PRISM Live Studio documents how to play a local video file on desktop and how to organise videos in a mobile playlist. Its reviewed guidance does not confirm a repeat control or say that either workflow loops automatically, so check playback in your installed version before relying on it for a continuous broadcast.
Here, “a YouTube video” can mean a local video file that you send to YouTube through PRISM, or a YouTube URL that you want to play inside PRISM. The official instructions covered here support the local-file and playlist workflows; they do not document importing a YouTube URL as a looping source.
What PRISM documents about video playback
PRISM’s desktop guide covers adding a local file as a Media Source, then describes what to try if it does not autoplay in Studio Mode. That is guidance for starting or restarting source playback. It does not establish what happens when a video reaches its end.
On mobile, PRISM documents creating a reusable Video playlist in My Studio. You can select videos, change their order and seek within playback. The guide does not confirm whether a playlist repeats, whether the last item returns to the first, or whether an individual item can repeat.
Those distinctions matter if your aim is a live channel that runs unattended. A source that plays once, a playlist that plays through, and a playlist that repeats continuously are different behaviours. Do not infer the third from instructions that only establish the first or second. The guide to repeating a video in OBS without restarting the YouTube stream covers a different app and should not be treated as evidence about PRISM.
For the desktop workflow, use PRISM’s Media Source instructions. For the mobile workflow, consult its Media Playlist instructions. These are the primary references for the steps below; neither is a loop-specific guide.
Desktop: add a local Media Source
PRISM’s desktop guide applies to Windows and Mac and describes adding a local video in Studio Mode. The file is a source within your PRISM scene; this is not the same as pasting a YouTube watch-page URL into the app.
Open the source-add window in your Studio Mode scene and choose Media Source. Select the video file on your computer. The guide’s workflow is built around a file available locally, so make sure you know where it is saved and can select it in the file picker. If your recording is stored on removable media or in a cloud folder, check that it is accessible before setting up the scene.
Once added, the source should be visible in the Studio Mode workspace. Take a moment to confirm that the intended clip is selected and that it appears in the scene as expected. A still preview or a source entry only establishes that PRISM has a source configured; it does not prove that the video will begin, finish or repeat in the way you want during a live broadcast.
This setup is useful when you have one prepared file to show. If you need to manage several clips, the desktop instructions cited here do not describe the same reusable playlist workflow documented for mobile. Avoid assuming that controls from one platform are available in the other.
Select a file and check playback in Studio Mode
After selecting the file, check the source in Studio Mode rather than assuming that adding it means it has started. PRISM’s guide identifies a setting called Restart playback when source becomes active and an Apply action for addressing autoplay behaviour. These steps concern source playback; they do not confirm continuous repeat.
A practical check is to add the source, observe whether the clip starts, and note what happens when you activate it in the scene. If you are preparing a live broadcast, preview the actual scene and confirm that the picture and sound you expect are present. If the content includes a devotional track, a study loop or an ambience recording, check that the selected file is the intended version rather than a draft or a short test clip.
Do not use the live audience as your first test of basic playback. PRISM’s desktop YouTube guide is an index for streaming guidance, including rehearsal material, rather than a dedicated loop setup guide. You can consult the desktop YouTube streaming guide for its current streaming documentation, but it does not fill the gap around repeat behaviour.
If you want a broader way to diagnose what viewers actually see, keep the distinction between a source issue and a YouTube delivery issue in mind. The stream health warning versus actual playback problems guide can help you separate those questions; neither a healthy status indicator nor a visible source proves that PRISM will repeat a file.
If the source does not autoplay
PRISM documents two ways to address a desktop source that does not autoplay. When you add the Media Source, you can uncheck Restart playback when source becomes active before clicking OK. Alternatively, leave the option checked and click Apply in Studio Mode after adding the source. Follow the current wording shown by your installed version, as interfaces can change.
There is also a separate sequence in the guide for playing the source only in the EDIT screen: add it, click Stop Media, then click Restart Media. Keep that purpose in mind. These are playback actions for the source in PRISM, not instructions to make a live broadcast repeat after the clip ends.
Try one documented method at a time, then observe the result. If the source begins, that tells you the autoplay issue is addressed for that test. It still leaves unanswered whether it will continue after reaching the end. Record the distinction in your setup notes so that a successful start is not mistaken later for a verified overnight loop.
If the file does not start after these steps, check basic causes without changing several things at once: confirm that the correct file was selected, that it remains available at that location, and that you are testing the intended scene and mode. The PRISM guidance reviewed here does not provide a comprehensive file-format troubleshooting list or a loop-specific fix, so avoid treating guesses about formats or settings as official instructions.
Mobile: create a Video playlist in My Studio
PRISM’s mobile guide covers Android and iOS. Open My Studio, tap Playlist, choose to create a Video playlist, select the videos you want, then create the playlist. The saved playlist remains in My Studio for reuse. You can change the order and seek to positions in the videos, according to the guide.
That makes the mobile workflow useful for organising more than one video without rebuilding the selection each time. It does not, on the evidence reviewed, tell you whether playback advances through every item, what happens at the final item, or whether the list begins again. Nor does it confirm an individual-video repeat control. A saved playlist is an organisation feature; do not interpret that fact as proof of an endless queue.
If you use video or music in a mobile live stream, PRISM’s guide also describes an audio-mixing choice: while media is playing, use the round more button at the top left to turn off the microphone option so that the stream mixes only the video or music sound. This is about which audio reaches the live stream, not whether a video repeats. Test the mix before going live, especially if you intend to speak over the media.
For phone-based broadcasts, the YouTube phone streaming tips may help with the wider mobile setup. They do not substitute for checking PRISM’s playlist behaviour in your own app. PRISM also has a mobile YouTube troubleshooting index, which is useful for YouTube-related issues but does not confirm a playlist loop control.
What the guidance does not confirm about looping
The reviewed PRISM pages do not identify a desktop repeat toggle, a mobile playlist loop option, or a setting that sends playback back to the beginning automatically. They also do not say that a YouTube player’s loop setting applies to a live broadcast produced in PRISM. Do not rely on any of those behaviours unless you can verify them in your own installed version and current help material.
This is not a claim that no version can ever provide such a control. It is a limit on what these documented instructions establish. No current loop menu location, control name or version-specific behaviour was verified for this article. In particular, the words “Restart playback when source becomes active” should not be read as “repeat when playback ends”: the documented wording concerns what happens when the source becomes active.
If your goal is one video repeated all day, test that exact behaviour rather than relying on the name of a source or playlist. If your goal is a sequence of different clips, test what happens after the final item. A continuous channel also needs stable audio and a plan for what viewers see if media stops. The playlist-change troubleshooting guide is relevant to a different failure mode, but it should not be taken as proof of PRISM repeat support.
Verify playback behaviour in your installed version
Before scheduling a long broadcast, test in the PRISM version and on the device you actually intend to use. Start with the local file or mobile playlist you plan to publish. Observe initial playback, then leave the test running long enough to see what happens at the end of the file or sequence. If repeat behaviour is important and the clip ends without restarting, the workflow has not met that requirement.
Where possible, run a private or otherwise controlled rehearsal using the current YouTube and PRISM guidance. Check the scene output, sound and stream status from a viewer’s perspective as well as inside PRISM. The rehearsal should answer concrete questions: does the first item start, does it stop, what happens at the end, and can you recover if playback halts? Keep a note of the app version and the controls you actually observed, rather than relying on an old screenshot or a remembered menu label.
If you find a repeat control in your version, verify its effect rather than assuming its name tells the whole story. Test one video and then, if relevant, a multi-item playlist. Confirm whether the item restarts, whether the list returns to its first item, and whether playback continues after switching scenes or reconnecting. Do not make a promise to viewers or plan an unattended channel around a behaviour you have not observed.
For an always-on channel, the choice of workflow is therefore a practical one: use the desktop Media Source when you want to work from a local file and need the documented autoplay troubleshooting; use the mobile Video playlist when you want a saved, reorderable selection in My Studio. Neither is a confirmed continuous-repeat solution in the guidance reviewed here. If leaving a computer running through the night is the risk you are trying to avoid, StreamNeo removes that specific need by running an uploaded video as a YouTube live stream while your computer is switched off; it does not change what PRISM documents about looping.

FAQ
Does PRISM Live Studio automatically loop a desktop Media Source?
The reviewed desktop instructions explain how to add a local Media Source and address autoplay, but they do not confirm automatic repeat at the end of playback. Test your installed version before relying on a Media Source for continuous playback.
Does a mobile Video playlist repeat after the last video?
PRISM’s mobile guide documents creating, reordering and seeking in a reusable Video playlist. It does not establish that the playlist restarts after its last item, so verify the behaviour in your app.
Can I paste a YouTube video URL into PRISM and loop it?
The instructions covered here support a local file on desktop and a Video playlist on mobile. They do not document importing a YouTube watch URL as a looping source; check PRISM’s current help material for any workflow not covered by those guides.
What should I do if the desktop video does not start?
Use one of PRISM’s documented Studio Mode methods: uncheck Restart playback when source becomes active while adding the source, or leave it checked and click Apply after adding it. These steps address autoplay, not repeat playback.
