A black screen between videos in an OBS YouTube Live playlist can come from the source stopping or hiding, another scene layer covering it, or a transition that needs checking in your actual setup. For multiple local files, start by confirming that you are using OBS’s VLC Video source, then inspect the playlist, visibility and scene order before testing consecutive files.
OBS documents VLC Video as the playlist-capable source, but its documentation does not guarantee gap-free playback across every file and configuration. Treat the checks below as a way to isolate the symptom, not as a universal checkbox fix.
Check the boundary where the black screen appears
First establish what viewers mean by “between videos”. A blank that appears only at the end of one file and lasts until the next begins is different from a source that stays black for the entire next file. A short interruption visible only to one viewer may also differ from a black frame in OBS’s own output. Those distinctions point to different parts of the path, so note the timing before changing settings.
Watch the OBS preview or programme output around the boundary. If it goes black there too, investigate the local source, its visibility and the scene layers. If OBS continues to show video while the YouTube viewer turns black or changes quality, note that difference separately. A comparison is a diagnostic step; it does not reveal or guarantee how YouTube will handle every rendition or network condition.
Write down which two files were playing, the time in each file when the blank appeared, and whether it cleared by itself. If the issue recurs at the same pair of files, test those files again in a short session. If it moves between boundaries, review the whole playlist and the active scene. Avoid replacing files or changing several properties at once: doing so makes it harder to tell which observation matters.
Also confirm that the scene you are inspecting is the one actually being sent to the stream. An OBS collection can contain multiple scenes and sources, and a preview of a different scene cannot establish what viewers are receiving. If a browser or a second device is available, compare the stream output with OBS during the same transition.
Confirm VLC and OBS architecture match
For a sequence of local videos, OBS documents VLC Video as the source that can play a list of items as a playlist. It is distinct from Media Source, which is documented for a selected media file and has its own end-of-playback options. In the scene that is actually live, open the Sources dock and confirm which source carries the videos. Do not assume that several Media Sources arranged in a scene behave like one playlist.
VLC must be installed for VLC Video to appear as an available source. The OBS Media Sources documentation also says that 64-bit OBS requires 64-bit VLC. If the source is missing, check the installed applications and their bitness before rebuilding the scene. OBS provides the Media Sources documentation with the source distinctions and dependency details; interface wording can vary with software versions.
Compare the documented options before deciding which source fits the job:
| Choice | Playlist handling | Dependency and trade-off | Appropriate use |
|---|---|---|---|
| Media Source | Selects a local media file; documentation does not present it as the multi-item playlist source. | Built into OBS, with file playback properties including an end-of-playback behaviour. | One file, or a scene designed around separate sources. |
| VLC Video | Plays a list of media items as a playlist. | Requires VLC; OBS says 64-bit OBS needs 64-bit VLC. Includes playlist, visibility and caching controls. | A local multi-file playlist. |
This comparison describes the documented source roles, not a guarantee that either source will behave identically with every codec or file. The formats listed in OBS’s documentation are not proof that every file encoded in a listed container will decode cleanly. Test the actual media on the computer and OBS setup you intend to use.
If the playlist is currently a series of individual sources, first decide whether you need a fixed sequence or independently controlled scene elements. VLC Video is the documented playlist route for multiple items; separately arranged sources may make sense for a different production design, but they add scene states and visibility to inspect. A related guide to looping a recorded stream with FFmpeg and a remote Linux server covers a different playback approach; it is useful context if you are weighing a local OBS arrangement against a server-based workflow, not a fix for an OBS transition.
Review playlist order and loop or shuffle settings
Open VLC Video properties and check that every intended file is present and ordered correctly. A missing or misplaced item can look like a playback failure if the next thing in the list is not what you expect. For a devotional channel, for example, verify that the closing bhajan in one set is followed by the intended opening item, rather than assuming the list retained its earlier order after edits.
For a predictable sequence, check that Shuffle Playlist is off. Loop Playlist controls whether the list starts again after the final item; it does not control how one file hands off to the next. The documented defaults are loop on and shuffle off, but verify the actual properties in your source rather than relying on remembered defaults or another scene’s settings. A loop setting answers what happens after the whole list, not whether each boundary is frame-perfect.
VLC Video also offers behaviour for when the source is not visible, including continuing, pausing or stopping playback, and it exposes network caching. OBS documents a 400 ms default for network caching. For files stored locally, do not increase caching on the assumption that it removes gaps between local files: the documentation does not make that claim. First find out whether the source remains visible and active through the blank.
If you use a source in more than one scene, check that its visibility behaviour and playback position fit that use. A source hidden when you switch scenes may continue, pause or stop according to its settings. That can change which item is playing when you return to the scene, but it does not by itself identify the cause of a black interval. Test the specific scene change and file boundary that viewers experience.
Check source visibility and scene order
Look at the Sources dock while the affected scene is active. OBS renders higher entries above lower entries, so a visible colour source, image, browser layer or other video source can cover the playlist below it. Temporarily hide possible covering layers one at a time in a test scene or test session and observe the boundary. Restore any layers that are part of the intended programme after the check.
Confirm the eye or visibility state of the playlist source itself. If it is hidden at the boundary, the scene may reveal a lower layer, or the empty scene background. That can appear as a black screen even though the next file is playing. Conversely, a visible playlist source may be obscured by something higher in the stack. OBS explains this stacking behaviour in its Sources Guide; it cannot say which source is covering yours without inspecting your scene.
Be careful not to transfer a Media Source setting to a VLC playlist. OBS documents “Show nothing when playback ends” for Media Source: when enabled, that single-file source hides at the end rather than holding its final frame. If it is the only video layer, its disappearance may reveal a blank background; if another layer is underneath, that layer may show. The documentation does not establish that setting as the remedy for a boundary between VLC playlist items. Confirm what your own source does before changing end-of-playback behaviour.
A simple test scene can help separate the playlist from the rest of the production. Put the playlist over a known background, with no decorative overlays, then observe a boundary. If the picture remains visible there but the normal programme scene turns black, return to the full scene and check stacking and visibility. If the minimal scene also blanks, focus on the source, files and playback test. This comparison narrows the area to inspect; it does not prove a single cause.
Test consecutive file boundaries
Do not judge the playlist only from a preview of the middle of a file. Start a brief test stream or recording that includes the end of one item and the beginning of the next, then watch the resulting output. OBS’s Quick Start Guide recommends testing for a few minutes rather than jumping straight into a first stream. For this particular symptom, include a real file boundary in that test; an uneventful middle section says little about the hand-off.
Use at least one pair that has previously shown the problem. Keep notes on the file names, source type, relevant playlist settings, scene and what OBS preview and YouTube viewer show. If the stream is intended to run unattended overnight, the test should include a boundary under the same playlist and scene conditions you plan to leave running. A successful brief check is useful evidence, not a promise that every later boundary will be identical.
If one pair consistently fails, test each file on its own in the target setup and then test that pair in a simplified scene. This can distinguish a file-specific playback issue from an interaction at the boundary or an overlay in the full scene. OBS advises limiting costly sources and using suitably sized media in its Performance Guide. Reduce avoidable scene complexity if playback stutters, but do not assume that lower resolution will eliminate every black frame.
For a 24/7 channel, repeated manual checks of every boundary can become part of the maintenance burden. When the specific pain is keeping a pre-recorded file on air without leaving your computer to run OBS, StreamNeo can remove the need to keep that computer on; it does not change YouTube’s rules or guarantee a particular transition. If you prefer to keep playback in OBS, make the local test and scene checks part of your own operating routine. The always-on prerecorded video service overview may help you consider that operational choice, while a comparison of playlist scheduling in Switchboard Live is relevant if scheduled blocks, rather than a local VLC playlist, are what you need.
What OBS documentation does not guarantee
OBS documents how VLC Video provides a playlist, what playlist controls are available, and which VLC dependency is required. It also documents how source stacking works, how Media Source can behave when a file ends, and general testing and performance guidance. None of those points is a stated guarantee of gap-free playback between every pair of local files.
Keep that distinction in view when reading forum advice or trying a setting suggested for a different setup. Loop and shuffle govern list repetition and order. Visibility options govern what happens when the source is not visible. Media Source’s end behaviour is not documented as a VLC playlist transition control. Network caching is exposed in the VLC source, but OBS does not say that changing it fixes local-file boundaries.
YouTube adds another layer after OBS sends the feed. OBS says YouTube transcodes streams, and its article on YouTube streaming discusses consistent keyframe intervals in the context of smoother changes between viewer quality options. That context can help when a viewer reports a quality change, but it does not make keyframe settings a remedy for a blank in the local OBS scene. Keep the question precise: does the source or OBS output go black, or is the difference only in what a viewer sees?
Documentation and interface labels can change between releases. Check the current OBS pages and your installed version when an option is missing or renamed. If a boundary still fails after confirming the source, dependency, list, visibility and scene stack, keep the test notes and investigate the affected files and local playback path rather than assuming a universal configuration exists.
A practical order for the next test
Work from the simplest, most observable checks towards broader changes. Confirm the live scene and source; confirm VLC Video and the matching VLC installation; inspect order, shuffle and loop; then check visibility and sources above the playlist. Test the pair of files in a simplified scene before changing output settings or rebuilding the whole stream.
If a test changes the symptom, record exactly what changed and repeat the boundary. If it does not, restore the original setting before trying the next diagnostic step. This keeps the comparison meaningful and avoids accumulating changes that make the stream harder to maintain. A test record is particularly useful when someone else operates the channel or when a stream needs to be checked after an OBS update.
For viewers, the most important distinction is whether the blank is in the source output or only in one playback experience. Capture what you observe during the same interval; do not describe a viewer quality shift as proof that the local playlist stopped. If the source itself blanks, continue with local file and scene checks. If OBS remains normal, investigate the viewer path separately and use current official guidance rather than altering unrelated playlist settings.

FAQ
Is VLC Video the right OBS source for multiple local videos?
OBS documents VLC Video as the source that can play a list of items as a playlist. It requires VLC to be installed, and the OBS documentation says 64-bit OBS requires 64-bit VLC. Confirm the source in the scene that is actually live.
Should I turn on “Show nothing when playback ends” to fix a playlist gap?
That is a documented Media Source option for what happens when an individual file ends. It is not documented as a fix for a gap between items in VLC Video. Check the actual source type and observe the boundary before changing it.
Does turning off shuffle prevent black screens?
Turning off Shuffle Playlist makes the order predictable; it does not guarantee a gap-free hand-off. Check the item order and then test the affected consecutive files in the actual scene and output.
Can YouTube keyframe settings fix a black screen between local files?
OBS’s YouTube guidance discusses keyframe intervals in relation to transitions between viewer quality options. It does not identify them as a fix for a local VLC playlist boundary. First determine whether OBS’s own output is black at the same moment.
