To loop a pre-recorded video on YouTube Live with OBS, add it as a looping Media Source, select an NVENC encoder in OBS, then configure the stream to match YouTube’s recommendations for your chosen codec, resolution, and frame rate. For multiple videos, use OBS’s VLC Video source with Loop Playlist enabled. Test the complete setup before relying on it: a local OBS stream still depends on your computer, power, and internet connection, and YouTube says streams under 12 hours are automatically archived—not arbitrarily long broadcasts.
1. Confirm that OBS can use your NVIDIA GPU
NVENC is NVIDIA’s hardware video encoder. OBS documents NVENC support on Windows and Linux and lists GeForce 750 Ti and 900-series or newer hardware in its compatibility guidance; current drivers and system support still matter. That compatibility list is not a guarantee that every encoder option or codec will appear on every machine. Check the encoder choices in your installed version of OBS before building the workflow around NVENC. OBS NVENC support guidance
- Update your NVIDIA graphics driver if needed, then open OBS.
- Go to Settings > Output. If Output Mode is set to Simple, switch to Advanced so the streaming encoder controls are visible.
- In the Streaming section, open the Encoder menu and confirm an NVIDIA NVENC option is available. The exact label depends on your OBS version, GPU, and installed driver.
OBS cautions that earlier-generation hardware encoders can produce lower image quality at the same bitrate than newer encoders. If NVENC is missing, check GPU and driver compatibility first; do not assume that a setting shown in a guide exists in your installed OBS.
2. Add the video and make it loop
Loop one file with Media Source
- In the Sources panel for the scene you will stream, select + and choose Media Source.
- Name the source, then select OK.
- In the source properties, enable Local File and browse to the recording.
- Enable Loop, then select OK. Preview the scene to confirm the video plays and returns to the beginning.
OBS Media Source supports common formats including MP4, TS, MOV, FLV, MKV, AVI, GIF, and WebM. The source’s playback behavior and supported formats are documented in the OBS Media Sources guide.

Loop several files with VLC Video
- Install VLC if it is not already installed. For 64-bit OBS, OBS requires 64-bit VLC for the VLC source.
- In the scene’s Sources panel, select + and choose VLC Video.
- Add the files to the playlist in the order you want them to play.
- Leave Loop Playlist enabled (OBS documents it as enabled by default), then preview the source and check that playback moves through the list and loops back to the start.
Use Media Source for a single recording; choose VLC Video when a playlist is more practical. A playlist can make transitions between separate recordings easier to manage, but its playback still depends on the local OBS machine and files being available.
3. Match OBS output to YouTube’s stream requirements
YouTube’s current general encoder guidance supports RTMP/RTMPS ingestion with H.264, HEVC/H.265, or AV1, up to 60 fps. YouTube recommends RTMPS, CBR, progressive scan, two B-frames, and a keyframe frequency of two seconds (not exceeding four seconds). Audio may use AAC or MP3; YouTube recommends stereo AAC or MP3 at 128 Kbps for the listed general settings. For SDR, use Rec. 709. Check YouTube’s encoder settings, bitrates, and resolutions for the complete guidance applicable to your selected codec and target output.

- Open Settings > Output and select the available NVENC encoder in the Streaming section.
- Choose a codec supported by both your available NVENC encoder and YouTube’s selected ingestion protocol. Do not choose AV1 or HEVC solely because YouTube supports it; confirm OBS offers it for your GPU and setup.
- Set Rate Control to CBR, set the keyframe interval to 2 seconds, and use progressive output. Set B-frames and the remaining codec-specific options in line with YouTube’s guidance and the controls your encoder exposes.
- Set the OBS output resolution and frame rate to the target you intend to stream. The source should be able to supply that picture and motion; upscaling a lower-resolution recording does not create additional source detail.
- Choose a bitrate from YouTube’s row for the exact codec, resolution, and frame rate. Test your upload connection at that expected stream quality and leave capacity for normal network variation.
Example YouTube-recommended video bitrates
| 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’s recommended bitrate values, not guaranteed minimums for a particular connection. The appropriate value changes with codec, resolution, and frame rate; consult YouTube’s full table rather than treating these examples as universal settings.
OBS’s advanced recording guide gives different NVENC recording baselines, including Constant QP 16–23. Those are recording settings, not a general YouTube streaming prescription. Similarly, OBS’s advanced NVENC options documentation is specific to OBS 31.0; availability of options such as tuning, multipass, B-frame reference, or split encode depends on the installed OBS version, codec, and GPU. Use YouTube’s live-ingest requirements for stream output rather than copying a recording preset. OBS Advanced NVENC Options

4. Connect OBS to the YouTube live event
- In YouTube Studio, open the Live Control Room and create or select the live event you intend to use. YouTube’s encoder setup instructions describe connecting an encoder to a live event.
- Copy the event’s stream URL and stream key into OBS. Depending on the OBS version, enter them under Settings > Stream or use the account/event connection workflow shown there.
- Treat the stream key like a password: anyone with access to it may be able to send video to your channel. Do not publish it in a scene, screenshot, chat, or recording.
- Start streaming from OBS and wait for the incoming preview in YouTube’s Live Control Room. Check that the video is moving, the framing is correct, and audio is present and at a suitable level before starting the event publicly.
5. Test and monitor a long-running broadcast
Test with audio and motion representative of the actual recording, not only a static screen. YouTube recommends testing before starting a live stream and checking stream health and messages. During operation, monitor the Live Control Room for warnings and verify both picture and sound. YouTube’s live encoder guidance and live streaming tips cover testing and stream health.
- Confirm the Media Source or playlist continues playing and that the loop returns to the beginning as expected.
- Watch OBS and YouTube’s stream-health messages for dropped frames, unstable delivery, or other warnings. A local preview alone does not confirm that viewers are receiving a healthy stream.
- If the stream is important, plan and test a backup encoder failover rather than assuming OBS or YouTube will automatically restore every interruption.
- If you are recording an archive locally as a separate backup, check that the recording file is growing during the broadcast and verify that it plays after the session.
A looping source does not make the whole broadcast failure-proof: the stream depends on OBS remaining active, the computer staying powered, and the network continuing to deliver data. YouTube’s cited automatic archive guidance applies to streams under 12 hours. For a broadcast expected to exceed that duration, plan shorter events if a complete YouTube replay matters, and verify the archive you need rather than assuming one uninterrupted replay will be retained. See YouTube’s live stream archiving guidance.

Choose latency and DVR for the audience
YouTube exposes latency and DVR controls in the stream settings. Lower latency can increase playback buffering, so it is less important when viewers do not need interaction. DVR allows viewers to pause, rewind, and resume. Choose based on how viewers will use the stream, not simply because a lower-latency option is available. YouTube encoder and stream settings guidance
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.6. Troubleshoot common problems
| Symptom | Likely cause | What to check or change |
|---|---|---|
| No NVENC option in OBS | The GPU, driver, operating system, or OBS setup does not expose a supported NVENC encoder. | Confirm the NVIDIA GPU and current driver, restart OBS after driver changes, and recheck Settings > Output. Compare the GPU with OBS’s documented compatibility guidance. |
| Video stops at the end of the file | Loop is off, or the wrong source is playing. | Open the Media Source properties and enable Loop. For multiple files, check the VLC Video playlist and its Loop Playlist setting. |
| Playlist source is missing or unavailable | VLC is not installed, or its architecture does not match OBS. | Install VLC; with 64-bit OBS, use 64-bit VLC. Reopen OBS and add the VLC Video source again. |
| YouTube does not receive the stream | The event URL or stream key may be incorrect, or the event may not be selected as intended. | Recheck the URL and key in OBS against the selected Live Control Room event. Keep the key private and confirm YouTube shows an incoming preview. |
| Stream-health warnings or dropped frames | The upload connection may not sustain the chosen bitrate, or delivery may be unstable. | Test at the expected quality, compare the bitrate to YouTube’s row for the selected codec and output, leave connection headroom, and lower the target if needed. Follow the Live Control Room’s health messages. |
| Black video, no sound, or incorrect framing | The source, scene layout, audio routing, or recording itself may be wrong. | Preview the exact scene before going live; confirm the intended source is visible, audio meters respond, and the file plays with sound outside the stream workflow. |
| One long YouTube replay is missing or incomplete | The broadcast may have exceeded YouTube’s stated automatic archive duration. | Do not rely on automatic archiving for a stream longer than 12 hours. Plan shorter events or maintain and verify a separate local recording. |
7. Run the same pre-recorded stream from the cloud instead
If the goal is to keep a YouTube channel live without leaving OBS and a home computer running, StreamNeo is a cloud service for looping uploaded videos to YouTube. Upload a recording or build a playlist, add your YouTube stream key once, and go live. StreamNeo keeps the playback in the cloud, so your computer and home connection do not have to stay on; it also automatically recovers if YouTube drops the stream. It plays uploaded video, not a live camera feed, and streams to YouTube only.

8. Keep copyright and channel eligibility in view
Using a pre-recorded file as a live source does not change whether you have permission to stream it. Use recordings, music, visuals, and other material you have the rights to broadcast on YouTube, and review any applicable YouTube channel and live-stream requirements before scheduling the event. A continuous broadcast also does not by itself establish eligibility for monetization; assess the content and channel against YouTube’s current policies rather than assuming that looping makes reused material eligible.
