How to Loop a Video in OBS for YouTube Live

A single video can loop in OBS by adding it as a Media Source and enabling Loop in the source properties. If you need several files to play in sequence, use OBS’s VLC Video source, add the files to its playlist, and enable Loop Playlist.

OBS then sends the resulting picture and sound to YouTube Live. You still need to create or select a YouTube live event, enter its server details in OBS, and test the feed before relying on it for a long broadcast.

Choose between one clip and a playlist

Start by deciding whether your broadcast is built from one file or several. The choice determines which OBS source you add and whether VLC needs to be installed on the computer running OBS.

Your material	OBS source	Main control	What you need to check
One video file repeated	Media Source	Loop	File format, framing and audio
Several files played in order	VLC Video	Loop Playlist	VLC installation, playlist order and transitions
A longer finished programme	Media Source or VLC Video	Loop or Loop Playlist	The programme’s ending and whether the repeat feels intentional

For one clip, Media Source is the simpler route because its loop control is built into OBS. You select the file, enable the setting, and let OBS replay it when playback reaches the end. The separate Restart playback when source becomes active option has a different job: it controls what happens when the source becomes visible in the active scene.

For multiple clips, VLC Video is useful because it can play a list in sequence rather than making you create a separate source for every file. VLC must be installed for that source to appear and work. OBS states that 64-bit OBS requires 64-bit VLC, so match the VLC installation to the OBS version on your computer.

The playlist route is not automatically better. It adds another installed component and another place where playback can go wrong. If you are repeating one devotional video, ambience loop or recorded talk, use Media Source. If you are rotating several bhajans, nature clips or local news segments, VLC Video is the more suitable control.

Before adding anything, check that you have permission to use the files and any music, footage or recordings in them. A looping setup changes how content is delivered, not whether you have the rights to broadcast it. If you are republishing existing material, the guidance in turning existing YouTube uploads into a 24/7 live channel is relevant to the content decision as well as the technical one.

Set up the YouTube Live event first

You can prepare OBS before creating the event, but setting up the YouTube side first gives you the stream details that OBS needs. In YouTube Studio, open Create and then Go Live to reach the Live Control Room. From there, create a new stream or select a scheduled one.

YouTube’s current encoder instructions are in its guide to creating a YouTube live stream with an encoder. The names and positions of controls can change, so use the current Live Control Room rather than relying on an old screenshot.

If live streaming has not previously been enabled for the channel, YouTube says first-time enablement may take up to 24 hours. Do this before the planned broadcast, not when the clip is already queued in OBS. A channel that is not enabled cannot be made ready simply by changing OBS settings.

Choose whether the event is immediate or scheduled. A scheduled event gives you an opportunity to start OBS, wait for YouTube’s preview to appear, and inspect the incoming feed before selecting Go live. That extra check is useful when the broadcast is a long loop, because a mistake in the first few minutes can otherwise continue for hours.

Set the title, description, visibility and other event details in YouTube Studio. If the video contains a recorded service, news bulletin or other time-sensitive material, make the description clear about what viewers are receiving. Do not imply that a prerecorded programme is happening live if that would mislead viewers.

The event setup and the playback setup are separate. YouTube creates the destination for the broadcast; OBS provides the moving video and audio. You will connect them after the scene is working locally.

Loop one clip with Media Source

Use Media Source when one local video should repeat continuously. This is the shortest OBS workflow and does not require VLC.

1. Open OBS and select the scene that will feed YouTube.
2. In the Sources box, select Add and choose Media Source.
3. Give the source a clear name, such as main devotional loop or night ambience.
4. In the source properties, select the local video file.
5. Turn on Loop.
6. Confirm the source properties and inspect the OBS preview.

OBS documents Media Source support for common formats including MP4, MOV, MKV, AVI, FLV, TS, GIF and WebM. A supported extension does not guarantee that every file will behave identically, however. The file can still have an unusual codec, missing audio, a frame size that does not fit the scene, or a playback issue that only appears at the end.

The important distinction is between Loop and Restart playback when source becomes active. Loop tells OBS to replay the file after it finishes. Restart playback when source becomes active tells OBS to start the file from the beginning when the source becomes visible in the current scene. For a simple always-visible source, Loop is the control that creates the repeating broadcast.

Use the preview to check that the entire image fits the canvas. If the video is portrait and the scene is widescreen, you may see empty space or a cropped image. Right-click the source and use the available transform options to fit or stretch it carefully. Stretching a person’s face or a text-heavy news layout can make the broadcast harder to watch, so fit the source rather than distorting it where possible.

Listen to the audio in the OBS mixer while the video plays. Check both ordinary speech and louder passages. A devotional track may sound acceptable during a quiet introduction but clip when the music begins. A study or ambience video may appear fine while its background audio is missing entirely.

Let the file reach its ending during the test. Watch for a pause, a final frame that remains visible, a click in the audio, or a jump that is too abrupt for the material. A loop is not necessarily seamless. If the original file has a hard ending, OBS will repeat that ending each time. You may need to edit the source file or accept the join as part of the programme.

OBS also documents Show nothing when playback ends as a separate setting. That control is useful when a source should disappear after finishing. It is not needed to make a loop repeat, and enabling or disabling it does not replace the Loop setting.

If the source does not appear in the preview, check that the eye icon is enabled, that the correct scene is selected, and that the file path still exists. If you move the file to another folder later, OBS may no longer be able to open it.

Loop several files with VLC Video

Choose VLC Video when your broadcast should move through multiple files in a defined order. For example, you might place six pre-recorded local news segments in one playlist, or rotate several ambience videos overnight.

Install VLC before configuring the source. OBS relies on VLC’s libraries for this source, so VLC Video will not provide a working playlist on a computer where VLC is absent. For 64-bit OBS, OBS specifies 64-bit VLC. If you have installed a different architecture, remove the mismatch or install the matching version before troubleshooting the playlist.

Once VLC is ready:

1. Open the scene that will be sent to YouTube.
2. In Sources, select Add and choose VLC Video.
3. Add the video files to the source’s playlist.
4. Put the files in the order in which they should play.
5. Enable Loop Playlist.
6. Confirm the source and check the preview and mixer.

OBS lists Loop Playlist as enabled by default in its documented VLC source settings, but check the control yourself. A default can change in a later interface, and a saved scene may have been altered by someone else. The practical test is to let the final file finish and confirm that the first file begins again.

Use filenames that make the order obvious, such as 01-opening.mp4, 02-morning-aarti.mp4 and 03-news.mp4. Do not assume that the order in which files were selected is the order viewers should receive. Open the playlist settings and verify it visually.

Test every file, not only the first one. A playlist can contain mixed resolutions, different frame rates, missing audio tracks and incompatible encodings. One faulty item can interrupt the sequence even when the other files are fine. If a clip is intended to be silent, confirm that the silence is deliberate rather than caused by an absent audio device or unsupported track.

Check how the transition feels. VLC Video moves from one file to the next; it does not automatically turn separate clips into a seamless edit. A brief black frame or audio gap may be acceptable for a local news loop and distracting in continuous music. If transitions matter, prepare a single edited programme instead, then loop it through Media Source.

For a playlist of nature footage, compare this setup with the more focused workflow in how to loop a playlist of nature videos on YouTube Live. The same distinction applies: the playlist is a sequence of files, while the YouTube broadcast is the outgoing feed created by OBS.

Connect OBS with YouTube’s stream details

After the scene plays correctly in OBS, connect it to the YouTube event. In OBS, open Settings, then Stream. Choose YouTube as the service if it is available in the current OBS version, or use the server and key fields supplied by YouTube.

In YouTube Studio’s Live Control Room, locate the stream URL or server URL and the stream key. Enter those details in the corresponding OBS fields. The exact labels can vary between OBS versions, but the purpose is the same: the server address tells OBS where to send the feed, and the key identifies the YouTube stream receiving it.

Treat the stream key as a password. Do not place it in a screenshot, public tutorial, chat message or shared document. YouTube explains how stream settings and keys are managed in its live stream settings guidance. If the key is exposed, reset it in Live Control Room and update OBS with the new value.

Do not share the key to ask someone else to configure your channel. If another person needs to help, use the appropriate channel access arrangement rather than publishing the credential. The key should remain private even when the live event itself is public.

Save the OBS settings and start with a private or unlisted test where appropriate. For a scheduled event, start streaming from OBS and wait for YouTube’s preview. Do not select Go live until the preview shows the intended scene, the audio is present and the stream health messages are acceptable.

YouTube recommends RTMPS for encoder connections. The available service and server options in OBS depend on the version and configuration you are using, so choose the secure option offered for the YouTube connection rather than assuming every field has the same label.

Match the output to your file and connection

OBS is doing more than playing the video. It is encoding the scene and sending that encoded feed over your upload connection. A high-resolution file does not automatically mean you should choose the highest possible output settings. The right combination depends on the intended resolution, frame rate, codec, available upload capacity and the settings supported by your computer.

YouTube’s encoder settings, bitrates and resolutions guide publishes bitrate ranges for different resolutions, frame rates, codecs and stream modes. Use that current table rather than copying a universal bitrate from an old tutorial. YouTube recommends constant bitrate encoding and a two-second keyframe interval, with the interval not exceeding four seconds.

The numbers in YouTube’s table are recommendations for the platform’s ingestion settings, not a promise that a particular home connection will sustain them. Leave practical headroom in your upload capacity. If your connection is already busy with cloud backups, video calls or other users, the OBS feed may become unstable even when the encoder settings look correct.

If the computer struggles, watch OBS’s performance indicators while the clip is playing. A source can be perfectly encoded on one machine and dropped on another because of different hardware, output resolution or background workload. Close unnecessary applications during the test and avoid changing several encoder settings at once.

For a long devotional or music stream, audio consistency matters as much as image quality. Keep the mixer levels below clipping and listen for silence after a file change. For a local news loop, readable text matters more than increasing resolution beyond what the source can actually provide.

Test the feed and troubleshoot playback

Do a complete preflight with representative material. If the real channel will play a morning aarti with speech, music and several scene changes, test those elements rather than a short silent sample. If it will run ambience overnight, test the longest file and the point where the playlist returns to its beginning.

Use this order:

1. Start the selected scene in OBS and confirm the image is visible.
2. Confirm the audio meter moves only when expected and does not reach clipping.
3. Start the stream from OBS.
4. Wait for the YouTube preview in Live Control Room.
5. Check the picture, audio, stream health messages and title.
6. Let a single clip reach its end, or let the final playlist item reach the first item again.
7. Watch the feed from a separate device if possible.
8. Stop the test and note any change needed before the real event.

YouTube recommends monitoring stream health and messages while live. A preview that looks correct at the start does not prove that a playlist will continue correctly, so include a complete playback boundary in your test.

If one clip does not repeat, return to the Media Source properties and confirm Loop is enabled. Check that you are looking at the same source and scene you configured. If the source becomes hidden and visible again, check whether Restart playback when source becomes active is changing the point at which it begins.

If VLC Video is missing, install VLC and confirm that its architecture matches OBS. If the source exists but the playlist does not play, remove and re-add one known-good file, then add the other files individually. This helps identify whether the problem is the source configuration or one particular file.

If the picture freezes while OBS still shows movement, compare the OBS preview with YouTube’s preview. A local preview problem points towards the source, scene or computer. A YouTube preview problem may point towards the encoder settings or upload connection. Do not assume that restarting everything fixes the cause; note which stage fails.

If the audio is delayed, test the file itself first, then check OBS audio monitoring and source properties. For a more detailed diagnostic, see how to fix audio out of sync in an OBS prerecorded YouTube stream. Avoid adding filters or offsets until you know whether the delay is in the source file or the outgoing stream.

If the stream drops overnight, OBS must be running, the computer must remain awake, and the network must remain available. A local OBS setup gives you control, but it also leaves those responsibilities with the computer and connection. For a channel that must continue while your computer is switched off, StreamNeo removes the need to keep this playback setup running locally by turning an uploaded video into a YouTube stream and restarting it when the feed drops.

FAQ

Can OBS loop a video without VLC?

Yes. Add the file as an OBS Media Source and enable Loop in its properties. VLC is needed for the VLC Video source, which is the route for a playlist of multiple files.

Why does my VLC playlist not appear in OBS?

The VLC Video source relies on VLC being installed. Install VLC and match its architecture to OBS; OBS specifies 64-bit VLC for 64-bit OBS, then restart OBS and check the source list again.

Do I need to make the YouTube stream public before testing?

No. You can use the visibility and event options available in YouTube Studio to test before a public broadcast. Start OBS, wait for the Live Control Room preview, and check the picture, audio and stream health before selecting Go live.

What happens if my YouTube stream key is exposed?

Treat it as compromised and reset it in YouTube Live Control Room, then replace the key in OBS. Do not publish or share the key while asking for technical help.
