If your PRISM Live Studio YouTube stream should continue after a prerecorded video ends, make sure the outgoing scene still has content to send. On PRISM Desktop, check the installed media source properties for a repeat option; if you do not see one, arrange a persistent source or scene and rehearse the hand-off.
PRISM Mobile’s Keep Session feature is different: it can preserve a YouTube live session so you can resume it later, but it does not replay a finished clip. First identify whether the problem is the video ending, the PRISM transmission stopping, or YouTube taking the live session OffAir.
Identify your PRISM version and the failure point
PRISM Desktop and PRISM Mobile handle media playback and session state differently, so begin by noting which app you are using and its installed version. The location and names of controls can change between versions. Do not assume a control described for one platform is present on the other.
Then establish what actually stopped. A local video reaching its final frame is not by itself proof that the YouTube live session has ended. Check the PRISM preview and broadcast status, then check YouTube’s live control room or the public watch page from another device. Is the live still OnAir, but showing a blank or static scene? Has the outgoing scene changed? Or does YouTube itself show that the broadcast ended?
These are different faults with different remedies. A finished media source points you towards its playback properties or a scene hand-off. A live that remains OnAir but no longer receives useful content calls for a continuity check in PRISM. A session that YouTube has ended calls for platform and transmission troubleshooting, rather than just a change to the clip.
If you are planning a long-running channel, it helps to separate the playback question from the broader operating plan. For example, the considerations in choosing a 24/7 YouTube streaming service for a regional-language channel include how the channel should continue when a computer or operator is not available. That is a separate question from whether a particular PRISM media source repeats.
What happens when a Media Source finishes
A media source is an item of content used in a scene: for example, a local video, image or audio file. PRISM’s Desktop guide to using Media Source describes adding and playing local media. It also discusses a setting called “Restart playback when source becomes active”, which affects playback when a source becomes active in Studio Mode. That wording concerns restarting playback on activation; it is not evidence that the source automatically loops when it reaches the end.
The reviewed PRISM guide does not document a loop or repeat-at-end control, and it does not specify that reaching the end of a local video automatically ends a YouTube broadcast. So avoid treating either behaviour as guaranteed. The installed build may expose source properties that differ from the guide, and what happens next can depend on the scene and other sources in your setup.
Think of the media item and the broadcast as separate parts of the chain. The clip can finish while the scene and YouTube session remain active. Conversely, the platform session can go OffAir for a reason unrelated to the clip. Your practical goal is therefore not to guess what an undocumented control does, but to arrange and test what the audience should see after the last frame.
For a channel that plays bhajans, for instance, the video might be a sequence of temple footage while a separate, persistent image and audio source provide continuity. If the footage finishes, the next visible scene should be intentional rather than an unexpected blank. This is an operational approach based on maintaining content in the outgoing scene, not a PRISM-specific looping recipe.
Check the installed Desktop source properties
On PRISM Desktop, select the scene containing the video and open the properties for that media source. Read the controls available in the installed version rather than relying on a tutorial for a different build. If a loop or repeat control is explicitly present, you can try it; do not infer its meaning from a similar-sounding restart or autoplay option.
If you find a repeat option, rehearse the source through its ending and watch what happens. Confirm that the clip starts again as expected, that audio behaves as intended, and that the scene remains the one going to YouTube. A setting that appears to affect source activation may not repeat a clip at its end, so observe the actual boundary between the final frame and the next playback.
If you cannot find a repeat control, do not spend a live broadcast testing hidden shortcuts or assume one is simply located elsewhere. Use a second persistent source or a scene that can take over when the clip is finished. Where you can schedule or trigger that change yourself, make the transition deliberate and test it in advance. The persistent-scene approach is practical continuity advice inferred from how sources contribute to an outgoing scene; it is not a feature PRISM documents as an automatic end-of-clip hand-off.
Also check the source’s activation behaviour if you switch away from it and later return. PRISM’s guide explains that in Studio Mode, unchecking “Restart playback when source becomes active” is one method for addressing media that does not autoplay. That instruction is about what happens when the source becomes active, not how the source behaves when playback completes. Change it only for the behaviour you need, then test it in your own scene.
Keep live content on the outgoing scene
A scene can contain more than the prerecorded clip. Consider what should remain on air if the clip ends: a title card, a static visual, a camera, background audio, or another source that is appropriate for your channel. The right fallback depends on the programme. A study channel might use a clock and quiet background ambience; a local news loop might use a holding slate while the next bulletin is prepared.
Make sure the audience-facing result is acceptable, not merely that some signal is being sent. A frozen frame may technically look different from an ended broadcast, but it can still confuse viewers. If you switch to a holding scene, include enough context that viewers can tell the channel is intentionally between segments. For devotional content, for instance, a clear still image and continuing audio may be preferable to silence or a desktop view.
You can also reduce dependence on an exact transition by building continuity into the programme. A finished clip can lead into a persistent scene, then back to a new clip when an operator is present. If the aim is to play several prerecorded items continuously, a playlist or a purpose-built sequence may suit the job better than manually changing scenes. The guide to streaming podcast episodes from a folder continuously is relevant when the content is a succession of episodes rather than one video that must repeat.
For an unattended channel, consider who or what will notice a bad transition. Decide how you will check the stream, what a viewer should see if the next item is not ready, and how you will stop the broadcast if the fallback itself becomes unsuitable. A persistent scene is not a guarantee against transmission or platform failure; it only addresses the content hand-off when the underlying live session continues.
Rehearse the transition before going live
Do a short rehearsal with the same scene arrangement and source properties you intend to use. If possible, use a private or otherwise non-public test destination appropriate to your account, and confirm the test will not expose material you intend to keep private. The purpose is to observe the clip ending, not to run a full overnight trial without supervision.
Watch locally in PRISM and independently on YouTube. Note the source state immediately before the last frame, what appears next, whether audio continues, and whether YouTube still reports the live as OnAir. A preview alone may not tell you what viewers receive, so use a second device or browser to check the audience-facing stream when practical.
Test the fallback as well as the happy path. Move to the intended persistent scene, confirm it is actually outgoing, then return to the clip if that is part of your workflow. If a change of scene is meant to happen automatically, verify the transition under the conditions you will use; if you cannot verify it, plan for a manual hand-off or a simpler continuous scene instead.
Keep a short record of the app version, source settings, scene order and observed result. This is especially useful if PRISM updates or you rebuild the scene later. Treat the rehearsal as evidence about your own installed setup, not as proof that every version or device behaves identically.
If your actual problem is that the connection drops rather than the video ending, investigate that separately. The distinction between encoder-side and viewer-side symptoms in this buffering troubleshooting guide can help you decide whether the fault is in what your encoder sends or what a viewer receives. A repeat setting cannot repair an unstable connection.
What Keep Session does on PRISM Mobile
PRISM Mobile’s YouTube workflow addresses the session after device streaming stops. PRISM’s guide to the ending process for YouTube streaming explains that YouTube may keep a live session OnAir after streaming from the device ends. In that situation, the app may offer “KEEP” so the creator can leave that session available, or an option to end the live session.
The separate guide to resuming YouTube streams describes keeping a session and selecting the active session later to resume. It states that the mobile resume feature described there requires a channel with more than 50 subscribers. That eligibility detail is for the described resume feature; it does not mean the feature restarts a media item or provides a way to loop a finished clip.
Use Keep Session when you want to preserve or resume an eligible YouTube session after the device transmission stops. Do not use it as a solution to a clip ending while you expect the stream to continue showing content. If your mobile programme needs more video after a clip, plan that playback separately and check what the installed app supports.
If PRISM says the stream has ended, check whether YouTube is actually OffAir before deciding the video caused it. PRISM’s Stream Has Ended troubleshooting guide lists transmission or device-processing problems, platform policy and platform time limits among possible causes, and says PRISM stops its own streaming after confirming the destination live is no longer OnAir. Follow the current official guidance for the specific error you see; do not assume a finished clip explains a platform-side end.
Make the operating choice explicit
The right fix depends on the result you want. Use this comparison to keep a playback problem separate from a session problem:
| Situation | What you want | Next step |
|---|---|---|
| Desktop clip reaches its final frame | The same clip starts again | Check whether the installed source properties explicitly offer loop or repeat, then rehearse it |
| Desktop clip finishes and should be followed by other content | Viewers see a deliberate continuation | Keep another suitable source or scene ready and test the changeover |
| Mobile device transmission stops but YouTube remains OnAir | Resume the session later | Use Keep Session only for session continuity, and check the current eligibility and workflow |
| YouTube shows the live as OffAir | Understand why the broadcast ended | Investigate the destination status, transmission and the relevant PRISM error guidance |
If you run a channel from a computer that must remain available, the playback fix may not solve the bigger operational concern. A desktop workflow depends on the device and the live session continuing as intended. For an always-on channel where you want the computer off, StreamNeo can remove the need to leave PRISM running on that computer by turning an uploaded video into a YouTube live stream, with monitoring and automatic restarts if it drops. It is YouTube-only, so it is not a replacement for a workflow that depends on PRISM’s mobile session controls or other destinations.
Whichever approach you use, decide how and when the broadcast should end. PRISM’s FAQ notes that media files such as videos, images and audio clips can be used in a live stream, but a content source is not the same as an instruction to end or keep a YouTube session. When you want the broadcast to stop, use the appropriate End or Finish control and confirm the destination status. PRISM cautions that its transmission may continue after the platform appears to have ended, so check both sides rather than assuming they change together.

FAQ
Does a finished PRISM Desktop video automatically end the YouTube stream?
The reviewed PRISM Desktop guide does not specify that a local media file reaching its end automatically ends the YouTube broadcast. Check the YouTube live status and PRISM output separately. If the session remains OnAir, focus on what the outgoing scene shows next.
Where is the PRISM Desktop loop setting?
The reviewed official media-source guide does not document a loop or repeat-at-end setting. Inspect the properties in your installed version, and do not confuse restart-on-activation behaviour with repeating at the end. If no explicit repeat control is available, prepare and rehearse a persistent scene or source.
Does Keep Session replay the video on PRISM Mobile?
No. Keep Session preserves a YouTube session for a later resume in the workflow PRISM documents; it does not say that it replays a completed video. Treat session continuity and media playback as separate tasks.
What should I check if YouTube says the live has ended?
Confirm the destination status, then consult PRISM’s current troubleshooting guidance for the error. PRISM identifies transmission or device-processing issues, policy enforcement and platform limits as possible causes. Do not assume the video finishing was the cause without checking the session state.
