To loop a video on YouTube Live, turn on Loop in the encoder that plays the file; in OBS, that means adding a Media Source and enabling its Loop setting. Then connect OBS to the stream URL and key from YouTube Studio, treating the key as a password rather than as part of the playback setup.
The loop setting controls what OBS sends after the file ends. YouTube receives the encoder’s outgoing feed; it does not receive a loop instruction from Studio. A repeated file also does not make the broadcast self-sustaining: OBS still has to be running and sending the feed.
Create or select a YouTube Live stream
Open YouTube Studio and go to the Live Control Room. Create a stream or select one you have already prepared, then check the stream details and intended visibility before you connect OBS. YouTube’s encoder streaming instructions describe the steps for sending an encoder feed and taking it live.
If this is your first time using live streaming, allow for YouTube’s activation process before you plan a broadcast. YouTube says first-time activation can take up to 24 hours. Eligibility and access can change, so check the current live streaming requirements for your channel rather than assuming that creating a stream means it can go live immediately.
Decide whether the stream should be public, unlisted or private. That choice controls who can find or watch the broadcast; it is separate from whether the stream key is secret. A private stream is not a substitute for protecting the key, and keeping the key private does not make a public broadcast private.
Before using a file in a loop, check that you have permission to broadcast its video and audio. Replaying a file does not change the rights situation. If the stream is for a shop, a devotional channel or a study station, verify that the music, footage, images and any other material are authorised for the intended use.
For a scheduled stream, OBS sending a feed and YouTube publishing it are distinct steps. Follow the Live Control Room prompt: YouTube’s encoder guidance says to wait for the preview and then select Go live for a scheduled broadcast. Check the preview and the visibility setting before making the stream public.
Find the stream URL and key in Studio
In the Live Control Room, open the stream’s settings and locate the stream URL and stream key. You will enter both in OBS later. The URL identifies where the encoder connects; the key lets YouTube accept the feed for your channel. YouTube describes stream keys as password-like credentials, so handle the key accordingly.
Copy the values directly from Studio when you are ready to configure the encoder. Avoid placing them in a shared document, chat, task ticket or public setup guide. If you need to keep a private note for a genuine operational reason, restrict access to people who need it and remove the note when it is no longer needed.
You do not need to put either value into the video file or into the Media Source properties. The playback configuration and the connection credentials are separate tasks: first tell OBS what media to play and whether to repeat it; then tell OBS where to send its output.
If you reuse a previous stream’s settings in Studio, review the metadata, visibility and key before starting. YouTube notes that reusing stream settings can carry over the previous stream’s metadata, settings and key. That can be convenient, but it means an old title or unintended visibility may persist unless you check it.
Add a Media Source in OBS
In OBS, select or create the scene you intend to use for the broadcast. In the Sources panel, add a Media Source, give it a name that makes sense to you, and choose the local video file. OBS’s media sources guide explains the available source types and their properties.
A Media Source is a straightforward choice when you want to repeat one local file. The file plays within the scene, while OBS composes the output that goes to YouTube. It is not necessary to buy a capture card just to play a local file: the documented workflow uses OBS and a media source. A capture card has other uses, such as bringing in an external video signal, but it is not the loop control.
After selecting the file, check that it appears in the scene and is framed as intended. If the source is larger or smaller than the canvas, use the OBS transform options to fit it; confirm the result in the preview. Make sure any text, logo or other overlay remains legible against the footage. For a shop promotion, for example, check that the product and price are not clipped at the edge of the frame.
The video source is only one part of what viewers receive. If the file has audio, listen to the OBS preview and confirm that the right audio source is active and at a sensible level. A loop can repeat both picture and sound; it cannot correct a quiet recording, a sudden volume change or a silent section in the file.
Enable Loop for the file
Open the Media Source properties and turn on Loop. OBS defines this setting as replaying the media after it completes; it is off by default. With Loop enabled, one file begins again at its end while the scene remains active. This is the setting that makes the file repeat, not a setting in YouTube Studio.
Play the source and observe what happens when it reaches the end. Check the transition from the final frame back to the beginning, and listen for an abrupt cut or gap in the audio. If the ending is jarring, adjust the media file in an editing application and test it again; the Loop checkbox repeats the file as supplied and does not add a fade or repair its ending.
For a sequence of separate files, consider OBS’s VLC Video source instead of stacking several Media Sources. Add the files as a playlist and enable Loop Playlist to repeat the sequence. OBS documents VLC Video as a media source that depends on VLC being installed; when OBS is 64-bit, OBS says to use 64-bit VLC. This adds a software dependency, so confirm the source works before relying on it for a scheduled broadcast.
| Playback approach | What repeats | What to check |
|---|---|---|
| Media Source with Loop | One selected local file | Loop is enabled, and the file’s ending returns cleanly to its beginning |
| VLC Video with Loop Playlist | A playlist of files | VLC is installed with the matching architecture, and the playlist order is correct |
If you need different clips in a deliberate order, decide that order before going live and test the playlist from its first item to its return to the beginning. For guidance on rotating separate programmes, see how to run two podcast playlists in rotation on one YouTube Live stream. A playlist is not the same as a single file loop: check what happens when one item is longer, shorter or has different audio levels from the next.
Enter the encoder connection details
Once playback behaves as intended, configure OBS to send the scene to YouTube. In OBS, open Settings and go to the Stream section. Choose YouTube as the service, then enter the stream URL and key from the Studio stream settings if you are using the custom server or key fields. The exact controls can vary by OBS version, so use the current interface and YouTube’s encoder steps as your reference.
Keep this step distinct from setting up the Media Source. The Media Source’s Loop option controls repetition; OBS’s Stream settings control the outgoing connection. YouTube does not send OBS a loop setting, and copying a stream key into OBS does not configure the file to repeat.
Before starting, check that the correct scene is selected, that the video and audio are visible in the OBS preview, and that the intended YouTube stream is open in Studio. Start streaming from OBS. For a scheduled broadcast, wait for the preview in Live Control Room and use its Go live control when the stream is ready, as YouTube instructs. Do not assume that clicking Start Streaming in OBS alone publishes a scheduled event.
If there is no preview, verify the selected service, URL and key, then check that OBS is actually sending. Avoid posting a screenshot of the settings while troubleshooting: it may expose the key. You can describe the error or share a redacted screenshot instead. Redaction should cover the entire credential field, including any visible characters, not just its middle.
Keep the stream key private
Treat the stream key as a credential that can allow an encoder to send a feed to your channel. Paste it only into the appropriate encoder field. Never include it in a screen recording, screenshot, public post, tutorial video or the live output itself. OBS is the place where you enter the value, not a guarantee that the value cannot be seen by someone with access to the computer or its settings.
Before recording your desktop for a tutorial or demonstration, close settings that show the key and inspect the recording before publishing. The same care applies when asking for help: crop or cover the credential field before sharing an image. A stream preview is useful for checking the picture and sound, but it is not a reason to reveal account credentials on air.
Limit channel administrative access to people you trust. YouTube’s streaming safety tips recommend taking care over who has access to a channel. In a small team, agree who is allowed to configure broadcasts and who can change account settings; avoid sending the key to a wider group simply because several people want to see the setup.
Keep access to the computer and channel account in mind as well as the key itself. If a shared editing workstation is used by more than one person, sign out when appropriate and make sure access is limited to the people responsible for the stream. Do not store a visible copy of the key in a scene name, source label or on-screen graphic.
Visibility and credential secrecy solve different problems. Public, unlisted and private describe who can watch through YouTube; they do not change what the stream key is for. For example, an unlisted broadcast may not be publicly discoverable in the usual way, but anyone who has its viewing link may be able to watch. Review YouTube’s current settings before deciding who should see the stream.
An OBS setup on a computer you control is useful if you want to adjust scenes, add overlays or manage several sources yourself. It also means the encoder depends on that computer and its running session. If your specific difficulty is keeping a prerecorded broadcast running while your computer is off, the always-on streaming trade-off is a separate operational question from how OBS loops a file. StreamNeo removes the need to leave your own computer running for an uploaded video broadcast, which addresses that particular handoff; it does not change YouTube’s key or visibility rules.
Reset or replace a compromised key
If you think the key has been exposed, replace it rather than relying on deleting the post or hiding the screenshot. In YouTube Studio’s Live Control Room, open the stream settings and use the reset option for the key. YouTube says a channel owner or manager can reset it; if you do not have that role, ask the appropriate channel administrator to take the step.
After the reset, update the encoder with the replacement key before trying to send the feed again. An old key will no longer be the credential you intend to use, so make sure OBS is not still configured with the previous value. If you use more than one encoder or saved profile, review each one that could still contain the old key.
Then test the connection privately or with the visibility you intend, checking the Studio preview before publishing. Review who has access to the channel and remove any unnecessary access. Resetting the key addresses the exposed credential; it does not by itself resolve an account-access problem or make an unintended public broadcast private.
Plan for the broadcast, not just the loop
A file can repeat correctly while the broadcast still stops if OBS closes, the computer loses power or the internet connection fails. A loop is a media playback setting, not an uptime guarantee. If the channel must stay live overnight, decide who will notice a problem and what they can do, and test the complete path from file playback to YouTube preview before relying on it.
Think separately about the live feed and the archive. YouTube says streams under 12 hours can be automatically archived, while streams longer than 12 hours may not be captured at all; it recommends keeping a local recording as a backup. If the recording matters, make a local preservation plan instead of assuming that a continuous loop will always produce a complete YouTube archive.
A local recording also needs room and a check that it is actually being written. Test it before the broadcast, then verify that the file opens and includes the expected audio and picture. An archive can help if viewers want to watch later, but it is not a substitute for checking the live stream itself.
Consider how you will handle changes to the content. A single file is simple to inspect, but any correction requires replacing or editing that file and checking the new version. A playlist can make rotation easier, but it gives you more items and transitions to verify. If you are planning a long recorded music or language stream, the setup guide for recorded language lessons offers a related way to think through content order and the always-on format.
Before committing, compare the operating options on the pricing page. When the file and channel are ready, start free — 24-hour trial, no card.
FAQ
Does YouTube Studio have a loop setting for my video?
No. You configure repetition in the encoder that plays the file. In OBS, enable Loop in the Media Source properties for one file, or use a VLC Video playlist with Loop Playlist for a sequence.
Can I safely show my stream key in an OBS tutorial?
No. Treat it like a password: do not show it in a recording, screenshot, post or live output. OBS is where you enter the key, but you should not assume the software conceals it from anyone who can view the relevant settings.
Will the stream keep running if my computer switches off?
Not with a local OBS session sending the feed: the encoder needs to be running to send video to YouTube. A loop only repeats the media while that playback and broadcast setup is active.
What should I do if someone has seen my key?
Reset it in YouTube Studio’s Live Control Room, then replace the old value in OBS and in any other encoder profile that used it. YouTube says only a channel owner or manager can reset the key.
