To loop a local video file in Streamlabs Desktop, add it as a media source in the scene you intend to use and enable its repeat or loop setting in the source properties. That configures playback inside the scene; it does not start a YouTube livestream by itself.
The broad workflow is straightforward, but the exact dialog labels can vary by release. Streamlabs’ current guidance confirms adding sources and setting up a stream, while its technical article discusses looping media without documenting every current control. Check the installed version rather than relying on a guessed checkbox name.
Add a source to the intended scene
Start by selecting the scene that should contain the video. A scene is the composition Streamlabs sends to the preview and, once you go live, to the broadcast. If your channel has separate scenes for an opening card, the main loop and a holding screen, choose the one where this file should appear rather than adding the source to whichever scene happens to be selected.
In that scene’s Sources panel, use the plus control to add a source. Streamlabs’ getting-started guide confirms this general source-add workflow. The precise choices and sequence shown after you press the control may differ in the installed release, so treat the following as a workflow, not a promise about each dialog.
If you already have a suitable source in the scene, inspect it before adding another. Duplicate media sources can cause confusion: one may be visible while another is hidden, or more than one may be playing audio. Give the source a recognisable name if the interface offers that choice, such as “Evening bhajan video” or “Shop notice loop”. A clear name helps when you return to a scene later to change the file or diagnose sound.
Source order matters. A video can be present but covered by an image, browser panel or other full-screen source above it. Streamlabs’ quick-start guidance notes the importance of source ordering. Keep the video visible in the composition, and place overlays intentionally: a logo or clock may sit above the footage, while an opaque background usually belongs beneath it.
Select a local video media source
For a file stored on your computer, choose the local media-source route rather than a viewer-request widget. Streamlabs’ technical article describes regular media files, including video and audio formats, as media sources. The source is tied to the file you select, so you need access to that file on the computer running Streamlabs Desktop.
Do not confuse this with Streamlabs Media Share. Media Share is a separate widget intended for viewer-requested public YouTube videos; it is not the documented route for playing a local file with the local source’s loop control. Streamlabs explains the distinct feature in its Media Sharing support article. If your goal is a pre-prepared devotional programme, ambience video or shop notice, use a local media source instead of building the setup around viewer requests.
This distinction also affects what you can test. With a local file, you can preview the chosen content and its audio in the scene before going live. A viewer-request widget has its own setup and content flow; do not assume its controls or playback behaviour match those of a local media file.
Choose the video file
When the source asks for media, browse to the file you intend to use and select it. The exact file-picker sequence depends on your operating system and Streamlabs release. Check the filename and location carefully, especially if you keep several exports with similar names, such as a full-length programme and a short test render.
A file stored locally is not automatically a permanent part of the scene in the sense of being embedded in it. If you move or rename it, the saved source may no longer point to the same location. Keep the working copy in a stable folder and avoid cleaning up or reorganising that folder immediately before a long broadcast. If the source later appears blank or reports missing media, verify that the original file is still where the source expects it to be.
Use a file you have permission to broadcast. The setup steps do not establish whether a particular recording, song or image is permitted under current YouTube rules, and adding it successfully to Streamlabs does not answer that question. Check the current official guidance for your circumstances and use content you are entitled to transmit.
If the video has several audio tracks or includes sound you do not want, test it before the broadcast rather than assuming the source will select the intended track. For a file that needs preparation first, this guide to removing extra audio tracks from an MKV before streaming may help you think through that separate task. It is not required for every file, and changing a file introduces its own chance of exporting the wrong version, so keep an untouched original.
Enable looping in the source properties
Open the properties for the media source you just added and look for the control that makes playback repeat. Enable that behaviour, then confirm or apply the property changes using the controls available in your version. The official material reviewed confirms the media-source loop behaviour, but it does not establish the exact current checkbox label or its placement in every dialog. Avoid following a click-by-click instruction that assumes labels not visible in your installation.
The intent is simple: the source should reach the end of its media and begin again while the scene remains active. Verify that the repeat option belongs to this particular source, not a different source selected in the list. If you have more than one video in the scene, a setting on one source does not necessarily affect the others.
Looping changes playback behaviour, not the broadcast schedule. It does not make a scene live on YouTube, reconnect your channel, or guarantee that the file will play without interruption. It also does not turn an unsupported file or source type into a reliable loop. Use the local media source for a local file, and check the behaviour of that chosen file in the installed release.
Streamlabs’ technical article on media-file caching explains that caching can reuse decoded frames for looping media. The article reports an internal measurement of more than 35% CPU usage reduction; it was published in 2019 and last updated in 2022. That is a historical Streamlabs result, not a forecast or promise for your computer. Reusing frames has a memory cost, and the balance depends on the machine and workload. If performance is marginal, check actual resource use during a test rather than treating the figure as a guarantee.
Check the scene preview and audio
Before going live, inspect the scene preview. Confirm that the footage is visible, framed as intended and not hidden beneath another source. If it should fill the frame but appears small or cropped, correct the source’s placement or size in the scene and then inspect the preview again. A video that looks acceptable in a media player can still be obscured or poorly positioned in a layered scene.
Listen to the audio from the beginning, not just by looking at the moving image. Check whether the file’s sound is enabled and whether it reaches the expected audio controls. If the stream should be silent, make sure the source is not quietly contributing audio. If it should include music or speech, listen at a sensible level and check that another source is not duplicating it. A headphone check can catch a muted track, a second copy of the same sound or an abrupt transition before viewers encounter it.
Pay attention to the shape of the loop. Some clips have a natural ending and beginning; others show a pause, black frame or audible pop when playback restarts. A loop setting does not edit the file to remove these seams. If the join is distracting, revise the source file or select a more suitable in-and-out point before relying on it for a long session. The practical checks in this guide to loop seams, black frames and audio pops are relevant when the repeat itself works but the restart is visible or audible.
Also check the scene’s other sources. A logo, ticker or background can cover part of the video; an alert or browser source can introduce sound; and a hidden source can be mistaken for a playback failure. When diagnosing, change one thing at a time and watch the preview so you know whether the issue was visibility, file playback or audio routing.
Start the YouTube broadcast separately
Once the source is configured, you still need to start a broadcast through the normal YouTube streaming workflow. Adding a file and enabling its loop do not publish anything to your channel. Streamlabs’ getting-started and quick-start materials treat scene/source setup and going live as separate parts of the process.
Before you start, confirm that the intended scene is selected and that the correct YouTube destination and stream setup are in place. The details depend on how you have connected Streamlabs and configured your channel. Follow the current interface and YouTube’s official guidance for the account and broadcast you are using; do not infer that a visible preview means viewers can already see a live stream.
After starting, verify the broadcast from the viewing side if practical. The local preview confirms what Streamlabs is composing, while checking the live destination confirms that the broadcast has actually reached YouTube. Keep an eye on the stream state and audio at the start, particularly if you have changed scenes or files since the last test.
For a home setup, the local route has a clear trade-off: you control the scene and can use your existing file, but the computer and streaming application need to remain part of the operating setup. If your actual requirement is an unattended, long-running channel without keeping your own computer on, that is a different operating choice from configuring a local source. StreamNeo addresses that specific need by letting you upload a file once and run the YouTube broadcast with your computer switched off, so it removes the need to keep this desktop setup running for the stream. It is YouTube-only; choose based on whether you need this local scene control or an unattended cloud-run broadcast.
Test playback before relying on the loop
A short, deliberate test is more useful than assuming the setting worked. Start playback in the preview and observe it through the end of the file into its next start. Confirm that the image continues, the audio behaves as expected and the source remains visible. If the file is long, you can use a short test copy with the same relevant encoding and audio arrangement to check the restart sooner, but then test the final file as well because an export can differ.
During the test, distinguish a source issue from a YouTube issue. If the preview itself stops, investigate the local source and file. If the preview continues but the broadcast does not, check the separate go-live and connection state. If only the sound stops, look at audio configuration and the file’s own track. Keeping these symptoms separate saves time and avoids changing an unrelated setting.
For a channel that runs for many hours, consider what happens when you need to leave the desk. A local Streamlabs loop is useful when you want scene overlays, hands-on control or a file already prepared on that computer. It is not a substitute for testing the computer, power, network and application as a continuous operating setup. The bitrate guidance for 24/7 YouTube streaming on Indian broadband is relevant to the connection side, but it does not make a local media source itself more reliable.
Write down the working scene, file location and audio state once the test succeeds. That small record is useful if you later open the project and find a different scene selected or a source pointing to an old file. If you replace the video, repeat the preview and restart check; a loop that worked for one file is not proof that a different export has the same timing, framing or sound.

FAQ
Does adding a media source start my YouTube livestream?
No. Adding the source and enabling repeat playback only configures the scene in Streamlabs Desktop. You must still start the YouTube broadcast through your normal go-live flow and verify that it is live.
What is the loop setting called?
The official sources confirm the repeat behaviour but do not establish one exact current label or dialog location for every release. Open the selected media source’s properties and look for its repeat or loop control, then verify the result in the preview rather than relying on a label from an older screenshot.
Is Media Share the same as a local looping file?
No. Media Share is a separate viewer-request widget for public YouTube videos, while a local media source plays a file selected from your computer. Use the local source workflow for a prepared file you want to include in your own scene.
Why might the video repeat but still look or sound wrong?
The restart can expose a visible seam, black frame or audio pop that the loop control does not remove. Check the file’s ending and beginning, source visibility and audio, and test through a complete restart before relying on it for a longer broadcast.
