To stream a recorded church sermon to YouTube from a Synology NAS, use the NAS as file storage and a separate computer running OBS as the playback and encoding station. OBS reads the sermon recording from a share the computer can access, then sends it to a scheduled YouTube Live event using the event’s stream URL and key.
That produces a live broadcast of prerecorded material, not a normal video upload. Your NAS is not the encoder in this workflow, and Synology’s documented Surveillance Station broadcast feature is for live camera streams rather than playing stored sermon files.
Choose the NAS’s role in the workflow
Think of the setup as three separate jobs: the NAS holds the finished recording, the OBS computer plays and encodes it, and YouTube receives the live feed. Keeping those jobs distinct makes troubleshooting easier. If the picture is missing in OBS, check file access or the scene; if YouTube has no preview, check the connection from OBS and the scheduled event.
A Synology NAS is useful as a shared place to keep sermon masters and approved streaming copies. It can make a file available to the computer on your church network, but the fact that a video is stored on a NAS does not mean the NAS is encoding or broadcasting it. In this approach, OBS runs on a computer with access to the share, and that computer must remain on and able to send data to the internet for the duration of the event.
Synology’s Surveillance Station documentation describes Live Broadcast using a selected camera and stream profile. It does not document choosing a sermon recording stored on the NAS and playing it as the broadcast source. Do not assume a camera-broadcast feature will turn a recording library into a playback encoder. Synology describes Surveillance Station as video-management software, but that broader description is not a compatibility guarantee for your NAS model, DSM version or a prerecorded-video workflow.
For a single service or occasional rerun, an attended computer with OBS may be a sensible fit. You can see the playback, confirm that the service has begun, and stop it when appropriate. If you need an unattended channel to run continuously, the computer, application, network connection and power all become part of the operating plan. The guide to starting a 24/7 YouTube livestream channel covers the broader distinction between a one-time stream and a continuous channel.
Make sermon files available to the OBS computer
First confirm that the recording is complete and that the computer running OBS can open it from the NAS share. This is a practical network-file workflow, not a model-specific Synology-to-OBS recipe: the exact steps for sharing and access depend on your NAS configuration, computer operating system and church network.
Use the share and permissions your administrator has set up. From the OBS computer, browse to the sermon and play it in an ordinary media player before building the stream. Check the beginning and end, confirm that the audio is present, and make sure the copy is the approved recording rather than a camera original or an unfinished export. If playback from the share stutters locally, investigate that before sending the file to YouTube; a live broadcast cannot correct a file or network-read problem.
You can also copy a prepared streaming copy to the OBS computer if that better suits your network or if you want fewer dependencies during the service. The trade-off is that you now need to keep the local copy in sync with the NAS master. Whichever route you choose, test the same file and path that you intend to use on the day. Renaming or moving a file after you have selected it in OBS can leave the source pointing to a location it can no longer find.
A video that plays in one desktop player is not automatically proven to work in every OBS setup. Check the recording in OBS itself, including its audio, and leave time to resolve any codec or playback issue. Keep a written note of the share or local path, file name and which recording is approved, especially if more than one person prepares the stream.
Add a sermon as an OBS Media Source
In OBS, create or select a scene for the service, add a Media Source, and choose the sermon file accessible from the computer. OBS’s Media Sources guide explains how to add a local video file and includes the option to restart playback when the file ends. The NAS share is simply the location from which the OBS computer reads the file; OBS is still doing the playback.
Give the source a clear name, such as “Sunday sermon recording”, rather than leaving several sources with indistinguishable default names. If you have already added a source for a previous service, verify its selected file instead of assuming it points to the current recording. Use OBS’s preview to check that the image appears, then listen through the computer’s monitoring path or another reliable check so you know the correct audio source is active.
Decide whether the recording should play once or repeat. For a single scheduled sermon, repeating the file is usually not appropriate unless you deliberately want the programme to begin again if it reaches the end while the event is still live. For a continuous loop, enable the Media Source’s loop behaviour and test what happens at the end: does playback restart as intended, and is there an unwanted pause or visible transition? Do not treat a loop setting as a substitute for deciding when the YouTube event itself should end.
If the sermon is made up of separate recordings, a playlist may be more manageable than adding many individual sources and changing them by hand. OBS documents its VLC Video source for playlist playback and looping; VLC must be installed, and the OBS documentation notes that 64-bit OBS requires 64-bit VLC. A single Media Source is simpler for one file. A playlist adds flexibility, but it introduces another dependency and another place where the sequence can be wrong.
Build a scene that fits the video
A scene controls what the audience sees; it does not change the original sermon file. Add the Media Source to the scene and adjust it to fit the OBS canvas. Check whether the recording is landscape or portrait and whether the canvas shape matches the video. If the shapes differ, decide whether to preserve the full image with unused space around it or fill the frame while cropping some edges. Avoid cropping captions, a speaker’s face or any information the congregation needs to read.
Review the scene at the same resolution and aspect ratio you intend to use for the event. Watch the preview for black bars, cut-off text, stretched faces or an image that appears too small. If the sermon already contains slides, lower thirds or a church logo, inspect them at the size they will appear on a phone as well as on a desktop display. If you add a separate logo or title card, keep it legible and ensure it does not cover the recording’s own content.
Pay attention to audio as carefully as picture. Confirm that the Media Source’s audio is reaching the OBS output and that it is not accidentally muted. A common operational mistake is to see moving video in the preview and assume the programme is ready, only to discover that the audience receives silence. Listen to a representative section, including speech at a normal level, and check the beginning where a recording may have room tone or a pause before the sermon starts.
You might use a separate opening scene for a holding slide, then switch to the sermon scene when you are ready. That is useful when someone is operating OBS live, but it also means the operator must make the change deliberately. If the event is meant to be a straight replay, a single well-prepared scene reduces the number of actions to get wrong. The OBS-based Malayalam stream setup offers another example of thinking through OBS as the control point for prerecorded programming.
Choose whether to loop a file or playlist
Match the playback method to the actual programme. A single sermon intended to play once can use one Media Source without looping. If you need to repeat one recording, use its loop option. If the programme contains several recordings in a defined order, use a playlist source and enable playlist looping only if the sequence should start again after the last item.
| Programme | OBS approach | What to verify |
|---|---|---|
| One sermon, played once | One Media Source, loop off | Playback reaches the intended ending; the event is stopped when appropriate |
| One sermon repeated | One Media Source, loop on | The ending transitions back to the start as intended |
| Several recordings in sequence | VLC Video playlist source | VLC is installed and compatible with OBS; order and file paths are correct |
| Continuous rotation of recordings | Playlist with looping configured | Every item plays, the list restarts as intended, and the content sequence remains appropriate |
The table describes playback choices, not a promise that the stream will continue without interruption. For example, a playlist can move between files while OBS and the computer remain active, but it cannot recover a computer that has shut down or a network connection that has failed. If the service is a one-off, an operator can watch progress and handle the ending. If your plan is an unattended continuous channel, the recorded IELTS lesson stream guide may help you think through the additional operational choices involved in running prerecorded content for longer periods.
Before going live, check the playlist order by playing through each item or reviewing it in a controlled test. Confirm that each file is available from the computer under the account that will run OBS. A path that works while an administrator is logged in may not work after a restart or when another user account operates the computer. Keep the playlist focused on the intended service rather than relying on a last-minute manual selection.
Connect OBS to the scheduled YouTube Live event
Create and schedule the live event in YouTube Studio or the Live Control Room for the correct channel and time. YouTube’s live encoder instructions describe connecting an encoder with the stream URL and stream key supplied by YouTube. In OBS, select the YouTube service or enter the connection details as directed, then provide the URL and key for that specific event.
Treat the stream key as a credential. It authorises an encoder to send a signal to the stream, so do not publish it in a church notice, share it in an open chat, or include it in a screenshot. If several volunteers help, share access through an appropriate private method and replace the key if it has been exposed. Check that the OBS connection details belong to the scheduled event you are about to use; a remembered key may point somewhere else or be a persistent key with different behaviour.
A scheduled event and an encoder connection are separate parts of the process. Starting OBS sends the programme feed, but YouTube’s scheduled-event workflow may also require you to use the Live Control Room to start the event for viewers. Follow the current controls and prompts shown for your account. Assign a volunteer to watch the Live Control Room rather than assuming that a connected encoder alone has made the event publicly live.
The stream is a live programme even though the underlying sermon was recorded earlier. Viewers arrive at the point currently being broadcast, rather than choosing a position in a normal uploaded video. If someone needs an on-demand sermon they can start, pause and revisit, publish a separate video upload as well. Do not treat the live event as a substitute for that library item or assume its archive will have the same presentation and accessibility choices as a prepared upload.
Test playback and distinguish live streaming from uploading
Run a short private or unlisted test before announcing the service. This is prudent operating practice, not a guarantee of approval or performance. Start the OBS feed, open the event in the Live Control Room, and confirm that a preview appears. Check picture, spoken audio, framing, the start point and any intended repeat behaviour. Let the test run long enough to see that playback continues, and inspect the end or loop transition if that matters to the programme.
If the preview is absent, troubleshoot in order: confirm the correct event is open; check that OBS is connected with that event’s stream URL and key; verify that the OBS computer can still read the selected file; then inspect the active scene and source. If the preview has picture but no sound, look at the Media Source audio and OBS’s output monitoring. If the image is cropped or letterboxed unexpectedly, adjust the source and canvas before the public event rather than trying to fix it while viewers are waiting.
Also rehearse the human handoff. Decide who starts OBS, who checks the Live Control Room and who ends the event. For a one-time sermon, agree whether the operator should stop the stream at the recording’s end, leave a holding slide, or follow another service plan. Then stop sending from OBS and end the stream in the Live Control Room as appropriate. YouTube says streams shorter than 12 hours are automatically archived, but an archive is not the same workflow as uploading a normal video. Check YouTube’s current guidance for the event and archive behaviour you need.
A normal upload is a video item published to the channel’s library; viewers can choose when to play it. A live event is a real-time broadcast session carrying an encoder feed, even when that feed consists of prerecorded material. You may choose to do both: stream the service recording as a scheduled event for people joining at that time, then make a separate upload for people who need on-demand access. The guide to configuring a YouTube live loop is relevant when comparing looping as a live-channel format with a single scheduled replay.
Keep the operating plan proportionate
For a scheduled sermon, an OBS computer is an understandable choice when you have someone to prepare the scene, start the encoder and monitor the event. Its main trade-off is that the computer and its operator are part of the broadcast chain. Keep the computer powered, prevent disruptive updates or sleep during the event, and check the church’s available upload connection. These are local operational checks, not guarantees about how YouTube will handle a particular stream.
If the intended channel must continue while your own computer is off, you need a different operating arrangement from this NAS-plus-OBS workflow. YouTube’s documentation lists a cloud-based service for 24/7 prerecorded-video streams; compare any such service against your requirements and verify current details directly. StreamNeo removes the need to keep the church computer playing the recording by taking an uploaded video and sending it to YouTube as a continuing live stream, which addresses that specific computer-attendance burden rather than changing how the NAS stores the master file.
Keep an untouched master of the sermon on the NAS and use a clearly identified streaming copy if you make edits for broadcast. Record the selected file, scene, loop choice and event details in a short handover note. That small record helps the next volunteer avoid guessing which recording was tested or whether it was meant to repeat.

FAQ
Can I play a sermon video from my Synology NAS in a YouTube livestream?
Yes, if the computer running OBS can read the sermon file from the NAS share. Add that file as an OBS Media Source and send the OBS output to a scheduled YouTube Live event. In this workflow the NAS stores the recording; OBS on the computer handles playback and encoding.
Does a YouTube Live event make the sermon a normal upload?
No. A live event broadcasts the encoder’s feed to viewers who join while it is live, even if the programme is prerecorded. A normal upload is a separate video item that viewers can choose to watch on demand. You can use both formats if your audience needs both.
Can Synology Surveillance Station broadcast a stored sermon recording directly?
The cited Synology Live Broadcast instructions describe selecting a camera and stream profile, not playing a sermon file from NAS storage. They do not establish a direct prerecorded-file workflow for your NAS model. Use a computer running OBS for the approach described here, and check Synology’s current documentation for your own configuration.
Should I loop one sermon or use a playlist?
Use one Media Source for a single sermon, with looping enabled only if you intend it to restart. For several recordings in order, OBS’s VLC Video source can use a playlist, provided compatible VLC is installed. Test the order and ending behaviour before the scheduled event.
