To stream a recorded Sunday sermon continuously from a Windows 11 PC, load the video into an OBS Studio Media Source, enable Loop, connect OBS to a YouTube Live stream with its stream key, and keep the PC awake while OBS sends the broadcast. Looping repeats the file; it does not guarantee an uninterrupted internet connection, a stream that stays online, or an archived replay. Test the full setup before using it for a service, and plan carefully if the broadcast may run longer than 12 hours.
Before you set up OBS: confirm the channel can go live
YouTube requires the channel to be verified and not to have had live-streaming restrictions in the preceding 90 days. Enable live streaming well before the service; a channel that has not streamed before may need time before the feature is ready. Check YouTube’s live streaming tips and eligibility guidance and encoder setup instructions.
Create the YouTube Live stream and protect its key
- Open YouTube Studio. In Live Control Room, create a stream or schedule one. Follow the on-screen workflow for an encoder stream.
- Copy the connection details. YouTube provides a server or stream URL and a stream key. You can select the YouTube service in OBS, or enter the URL and key in OBS’s stream settings.
- Keep the key private. YouTube describes stream keys as “like your YouTube stream’s password and address.” Do not put it in a public post, show it on screen, or share it unnecessarily. If you think it has been exposed, reset it in YouTube Studio and replace the key saved in OBS. See YouTube’s stream settings guidance.
Loop a sermon video in OBS Studio
Use Media Source for one recording
- Open OBS Studio and choose or create the scene for the sermon.
- In the Sources panel, select + and add a Media Source.
- Choose the sermon video file on the Windows 11 PC.
- Enable Loop in the source properties, then confirm the video appears in the preview and the audio mixer responds when the clip plays.
OBS Media Source is available on Windows and accepts common formats including MP4, TS, MOV, FLV, MKV, AVI, GIF, and WebM, along with common audio formats. Check the supported source details in the OBS Media Sources guide.
Use a playlist for several recordings
If the broadcast should rotate through multiple files, use OBS’s VLC Video source and select a playlist, then enable Loop Playlist. This source requires VLC to be installed; OBS notes that 64-bit OBS requires 64-bit VLC. A single Media Source with Loop repeats one file, whereas a VLC playlist can cycle through a list of recordings.

Connect OBS to YouTube and verify the preview
- In OBS, open Settings > Stream. Select YouTube if it is available, or use the custom server option and enter the server URL and stream key from Live Control Room.
- Start sending from OBS. Before taking the stream live, check YouTube Live Control Room’s preview for the correct video and usable audio.
- Confirm that the preview continues through the end of the file and into the next loop. If using a playlist, check that playback advances as intended.
- Monitor YouTube’s stream health and the actual audience playback during a test. If you also record locally, check that the recording is being written and that the destination has enough free space.
YouTube recommends testing a stream that resembles the real broadcast and monitoring it continuously. Its current encoder guidance recommends H.264 video bitrates of 5 Mbps for 720p at 30 fps and 10 Mbps for 1080p at 30 fps. These are YouTube recommendations, not guarantees that a particular internet connection can sustain the stream. Test upload stability and leave headroom rather than setting a bitrate that consumes all available upload capacity. For an audio-led sermon, choose resolution based on the recording and viewers’ needs; higher resolution may not add useful detail. See YouTube’s encoder settings and bitrate table and streaming tips.
OBS lists Windows 11 as supported, but compatible system requirements do not guarantee successful encoding or streaming. The load depends on the encoder, resolution, frame rate, and scene complexity. OBS explains this limitation in its system requirements.
Keep the Windows 11 PC awake
Windows sleep can stop the broadcast even if OBS is configured to loop. Open Settings > System > Power & battery > Screen, sleep, & hibernate timeouts and set the plugged-in sleep timeout to cover the planned stream. Review laptop lid-close and power-button behavior as well. The screen can turn off while the computer stays awake; display timeout and sleep timeout are separate controls. Microsoft’s instructions are at Power settings in Windows 11. The appropriate timeout depends on your broadcast schedule; Microsoft does not give a stream-specific setting.
Run a realistic test and monitor the broadcast
Before a service, run a private or unlisted test as appropriate. Use the same computer, recording, OBS scene, network connection, and approximate stream duration you expect to use. Check:

- The selected sermon is the intended version and plays from beginning to end.
- Loop or Loop Playlist is enabled, and playback resumes as expected.
- Audio is audible in YouTube’s preview and audience playback; watch the OBS mixer meters while the file plays.
- The YouTube preview appears and stream health remains usable over time.
- The PC stays awake, and any local recording is being saved to the intended destination.
Keep an eye on OBS and YouTube Live Control Room during the actual broadcast. A looping source only controls playback; it cannot prevent a PC problem, power loss, internet interruption, or YouTube disconnect.
Plan for YouTube’s archive and DVR limits
YouTube says streams shorter than 12 hours can be automatically archived, but a stream exceeding 12 hours may not be captured at all. If keeping the sermon matters, make a local recording as a backup and verify that it is saving. YouTube’s guidance is in Archive live streams. An external SSD for local stream recordings can provide another destination if internal storage is insufficient; it is not required to stream and does not improve stream uptime.
Viewer DVR is a separate consideration. The Enable DVR setting lets viewers pause and rewind during a live stream, but rewind may be limited or unavailable for streams longer than 12 hours. Disabling DVR prevents viewers from seeking back during the live broadcast, even if a recording becomes available later. See YouTube’s DVR guidance.
Stop the stream deliberately
When the broadcast is finished, follow the flow shown in YouTube Live Control Room to end the stream, and stop sending from OBS as appropriate. If you need a replay, confirm that the local recording is complete and usable rather than relying only on YouTube’s automatic archive. For a broadcast that may cross the 12-hour mark, do not assume YouTube will preserve it or retain full DVR rewind.

Troubleshooting common problems
YouTube shows no signal
- Confirm OBS is actively sending and the PC has an internet connection.
- Check that OBS is using the correct YouTube service or server URL and the current stream key.
- If the key may have been exposed or is no longer valid, reset it in YouTube Studio and update OBS. See Manage live stream settings.
The sermon stops instead of repeating
Open the Media Source properties and confirm Loop is enabled. For a VLC Video playlist, check Loop Playlist and confirm VLC is installed in the same architecture as OBS (64-bit VLC for 64-bit OBS).
The preview has no audio
Confirm the selected file contains an audio track and watch the OBS audio mixer meters during playback. Then verify audio in YouTube’s preview and test audience playback before the service.
The broadcast ends when nobody touches the PC
Check the plugged-in sleep timeout under Settings > System > Power & battery > Screen, sleep, & hibernate timeouts, and review lid-close and power-button actions. Turning off the display is not the same as putting the PC to sleep.
Do these 3 things before closing this tab:
1Repair Windows errors before they cause bigger problems2Scan for outdated or missing drivers - takes under a minute3Clear out junk files and repair common Windows errorsThe stream drops or the picture stutters
Check YouTube’s stream health and the network connection, then test a bitrate the connection can sustain. YouTube’s recommended H.264 values—5 Mbps at 720p30 and 10 Mbps at 1080p30—are starting guidance, not a connection guarantee. OBS encoding load also varies with settings and scene complexity, so test the actual PC and configuration before relying on it for a service.

The replay is missing or viewers cannot rewind far back
