Use OBS Studio on the spare PC to play a local sermon recording on repeat, then send it to a YouTube Live event. Add the file as a Media Source, enable Loop, connect OBS to YouTube with the event’s server URL and stream key, and wait for the preview before clicking Go live. Test the specific PC, network, audio and video before relying on it for a service.
Before you set up the loop
Confirm the channel can stream
Check live-stream eligibility before the service. YouTube requires a verified channel with no live-streaming restrictions in the preceding 90 days; enabling live streaming for the first time may take up to 24 hours. See YouTube’s encoder workflow and live-streaming tips.
Check the spare PC
OBS supports Windows 10 and Windows 11 and lists a DirectX 10.1-compatible GPU as a basic requirement. Meeting that baseline does not guarantee that the PC can encode your chosen resolution, frame rate and scene complexity. Run OBS’s Auto-Configuration Wizard, then test the actual machine with the sermon file. OBS documents the baseline and its performance caveat in its system requirements.
Check rights and power
Confirm that the church has permission to stream the sermon recording and every included element, such as music, images or third-party clips. Having a copy of a recording does not establish that a licence covers a livestream, archive, territory or this particular use. Check the terms with the rights holder or the church’s licensing administrator.

Plan for uninterrupted power and internet. On Windows, review screen and sleep timeouts; on a laptop, check what closing the lid does. Labels and available options vary by Windows version and device. Microsoft explains Windows power states in System power states and describes power, sleep and lid settings in Battery saving tips for Windows.
Set up a single-sermon loop in OBS
- Create a scene. Open OBS Studio and add a scene for the sermon stream.
- Add the recording. Under Sources, select + → Media Source. Choose the sermon file. OBS lists MP4 among its supported formats.
- Enable looping. In the Media Source properties, turn on Loop. The file will play again after playback completes. Adjust its size and position in the preview so the picture fits the stream canvas.
- Check the sound. Play the source and watch OBS’s audio meter. Listen for the expected sermon audio and make sure it is not unintentionally muted or distorted.
OBS documents the Media Source and its Loop option in Media Sources. For a sequence of recordings rather than one repeated file, OBS’s VLC Video source supports playlists and a loop-playlist option. VLC must be installed; 64-bit OBS requires 64-bit VLC.

Connect OBS to a YouTube Live event
- In YouTube Studio, select Create → Go live. Create a stream or choose one already scheduled.
- In the event’s Live Control Room, copy its stream server URL and stream key.
- In OBS, open the stream settings and enter the URL and key. YouTube’s encoder instructions describe this connection. Treat the key like a password: anyone who has it may be able to send a feed to your channel. If it is exposed, reset it in the Live Control Room; see Manage live stream settings.
- Start streaming in OBS. Wait for the YouTube Live Control Room preview to appear and check the picture, audio and stream health. Then select Go live in YouTube.
Choose output settings the PC and connection can sustain
For a standard SDR sermon loop using H.264 over RTMP or RTMPS, YouTube recommends constant bitrate (CBR) and a two-second keyframe interval; keyframes should not be more than four seconds apart. For 1080p at 30 fps, its encoder table lists a recommended H.264 video bitrate of 5 Mbps. These are YouTube recommendations, not a guarantee that a particular PC or internet connection will handle them reliably.
Use YouTube’s current encoder settings and bitrate guidance as a starting point. Choose a resolution and bitrate that the spare PC can encode and the connection can sustain consistently. Test upload capacity rather than assuming the connection’s advertised speed is available to the stream. YouTube recommends RTMPS for encrypted ingestion; HLS has different workflow and codec options and higher latency, and is not needed for this basic setup.

Test, run and end the stream
Test before the service
Run a private or unlisted test with the same sermon file, audio levels and settings planned for the event. Check the YouTube preview, stream health, picture framing and sound. YouTube recommends testing in advance, starting the encoder before the event to check the feed, and monitoring audio and video while live. A static recording may be less demanding than a complex camera scene, but only a test on this PC and connection can confirm that.
Keep the PC awake
Before a long stream, verify Windows sleep and power settings and confirm that the network will remain connected. If the spare machine is a laptop, check its lid action rather than assuming it will keep running when closed.
Rank #4
- Powerful Performance: Intel Core i5 Hexa Core processor for reliable multitasking and smooth computing.
- Fast & Efficient: 16GB DDR4 RAM and 250GB SSD for quick startup and performance.
- Windows 11 Pro: Modern operating system with professional-grade tools and enhanced security.
- Compact Design: Space-saving mini chassis fits neatly on or under your desk.
- Renewed Quality: Professionally tested and renewed to perform like new; may show minor cosmetic wear.
End cleanly
When the service is over, end the event in YouTube and stop the encoder in OBS. YouTube says streams under 12 hours are automatically archived; see its encoder workflow.
Common problems and fixes
- No preview in YouTube: Confirm OBS is streaming, the event is the intended one, and its server URL and stream key were copied correctly. If the key may have been exposed, reset it and update OBS.
- Live streaming is unavailable: Check channel verification and restrictions. First-time enablement may take up to 24 hours, so activate it well before the service.
- The stream stutters or drops: Retest upload capacity and reduce output demands to a level the connection and PC can sustain. Check OBS and YouTube stream health during the test; a nominal system requirement or bitrate recommendation does not guarantee performance.
- The sermon does not repeat: Open the Media Source properties and confirm Loop is enabled. For a playlist, use VLC Video and check that VLC is installed with the same architecture as OBS.
- The PC stops streaming during playback: Review Windows sleep timeouts, power settings, lid action and network continuity.
- Audio or video is blocked or claimed: Review permissions and applicable licences for the sermon and all music, images or other third-party material. YouTube setup guidance cannot determine whether a particular church’s licence covers its specific stream or archive.
