For one prerecorded video, add it to OBS as a Media Source and enable Loop. For several separate files, use an OBS VLC Video source and enable Loop Playlist; both settings repeat playback, but neither is a promise of a zero-gap transition between files.
OBS sends its scene to YouTube Live as an encoder stream. The practical answer is to choose the right playback source, configure the repeat control, then test the actual files and audio at their boundaries before you rely on the stream. If a handoff pause is unacceptable, consider making one preassembled file and testing its end-to-start join as well.
Choose one file or a playlist
Start by deciding what OBS needs to play. If your channel repeats a single bhajan recording, meditation video, study ambience track or already-edited programme, a Media Source is the direct route. If you need OBS to move through a collection of separate files, a VLC Video source provides playlist controls.
| Setup | Suited to | Main trade-off |
|---|---|---|
| Media Source with one file | One video, or a sequence already combined into one file | Few moving parts, but the file's end-to-start join still needs checking |
| VLC Video playlist | Several separate files that should play in order and repeat | Convenient list management, but no documented guarantee of gapless file handoffs; VLC is required |
| Hosted 24/7 workflow | A channel that should continue without a local encoder computer running | Less dependence on your own computer, but verify the provider's current features and terms |
For a playlist, write down the intended order before adding files. A devotional channel might rotate morning prayers, instrumental bhajans and a visual interlude; a local business might run a welcome message, product clips and opening-hours information. Confirm that the order makes sense to someone arriving halfway through, because a live viewer may not see the beginning of the cycle.
The single-file approach can reduce transitions between separate media items: the sequence has already been assembled before OBS plays it. It does not remove the need to inspect the join from the end of the file back to its beginning. A fade, silence, black frame or sudden change in loudness at that point remains part of the file's content.
If a playlist is central to the channel, see the practical considerations in this guide to scheduling a prerecorded playlist to loop on YouTube Live. The distinction here is specifically about OBS playback controls and what their documentation does—and does not—say about transitions.
Add a looping Media Source
In OBS, create or select a scene for the prerecorded output. Add a Media Source, give it a useful name, and select the local video file. In the source properties, turn on Loop. OBS describes Media Source as a way to play media files and documents the option to restart playback when the file reaches its end. The OBS Media Sources guide is the primary reference for the control and its behaviour.
Check the other source settings against your material rather than changing them by habit. For example, decide whether the source should be hidden when playback ends only if the scene relies on that behaviour; with looping enabled, the intended result is repeated playback. Preview the scene and make sure the source fills the canvas as expected. If the file includes audio, check that the OBS audio meter moves and that the sound is routed to the stream mix.
Looping one file avoids a playlist handoff between distinct files, but OBS's loop option is not a content editor. It will not repair an awkward join, remove a closing slate or make a quiet ending match a loud opening. Play through the end and restart in the OBS preview. Listen on headphones and watch the picture, including the first and last frames.
For a channel that needs to restart after a power interruption, looping addresses only the media playback part of the problem. It does not itself restart OBS or recover a dropped internet connection. Those are separate operational concerns; the power-cut recovery checklist for a 24/7 ambient stream is relevant if your local computer and connection are part of the plan.
Add a VLC Video playlist for multiple files
For multiple separate videos, add a VLC Video source to your scene. Add the files to its playlist in the order you want them to play, then check the list carefully for duplicates, missing items and filenames that are easy to confuse. Test each item in the source preview before moving on to the repeat setting.
OBS documents VLC Video as the playlist source, with controls for choosing and repeating playlist entries. It is separate from the single-file Media Source. If you have a sequence that needs to be edited often, keeping its files separate can make replacements straightforward: update a clip rather than rebuilding a long combined file. The trade-off is that playback must hand off from one file to another, and the official documentation does not say that those handoffs are gapless.
Think about file consistency before you go live. A portrait clip among landscape clips, a noticeably different loudness level, or a different frame rate can make a transition apparent even if playback proceeds as expected. OBS may display the sources, but the playlist control does not standardise how your audience perceives the sequence. Use representative files and watch the result through every type of boundary that occurs in the actual playlist.
If your audience depends on a continuous audio bed—for example, a lofi study station or a long devotional programme—listen at the boundary as well as watching it. A brief pause may be more disruptive in audio than in a sequence of visuals with deliberate breaks. Do not assume that repeated playback of the list proves that its individual transitions are suitable for your channel.
Enable Loop Playlist and install VLC if needed
Once the files are in the VLC Video playlist, enable Loop Playlist in the source properties. That tells OBS to start the playlist again after it reaches the end. It is not the same as looping an individual file, and it does not establish a seamless transition between two separate files or from the last item back to the first.
The VLC Video source depends on VLC being installed on the same computer as OBS. If the source is absent, check the prerequisite before rebuilding the scene or assuming that the setting has moved. OBS notes that a 64-bit OBS installation requires 64-bit VLC for this source. Install the suitable VLC version, then reopen OBS and check whether VLC Video is available.
A VLC playlist can be useful when you want to keep a set of clips separate and reorder them in the scene. A single Media Source can be simpler where one file contains the full programme. Neither option should be treated as an assurance of uninterrupted output: source playback, file decoding, the local computer and the connection to YouTube are different parts of the chain.
If the plan depends on OBS staying open for long periods, distinguish source looping from application recovery. OBS has separate reconnection behaviour for a stream that loses its connection; see the OBS auto-reconnect settings for an always-on playlist stream for that separate concern. Reconnection cannot make a playlist boundary gapless, just as Loop Playlist cannot restore a lost network connection.
Connect OBS to a YouTube Live event
Before configuring the encoder, confirm that your channel can go live. YouTube says live streaming must be enabled for the channel, and that first-time activation can take up to 24 hours. Its current live-streaming tips also outline channel eligibility and preparation. Check the official page for current requirements, especially if the channel has not streamed before.
Create or schedule a live event in YouTube Live Control Room and choose the encoder workflow. YouTube provides a server URL and stream key for OBS to use. In OBS, open the stream settings, select YouTube or the appropriate service configuration, and enter the event details as directed. Treat the stream key as a credential: do not show it in a screen recording or share it with people who do not need access. If you need more context on handling that credential, read how to keep a YouTube stream key secure.
Then configure output settings to suit the content and your available upload capacity. YouTube's encoder settings guidance discusses supported protocols, codecs, audio, constant bitrate encoding and keyframe intervals, and points to its current bitrate recommendations. Use the current table for the resolution and frame rate you have chosen rather than copying a setting from an unrelated tutorial. A stable, modest output that your connection can sustain is more useful than a high setting that repeatedly strains it.
Start the encoder and wait for the preview in Live Control Room before making the event public. YouTube's encoder setup instructions describe the workflow of creating an event, connecting an encoder and checking the incoming stream. A private or unlisted test is a sensible way to check the picture and audio without treating your first public broadcast as a rehearsal.
Test transitions with the actual media
Use the same files, OBS computer, scene, output settings and internet connection that you intend to use for the channel. A short test with placeholder clips may confirm that the source can play, but it will not tell you whether your real files have an awkward audio join, a black frame or a pause that matters to your viewers. Test the full playlist if practical, or at least every distinct kind of transition and the end-to-start repeat.
Watch and listen at each boundary. Look for a blank or frozen picture, a change in framing, a sudden level shift, a click or a stretch of silence. Note whether a pause is actually in the media, occurs while OBS changes files, or appears only in the YouTube viewer. The distinction matters: editing the file may fix a content join, while a connection or encoding issue calls for checking stream health and output settings.
YouTube recommends testing the stream and monitoring it while it runs. Keep Live Control Room open during a test and check its preview and stream health, while also observing the actual programme in a separate viewer where possible. A local OBS preview alone does not confirm what YouTube receives. For an always-on channel, check again after leaving the stream running long enough to encounter the repeat point rather than stopping before the first cycle ends.
If you find an unacceptable handoff, possible production choices include adjusting the edit, making a single combined file, or using deliberate transitions in the content. A combined file removes handoffs between separate playlist entries, but its own final-to-first join still needs a test. These are ways to manage the production, not promises that OBS or YouTube will provide a zero-gap result.
Also test recovery separately. A successful transition test says nothing about what happens after the computer sleeps, OBS closes, power fails or the connection drops. Conversely, an auto-reconnect setting does not establish that the media source will resume at the expected point. Write down what you observed and have someone check the channel during the first longer run.
Plan for the operating trade-off
A local OBS setup gives you direct control over scenes, sources and the playlist, and may be enough if you already have a computer that can stay powered and connected. That also makes the computer, its updates, power supply and internet connection part of the broadcast plan. For a small shop running a daily information loop, a person may be able to check the machine; a channel intended to run overnight needs a clear plan for what happens when nobody is nearby.
A hosted 24/7 workflow may suit someone who does not want to leave a home or shop computer running. YouTube's encoder help lists software and hardware encoder approaches, and its verified encoder information includes cloud-based services for prerecorded 24/7 streams. That listing is not an endorsement. Check each provider's current capabilities, terms and pricing directly, and compare whether it supports your actual files and YouTube workflow.
StreamNeo is useful when the specific pain is keeping a local computer switched on just to repeat an uploaded video on YouTube: it runs the broadcast from the cloud after you provide the file and stream key. It is YouTube-only, so it is not a fit if your distribution requirement is another platform as well. Decide based on the source format, how tightly transitions need to join, who can monitor the channel, and whether you prefer local control or a hosted workflow.
Whichever route you choose, do not treat a repeated video as a substitute for checking the channel. Confirm that the stream is actually live, inspect the sound and picture after a restart or playlist cycle, and check the current YouTube guidance when you make changes to the encoder or event. YouTube says streams under 12 hours are automatically archived; if you rely on an archive for a long-running channel, verify the current behaviour and plan around that stated limit rather than assuming one continuous archive will be kept indefinitely.

FAQ
How do I loop a prerecorded video on a YouTube livestream?
Add the file to OBS as a Media Source and enable Loop in its properties. Connect OBS to a YouTube Live event with the event's stream details, then test the file's end-to-start join before broadcasting publicly.
How can I stream a playlist on YouTube Live without a pause?
Use an OBS VLC Video source, add the files to its playlist and enable Loop Playlist to repeat the list. OBS documents repeat playback, not a guarantee of zero-gap transitions between distinct files, so test your actual media and decide whether any handoff is acceptable.
Why can’t I see VLC Video in OBS?
The source requires VLC installed on the same computer as OBS. OBS also documents that 64-bit OBS needs 64-bit VLC, so check both the installation and architecture, then reopen OBS.
Would one combined video remove the gap?
A combined file removes the handoff between separate playlist entries, which may simplify a sequence that must play in a fixed order. Its final frame and audio still meet its first frame and audio when the file loops, so test that join too; it is not a guaranteed zero-gap transition.
