To stream a prerecorded video from OBS to YouTube without a microphone, add the file to an OBS scene as a Media Source, enable Loop, and disable or mute the microphone input. The clip’s own soundtrack is a separate audio source: keep it active if you want viewers to hear it.
OBS sends the encoder feed to YouTube, but starting OBS does not itself publish a scheduled event. Create or schedule the event in YouTube Live Control Room, start streaming from OBS, check the incoming preview, then select Go live in YouTube when the event is scheduled.
Prepare the video and the YouTube channel
Choose the file you intend to broadcast and play it locally from beginning to end. Confirm that both the picture and any soundtrack are the versions you want viewers to receive. If the file has a long silent opening or closing, account for that when testing: OBS will repeat the whole file, not just the section you happen to prefer.
The file needs to be available on the computer running OBS. Keep it in a stable location rather than moving it after setting up the source, and avoid relying on a removable drive that may be disconnected. The OBS Media Sources guide lists common video formats OBS can use; if a file does not load or plays incorrectly, check its format and try opening it in a local player before troubleshooting the stream.
Check your YouTube channel’s live-stream eligibility before planning a broadcast. YouTube’s eligibility guidance says a channel must be verified and must not have had a live-streaming restriction in the previous 90 days. Those are platform requirements, not a guarantee that a particular account is ready; check the current official page and the controls in your own Studio account.
Decide whether the event should be public, private, or unlisted, and prepare its title and description. YouTube’s event settings determine who can find or watch the broadcast. For a quiet technical test, an unlisted or private event may be more appropriate than a public one, but confirm the current visibility behaviour in Studio before sharing a link or relying on privacy settings.
If your goal is a playlist rather than one file repeated from beginning to end, a Media Source is not the only OBS choice. OBS documents VLC Video as the source intended for playlists, and VLC must be installed for that source to appear. For a playlist workflow on a modest computer, see this guide to running an OBS YouTube playlist stream on a low-cost PC in India. This article focuses on the simpler case: one local video looping continuously.
Add the file to an OBS scene
Open OBS and select an existing scene for the broadcast or create one. In the Sources panel, use the plus button and choose Media Source. Give the source a clear name, such as “Main loop”, so it is easy to identify later if the scene contains other items. Select the local-file option and browse to the video.
Once it loads, check the OBS canvas. If the video appears too small or is cropped, adjust its transform so it fits the canvas in the way you intend. The right choice depends on the video and the output shape: stretching a narrower clip may distort faces or lettering, while filling the screen may crop parts of the picture. Use the preview to judge the result rather than assuming one fit option suits every file.
Pay attention to what is selected in Sources. OBS layers sources, so a title card, image, or browser source above the video can cover it. Temporarily hide other sources if needed, then confirm that the clip is visible and moving. If the source is not visible, check that it is enabled, that the file path is still valid, and that another layer is not covering it.
A single-file loop keeps the same clip repeating. If you need different videos in sequence, use an OBS playlist source or another deliberate playlist workflow instead of adding multiple overlapping Media Sources and hoping they take turns. The distinction matters at 2 a.m.: one source with a loop is easy to inspect, whereas an improvised scene can leave you with a frozen image or the wrong layer on screen.
Enable looping and check playback
Open the Media Source properties and enable Loop. OBS’s source documentation notes that looping is a property of the media source; it is not a YouTube setting. A newly added source may not have looping enabled, so verify the checkbox rather than assuming the file will repeat. Let the video reach its end during a test and watch for it to begin again.
The transition at the loop point is whatever is present at the end and beginning of the file. If there is a black frame, an audio gap, or a noticeable jump, OBS will repeat that too. You can improve the result by editing the source file, but do not mistake the source’s loop setting for a crossfade or playlist transition: it simply plays the file again.
Check what happens when the source is hidden or the scene changes. For a simple one-scene broadcast, keep the media source visible in the active scene. If you use several scenes, switch between them in a test and make sure returning to the loop behaves as intended. OBS source behaviour can depend on source properties and visibility, so validate your own setup rather than assuming playback will continue in the background.
For a nature or devotional channel built around repeating material, the content needs to work at the seam as well as in the middle. This overview of rain, nature and ambience loops for a 24/7 relaxation channel is useful when you are deciding whether a single repeated file suits the viewing experience or whether you need a broader rotation.
Disable the microphone without muting the clip
OBS installations may capture a microphone by default. Inspect the Audio Mixer before broadcasting rather than assuming no microphone is active simply because you did not deliberately add one. If a microphone or Mic/Aux channel is present, mute it in the mixer or disable the configured microphone device under Settings → Audio. You can also remove or disable a microphone input source in the scene.
The microphone and the Media Source’s audio are not the same control. Muting the microphone prevents that input from reaching the mix; it does not automatically mute the soundtrack embedded in the video. If you want music, speech, bells, or other clip audio to be heard, leave the Media Source audio unmuted. If you want a silent video, mute the media source deliberately as a separate decision.
Watch the mixer while the clip plays. A microphone meter should remain inactive when the room makes sound, while the Media Source meter should move if the video contains audible sound and its audio is enabled. The mixer is a useful indication, but it does not replace listening to a recording or a test stream. Listen on another device if possible, because hearing playback locally from the source is not proof that the encoded feed includes it correctly.
If you add an Audio Input Capture source to a scene, check that the same device is not also enabled globally in Settings → Audio. OBS warns that capturing a device in both places can create echo. For more detail on choosing and managing audio inputs, consult the OBS Audio Sources reference.
A practical configuration is often one active Media Source audio channel and no active microphone channel. That gives you the clip soundtrack without room noise, keyboard clicks, or accidental conversation. If the channel is meant to be silent, mute the Media Source too and confirm the silence in the actual outgoing feed.
Connect OBS to YouTube Live Control Room
In YouTube Studio, choose Create → Go live. You can start an encoder event from the Stream tab or use Manage to schedule one. The exact labels may change, so follow the current YouTube encoder setup instructions if your Studio screen differs.
In OBS, open Settings → Stream. If YouTube is available as a service, select it and follow the connection or key workflow shown there. Alternatively, take the stream URL and stream key from YouTube Live Control Room and enter them in OBS’s server and key fields. The key connects the encoder feed to your event and should be treated like a password: do not show it on screen, publish it, or include it in a public screenshot.
If you think the key has been exposed, reset it in YouTube and update OBS with the new value. Avoid pasting it into a chat or into notes that will be shared with viewers. If you have lost OBS settings after replacing a profile, this guide to recovering a YouTube stream key after an OBS profile change covers that particular recovery problem.
Set the title, description, visibility, and other event details in YouTube. Then start streaming in OBS. For an immediate event, use the Live Control Room’s controls to begin the broadcast when YouTube indicates the feed is ready. For a scheduled event, starting OBS sends the encoder feed, but the event is not necessarily live to viewers yet: wait for the preview to appear and use Go live in YouTube when you are ready.
At the end, stop or end the broadcast through YouTube’s Live Control Room and stop the feed from OBS. This makes the closing action explicit and helps you confirm that the event has ended rather than leaving the encoder sending a feed unintentionally. Check YouTube’s current interface for the precise controls, especially if you are managing a scheduled event.
Check encoder settings and the connection
For a stable feed, the computer’s upload connection must sustain the chosen output bitrate. YouTube recommends RTMPS for encrypted delivery and publishes encoder recommendations in its live encoder settings. That page covers codec, frame rate, keyframe interval, and bitrate combinations. Use the current official table for your chosen resolution and codec rather than treating a recommendation for one format as universal.
A video loop may be visually simple, but it still needs to be encoded and uploaded continuously. A higher output setting can use more upload capacity and may be less tolerant of a busy or inconsistent connection. Run a speed test close to the computer and network you will use, then choose settings that the connection can sustain. Leave room for ordinary household or office traffic rather than assuming every bit of measured upload capacity is available to OBS.
YouTube’s published bitrate figures are recommendations, not measurements of your connection or promises about the result. If you change codec, resolution, or frame rate, revisit the relevant row in the current table. Keep the settings consistent with the file and your connection; a static-looking scene does not remove the need to send a live encoder feed.
A useful workflow for a channel that runs from a home computer is to separate the content setup from the reliability plan. This guide to OBS settings for a continuous YouTube podcast stream on a home computer in India discusses the trade-offs of running a long broadcast locally. OBS requires the computer and connection to remain available; if power, internet, or the machine stops, the encoder feed can stop too.
Preview, test, and then start the event
Before an audience depends on the stream, test the complete path: the file, OBS scene, audio mix, encoder connection, and YouTube preview. OBS’s Quick Start Guide recommends testing before a real broadcast, and YouTube’s live-streaming tips advise checking the preview and monitoring audio and video quality.
Start with a short local check. Confirm that the video appears correctly in the OBS canvas, the Media Source audio meter behaves as expected, and the microphone meter remains inactive. If you can, record a short sample in OBS and play it back with headphones. This can catch a muted soundtrack, an unwanted microphone, or a framing issue without first making a public event.
Then test the YouTube feed. Start streaming from OBS and wait for Live Control Room to show the incoming preview. Check the picture and listen to the preview or a test viewer’s playback. If the event is scheduled, do not click Go live until the preview and intended audio are right. Starting OBS alone does not complete a scheduled broadcast.
Let a test run long enough to verify the loop point, not merely the first few seconds. Confirm that the beginning follows the end cleanly, the clip soundtrack returns as expected, and no microphone audio is being sent. Also check for connection warnings or a frozen preview. If anything is wrong, stop the test, adjust one setting at a time, and repeat it so you know which change fixed the issue.
For a first public broadcast, keep the Live Control Room visible so you can notice a lost signal or a change in stream health. YouTube can transcode the incoming feed for viewers, so what you see on the local OBS canvas is not the only thing to verify. A complete test means checking the YouTube-side preview or playback as well as the scene inside OBS.
Plan for the limits of a local OBS loop
An OBS loop is straightforward when you are nearby to launch it and monitor it. For a long-running channel, however, the broadcast depends on the computer staying on, OBS continuing to run, and the connection remaining usable. Automatic operating-system updates, power interruptions, sleep settings, and a changed network can all interrupt that chain. Configure the machine not to sleep during the broadcast and consider how you will detect and recover from interruptions.
YouTube’s encoder instructions state that streams under 12 hours are automatically archived. Do not rely on that behaviour for a stream at or above that duration; if an archive matters, check the current official guidance and consider a separate recording or shorter broadcasts. An archive is not a substitute for keeping your original video file.
If managing a powered-on computer and recovering OBS after a drop is the pain point, StreamNeo turns an uploaded video into a YouTube live stream without requiring your computer to keep broadcasting. You provide the video and YouTube stream key, and the broadcast can continue from the cloud with monitoring and automatic restarts if it drops. It is YouTube-only, so decide whether that fits your channel and workflow rather than assuming it replaces every OBS use case.

FAQ
Does muting the microphone remove the video’s soundtrack?
No. The microphone input and the Media Source audio are separate. Mute or disable the mic channel, then leave the Media Source unmuted if you want the clip’s soundtrack in the broadcast.
Does pressing Start Streaming in OBS make a scheduled YouTube event live?
Not by itself. OBS sends the encoder feed to YouTube; for a scheduled broadcast, wait for the Live Control Room preview and select Go live there when you are ready.
How can I be sure the loop and audio work before viewers arrive?
Run a complete test through YouTube’s preview or a test event, and let the file reach its loop point. Check the picture, listen for the intended clip audio, and confirm the microphone meter is inactive; a short local recording is also useful.
What if I want several videos to rotate rather than one clip repeating?
Use an OBS playlist workflow such as VLC Video rather than expecting a single Media Source loop to rotate files. Check the current OBS documentation and test the playlist transition, audio, and visibility behaviour before going live.
