A black screen between videos in a 24/7 OBS stream does not identify its own cause. First establish whether your videos come from a Media Source, a VLC playlist, a browser or network source, or separate scenes, then observe exactly where the blank appears.
A short interval at a clip boundary can be a playback or visibility event, while a persistent blank may point to source configuration, rendering, or delivery. Work through the boundary in OBS before changing YouTube settings or rebuilding the stream.
Identify the source and scene setup
Start in the OBS Sources panel rather than with the symptom. Select the item that should show the video and note its source type. The troubleshooting path is different for a local Media Source, a VLC Video source, a browser or network source, and several scenes containing one video each.
A Media Source normally points to one local file. Its properties can control whether that file loops, whether anything remains visible after it ends, whether playback restarts when the source becomes active, and whether the file is closed while inactive. A VLC Video source can hold a playlist and has its own playlist and visibility controls. A browser or network source depends on the page or stream it loads, so a blank interval may occur inside that source rather than at a local file boundary.
Separate scenes create another possibility. For example, Scene A may contain the first video and Scene B the second. In that arrangement, the black area may appear during a scene transition, or because the next scene has no visible source at the moment it becomes active. It is not useful to apply VLC settings to a scene-based setup.
Write down the arrangement before changing it. Record the scene name, source type, file or playlist location, and whether the source is visible in the current scene. Also note whether the media is stored locally or reached over a network. The same black preview can have different implications depending on those details.
If your channel is built around a long local loop, the guidance on how big a loop file should be can help you review the file arrangement separately from the OBS playback fault. If you use many short clips, keep the individual filenames and order available while testing.
Observe when the black screen appears
Do not begin by assuming that every black interval is a playback fault. Watch one complete cycle and record the timing. Does the blank appear only between two clips, after the final item, when you change scenes, or after the source has been hidden and shown again?
Note what happens to the audio. If audio continues while the video area is black, the media may still be playing while the visible output, source state, or rendering path changes. If both audio and video stop, the source may have ended, paused, failed to advance, or lost access to the next item. These observations narrow the next check, but they do not prove a cause on their own.
Also record whether the last frame remains on screen or disappears immediately. A held last frame and a fully empty source are different behaviours. Check whether the interval affects every boundary or only particular files. If only one item causes the problem, inspect that file and its location before changing the whole playlist.
Use a simple observation sheet for one test cycle:
| Observation | What to record | Why it matters |
|---|---|---|
| Boundary | Between which two files or scenes | Shows whether the event is repeatable |
| Audio | Continues, pauses, or stops | Separates visible output from playback clues |
| Last frame | Holds or vanishes | Helps distinguish end display from an empty source |
| Source state | Visible, hidden, paused, stopped, or restarted | Connects the symptom to source behaviour |
| Scope | One item, every item, or the final item | Helps separate a file problem from a setup problem |
| Location | OBS preview, recording, or YouTube playback | Shows where the blank first appears |
For a 24/7 channel, perform this test during a planned observation period rather than repeatedly interrupting a public broadcast. A short local recording can reveal a boundary that is easy to miss in the live preview. If you record the test, include the OBS preview and enough of the Sources panel to show which scene and source were active.
Check Media Source playback behaviour
If the source is a local Media Source, open its properties and compare each setting with the behaviour you want. OBS documents these controls on its Media Sources page, including Loop, Show nothing when playback ends, Restart playback when source becomes active, and Close file when inactive.
Loop controls what happens after the file reaches its end. If you expect one file to run continuously, check that looping is enabled. If the file is intended to stop and hand control to another scene or source, looping may prevent the transition you expect. Do not enable it simply because a black frame appeared until you know whether the source is meant to repeat.
Show nothing when playback ends controls the display after the media completes. When enabled, the source can become invisible at the end rather than holding its final image. That may be correct for a scene that should reveal another source, but it can look like a black screen if no replacement is visible. If it is disabled, the final frame may remain, which can hide the fact that playback has ended.
Restart playback when source becomes active matters when the source is hidden and shown again, or when a scene containing it becomes current. With it enabled, activating the source can start it from the beginning. With it disabled, the source may resume or retain its existing playback position, depending on the rest of the setup. Test the same hide-and-show sequence that occurs in your stream rather than clicking the option in isolation.
Close file when inactive affects what happens when the source is hidden or off the current scene. OBS notes that showing the source again can involve a short period while the file reloads. That makes this setting particularly relevant when the black interval follows a scene change rather than a natural clip boundary. If you need the source ready immediately when it becomes visible, compare the behaviour with this option changed, one setting at a time.
Make one change, save the properties, and run the same test again. Changing Loop, Show nothing when playback ends, Restart playback when source becomes active, and Close file when inactive together removes the evidence of which setting mattered. Keep a note of the original values so you can restore them.
Check VLC Video playlists and dependencies
If the source is VLC Video, inspect the playlist itself and the VLC-specific properties. OBS describes VLC Video as a source that can play a playlist, with controls including Loop Playlist, Shuffle Playlist, and Visibility Behaviour. The same OBS documentation says that VLC must be installed for this source type and that a 64-bit OBS installation requires 64-bit VLC.
Loop Playlist controls what happens when the list reaches its end. This is different from asking whether each item advances correctly to the next item. A blank after the final file may relate to the end-of-playlist behaviour, whereas a blank between ordinary items requires you to examine the files, playlist order, and visibility behaviour.
Shuffle Playlist changes the order of items. Turn it off while diagnosing so that the same boundary can be reproduced. Once the setup is understood, you can decide whether random order is appropriate for the channel. A changing order makes it harder to identify whether one particular file is involved.
Visibility Behaviour determines what playback does when the VLC source is not visible. Depending on the chosen behaviour, playback may continue, pause, or stop while the source is hidden. This matters when you use multiple scenes or temporarily switch to a holding scene. A source that stops while hidden may need to restart when visible, while one that continues may have moved beyond the expected position by the time it returns.
Check that every playlist entry still points to an accessible file. A file that was renamed, moved, disconnected, or stored on an unavailable network location may fail even though the playlist entry remains. Test each item outside the live sequence where practical, then run the playlist with Shuffle Playlist off.
The documented controls do not promise perfectly gapless decoding at every file boundary. Do not treat a short transition interval as proof that VLC is incorrectly configured, and do not promise that one setting removes every gap. First determine whether the interval is consistent, whether the next item starts, and whether the same files behave differently when played individually.
Separate scene transitions from source playback
If each video has its own scene, inspect the transition between scenes. A scene can be active while its intended source is hidden, unloaded, not yet ready, or positioned outside the canvas. Check both the outgoing and incoming scenes in the preview before testing them live.
Review the selected transition and its duration. A fade or cut can expose a blank area if the incoming scene has no visible media at the start of the transition. A longer transition can make a brief source-loading interval more noticeable, but changing the transition does not repair a source that is failing to load. Test with a simple cut as a diagnostic comparison, not as a guaranteed fix.
Check source visibility using the eye controls in both scenes. Confirm that the video source is not hidden, that another full-screen item is not covering it, and that the source has not been moved or cropped out of the canvas. If a browser or network source is involved, open its properties and verify that the page or media address is still the intended one.
For automated setups, OBS developer documentation lists source lifecycle signals such as media_started, media_ended, media_play, media_restart, media_stopped, and media_next in its source reference documentation. These signals can help someone maintaining a script compare the time of the blank with a media ending or advancing event. They are evidence about timing, not a diagnosis by themselves.
An event that coincides with the blank suggests that playback or source state deserves attention. No matching playback event may shift the investigation towards scene visibility, transition timing, rendering, or the source itself. If you do not use scripts, you can still make the same comparison manually by watching the preview and noting the active scene and source state.
Test the stream inside OBS
After checking the configuration, test in layers. First play the file or playlist while watching the OBS preview. Then make a local recording that includes at least one complete boundary. A local recording is useful because it shows what OBS rendered before YouTube received the stream.
If the recording contains the black interval, the issue is already present in OBS or in the source it is rendering. Return to the source type, media properties, scene visibility, and transition timing. If the OBS recording is clean but the public stream is black, keep the OBS configuration unchanged and compare the live output in the next stage.
Repeat the test with one known local file. For a VLC playlist, temporarily reduce the playlist to a small set of known files. For separate scenes, use two scenes with clearly visible test clips or colour cards. This removes unnecessary variables without changing the production files permanently.
When a source has been hidden, show it again and observe whether the blank happens only on reactivation. Then restart OBS and repeat the same test if the symptom has occurred after the application was left open for a long period. Do not use an old issue report as a current diagnosis: for example, OBS issue #3192 records a particular report from July 2020 involving OBS 25.0.8 on Windows 10. It is historical context, not evidence that the same cause applies to a current installation.
If the first checks do not resolve the problem, collect the OBS version, operating system, exact source type, relevant source properties, media location, and whether audio continues. Note whether the last frame holds, whether all playlist files are affected, whether the interval occurs at every boundary, and whether it appears in a recording. An OBS log covering the incident and a short recording of the preview can make the timing clearer.
For a channel where the computer must remain available all night, also review the practical choices in how to keep a YouTube live stream running from a spare PC. That does not diagnose this OBS symptom, but it helps you separate a local operating arrangement from the content and scene configuration you are testing.
Compare OBS with YouTube preview and stream health
Once the OBS recording is clear, check what YouTube receives. Open the live control room preview and compare the same boundary. YouTube’s official live streaming troubleshooting guidance is the right place to check current delivery and encoder information rather than relying on a third-party checklist.
If the black screen appears in the OBS preview and the YouTube preview, the delivery platform is unlikely to be the first place to investigate. If OBS records clean video but YouTube shows a blank interval, compare the timing, stream status, encoder connection, and any warnings shown in YouTube Studio. A difference between the two views means the evidence has moved beyond local source playback, but it still does not identify one particular cause.
Watch the stream health indicators during a repeatable test rather than making a judgement from a single viewer window. A viewer can experience a temporary playback buffer that is not present in the incoming broadcast. Conversely, a clean local preview does not prove that the encoded stream is clean. Keep the test short and controlled, with a known boundary that you can identify in both recordings.
Do not repeatedly stop and restart a public 24/7 stream while experimenting. If the channel has a schedule viewers rely on, use the quietest practical test period and record the change. The article on setting up a 24/7 stream schedule viewers can rely on covers the operational side of planned changes, including why a troubleshooting test should be treated as a scheduled interruption rather than an invisible maintenance task.
If the stream is intended to be a devotional, study, ambience, or local information channel, document the exact media order and the time of the test. That record makes it easier to tell whether a later black interval matches the same file boundary, scene, or source reactivation. It also prevents you from changing several parts of a stable channel based on one unexplained observation.
For readers who decide that the recurring burden is keeping a local playback machine running rather than producing the videos, StreamNeo removes that particular computer-side task by letting you upload a prepared video, provide the YouTube stream key, and let the broadcast run with automatic monitoring and restart. It remains a YouTube-only route, so it does not replace diagnosing an OBS setup when OBS is the tool you have chosen.

FAQ
Why does OBS go black only between two videos?
The timing alone does not identify the cause. Check whether the source is a Media Source, VLC playlist, browser or network source, or a pair of scenes, then note whether audio continues and whether the last frame remains visible. The relevant investigation may involve end-of-file behaviour, playlist advancement, source visibility, or a scene transition.
Should I enable Loop in OBS?
Enable Loop only when the source is meant to replay the same local file. For a Media Source, also check what Show nothing when playback ends and Restart playback when source becomes active are meant to do in your scene arrangement. For a VLC playlist, inspect Loop Playlist instead, because it governs the list rather than a single Media Source file.
Why is my VLC playlist black when I switch scenes?
Check Visibility Behaviour and confirm that VLC is installed with the architecture required by your OBS installation. A source may pause, stop, or continue while hidden, and the next visible state may therefore differ from what you expect. Test with Shuffle Playlist disabled and compare the same scene change repeatedly.
How can I tell whether YouTube is causing the blank screen?
Make a local OBS recording that includes the boundary, then compare it with YouTube’s live preview and stream health information. If the recording is already black, investigate the OBS source or scene. If the recording is clean but YouTube is not, check the live delivery indicators and current official YouTube guidance before changing the media setup.
