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1Repair Windows errors before they cause bigger problems2Scan for outdated or missing drivers - takes under a minute3Clear out junk files and repair common Windows errorsTo loop a pre-recorded video on YouTube Live with OBS, add it as a Media Source, enable Loop, select an available NVIDIA NVENC encoder in OBS, then connect your YouTube Live Control Room stream URL and key. For several videos, use OBS’s VLC Video source with Loop Playlist enabled. This can run continuously only while the computer, OBS, and internet connection keep working; plan to monitor the stream rather than assume uninterrupted uptime.
1. Check that OBS can use NVENC
NVENC is NVIDIA’s hardware video encoder. OBS documents support on Windows and Linux, and its compatibility guide lists GeForce 750 Ti and 900-series or newer hardware. The actual encoder choices depend on the GPU, driver, operating system, and OBS installation, so confirm availability before building your setup around it. OBS also cautions that older hardware encoders can produce lower image quality at the same bitrate. OBS hardware encoding compatibility

- Update the NVIDIA graphics driver using the appropriate NVIDIA driver for your system.
- Open OBS and go to Settings > Output. If Output Mode is set to Simple, switch it to Advanced to see the encoder controls.
- In the Streaming encoder menu, check for an NVIDIA NVENC option. Choose an option offered by your installed OBS version and GPU; do not assume every NVIDIA card supports every codec.
If no NVENC option appears, check the driver and GPU compatibility, then restart OBS. You can use another encoder available in OBS, but this guide’s NVENC-specific settings will not apply.
2. Add a video and make it loop
For one video
- In the OBS scene where you want the stream, click Sources > + > Media Source.
- Name the source, then choose Browse beside the local file field and select your video.
- Enable Loop. Leave Restart playback when source becomes active enabled if you want playback to restart when the scene is activated.
- Confirm the source appears in the preview and that its audio is audible in the OBS mixer.
OBS Media Source supports common formats including MP4, TS, MOV, FLV, MKV, AVI, GIF, and WebM. Compatibility can still depend on the file’s encoding and the media components on your system. OBS Media Sources

For a playlist of videos
- Install VLC, matching its architecture to OBS: 64-bit OBS requires 64-bit VLC.
- In Sources, select + > VLC Video Source, name the source, and add the files in the desired order.
- Keep Loop Playlist enabled. OBS enables it by default, but verify the setting.
- Check that each item plays and that audio levels are suitable before going live.
VLC Video supports multiple media items and needs VLC installed. A single Media Source is simpler when you only need one file to repeat. OBS VLC Video Source
3. Set OBS’s stream encoder for YouTube
Open Settings > Output > Streaming and choose the available NVENC encoder. YouTube’s general live-encoder guidance lists H.264, HEVC/H.265, and AV1 for RTMP/RTMPS ingestion; what you can select depends on your GPU and OBS version. YouTube recommends RTMPS, CBR, progressive scan, two B-frames, and a keyframe interval of two seconds, not exceeding four seconds. Follow YouTube’s full settings table for your chosen codec, resolution, and frame rate rather than treating one bitrate as universal. YouTube live encoder settings, bitrates, and resolutions

- WINDFORCE cooling system
Choose codec, resolution, and bitrate together
Use the resolution and frame rate your source, GPU, and upload connection can sustain. YouTube’s listed recommended bitrates include:
| Output target | AV1 or HEVC/H.265 | H.264 |
|---|---|---|
| 1080p at 30 fps | 10 Mbps | 14 Mbps |
| 1080p at 60 fps | 12 Mbps | 17 Mbps |
These are YouTube recommendations, not guaranteed minimums for a particular internet connection. Run an upload speed test and leave capacity beyond the video bitrate for audio and network variation. Test at the same output quality you plan to use. If your chosen codec or frame rate differs, use the corresponding YouTube table row.

Use streaming settings, not recording presets
For YouTube streaming, use the platform’s streaming guidance: CBR and a two-second keyframe interval are the key baseline settings. OBS’s advanced NVENC recording guide lists recording values such as Constant QP 16–23, preset P5, and two-pass multipass; those are recording baselines, not a replacement for YouTube’s live-output recommendations. Avoid copying advanced NVENC options unless your OBS version, codec, and GPU support them. OBS advanced recording settings guide OBS Advanced NVENC Options (OBS 31.0)
4. Connect OBS to the YouTube live event
- In YouTube Studio, open Create > Go live to enter Live Control Room, then create or select the event.
- In the stream settings, copy the YouTube stream URL and stream key. YouTube may offer a reusable key; make sure it belongs to the intended event and settings.
- In OBS, open Settings > Stream, select YouTube as the service, and enter or connect the server and stream key as prompted. If using a custom RTMPS setup, enter the server URL YouTube provides.
- Apply the settings, then start streaming from OBS when ready. Check the Live Control Room preview and confirm that both moving video and audio arrive before starting or sharing the event.
A stream key grants encoder access to the stream. Treat it like a password: do not publish it, include it in screenshots, or share it in public support posts. YouTube’s setup steps and stream controls are documented in YouTube Live Control Room stream settings and YouTube encoder setup.

5. Test and monitor the stream
Before relying on a long broadcast, test with audio and motion representative of the actual video. Check the OBS preview and audio meters, YouTube’s incoming preview, stream health, and any warnings or messages. During operation, keep an eye on both OBS and Live Control Room; a local loop does not ensure that the encoder or internet connection will remain available. YouTube recommends testing before starting and monitoring stream health. YouTube live encoder guidance YouTube live streaming tips
- If you need a local recording as a backup, configure and test OBS recording separately; check that the file continues growing and verify that it plays correctly afterward.
- If stream continuity is important, prepare and test backup encoder failover rather than assuming a single computer is fail-safe.
- YouTube says streams under 12 hours are automatically archived. Its guidance does not establish automatic archiving for streams lasting 12 hours or longer. If a single complete replay matters, plan shorter event segments and verify your archive needs. YouTube live stream archiving
YouTube’s stream settings also include latency and DVR controls. Lower latency can increase playback buffering; when viewers do not need to interact in real time, lower latency may be less important. DVR lets viewers pause, rewind, and resume. Choose these based on how viewers will use the stream. YouTube stream settings

6. Keep the content eligible and safe to stream
Looping a file technically does not establish that you have the right to broadcast it or that it complies with YouTube’s policies. Use material you own or are authorized to stream, including music, artwork, and any third-party footage. Repeated playback does not change the rights status of a recording. Check YouTube’s current copyright and monetization rules for your channel and content before scheduling a long broadcast; do not assume a stream or its replay will remain available simply because OBS is sending it.
7. Troubleshoot common failures
| Symptom | Likely cause | What to check or do |
|---|---|---|
| No NVENC choice in OBS | Unsupported GPU generation, driver issue, or OBS cannot see the encoder. | Check the GPU against OBS’s compatibility guidance, update the NVIDIA driver, restart OBS, and inspect Settings > Output again. |
| Video stops after one play | Loop is off or the wrong source is being used. | Open Media Source properties and enable Loop; for multiple files, verify Loop Playlist in VLC Video. |
| VLC Video source is missing or fails | VLC is absent or its architecture does not match OBS. | Install VLC; use 64-bit VLC with 64-bit OBS, then restart OBS. |
| YouTube receives no video or audio | Wrong server/key, inactive source, muted audio, or encoder not yet connected. | Recheck the event’s stream URL and key, OBS source visibility and mixer meters, then inspect the Live Control Room preview. |
| Stream health warns or playback buffers | Upload capacity may not sustain the selected bitrate, or the connection may vary. | Run an upload test, compare usable capacity with the selected YouTube recommendation, reduce the target resolution/frame rate or bitrate using YouTube’s table, and test again. |
| Unexpected encoder errors or dropped frames | The selected codec or output load may exceed what the GPU/system can handle. | Choose a codec actually offered by NVENC on your system, lower the output target if needed, and test with the intended scene and playback running. |
| Replay is incomplete or absent after a very long broadcast | YouTube documents automatic archiving for streams under 12 hours only. | Do not assume a longer broadcast will be archived as one complete replay; use shorter event segments if that archive is necessary. |
