To run a prerecorded video as a YouTube Live loop on Airtel broadband, play it from OBS Studio, enable the Media Source’s Loop property, and send the stream to YouTube using the URL and key from YouTube Studio. Your usable upload capacity—not the name of your Airtel plan or its advertised download speed—determines what bitrate you can try.
You cannot infer a particular result from the provider or plan alone: location, network conditions, other household traffic and plan terms all matter. Test the actual computer and connection, leave upload headroom, then check a private or unlisted broadcast before relying on the loop.
What you need before starting
You need a computer that can play the local video and run OBS Studio, an internet connection, a YouTube channel allowed to stream, and the video file itself. Keep the computer awake and connected for the whole broadcast. A loop in OBS repeats the source; it does not keep streaming if the computer shuts down, OBS closes or the connection drops.
Check channel eligibility before preparing a scheduled broadcast. YouTube’s live streaming eligibility guidance says the channel must be verified and must not have live-streaming restrictions within the preceding 90 days. YouTube’s getting-started guidance also says people must be at least 16 to live stream. If this is the channel’s first live stream, enable the feature in advance: activation can take time, so do not leave it until the planned start.
Choose a video you have the right to broadcast, including its music, images and any other included material. Check that it plays correctly on the computer before building the scene. If the file is awkward to decode or the computer struggles during playback, first see how to prepare video files for a 24/7 YouTube stream on a low-end PC. A simpler file can make it easier to distinguish a playback problem from a network problem.
Also decide whether you are repeating one file or need a playlist. A single file suits the Media Source workflow below. For several files, OBS offers a VLC Video source with a Loop Playlist option; the playlist route has different setup details. This guide focuses on one local file so you can check the repeat behaviour before going live.
Add a local video as an OBS Media Source
Open OBS Studio and create a scene for the broadcast. In the Sources panel, use the add control and choose Media Source. Give it a recognisable name, such as “Main loop”, so that you can identify it if you later add a title card or other source.
In the source properties, select the option to use a local file, browse to the video and open it. The preview should show the picture. If it is blank, confirm that you selected the right file and that it plays outside OBS. Interface labels can change between OBS releases; consult the current OBS Media Sources guide if the property names do not match.
Make the video fit the canvas. Select the source in the preview and use OBS’s fit-to-screen transform, then inspect the edges for cropping or unwanted borders. Check the canvas orientation and output resolution against the video. A vertical video on a landscape canvas, for example, may leave empty space at the sides; decide whether that is acceptable rather than stretching the image out of shape.
Check sound as well as picture. If the file should include audio, watch the OBS audio meter while it plays and listen on the computer. If there is no sound, check the source’s audio settings and whether the file has an audio track. If the file should be silent, make sure desktop audio or another source is not unintentionally adding sound. Do not assume that the preview alone confirms that viewers will hear the intended mix.
Let the video play long enough to see what happens at its ending. This gives you a baseline before you enable repetition: note whether the last frame, sound or transition has a pause or abrupt cut. OBS documents Media Source as a way to play a media file within a scene, with properties that control its playback. The free software comparison for looping nature videos covers other ways to approach looping if OBS is not the workflow you need.
Enable the source’s Loop property
Open the Media Source properties and tick Loop. OBS will restart the file when playback reaches its end, so the source continues to repeat while the scene is active. This is a playback setting in the encoder; YouTube receives the outgoing video signal and does not need a separate loop instruction.
Test the end-to-start transition in the preview. A file with a silent gap, a black frame or a sudden change in sound will repeat that feature every time it reaches the end. If you need a seamless transition, edit and review the source file rather than expecting Loop to remove a gap that is already in the media. For a collection of tracks or clips, OBS’s VLC Video source can play a playlist and restart it with Loop Playlist; see how to stream different videos in a YouTube Live playlist without a gap for that distinct use case.
Keep the source file in a stable location. If you move, rename or remove it after selecting it in OBS, the source may no longer load as expected. Before a long session, restart OBS once and confirm that the scene still opens with the correct file, image and audio. That check catches a missing-file issue before it becomes an empty or frozen-looking broadcast.
A loop is not itself a continuous-broadcast guarantee. OBS must keep running, the computer must remain powered and the connection must carry the stream. The repeat setting only determines what happens when the local file finishes playing.
Get the YouTube stream URL and key
In YouTube Studio, choose Create → Go live and open the Stream workflow in Live Control Room. Create a new encoder stream or select a scheduled one. YouTube provides a server URL and stream key for the encoder to send its signal to. The exact on-screen wording can shift, so follow the current interface rather than relying on an old screenshot.
In OBS, open Settings → Stream and select the service and server settings appropriate for YouTube. Paste the server URL and stream key into the matching fields. Use YouTube’s RTMPS URL where it is offered and supported by the encoder; YouTube describes RTMPS as encrypted ingestion. Do not display the key in a public screen recording, put it in a post, or share it with someone who should not control the stream. Treat it like a password. If it is exposed, replace or reset it through YouTube Studio.
A stream key connects the encoder output to the selected YouTube stream. Copying the wrong key, pasting spaces or using details for a different scheduled event can prevent the preview from appearing in the place you expect. If OBS reports a key error, check the selected event and the copied fields before changing unrelated video settings. The stream key troubleshooting guide for a 24/7 Indian music channel is useful if the connection details are rejected.
Save the OBS settings and return to the scene. Do not start a public event merely to see whether the key works. A private or unlisted test lets you inspect the encoder preview and sound without presenting an unfinished broadcast to the channel’s audience. Check YouTube’s current visibility options and select the one suited to your test.
Test upload capacity and stream health
Measure upload capacity from the computer and network you intend to use, at a time and under conditions resembling the broadcast. A download result does not tell you how much data the computer can send out. Nor does an Airtel plan name tell you the upload rate available at your location. The result can vary with the connection, congestion and other devices using it.
YouTube’s streaming tips say the total stream bitrate must not exceed available upload bandwidth and recommend leaving 20% room. Treat that as headroom for variation and other traffic, not as a promise that a given test result will hold all night. If family members are on video calls or uploading files, their traffic competes for capacity. Repeat the test when those devices are active if that reflects normal use.
Set OBS’s output resolution, frame rate and bitrate conservatively in relation to your measured upload. YouTube publishes encoder bitrate ranges by resolution and frame rate in its encoder settings guidance; use the current table for your intended format. Do not choose the highest available setting by default. A lower setting that fits the tested connection may be a more sensible trial than one that leaves no room for changing conditions. There is no Airtel-wide upload figure or universal quality setting to apply here.
| Choice or check | What it tells you | Practical use |
|---|---|---|
| Download test | How quickly data comes down to your device | Useful for viewing and downloads, but not a substitute for upload measurement |
| Upload test on the broadcast computer | How quickly it can send data under that test’s conditions | Compare it with the total outgoing bitrate and preserve YouTube’s recommended headroom |
| Private or unlisted test stream | Whether OBS reaches YouTube and how the stream behaves in practice | Watch the preview, picture, sound and YouTube’s stream-health indication |
| Test with normal household use | How competing traffic affects the connection | Repeat under representative conditions rather than assuming an idle test describes a busy evening |
Try the test over the actual connection arrangement you plan to use. If you are on Wi-Fi, test over that Wi-Fi. A wired Ethernet connection is an optional way to connect the computer to the router and can be worth testing if convenient; it does not ensure uninterrupted streaming. If the stream health becomes poor, first reduce competing upload traffic, then consider a lower bitrate or resolution and test again. Change one thing at a time so you can tell what helped.
Airtel’s Xstream Fiber terms page describes a fair-usage threshold of 3333 GB per billing cycle, after which speed may be reduced to up to 2 Mbps, and says Airtel may amend its fair-usage policy. This wording should not be assumed to apply identically to every plan, connection or location. Check the current terms shown for your own plan on Airtel’s Xstream Fiber terms page before a long stream; do not treat an “unlimited” description as proof that no speed or policy conditions apply.
Start the broadcast and monitor it
Once the scene and output settings are ready, start streaming in OBS. Wait for the signal to appear in YouTube Studio’s Live Control Room preview. Confirm that the video moves, the loop reaches its end and starts again, and the audio is correct. Check the stream-health message before making the event public. If the scheduled workflow requires it, press Go live in Live Control Room after the preview is ready.
Keep OBS open and the computer powered throughout the session. Disable sleep settings that would suspend the computer, and make sure the router and power arrangement are suitable for the time you plan to stream. If you rely on Wi-Fi, avoid moving the computer or router during the test and broadcast. These are ways to reduce avoidable interruptions, not guarantees against a connection or power failure.
Watch the Live Control Room during the first part of the broadcast and check it periodically during a long run. YouTube recommends testing and monitoring stream health and audio/video quality. A healthy start does not establish how the connection will behave later. If the status deteriorates, check whether another device has started a large upload, inspect OBS’s dropped-frame indicators and reduce the outgoing load if appropriate. A short test under realistic conditions is more useful than guessing from a plan label.
If the stream drops, determine whether OBS stopped sending, the computer lost access to the network, or YouTube reports a problem. Reconnect according to the message shown, verify the preview and sound again, and only then resume or start a new event as appropriate. Do not assume that a loop automatically reconnects to YouTube; repetition of a local file and reconnection of the live signal are separate matters.
When ending, end the event in Live Control Room and stop streaming in OBS. YouTube says streams under 12 hours are automatically archived. Do not rely on that statement for a broadcast that runs longer than 12 hours, or assume a longer stream will appear as one recording. If you need a copy, keep a local recording and check YouTube’s current archive guidance before planning around it.
When a local OBS loop is not the right fit
The workflow above makes sense when you can leave a computer running, manage the scene and monitor the connection. Its trade-off is that the broadcast depends on that computer and local network staying available. For a short event, that may be straightforward. For a channel that needs to run continuously, you should decide how you will notice and respond to interruptions, rather than treating the Loop checkbox as an operating plan.
If you do not want to leave your own computer running, StreamNeo removes that specific burden: upload the video once, provide the YouTube stream key, and the broadcast can run with your computer switched off, with monitoring and automatic restart if it drops. It is YouTube-only, so it does not suit a workflow that must send the same stream to other platforms. Check the current details and decide whether handing off playback is preferable to operating OBS locally.
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
What Airtel upload speed do I need for YouTube Live?
There is no single Airtel upload speed to assume from a plan name. Measure upload capacity on the computer and connection you will use, compare the stream’s total bitrate with that result, and leave the headroom YouTube recommends. Test again if normal household traffic changes the result.
Can I stream a prerecorded video on repeat?
Yes. Add the local file as an OBS Media Source and enable its Loop property. The file repeats in OBS, while the encoder sends the resulting live signal to YouTube; test the transition and audio before going public.
Does Wi-Fi prevent a 24/7 loop from working?
Not necessarily, but results depend on conditions at your location and how the network is being used. Test on the Wi-Fi connection you intend to use and monitor stream health. Ethernet is an optional alternative to test, not a guarantee of uninterrupted service.
Will YouTube archive a stream longer than 12 hours?
YouTube’s guidance says streams under 12 hours are automatically archived. Do not extend that expectation to a longer broadcast; keep a local recording if you need a copy and check YouTube’s current help guidance for the event you plan.
