A black screen when a video ends usually means the source or scene feeding your encoder has stopped showing that video; it does not, by itself, show that YouTube is at fault. If you use OBS, first identify whether the video is an OBS Media Source or a VLC Video source, then check the matching loop setting and compare OBS’s preview with the YouTube live output.
The right fix depends on what supplies the picture. OBS documents Loop for a Media Source and Loop Playlist for VLC Video, but other encoders can behave differently. Work through the source and output checks below before changing stream settings or replacing equipment.
Identify the software and source
Start by locating the software that sends the picture to YouTube. YouTube describes encoder-based streaming as sending content from streaming software or a hardware encoder to the live stream. If you have OBS open, use its scene and Sources panels to find the item that contains the video. If you use another encoder, find its corresponding media, file, or playlist source instead; do not assume OBS’s labels or options exist there.
In OBS, select the source and open its properties. The source type matters: an OBS Media Source is generally the direct file source, while VLC Video uses VLC’s media playback and can work with a playlist. The controls are not interchangeable. OBS documents the Media Source’s Loop setting as repeating the file after playback completes, and VLC Video’s Loop Playlist as restarting when the source runs out of media files. OBS notes that VLC must be installed for the VLC Video source to be available. See the OBS Media Sources guide for the source options and their descriptions.
Also establish what you mean by “loop”. YouTube’s viewer-side repeat control applies to watching a video or playlist on YouTube; it does not change the file being sent into an encoder-based live broadcast. The repeat behavior has to be set where the live picture is produced. YouTube explains its viewer repeat control in YouTube Help.
If the setup is a playlist of short clips rather than one long file, the end transition may be a playlist or scene issue rather than a single-file loop setting. The distinction is useful in other workflows too; this guide to looping short clips without black frames covers the related challenge of moving between multiple clips.
Find out whether the source or the live feed ends
Before changing settings, observe where the black screen first appears. Watch the encoder preview around the end of the file. If it turns black there, the issue is already present before YouTube receives the stream: investigate the source, scene, or transition. If the encoder preview continues to show the intended picture while the YouTube watch page turns black, compare the live output and stream health before changing the source loop.
Note what happens to the audio as well. Audio continuing while the picture disappears can help narrow the symptom to video visibility or a visual transition, though it does not prove a particular cause. If both picture and sound stop, check whether the encoder has stopped sending content or whether a playlist has run out. YouTube says that ending a stream involves stopping content from the encoder, so a source stopping is not the same thing as a viewer pressing a repeat control.
Make the observation repeatable. Write down the source name, the scene currently active, and whether the preview and watch page change at the same moment. If possible, monitor the preview before the file ends and immediately after it should restart. A simple note such as “OBS preview black, audio continues; live page matches” is more useful than repeatedly toggling unrelated settings.
A 24/7 channel may use one file, a rotation of several files, or a scene that changes between sources. The test differs for each. A long devotional recording configured as one Media Source should be checked at that source’s end; a local-news rotation should be checked at the boundary between playlist items or scenes. For a broader look at prerecorded channel formats, see how 24/7 prerecorded live streams work on YouTube.
Enable Loop for an OBS Media Source
For an OBS Media Source, select the source that contains the file, open Properties, and enable Loop. OBS documents this setting to replay the file once playback completes. Save or close the properties, then test the end again in the preview. Confirm you have changed the source actually used by the live scene; a similarly named source in another scene may not be the one viewers see.
Do not treat Loop as a universal remedy. It is the documented setting for an OBS Media Source, not a guarantee that every black screen originates there or that the same control exists in every encoder. If the correct source already has Loop enabled, keep investigating rather than repeatedly toggling it. If you use a different encoder, consult that software’s documentation for its own file-repeat or playlist-repeat setting.
If your OBS source is VLC Video, check Loop Playlist rather than expecting the Media Source’s Loop property to apply. OBS describes that option as restarting the source when it runs out of media files. It is relevant to a VLC Video source and its playlist, not a generic instruction for all source types. A single-file workflow and a playlist workflow may therefore call for different properties.
After enabling the appropriate setting, verify the result in preview over an end-of-file transition. A source may still disappear because of another property or because the scene changes at the same time. If that happens, preserve the observation and move to the visibility and transition checks rather than assuming the setting failed.
Check playlist and scene transitions
When a loop property is on but the screen still goes black, inspect what OBS does when playback ends and what the scene shows behind the source. OBS documents Show nothing when playback ends as hiding the source automatically when the video finishes. If enabled, the source can reveal another layer or an empty scene when it reaches the end. That is a plausible cause to check, not proof that it is responsible in your setup.
Also review Restart playback when source becomes active and how source visibility is controlled. A source that is hidden and then made active may restart, while a scene transition or visibility change can alter what the audience sees. Compare the relevant source properties with the scene timeline or any automation that changes scenes. Change one setting at a time and test again so you know which change altered the result.
For a playlist, check the boundary between the final item and the next one. Confirm that the playlist contains the expected files and that the software is configured to repeat the playlist if that is the intended behavior. A pause or blank interval could come from how items are sequenced, but do not assume a particular duration or cause without observing it. Test the same transition with a short sample playlist before relying on a long unattended run.
Scene changes can create a similar symptom even when a file repeats correctly. For example, a video source may loop in one scene while a scheduled transition switches to a scene with no visible media. Check scene names, visibility icons, and any hotkeys or automation around the time the video ends. If the channel rotates several programmes, keeping playlist rotations in sync across channels is a related operational concern, but it does not replace checking the local transition that produces this black frame.
Compare encoder preview with YouTube output
Once the local preview behaves as expected, compare it with the YouTube live watch page. YouTube recommends testing a stream and checking the encoder preview in Live Control Room before starting. Its live streaming tips also advise monitoring audio and video quality. Use those checks to establish whether the picture is correct before YouTube receives it and whether the audience sees the same result.
Allow for the fact that the watch page may not show a change at exactly the same instant as the encoder preview. Focus on whether the live output eventually reflects the same image and whether a black screen persists across the transition. Keep the stream private or unlisted during a controlled test if that suits your workflow, and avoid changing multiple settings between the preview and live comparison.
If OBS preview is correct but the live page is black, note the time and check the Live Control Room status and stream health. Confirm you are looking at the current broadcast and the intended live page, rather than an old or ended stream. YouTube’s Live Control Room guidance covers encoder setup and monitoring. A correct preview makes a source-end setting less likely to be the only issue, but it does not identify a YouTube fault by itself.
For a channel that must continue while your computer is off, the operational problem is keeping the same tested file and channel running without relying on a local machine through the night. StreamNeo turns an uploaded video into a YouTube live stream, so the specific task of keeping a file running is not tied to leaving your own computer on. It does not change the need to test the source, confirm the live output, and check that the content is suitable for your channel.
Review stream health if preview is correct
If the encoder preview stays correct but viewers see black, inspect the stream health indicators and any warnings in Live Control Room. Check whether the encoder is still connected and sending video, whether the watch page is showing the active stream, and whether the symptom affects the entire picture or only a particular scene. This evidence helps separate a source transition from an interruption in the outgoing feed; it is not a diagnosis on its own.
Check the encoder’s own status around the transition. If it reports a disconnect or stops sending, address that separately from the video’s Loop property. YouTube says the encoder is what sends the content to the live stream, so a source that repeats locally and an encoder that successfully transmits are distinct parts of the workflow. If the stream health message points to connection capacity, review your available upload bandwidth and the encoder’s chosen bitrate rather than attributing it to the file ending.
YouTube’s streaming tips recommend leaving upload-bandwidth headroom, with its page recommending 20 per cent. That recommendation concerns connection capacity, not a specific cause of a black frame at the end of a file. Do not raise or lower bitrate as a first response when the preview itself turns black; correct the local source or scene behavior first. Conversely, if preview is stable and stream health shows a transmission problem, the source loop setting may be unrelated.
If the evidence remains unclear, capture a short test recording or note the exact transition time, source type, and messages shown in the control room. Then review the relevant encoder and YouTube documentation, or ask for help with those details. Avoid claiming YouTube has a platform defect without evidence, and do not use viewer-side repeat as a substitute for configuring the outgoing source.
Retest the end-of-file transition
Use a controlled retest after each relevant change. Let the file play through its end in the encoder preview and verify that it restarts or hands off to the next item as intended. Then compare the YouTube output and confirm that audio and picture continue. YouTube recommends testing before a stream and monitoring quality; a transition that works once in preview is a useful check, but not a promise that every future session will behave identically.
For a long programme, you do not necessarily need to wait through the entire file for every adjustment. Use a copy or short test clip that reaches an end quickly, with the same source type and relevant properties, then validate the actual file before depending on it. Do not let the test change obscure the real configuration: record which scene, source, and loop property were involved, and restore intended settings after testing.
Before an overnight or unattended broadcast, verify the live page as well as the local preview. Confirm the channel is sending the intended source, the end transition behaves correctly, and the stream remains active after the file restarts or the playlist advances. A small checklist can include the source type, the relevant loop option, the visibility behavior, and whether the live output matches preview. That checklist is more reliable than assuming yesterday’s settings still apply after a scene or file change.
The same discipline helps when you are diagnosing other output symptoms. If audio is present but the picture is absent throughout the stream rather than only at the end, use a different branch of troubleshooting, such as this guide to a YouTube radio livestream with audio but no video. A black frame confined to the file boundary calls for source and transition checks first; a persistent missing picture calls for a wider review of the outgoing video.

FAQ
Does YouTube’s Repeat button make my live stream loop?
No. YouTube’s repeat control is for a viewer watching a video or playlist; it does not configure the media source that an encoder sends to a live broadcast. Set repeat behavior in the software or source producing the stream.
Which OBS setting should I use for a single video file?
For an OBS Media Source, enable Loop in that source’s properties. If the source is VLC Video, check Loop Playlist instead; the control depends on the source type.
What if OBS preview is correct but the YouTube page is black?
Check that you are viewing the active stream, then review Live Control Room and encoder status around the transition. A correct preview narrows the investigation to the outgoing stream or its display, but does not prove YouTube is at fault.
Does this fix apply to every encoder?
No. The steps above use settings documented for OBS Media Source and VLC Video. For another encoder, identify its source type and consult its own documentation for file or playlist repeat behavior, then test the preview against the live output.
