If OBS shows a black screen while you are trying to loop a cartoon, first check that the correct media source is enabled and not hidden behind another source. Then confirm whether you are playing one file with Media Source or a playlist with VLC Video, and test the result in a short recording before relying on it live.
Looping controls whether playback starts again after it ends; it does not by itself resolve every black-screen problem. The symptom could be in the OBS preview, the programme output, a recording, or YouTube, so identify where it appears before changing unrelated capture settings.
Check whether the cartoon source is visible
In OBS, look in the Sources dock for the item that contains the cartoon. Find its visibility control, usually shown as an eye icon, and make sure it is enabled. A source can exist in the scene and still be invisible because its visibility is off; that is different from a video that is visible but has not started playing.
Select the source and inspect the OBS preview. Does a selection outline appear around a region where the cartoon should be? If not, the source may be hidden, positioned elsewhere in the scene, or outside the visible canvas. If you can see the outline but the area inside it remains black, keep going through the checks rather than assuming that the file or computer is at fault.
Look for any controls or scene changes that might alter visibility. A source may be enabled in one scene and hidden in another, and a scene transition can make it appear that the video has disappeared. Confirm that you are troubleshooting the scene currently shown in the programme output, not a different scene selected for editing.
For a useful first comparison, note whether the source preview itself is black, whether the full OBS preview is black, or whether only YouTube shows a black picture. These are different observation points, not proof of a particular cause. The distinction will help you avoid applying Game Capture or display-capture remedies to a local media file that is simply behind another layer.
Check for sources covering the video
OBS displays sources according to their order in the Sources list: items higher in the list can sit above items below them. A full-canvas colour source, image, browser source, or another video can therefore cover the cartoon while the cartoon remains enabled and playing underneath. Check what is listed above the media source before rebuilding your scene.
If you find a covering source, test by temporarily hiding it. If the cartoon appears, you have found a layer-order issue. You can then put the sources back in the intended order, rather than deleting or recreating them. Avoid leaving a temporary test change in place without checking how the finished scene should look.
Also check the selected source’s position and size in the preview. It may be outside the canvas, reduced to a small area, or covered only where the cartoon is expected to appear. Dragging and resizing can be useful for diagnosis, but note the original layout if the scene has carefully placed text, logos, or borders.
A simple diagnostic order is more useful than random changes: enable the cartoon source, check its position, then hide likely covering layers one at a time. If that does not change the picture, restore the scene and move on to the source type and playback settings. OBS’s guide to sources and their order is a helpful companion when you are arranging a cartoon scene; use the official OBS Sources Guide for the source visibility and layering behaviour.
Loop one file with Media Source
For one local cartoon file, use OBS’s Media Source rather than setting up a playlist unnecessarily. In the source properties, confirm the intended file is selected and inspect the Loop control. OBS documents this setting as replaying the file after playback completes. It controls what happens at the end; it cannot make a hidden source visible or move it above a covering layer.
If the source is already a Media Source, open its properties and verify the file path points to the cartoon you meant to use. A moved or renamed file can leave the source pointing somewhere other than the current asset. The dossier of official OBS guidance covers common media types, but your specific file and version may still matter, so do not assume a black preview proves a particular codec problem.
For diagnosis, temporarily test with a short, known local video if one is available. If that appears in the same source and scene, it narrows the question towards the original file or its selection; it does not establish why the original fails. If both files remain black, return to visibility, layer order, and where the black picture is observed.
Use Loop for continuous replay only after confirming that ordinary playback works. First see whether the file can display at all, then let it reach the end and verify that it begins again. That separates a display problem from an end-of-file behaviour problem. A loop that resumes successfully in the preview is useful evidence, but it is not yet a test of the complete YouTube output.
If your plan is a continuous channel rather than a short scheduled session, you may also want to compare the practical limits of a long YouTube live stream. That is a separate question from whether OBS can display this particular file; solve the scene and playback problem first.
Use VLC Video for a playlist
A playlist is a different arrangement from a single local file. OBS’s VLC Video source can play a playlist and provides a Loop Playlist setting. VLC must be installed for this source to work, and the OBS guidance specifies that 64-bit OBS requires 64-bit VLC. If you installed or updated one without the other, check their architecture compatibility before changing scene layers or reinstalling OBS.
Inspect the playlist entries themselves. Confirm that they point to files that are still available at those locations and that the cartoon you expect is included. A playlist can be present in the source properties but still be empty in practical terms if its entries are wrong. Check playback with a deliberate test before concluding that the loop option is responsible for a black picture.
Do not substitute the VLC Video instructions for a Media Source just because both are used for video. For one file, Media Source is the direct route. For a sequence of files, VLC Video is the documented playlist route. Choosing the matching source makes the controls easier to interpret and gives you a smaller number of things to diagnose.
If you are building a playlist-based show, this guide to continuous podcast playback in OBS may help you think through a sequence of files. Its subject is audio-led playback, so use OBS’s own Media Sources documentation for the actual Media Source and VLC Video properties.
Confirm VLC and OBS architecture compatibility
If you are using VLC Video, confirm that VLC is installed on the computer running OBS. Then check whether the two applications match in bitness when you are on a 64-bit setup. The OBS Media Sources guide states the 64-bit VLC requirement for 64-bit OBS. If you do not know which build you installed, check the application’s About information or the installer details rather than guessing.
This check only applies to VLC Video. A single-file Media Source does not depend on VLC in the same way, so installing VLC is not a general remedy for every black screen in OBS. Likewise, changing GPU settings because an online guide mentions them is not a first step for a local media source.
Keep troubleshooting specific to the source that produces the image. OBS’s laptop troubleshooting article discusses dual-GPU and display-capture cases; it should not be treated as evidence that a local cartoon file has a GPU mismatch. The Game Capture troubleshooting guide is for Game Capture. Use those pages only if the black image actually comes from the corresponding capture source.
Test with a short recording or stream
Before the next live session, make a short local recording or a test stream and play it back. OBS recommends testing settings before the first stream or recording in its Quick Start Guide. A visible image in the editing preview is useful, but the recording or test output checks more of the path you intend to use.
Watch the test through the end of the file if you are checking a single-file loop, or through the playlist transition if you are checking VLC Video. Look for the cartoon, any change to black, and whether playback resumes. Also listen if sound matters to the channel: a picture test alone does not confirm the audio arrangement.
Keep the test short enough to review, but long enough to exercise the behaviour you are checking. There is no fixed duration that suits every file; the important point is to observe the relevant playback or transition and inspect the resulting output. If your cartoon file is long, you can use a separate short test clip to verify scene visibility and recording output, then separately check the real asset before going live.
A successful recording is not a guarantee that YouTube will display the same result in every circumstance. It does, however, help distinguish a scene or OBS output issue from a problem that first appears later in the delivery path. If you test a live output, use an appropriate test arrangement for your channel and check the result there before relying on it for viewers.
For a channel intended to run continuously, a computer that must remain on and OBS that must keep playing are operational dependencies beyond this immediate display fault. If that is your wider concern, compare the trade-offs of running a continuous stream with systemd on Ubuntu; it is a different setup and not a fix for a hidden or incorrectly configured source.
Narrow down where the black screen begins
Check the picture at three points: the media source or scene preview in OBS, the OBS recording or programme output, and the YouTube result. Write down the first point where it turns black. This is a practical way to narrow the investigation, not an official OBS decision tree, and the result does not by itself prove a root cause.
If the source preview is black, revisit the selected file or playlist, source type, visibility, and playback. If the source looks right but the full scene is black, investigate the scene, layers, and output view. If a local recording is correct but the YouTube result is black, the issue appears later than that recording point; check the actual live output and current YouTube guidance rather than changing the local media source at random.
If only Game Capture or Display Capture is black, then consult the source-specific troubleshooting material. A local cartoon loaded from disk is not the same as a game image or a captured monitor. Applying a fix intended for the latter can introduce new changes without addressing the original symptom.
Make one change at a time and repeat the same test. If you change the source type, reorder several layers, replace the video, and alter capture settings together, you will not know which change mattered. Keep a note of the original settings and restore unrelated changes when a test does not help. If the problem persists, gather the OBS version, operating system, source type, file arrangement, and the point where black first appears; these details make the next troubleshooting step more specific.
When the recurring difficulty is that a personal computer must stay on with the broadcast running, a cloud-run file stream can remove that particular burden. StreamNeo turns an uploaded video into a YouTube live stream, so you can switch off your own computer after preparing the file and channel; it does not diagnose or repair an OBS scene, and it is YouTube-only.
If the local test works and the channel is ready, compare the operating choices before committing.

FAQ
Should I turn on Loop to fix a black screen?
Loop makes a file play again after it finishes, but it does not fix visibility, layer order, or an incompatible VLC Video setup. First establish that the cartoon displays in OBS, then test the end-of-file behaviour. A black picture may have a different cause, so do not treat looping as a universal fix.
Should I use Media Source or VLC Video?
Use Media Source for one local file and inspect its Loop control. Use VLC Video when you need a playlist, with VLC installed and the bitness requirement met for your OBS setup. Choosing the source that matches the media arrangement keeps the test focused.
What if OBS looks right but YouTube is black?
Check a short recording or test output and note where the picture first disappears: source preview, OBS output, or YouTube. A correct local recording narrows the issue to a later point, but does not identify the cause on its own. Consult current official guidance for the part of the delivery path where the symptom appears.
Do I need to rebuild my OBS scene?
Not as a first step. Check visibility, source position, and sources above the cartoon before replacing anything. If you do make changes, make them one at a time and test again so you can tell what affected the picture.
