as a Media Source and enable Loop in that source's properties. OBS documents Media Source looping a local file after playback completes, which is a practical way to remove the need for OBS to move between separate playlist entries.
This changes the problem; it does not certify the result. The combined file still contains edit points where one clip meets the next, and it has an end-to-start loop boundary. Whether those points appear continuous depends on the files and playback setup. Check that audio does not click or drop out and that the picture does not show a black frame or pause where the clips meet.
Make the combined file only after you have settled the sequence and checked that the source clips are usable together. Keep the original files and export a separate combined version so you can revise it without losing your inputs. If you need to change one segment, re-export and test the new file rather than assuming the earlier result still applies.
Avoid adding a transition simply to hide an unexplained pause. A dissolve or fade alters the picture and may not address an audio break; it can also change the editorial look of devotional, study or ambience content. First identify whether the issue occurs at a file join, at the overall loop, or in the YouTube delivery path. The right adjustment depends on which boundary is actually failing.
A single file may also be less convenient if you frequently rotate new material. In that case, keep the playlist workflow and accept that each join needs checking, or maintain an updated combined file when the sequence changes. The trade-off is flexibility versus a simpler playback sequence, not a promise that one format always performs better.
Test the boundaries, not just the middle
A video that looks fine halfway through a clip has not yet proved that its joins work. Test every playlist boundary and the final-to-first loop point. Watch the OBS preview and listen on headphones or speakers that make a short audio interruption noticeable. Pay attention to a brief black frame, held image, visible jump, silence or click.
Test with the actual files and the scene you will use. Codec, file properties, OBS version, operating system and playback configuration can affect a particular result, and the OBS documentation does not settle every combination. Do not conclude that a file pair will behave the same on a different computer simply because it worked elsewhere.
If you find a problem, change one thing at a time. Try the combined-file method, then replay the same boundary. If that boundary appears clean locally, test the end-to-start loop as well. Keep a note of which version and source properties you tested; this makes it easier to tell whether a later edit or setting change introduced a new issue.
Only after local playback looks right should you check the YouTube path. YouTube's encoder setup uses a server URL and stream key entered in OBS's streaming settings. Follow YouTube's encoder setup instructions, start the encoder and inspect the Live Control Room preview before making the stream public or relying on it for a long session.
YouTube recommends testing before a broadcast and checking stream health and audio/video quality. Use its current encoder settings and bitrate guidance for your chosen resolution and codec. Encoder bitrate and keyframe settings affect the stream sent to YouTube; they are separate from whether OBS changes cleanly from one local media file to another.
A local boundary and a viewer-side interruption are also different things. YouTube describes latency as the delay between capture/encoding and viewer playback, and lower latency can involve more buffering. So a clean OBS preview does not guarantee every viewer sees an identical result, and buffering seen by one viewer does not by itself prove the playlist has a gap. Check both the local source and the platform preview, then monitor stream health during the test.
Keep the rest of the live workflow in view
This guide concerns playback inside OBS, not whether a channel is ready to run unattended for a full day. If you are streaming from a home connection, the computer, OBS process and upload path remain part of the chain. For a long-running setup, consider how you will notice an interruption and who can respond if the stream stops. The article on remote monitoring for a pre-recorded YouTube Live stream covers that operational side.
A continuous source can reduce the number of file changes you need to inspect, but it does not remove the need to test your encoder connection or check YouTube's preview. Likewise, a successful test on a desktop monitor is not the same as observing the YouTube stream as a viewer. Keep these checks separate: source playback, stream health and viewer delivery each answer a different question.
If managing a local computer through the night is the specific pain, StreamNeo removes that particular need by turning an uploaded video into a YouTube live stream that can continue with your computer switched off. It does not change the fact that your media should be prepared and reviewed before streaming, and the service is YouTube-only.

FAQ
How do I loop multiple videos in OBS?
Add a VLC Video Source, put the videos in the playlist in the desired order and enable Loop Playlist. Keep Shuffle Playlist off if you need the same sequence on each pass. Test the joins and the point where the final clip returns to the first.
Why is there a black flash between videos?
A black flash can appear at a file boundary, but OBS's documentation does not diagnose the cause for a particular clip or computer. Reproduce the boundary locally and try a combined file as a Media Source with Loop enabled. Check the resulting edit point and the file's loop boundary rather than assuming the workaround guarantees a clean result.
Will a Cut scene transition remove the gap?
There is no documented basis for expecting it to. Cut applies to switching scenes, while the VLC playlist changes media files inside a source. Inspect the playlist boundary or test a combined file instead.
Will viewers see a completely seamless stream?
You cannot infer that from Loop Playlist or Media Source Loop alone, and you should not promise it. Test locally, inspect YouTube's preview and monitor stream health; viewer-side buffering and latency are distinct from the local media boundary.
