A black screen after a yoga video loops can come from the source or scene, the encoder output, or the path from your encoder to YouTube. Test the file through its ending first, then compare what OBS shows with YouTube’s incoming preview and the viewer-facing stream; the title alone does not identify the cause.
If you use OBS with a prerecorded file, check whether the actual source is a Media Source or a VLC Video playlist, and inspect its loop and playback-end settings. If your setup does not use OBS or a prerecorded video, the same source-first method still applies: find where the picture disappears before changing settings at random.
Find the scene and source carrying the yoga video
In OBS, identify the scene that is live and the source in that scene that supplies the yoga picture. A scene can contain several sources, such as a video, a logo, text, or a background. The picture may also be nested in a group or another scene. The key is to identify the source that actually plays the moving video, rather than changing a similarly named source that is not on air.
Check the source list while the live scene is selected. An eye icon indicates whether a source is visible; a source can also be covered by another item higher in the list. If the image is already missing in OBS before you reach the end of the file, this is not yet evidence of a loop-boundary problem. Check whether the right scene is active, the video source is visible, and another source is not covering it.
For one video file, OBS’s Media Source is the relevant source type. For a playlist, the source may instead be VLC Video. Those are different controls, so first confirm which one you have. OBS describes the Media Source options in its media sources reference. A VLC source also has a separate VLC Video source guide explaining its playlist behaviour.
If your setup is not OBS, look for the equivalent point in the software that feeds the live stream: the playlist item, playback window, or scene layer that carries the file. Do not assume that YouTube’s viewer-side replay controls can repeat a file sent as a live broadcast. In that setup, the encoder or playback software must continue providing picture.
Test playback through the end of the file
Before changing the live configuration, play the same file locally from beginning to end. Watch the final moments, the exact point at which playback completes, and the first moments after it should repeat. A file that ends on a black frame, freezes before its last frame, or contains a deliberate fade to black can look like a software failure when the issue is in the content itself.
Run the test in the same player or source type you use for the broadcast if practical. A file playing correctly in a desktop media player does not prove that OBS can decode and loop it in the same way. Conversely, if it goes black at the same point in a local player, OBS and YouTube may simply be showing the source’s own ending. Keep the distinction clear: note whether the picture disappears before completion, exactly at completion, or only after a repeat begins.
If the file is part of a set, test each item and the transition between them. A playlist may contain a still image, a damaged or unsupported item, or a file with a different frame size or encoding. If the black screen follows one specific item, inspect that item and the playlist order before treating the issue as a general connection fault. Record the filenames and what you observed; that is more useful than repeatedly changing unrelated settings.
Make this a controlled test. Use a short test broadcast or a private/unlisted test where appropriate, rather than waiting overnight for the failure to recur. YouTube recommends testing before an event and checking the incoming preview before going live; its live streaming tips are a useful baseline. Avoid making a change and several other changes at once: if the symptom changes, you want to know which adjustment mattered.
Check the loop control for the source type
For a single local file in OBS, open the Media Source properties and inspect Loop. OBS documents that this control makes the file play again once playback completes. It is not the same as looping the YouTube watch page, and it applies to that source rather than every video in the scene. If it is off, the source may finish and stop instead of starting over.
For a playlist delivered by OBS’s VLC Video source, inspect Loop Playlist instead. OBS notes that VLC must be installed for this source type to be available. Do not look for a Media Source option and assume it controls a VLC playlist; match the setting to the source actually carrying the video. If the source type or installed component is uncertain, confirm that first rather than rebuilding the scene.
After checking the relevant option, test the boundary again in OBS. Look for whether the last frame transitions to the start, whether the source pauses, and whether another layer becomes visible. A loop setting can address a file that simply stops at completion, but it cannot repair a black frame embedded at the end of the video, an unsupported media item, a hidden source, or a separate encoder or delivery problem.
If you are using a command-line workflow instead of OBS, the loop behaviour belongs to the playback or encoding command, not to YouTube. The FFmpeg settings for prerecorded YouTube video may help you understand the separate roles of the file input and live output. Apply the documentation for the command you actually run; do not copy a setting meant for a different pipeline without testing it.
Review playback-end and visibility behaviour
OBS has a Show nothing when playback ends setting for Media Source. OBS documents that this hides the source when its file finishes. If the source reaches its end and disappears, that behaviour is worth checking alongside Loop. It is a diagnostic clue, not proof that it is the only cause, and changing it does not guarantee a black-screen fix.
Also check how the source is activated and how scenes are switched. A source may be set to restart when it becomes active, or to stop when it is not visible, depending on its settings and how your scenes are arranged. If you switch scenes around the time the file ends, the video might stop or restart as a consequence of scene behaviour. Check that your live scene remains selected and that the source remains visible over the loop boundary.
Use one change at a time. If you adjust a visibility setting, observe the source through the ending before you alter the loop control or encoder settings. A simple observation table can keep the diagnosis straight:
| What you observe | Where to look next |
|---|---|
| Black image appears in OBS before the file ends | Source visibility, scene order, media playback, and the file itself |
| OBS goes black at the file boundary | Source loop control, playback-end behaviour, and playlist contents |
| OBS remains clear but local recording goes black | OBS output path, encoder settings, and recording configuration |
| OBS and local recording look normal, but YouTube preview is black | Stream output, encoder errors, and the outbound connection |
| YouTube preview looks normal but viewers report a black picture | Viewer-facing delivery and the affected playback device or watch page |
These observations narrow the next check; they do not prove a root cause by themselves. A viewer report can also be affected by the viewer’s device or connection, so compare with the same watch page on another device or network before concluding that every viewer receives a black image.
Compare OBS preview with a local recording
When the next loop boundary occurs, check OBS’s preview first. If it turns black, the loss happens before YouTube receives the video: focus on the source, scene, playback-end setting, or file. If preview remains normal, make a local recording during a controlled test that includes the boundary. The recording gives you a second view of OBS’s output that you can review without relying on a live viewer’s memory.
If OBS preview looks correct but the local recording is black at the same point, the issue may be in the output or recording path rather than the visible source preview. Check recording and encoder settings, and test a short sample. If both OBS preview and recording are healthy, preserve that evidence before moving on. It does not establish that YouTube is receiving the same picture, but it makes a source-only explanation less likely.
Write down the time at which the boundary occurs, whether the local recording has the same gap, and which scene and source were active. If you need help from someone who maintains the setup, those details are more actionable than saying only that the stream went black. If you also see stream interruptions, distinguish those from a picture-only failure; reconnecting RTMP stream checks address a different symptom and may help you separate connection drops from a continuous stream with missing video.
Keep audio observations separate from picture observations. If audio continues while the video is black, that is useful evidence that the failure may be limited to the video source or video output. If both disappear, note whether the broadcast itself disconnected or whether the player stayed open without picture and sound. Neither pattern alone settles the cause, but each helps direct the next test.
Check Live Control Room preview and stream health
Once the OBS preview and local recording are accounted for, compare them with YouTube’s Live Control Room. For a planned test, wait for YouTube’s incoming preview before starting the broadcast. The official encoder setup guidance describes waiting for the preview to appear in Live Control Room. During the test, watch the incoming preview across the file boundary and note whether it matches OBS.
If OBS and the local recording remain normal while YouTube’s incoming preview turns black, the problem is farther along the output path: inspect encoder status, stream health and the outbound connection. Check for warnings or errors in Live Control Room and in the software sending the stream. YouTube’s stream troubleshooting guidance advises checking the encoder’s output, errors, CPU load and local archive as part of diagnosing a stream problem.
Then compare the incoming preview with the viewer-facing watch page. If the preview is good but the watch page is not, note the difference, the time, and the playback device used. Avoid using your own browser view as the only test: it can have a local playback issue that other viewers do not share. If a second device is available, check the same broadcast there, but do not treat one successful playback as proof that delivery is fixed for everyone.
A useful record for one loop test is: OBS preview at the boundary, local recording at the same time, Live Control Room preview, stream-health messages, and watch-page playback. You do not need to guess from the title or restart repeatedly. The sequence tells you which part to inspect next while keeping the test small enough to repeat after a single adjustment.
Inspect encoder and outbound connection if needed
If the source and OBS output appear sound but YouTube’s preview is not, review the encoder’s own status and output. Check for encoder errors and unusually high CPU load, and confirm that the stream is still being sent rather than disconnected. YouTube recommends comparing encoder output with the stream and checking a local archive; a healthy encoder view can point towards the outbound connection rather than the source. Treat that as a direction for investigation, not a conclusion that the network is definitely responsible.
Check the available upload capacity during the test and whether other activity on the same connection is using it. YouTube recommends leaving 20% upload-bandwidth headroom in its streaming guidance. This is a recommendation, not a guarantee of uninterrupted streaming or proof that a loop-timed black screen is a network fault. A network problem can disrupt the outgoing stream, but a repeatable failure exactly at the file boundary still warrants checking the source and playback behaviour first.
If you see dropped or unstable output, make a short test with fewer competing uploads and monitor the encoder and YouTube health messages. Do not buy networking equipment or change your whole encoding profile based only on a single black-screen report. First establish whether the same moment is black in OBS, in the recording, or only after YouTube receives the stream. If there is an actual disconnect, keep its time and error details separate from a continuous broadcast where only the picture disappears.
For a long-running recorded channel, the more important operational question is whether the video continues across the boundary without someone beside the computer to restart it. A workflow designed for a 24/7 recorded stream, such as the approach in running recorded lessons continuously, can be a useful comparison when deciding whether your current playback method is manageable. If leaving a computer on and watching for a stopped file is the recurring pain, StreamNeo removes that specific burden by turning an uploaded video into a continuing YouTube broadcast without keeping your own computer running. It does not establish that a particular file, loop setting, or YouTube delivery issue is fixed; test the actual file and monitor the incoming preview.

FAQ
Does YouTube repeat my prerecorded live video automatically?
No. When software sends a prerecorded file as a live stream, its playback source or playlist needs to continue supplying the video. Check the relevant control in the software feeding the stream; a viewer’s repeat control is not the same thing.
Which OBS setting should I check for a single yoga video?
For a single file played by an OBS Media Source, check Loop. For a playlist played through VLC Video, check Loop Playlist instead. Confirm the source type before changing a setting, and test through the file’s end.
What if OBS looks normal but YouTube is black?
Compare a local recording with YouTube’s Live Control Room preview and check stream-health messages. If the local output is normal but YouTube’s incoming preview is not, inspect encoder status and the outbound connection; these checks narrow the path but do not prove a single cause.
Should I disable “Show nothing when playback ends”?
First check whether that setting is enabled and whether the source is meant to remain visible after playback ends. OBS documents that it hides the source at completion, but changing it is not a guaranteed fix for every black screen. Retest one change at a time across the loop boundary.
