For separate video files, OBS’s documented playlist option is a VLC Video source. It requires VLC installed with an architecture that matches OBS; OBS documents looping, shuffle, visibility behaviour and network caching, but not a gapless-playback or crossfade toggle.
If black gaps persist, joining the clips into one file and playing it through a Media Source is a practical workaround to try, not a verified or guaranteed OBS fix. First establish whether the gap is present in the broadcast, then check the source setup and its available controls before changing your files.
Confirm the black gap is in the broadcast
A black interval in the OBS preview is not automatically proof that viewers receive the same interval. Likewise, seeing a black frame on YouTube does not identify which part of the chain caused it. Check a recording or the stream output itself and compare it with the local preview around the moment one clip should end and the next should begin.
For a controlled test, make a short recording from the same OBS scene and source configuration. Watch the file across a playlist boundary. If the recording shows the same black interval as the preview, focus on the media source, files and scene visibility. If the preview looks continuous but the recording or live output does not, investigate the output path separately rather than assuming a VLC playlist setting is responsible.
Keep the test simple: use two clips with an obvious visual change, and note which one is meant to play first. Avoid changing multiple properties at once. A useful record is the source type, the ordered filenames, whether the source is visible, and whether the black appears in preview, recording or the YouTube output. That gives you a repeatable comparison instead of relying on a brief glimpse during a long-running channel.
This distinction matters for a devotional rotation, a study stream or a local information loop. A short black frame between files may be a source-boundary issue; a longer black scene could also mean the wrong scene is active or a source is hidden. OBS’s documentation describes how its media sources work, not a YouTube playlist control for removing OBS file transitions. The viewer-experience checklist is useful for thinking about what a viewer actually sees, but the first job here is to locate where the black interval appears.
Install matching-architecture VLC and add a VLC Video source
OBS documents VLC Video as the source for a playlist of media files. The OBS Media Sources guide says VLC must be installed for this source and that its architecture must match OBS. In practical terms, if your OBS installation is 64-bit, install 64-bit VLC; installing VLC alone is not enough if the architectures do not match.
Add the source from the Sources dock in the scene where the videos should appear. Choose VLC Video, then open its properties. The OBS Sources Guide covers adding sources and notes that VLC provides playlist functionality when available. Labels and layout can vary between OBS versions, so check the current interface rather than expecting every button to appear in the same place as an older guide.
If VLC Video is missing or does not behave as expected, check the dependency before diagnosing clip timing. Confirm that VLC is installed, close and reopen OBS after installation, and make sure both programs use the matching architecture. If OBS still cannot offer the source, do not try to compensate by adjusting playlist options that are not present. Resolve the source availability first.
This setup is different from adding each file as a separate Media Source. VLC Video is intended to hold multiple files as a playlist in one source, while Media Source is aimed at an individual media file. If you already use the OBS VLC Video folder-loop workflow, the playlist concept will be familiar; for this problem, pay particular attention to the sequence and boundaries between the individual files.
Load and order the video playlist
In the VLC Video source properties, add the files you want and arrange them in the intended order. Check the list itself, not just the first item: a mistaken order can look like a transition fault when the actual issue is that the source is playing an unexpected clip, a blank asset or a file with black frames at its start or end.
For a small test, use two known files and temporarily remove the rest. Choose files that play correctly on their own and have no intentional black tail or opening slate. If the interval disappears with those two files, add the remaining items back gradually. This does not prove the source will behave identically under every condition, but it narrows the search without changing the entire channel setup at once.
File names can help prevent mistakes. Prefixing them with an order marker such as 01, 02 or 03 makes the intended sequence easier to inspect, though the playlist’s displayed order remains what matters. For a bhajan channel, for example, check whether the next track’s file begins with a title card that is itself black before assuming OBS inserted a gap. For an ambience station, inspect whether the source footage fades to black at the end by design.
A playlist source is useful when you want to manage several separate clips and keep loop or shuffle behaviour in one place. It also means each file boundary is a point worth testing. Avoid treating a sequence that looks right in the properties list as proof that the rendered output is continuous: observe an actual transition in a recording or the live output.
Check the documented playback controls
The VLC Video properties include controls for looping the playlist, shuffling it, and responding to source visibility. Review each in relation to the symptom, but do not assume that any of them removes a gap between two files. Their documented purposes concern list repetition, order and visibility behaviour, not a specific gapless-playback promise.
| Control or choice | What it is for | What it does not establish |
|---|---|---|
| Loop Playlist | Restart the list when it reaches the end | That transitions between items are gapless |
| Shuffle Playlist | Change the order in which items play | That a black boundary will disappear |
| Visibility Behaviour | Set how playback responds when the source is not visible | That hiding and showing a source improves file transitions |
| Network caching (ms) | A VLC source property for network media | That increasing it fixes boundaries between local files |
The OBS documentation lists a default of 400 ms for Network caching (ms). That is a documented property, not a recommended setting for eliminating gaps between local playlist files. The guide does not say that raising it removes those gaps. If your playlist uses local files, changing the network cache on that basis is not an evidence-led fix; if you use network media, follow the guidance for that media and test the result rather than assuming it addresses a local-file boundary.
Visibility behaviour deserves attention if your scene switches, sources are hidden, or the source becomes visible only at particular points. Check that the source remains visible during the transition you are diagnosing. If you use Media Source instead, OBS documents settings such as Show nothing when playback ends and Close file when inactive. Those affect file end and inactive-source behaviour; closing and reloading a file when it becomes active can introduce a delay, but these are not documented inter-item gap-removal settings.
The important distinction is between a control that OBS exposes and a control that OBS documents for this particular goal. The cited documentation does not identify a gapless-playback or crossfade toggle for VLC Video playlists. Do not follow advice that presents a named switch as an official fix unless you can verify it in current OBS documentation and in your own version. You can also compare the playlist approach with running different YouTube playlist schedules on one OBS PC, which concerns scheduling rather than a guarantee about transition timing.
Test transitions and isolate the gap
Once the source and list are correct, make one change at a time and test the same boundary again. Keep a copy of the original properties or note the settings before you adjust anything. If you change visibility behaviour, for example, do not simultaneously alter the file order and cache value; otherwise you will not know which change affected the result.
Check the files outside OBS as well. Play the last portion of the first file and the opening portion of the next, looking for black frames, a fade, a title card, a decoding delay or an audio-only tail. A visible pause can be part of the content itself. If you have access to an editor, inspect the ends and starts on a timeline. This checks the media before attributing the interval to OBS.
Then test the transition in the actual scene. A source may be present in the Sources dock but obscured by another source, or the scene may switch while the playlist changes. Temporarily simplify the scene to the VLC Video source and any essential overlays. If the simplified scene behaves differently, restore elements one at a time to identify a visibility or layering interaction.
If local preview and recording differ, capture a fresh short recording and compare the same boundary. If the YouTube output differs from both, treat that as a separate output investigation: confirm the right scene and source are live, and check whether the interval repeats at the same media boundary. The OBS references here do not establish that YouTube introduces, or can remove, a gap caused by the playlist. For a 24/7 stream, record what you observed and when before making a change that could affect the running broadcast.
There is no need to make a long-running channel your first test. A short isolated sequence can show whether a proposed change affects the boundary. Afterward, test the full intended playlist in the scene and on the output you rely on before leaving it unattended. This is particularly important if a source’s visibility changes as part of a schedule or scene rotation.
Consider joining the clips into one file
If separate-file transitions remain a problem and you can prepare the sequence in an editor, joining the clips into one continuous file is a reasonable workaround to try. OBS documents Media Source for individual media files and VLC Video for playlists. The suggestion to join items before playback follows from that distinction; it is an inference, not an OBS-certified cure or a tested guarantee that black frames will disappear.
A single prepared file can simplify the playback sequence because OBS is opening one media file rather than moving through separate playlist entries. It also changes how you manage the channel. Replacing one section may mean rendering the sequence again, and you need enough local storage for the prepared file. Check the start and end of every join in the editor, then play the full render before using it for a live channel.
OBS documents a range of media formats for Media Source, including MP4, TS, MOV, FLV, MKV, AVI, GIF and WebM. Choose a format that your editor can export and that OBS can play in your setup, then test the rendered file inside the actual scene. Do not assume that a format listed in the documentation guarantees correct playback on every computer or with every file encoding. If the prepared file still has black frames, inspect the render and source media rather than expecting a different OBS source to remove content that is already black.
| Approach | Useful when | Trade-off to consider |
|---|---|---|
| VLC Video playlist | You want to retain several separately managed files | Requires VLC with matching architecture; transitions need testing |
| Media Source with a prepared file | You can prepare the sequence as one file | Updating one clip can require editing and exporting the sequence again |
If you would rather keep files separate, stay with VLC Video and accept that OBS does not document a gapless setting for this purpose. If a continuous presentation is essential, test the joined-file approach on a short sequence first, then inspect the full output before relying on it. StreamNeo addresses a different operational problem: it removes the need to keep your own computer running for a file-based 24/7 YouTube broadcast, so a local machine is not the thing that has to stay on overnight.

FAQ
Is there a gapless-playback or crossfade toggle in OBS VLC Video?
The cited OBS documentation describes playlist controls such as looping, shuffle, visibility behaviour and caching, but does not document a gapless-playback or crossfade toggle. Check the current documentation and your installed version before relying on advice that names such a setting.
Does increasing Network caching remove black gaps between local files?
OBS lists Network caching (ms) as a VLC source property and gives a default of 400 ms. The documentation does not say that increasing it removes gaps between local files, so treat it as a network-media property rather than a proven local-playlist fix.
Is joining clips into one file a guaranteed fix?
No. It is a practical workaround to test, inferred from OBS’s distinction between a playlist source and a single-file Media Source. Inspect the joined file and test it in your scene and output before relying on it.
Why do I see black in the preview but not in the YouTube stream?
A difference between preview and output means you should diagnose the output path separately rather than assuming the playlist boundary is the cause. Compare a recording and the stream at the same point, and check scene visibility and source layering before changing the media.
