To run a 24/7 YouTube stream from a spare PC, send a looping video feed to YouTube through an encoder such as OBS, using a stream key from YouTube Studio. First confirm your channel can livestream, then choose settings the PC and internet connection can sustain, test the setup, and monitor it. Do not rely on YouTube to preserve the full broadcast: streams longer than 12 hours may not be captured in the automatic archive.
Before you start: check channel access and prepare the video
YouTube requires a verified channel with no live-streaming restrictions in the preceding 90 days. Enabling live streaming for the first time can take up to 24 hours, so do this well before your planned broadcast. See YouTube’s encoder setup instructions and live-streaming tips.
For a 24/7 stream from a spare PC, the encoder must have a source that continues playing: for example, a video file or a playlist configured to loop. Check that the source and its audio behave as intended when repeated. A stream is only as continuous as the PC, encoder, power, and network carrying it; YouTube’s guidance does not establish universal minimum PC specifications or guarantee indefinite operation.
How to set up a 24/7 YouTube stream from an old PC
- Choose an encoder. YouTube describes encoder streaming as a way to send a computer-produced feed, including overlays and external audio or video, and lists OBS among verified encoder options. YouTube says expensive equipment is not necessary to get started. Confirm that the encoder can play your source on repeat and that the PC can encode your chosen output.
- Create or select a stream in YouTube Studio. Open Live Control Room and create a stream or choose an existing one. Copy the stream URL and stream key into the corresponding fields in your encoder. YouTube’s live stream settings guide explains stream keys and key management. Treat the key like a password: anyone who obtains it may be able to send video to your stream. You can reuse a custom key and reset it if it is compromised.
- Configure the encoder output. For standard RTMP/RTMPS streaming, YouTube lists H.264, H.265 (HEVC), and AV1 video, AAC or MP3 audio, and constant bitrate (CBR). Choose only a codec supported by your encoder and source. YouTube recommends RTMPS, a two-second keyframe interval, and says the interval should not exceed four seconds. Use the official encoder settings, bitrate, and resolution guidance for the current recommendations.
- Set resolution, frame rate, and bitrate to match your system. Higher resolutions and frame rates need more encoding capacity and upload bandwidth. YouTube’s recommended H.264 bitrates include 8 Mbps for 720p at 30 fps, 14 Mbps for 1080p at 30 fps, and 17 Mbps for 1080p at 60 fps. These are platform recommendations, not guarantees that a particular computer or connection will be stable. If the old PC struggles, reduce resolution or frame rate and test again rather than assuming a preset will work.
- Leave upload headroom. Your reliable upload capacity must exceed the stream bitrate. YouTube recommends leaving 20% headroom; its streaming tips advise leaving “a bit of room (20% recommended).” A connection that barely reaches the selected bitrate may result in dropped frames or interruptions.
- Test the complete setup before going public. Start an unlisted or private test if appropriate. Use video with similar motion and audio to your intended program. Check the Live Control Room preview, stream health, picture, and sound before announcing the stream. YouTube advises setting up well in advance and checking access from channel/watch pages and mobile devices.
- Start the broadcast and keep watch on it. Once the preview and health indicators are satisfactory, start the stream in the encoder and verify that it appears in Live Control Room. For an all-day broadcast, arrange a way to check the PC, connection, and stream periodically; a test cannot guarantee that power, hardware, or internet access will remain available indefinitely.
What bitrate and settings should you use?
Use YouTube’s current table for the exact resolution, frame rate, and codec you select. These examples are YouTube’s recommended H.264 bitrates, not one-size-fits-all settings:

| Output | YouTube-recommended H.264 bitrate | Practical consideration |
|---|---|---|
| 720p at 30 fps | 8 Mbps | Requires reliable upload bandwidth above the stream bitrate, with the recommended 20% headroom. |
| 1080p at 30 fps | 14 Mbps | Use only if the PC can encode it and the upload connection has sufficient headroom. |
| 1080p at 60 fps | 17 Mbps | Requires more encoding capacity and bandwidth than lower frame-rate output. |
There is no universal spare-PC minimum established by YouTube’s cited guidance. The encoder, codec support, source material, and actual upload connection all matter. Start conservatively, then test the exact output you plan to leave running. YouTube’s encoder settings page is the reference for other resolutions and frame rates.
Will YouTube save a 24-hour live stream?
Not reliably as a complete automatic archive. YouTube says streams shorter than 12 hours can be automatically archived, but a stream that exceeds 12 hours may not be captured at all. Its archive guidance says: “If your stream exceeds 12 hours, it may not be captured at all.” If keeping the entire program matters, enable a local recording in your encoder and confirm that it is actually being saved. Storage needs depend on the recording settings and how long you keep it; do not assume the YouTube replay will be a backup.

Can you leave OBS running all day?
You can configure an encoder such as OBS to send a continuous feed, but leaving it open is not by itself a guarantee of a 24/7 broadcast. The PC must remain powered, the encoder and source must keep running, and the network must stay available. Test the actual machine and monitor the stream rather than relying on an assumed minimum specification or a single successful launch.
- Keep the source playlist or file available to the encoder and verify that looping works.
- Make sure the PC will not sleep or shut down during the broadcast, using the operating-system power settings appropriate for your machine.
- Use a reliable network connection. A wired connection may be useful if available, but YouTube does not require Ethernet for every stream.
- Plan for local recording storage if preserving the full broadcast is important.
Common problems and fixes
- Live streaming is not available yet: confirm channel verification and check for restrictions in the preceding 90 days. First-time activation may take up to 24 hours.
- YouTube receives no video: check that the stream URL and key in the encoder match the selected stream in Live Control Room. If you suspect the key has been exposed, reset it and update the encoder.
- Dropped frames or an unstable stream: reduce the output bitrate, resolution, or frame rate, then test again. Confirm that upload capacity reliably exceeds the bitrate and preserves YouTube’s recommended 20% margin.
- The old PC cannot sustain the selected output: choose a lower resolution or frame rate, and use a codec supported by the PC and encoder. The cited YouTube guidance does not benchmark codecs on an unspecified computer.
- No complete replay appears afterward: a stream exceeding 12 hours may not be captured in YouTube’s automatic archive. Use a local recording if retaining the whole broadcast is necessary.
