For one prerecorded video, add it to OBS as a Media Source and turn on Loop. For several videos, use a VLC Video source with a playlist and Loop Playlist enabled; the two source types handle different jobs.
Neither setting makes a broadcast uninterrupted by itself. You still need to connect OBS to YouTube Studio, check the encoder settings against your upload connection, and test the actual picture and sound before relying on the stream.
Choose one file or a playlist
Start with the schedule you want viewers to see. If the same long ambience video, devotional programme or information loop should repeat from beginning to end, a single-file Media Source is the simpler arrangement. If you need several clips to play in sequence, use VLC Video so OBS can manage a list of files.
| What you want to play | OBS source | Loop setting | Main consideration |
|---|---|---|---|
| One video, repeated | Media Source | Loop | The source repeats that one file when it reaches the end. |
| Several videos, in sequence | VLC Video | Loop Playlist | VLC must be installed, and playlist order needs checking. |
A playlist is useful when you want a news bulletin followed by notices, or a set of music and ambience videos to rotate. It also introduces more points to check: filenames and paths, order, different audio levels, and the transition from the last item back to the first. For a single item, those playlist controls add little value.
Choose a source based on the content, not on the assumption that one is more reliable. Both depend on OBS remaining active, the media being readable and the encoder connection holding up. If your goal is a channel that runs while your computer is off, the distinction between a looping file and a lasting broadcast matters: OBS controls playback on the machine running it, whereas a managed cloud workflow can remove the need to leave that computer on. StreamNeo is relevant to that specific computer-running burden: you upload a video, connect the YouTube stream key, and it can keep the broadcast running with your computer switched off.
Before choosing a source, make sure the video itself is ready. Check its beginning and end, confirm the audio is present, and decide whether it makes sense when a new viewer joins halfway through. A repeating video is not the same as a set of live segments: viewers can arrive at any point in the cycle, and YouTube may not preserve an indefinitely long broadcast as one archive.
Loop one file with Media Source
In OBS, select the scene that will carry the video, or create a scene for it. In the Sources dock, choose +, then Media Source. Give it a name that describes the content, such as “Evening bhajans” or “Shop information loop”, and select the local file. OBS supports common formats including MP4, MOV, MKV, AVI and WebM; see the OBS guidance on media sources for the source’s available options and supported formats.
In the Media Source properties, turn on Loop. OBS documents this as the control for playing the file again once playback completes; it is off by default. Do not look for a multi-file playlist in this source: Media Source is the direct choice for one file, and it does not loop a multi-file playlist.
Check the other source properties before closing the dialog. If the file should begin from its opening frame when the scene becomes active, decide whether Restart playback when source becomes active suits your scene behaviour. If you want the source to keep playing while hidden, review its visibility behaviour rather than assuming it continues. These settings can matter if your scene switches to an intermission or another view during the broadcast.
Resize the source in the preview so it fits the canvas. A video with a different aspect ratio may leave empty space or be cropped if you force it to fill the frame. A devotional image or local notice with text should remain readable, so preview the whole composition rather than judging it from the source properties alone.
Play the file in OBS and let it reach the end once during your test. Confirm that the next cycle starts, that the first frames are acceptable, and that audio resumes as expected. A loop control tells OBS what to do at file completion; it does not establish that every encoding, scene or file combination will transition without a visible pause.
If the video or audio does not behave as expected, check that the path still points to the intended file and that the source is visible in the active scene. If you move the file, relink it in OBS and run the end-of-file test again. For unattended use, a test that stops after a few minutes will not tell you whether the file can repeat cleanly.
Install VLC for a playlist source
For multiple videos, install VLC before adding the source. OBS says the VLC Video source requires VLC to be installed to appear in the source list. On a 64-bit OBS installation, use 64-bit VLC as specified in the OBS media source documentation. If VLC Video is missing, check the installation and matching architecture before troubleshooting the playlist itself.
In the intended scene, choose + in Sources and add VLC Video. You can then add multiple media items to its playlist. This is different from adding several Media Sources and stacking them in a scene: a VLC Video source plays its items as a playlist rather than showing all the files at once.
Add the actual local files you intend to use. If you organise them into a folder, keep that folder and its contents in place after setting up OBS. A playlist whose entries point to files that were renamed or moved will not be useful when the scene runs. Use filenames that make the intended sequence easy to recognise, particularly if you update the set later.
VLC Video also has visibility behaviour. OBS documents a default that stops playback when the source is not visible and restarts it when visible; the available behaviour can be configured to continue, pause or stop. Consider this if you have multiple scenes. A source that stops when hidden may begin again at the first item when you return to it, while a source that continues can reappear partway through a clip. Test the selected behaviour in the same scene arrangement you plan to use live.
Set playlist order and loop behaviour
Review the playlist from top to bottom and arrange the items in the order viewers should receive them. For example, a small business might put opening hours and a service overview before product clips, then repeat the list. A study channel might place a short introduction ahead of longer focus tracks. Consider whether an item should appear first every cycle or whether the sequence should simply continue from the end back to the beginning.
OBS documents Loop Playlist as on by default for VLC Video, while Shuffle Playlist is off by default. Check both controls rather than relying on defaults: enable Loop Playlist if the complete playlist should repeat, and leave Shuffle Playlist off if you need a fixed order. If you do want a varying order, shuffle changes the planned sequence, so confirm it is appropriate for the content and audience.
Play through the sequence in preview. Listen for changes in loudness between files, silence at clip boundaries, and any abrupt change in the type of content. A playlist can be technically ordered but still make an awkward programme if one clip has much louder audio or a different aspect ratio. Adjust the files or scene presentation where needed, then inspect the final-to-first transition as well as ordinary transitions.
For troubleshooting, test a short copy of the playlist before replacing the intended live scene. Remove an item temporarily or use a limited set of clips to verify the source works, then restore the full list and check it again. Do not leave a shortened test playlist in the final scene by mistake. If you are planning several property or product clips, the guide to playing multiple property tour videos in a YouTube Live playlist is a useful comparison of the same sequence-planning problem.
Connect OBS to YouTube Studio
Create or select a live stream in YouTube Studio’s Live Control Room. YouTube’s instructions for streaming with an encoder explain how to set up the stream and connect the encoder. In OBS, open Settings, then Stream, choose YouTube as the service, and enter or connect the stream credentials as directed by your chosen workflow. Treat the stream key like a password: do not show it in the video, screenshots or a public chat.
The stream URL and key tell OBS where to send the encoded feed and which stream it belongs to. YouTube describes the key as the address and password an encoder uses to send the feed. Confirm that the selected stream in Studio is the one you mean to broadcast; an old or different key can send the video somewhere unexpected or fail to connect.
For the video encoder, select a codec and output format that your computer can sustain. YouTube’s current encoder guidance lists RTMP/RTMPS ingest, H.264, H.265 or AV1 video, up to 60 frames per second, constant bitrate (CBR), and AAC or MP3 audio for RTMP/RTMPS. The bitrate recommendations vary by codec, resolution and frame rate, so choose the relevant row in YouTube’s live encoder settings rather than treating one figure as universal. YouTube recommends a two-second keyframe interval and says not to exceed four seconds.
As an example of how the table differs by format, YouTube lists a recommended H.264 bitrate of 14 Mbps for 1080p at 30 fps and 17 Mbps for 1080p at 60 fps; the corresponding listed minimums are 5 Mbps and 6 Mbps. These are YouTube encoder settings, not a promise that your computer or connection can maintain them. A higher frame rate and resolution need a compatible encoder configuration and sufficient sustained upload capacity. YouTube recommends selecting a quality compatible with your upload connection and checking its capacity with a speed test.
If your computer struggles to encode the selected format, lowering resolution or frame rate may be more practical than choosing a bitrate your connection cannot maintain. If you want to understand the hardware-side trade-off, see what NVIDIA NVENC does for live streaming. The important check is the result on your own OBS preview and YouTube stream health, not a preset selected without testing.
Encoder live streaming also depends on channel eligibility. YouTube says the channel must be verified and have no live-streaming restrictions in the past 90 days for encoder livestreaming. Confirm the current status in YouTube Studio and on YouTube’s official help pages; meeting a checklist does not guarantee that a particular broadcast will be approved or remain available.
Test the stream before relying on it
Do a preflight with the same scene, media, encoder settings and network path you intend to use. Start OBS streaming, then check the preview in Live Control Room before making the broadcast public or beginning the scheduled live workflow. YouTube’s live streaming troubleshooting guidance recommends testing and monitoring stream health and messages. A local OBS preview alone cannot show whether YouTube is receiving the feed correctly.
Use a checklist that follows the broadcast from source to viewer:
- Is the correct scene active, and does the video fit the canvas without hiding important text?
- Does the sound reach OBS and YouTube, at a level that is clear without clipping?
- Does a single file reach its end and begin again, or does the VLC playlist advance and return to its first item as intended?
- Does YouTube show a healthy incoming feed, with no messages that require you to change the encoder settings?
- Can the upload connection sustain the selected output while other household or business devices are in use?
For a channel that is meant to run overnight, test long enough to observe the relevant transitions and connection behaviour rather than only checking that the stream starts. A short test can establish that OBS connects, but it cannot establish that an extended broadcast will remain connected. Keep an eye on OBS and YouTube’s stream health indicators, and decide who will check them if the channel is meant to operate while you are away.
If the test buffers or drops, avoid changing several settings at once. Compare the selected bitrate with YouTube’s row for your codec, resolution and frame rate; check upload capacity; then adjust one variable and test again. If the video is fine locally but not in Studio, look at the encoder connection and messages. If it fails at a file boundary, return to the source or playlist behaviour. This separates playback problems from delivery problems.
For context on the difference between a machine-based setup and a cloud-hosted approach, the low-cost cloud server guide for an ambient YouTube stream in India discusses the separate operating trade-offs. A computer running OBS needs power, a stable connection and attention when something fails; a cloud workflow can remove the need to keep that personal machine on, but you still need to prepare and test the video, key and YouTube configuration.
Plan for what happens if the stream ends, too. YouTube says streams under 12 hours can be automatically archived, while streams longer than 12 hours may not be captured at all. Its DVR guidance also warns that rewind can be limited or unavailable for streams longer than 12 hours. If keeping a complete replay matters, use shorter broadcast segments and retain a local recording; YouTube’s archive guidance and DVR guidance explain the current limits. An archive is not a substitute for a copy you control.

FAQ
Does Media Source loop several videos?
No. Media Source is for a single file, and its Loop setting repeats that file. For multiple items, use a VLC Video source with a playlist and check Loop Playlist.
Why can’t I find VLC Video in OBS?
OBS requires VLC to be installed for the VLC Video source to appear. If you use 64-bit OBS, OBS specifies 64-bit VLC; install the matching version and reopen or check OBS before rebuilding the playlist.
Does looping guarantee an uninterrupted 24/7 broadcast?
No. Looping controls what happens when media playback reaches the end; it does not ensure that OBS, the computer, internet connection or YouTube ingest will remain active. Test the actual stream and monitor its health, especially before leaving it unattended.
Will YouTube archive a stream that runs all day?
Not necessarily. YouTube says streams under 12 hours can be automatically archived and longer streams may not be captured; rewind can also be limited on long streams. If the recording matters, keep a local copy and consider dividing the broadcast into shorter segments.
