You can send a local video file to YouTube Live through Streamlabs Desktop by adding it as a media source, connecting the app to your YouTube stream, and checking the preview before you go live. The available guidance supports regular files such as MP4, but does not verify a whole-folder playlist import or automatic advancement between files.
That distinction matters if your aim is an unattended channel. Follow the supported steps below for a single file, then check the media-source controls in your installed Streamlabs version before relying on any folder workflow. Do not assume that a file which loops can also hand off automatically to the next file.
Check that your YouTube channel can stream
Before setting up Streamlabs, confirm that live streaming is available on the channel you plan to use. YouTube Help says the channel must be verified and must not have had a live-streaming restriction in the preceding 90 days. YouTube’s general live-streaming guidance also says streamers must be at least 16. Check the current YouTube eligibility guidance rather than relying on an old channel status or another creator’s experience.
If live streaming has not been enabled, resolve that first; configuring an encoder cannot bypass a restriction on the channel. If you see an eligibility problem, the guide on why live streaming may not be available on your channel may help you identify what to check next. The account and channel you use in YouTube Studio should be the ones you intend to broadcast from.
Decide whether you are creating a scheduled event or starting an unscheduled stream. A scheduled event gives you an event page and a preview-and-go-live step in Live Control Room; an unscheduled stream follows a different start flow. YouTube documents both approaches, so choose the one that fits your audience and verify the current controls shown for that stream type.
Add a regular video file as a source
Streamlabs Desktop builds a scene from sources. Streamlabs’ Quick Start Guide describes creating a scene and adding sources in the Sources panel. Its media-file guidance discusses regular files such as MP4 as sources and covers looping media. These sources support adding a video file to a scene; they do not establish the exact current steps for importing a directory as a playlist.
In practical terms, start with one video file you control and can locate on the computer running Streamlabs. Create or select the scene intended for the broadcast, then use the source controls in your installed app to add that file as media. Labels and available options may differ by version, so use the app’s visible controls and current Streamlabs documentation instead of assuming a tutorial’s exact menu names still apply.
A media source is not the same thing as a folder queue. If you add one file and the source offers a loop setting, looping that file means the same file may repeat; it does not establish that another file will start afterwards. For devotional channels, study streams or ambience, that difference can turn a seemingly complete setup into a broadcast that repeats one clip all night.
Use only video and audio you own or have permission to stream, and check the relevant rights before broadcasting. A file being saved locally, or available to watch on another site, does not by itself grant permission to retransmit it. YouTube’s own encoder instructions cover the broadcast connection, not rights clearance for the content you choose.
Confirm the media controls in your installed version
Streamlabs’ media-file article is useful evidence that ordinary media files can be used and that looping has been discussed, but it is older than its general setup guide. Treat it as background on capability, not a promise that your current desktop app has the same labels or behaviour. Open the media-source properties in the version you actually have and inspect the options it presents.
In particular, confirm what happens when the file reaches its end, whether it can loop, and whether the source offers a playlist or next-file control. The research available for this guide does not verify current click-by-click whole-folder import or automatic advancement in Streamlabs Desktop. Do not follow invented instructions to select a folder, build a queue or enable auto-advance: those may not exist in your version, and a source that repeats one file is not a substitute.
Test the behaviour with non-critical content before scheduling a public event. If you need several files to play in sequence, verify the sequence in the app and in a private or otherwise appropriate test stream before depending on it. Check that the transition from one clip to another is acceptable and that sound does not disappear or overlap unexpectedly. If the installed version offers no clear playlist control, plan around a single supported source or investigate a playback workflow whose current behaviour you can establish.
This is also where the goal affects the choice of tool. A single file that repeats may suit a short ambience loop; a channel that must move through a changing set of recordings needs dependable sequencing. The article on OBS settings for a 24/7 replay stream is relevant background for a different desktop workflow, but it should not be read as proof of Streamlabs folder controls.
Connect Streamlabs and set a sustainable output
Create a stream in YouTube Studio or select the scheduled event, then connect Streamlabs Desktop using the platform connection available in its stream settings. Streamlabs’ current general setup guide describes connecting platforms under Settings and configuring the scene and sources. Depending on the current service flow, YouTube may be connected directly or you may need to enter YouTube’s stream URL and stream key in the encoder.
YouTube identifies the URL and key as the encoder connection details. Treat the stream key like a password: do not show it in the preview, include it in a screen recording, or publish it in a message. Use the instructions for the specific YouTube event and the connection method shown by Streamlabs. If the key is exposed, replace it in YouTube Studio before relying on that event.
Output settings balance image quality against the upload capacity available where the computer is running. YouTube’s current encoder recommendations include RTMPS where supported, H.264, H.265 or AV1 video, AAC or MP3 audio, constant bitrate (CBR), up to 60 frames per second, and a two-second keyframe interval (not over four seconds). For H.264, YouTube lists 10 Mbps for 1080p30 and 17 Mbps for 1080p60. Consult its encoder settings and bitrate table when choosing your resolution and frame rate; a higher target requires more upload capacity and is not automatically better for a constrained connection.
| H.264 output example | YouTube-recommended video bitrate | What to weigh |
|---|---|---|
| 1080p at 30 fps | 10 Mbps | Lower motion demands than 60 fps, but still needs stable upload capacity |
| 1080p at 60 fps | 17 Mbps | More data to send; only choose it if the content benefits and the connection can sustain it |
These figures are YouTube’s recommendations, not guarantees of quality or a requirement to use the highest setting. A static image with music may not need the same frame rate as fast-moving footage. Keep the output consistent with the source and leave room for network variation rather than setting bitrate to the maximum your connection briefly reaches.
Test the preview before the public event
Run a test using the same type of video and audio you intend to broadcast. YouTube’s live streaming tips recommend testing with similar audio and movement, checking the Live Control Room preview, and monitoring stream health and audio/video quality. A still frame can conceal a weak connection or an audio issue that becomes obvious once the full video is playing.
YouTube recommends keeping about 20% upload bandwidth spare above the total stream bitrate. This is headroom, not a target bitrate: if your upload is inconsistent, lower the output or simplify the scene so the broadcast has margin. Check the connection at the time and place you will stream, particularly if other people share the connection or use it for video calls and uploads.
In Live Control Room, wait for the incoming stream preview and inspect it before making the event public. Check that the correct scene is visible, the video is moving as expected, and audio is present without clipping or unwanted silence. Confirm that the title and visibility setting match your intention. For a scheduled stream, YouTube’s encoder workflow includes a preview followed by a Go live action; do not assume that a connected encoder has already made the event live.
If the preview is black, frozen or silent, pause before going live. Check that the intended scene is selected, the media source points to an accessible file, and the source is not hidden or covered by another source. Then inspect the encoder connection and YouTube’s stream health indicators. Fixing a problem in preview is simpler than explaining a broken public start to viewers.
Monitor the broadcast and end the event cleanly
Once live, keep both Streamlabs Desktop and YouTube Live Control Room available. Watch for dropped connection warnings, a frozen image, missing audio or a media file that has stopped when you expected it to continue. A computer can remain open while its source is no longer behaving as intended, so a quick glance at the window is not a substitute for checking the actual incoming stream.
If the stream degrades, reduce output demands or address the network problem before changing several settings at once. Make one change, observe the preview or health indication, and note whether it helped. For a channel that runs for long periods, make a plan for someone to check it; desktop software and a local computer still depend on that computer, its power and its connection.
When the broadcast is over, end the event in YouTube Live Control Room and stop sending content from Streamlabs. For an encoder stream, stopping only the local source and leaving the event open can leave the end state unclear to viewers. YouTube says streams under 12 hours are automatically archived in Studio’s Live tab. If you need a copy or need to understand how archived broadcasts are handled, see how to save YouTube Live streams as VOD files.
If you need automatic folder playback
The evidence for this setup supports sending a regular media file through a Streamlabs source. It does not confirm that Streamlabs Desktop currently imports an entire folder as a playlist or advances to the next file automatically. If that behaviour is essential, do not treat a collection of individual media files as an unattended queue until you have verified the current controls and tested them end to end.
You have a few practical choices. Keep the broadcast to a single file if repeating it meets the brief and the installed source behaviour is clear. If you need a sequence, check Streamlabs’ current documentation or the controls in your installed version for explicit playlist and advancement support. If the feature is not documented or visible, choose a workflow whose sequencing can be tested before you promise a continuous rotation. The comparison in YouTube playlist stream versus a live encoder can help frame that broader choice, without implying that either option fits every channel.
For a genuinely hands-off broadcast, consider what must keep working overnight: the file sequence, YouTube connection, power and internet. Streamlabs Desktop running on a personal computer means the computer must stay on and the software must continue sending content. If keeping a computer awake and checking local playback is the particular pain, StreamNeo can take an uploaded video and run it as a YouTube live stream with your computer switched off; it is for YouTube, so it is not a route to other platforms. That does not remove the need to use content you have rights to stream or to confirm that the resulting broadcast suits your channel.

FAQ
Can Streamlabs play videos from a folder?
Streamlabs Desktop supports regular media files as sources, but the available evidence does not verify importing a whole folder as a playlist in the current app. Check your installed version for explicit folder, playlist and advancement controls, then test the behaviour before relying on it.
How do I loop videos on YouTube Live?
A media source may offer looping for an individual file, but looping a file means repeating that file; it does not prove that Streamlabs will advance to another clip. Confirm the current source controls in your version and test the result in preview.
How do I connect Streamlabs Desktop to YouTube Live?
Connect YouTube in Streamlabs’ stream settings if that option is available, or use the YouTube stream URL and key as required by the current encoder flow. Keep the key private, then check the incoming preview in Live Control Room before going live.
Does a local video file automatically have permission to stream?
No. Being stored on your computer does not establish that you own the relevant rights or have permission to rebroadcast the video and audio. Check the rights for each file before broadcasting.
