Its 12-hour guidance concerns automatic archiving: streams under 12 hours can be archived automatically, while streams exceeding 12 hours may not be captured at all. To loop a prerecorded video as a live stream, use an encoder that repeatedly sends the video feed to YouTube Live.
How long can a YouTube live stream last?
The research available does not establish a maximum continuous broadcast duration. Do not treat 12 hours as a confirmed cutoff for the live feed: YouTube’s guidance describes that threshold in relation to archive capture, not automatic termination of a broadcast.
If you need a copy of a long stream, plan separately for recording. YouTube warns that a stream exceeding 12 hours may not be captured as an archive, so make a local recording if you need to preserve the full broadcast.
How to loop a video on YouTube Live
YouTube’s documented route for sending video to a live stream is an encoder configured with YouTube’s Live server URL and your stream key. The encoder and video source determine how repeat playback is set up; YouTube’s instructions do not specify a particular loop configuration.

Software encoder or hardware encoder?
| Option | What to know |
|---|---|
| Software encoder | YouTube supports software encoding and says expensive equipment is not needed to get started. Check that your chosen encoder and video source support unattended repeat playback. |
| Standalone hardware encoder | An optional equipment path YouTube recommends for higher-production events. It is not a requirement for looping a video. |
Compare options by repeat-playback controls, connection reliability, upload bandwidth, local recording capability, cost, and complexity. The available YouTube guidance does not rank products or verify looping features for specific encoder models.
Prepare for a long-running stream
Leave upload bandwidth headroom: YouTube recommends 20% above the total streaming bitrate. Test before going live, inspect the Live Control Room preview, monitor audio and video, and check that your local archive recording is growing. These precautions help you distinguish problems with the live feed from problems preserving a copy.

Eligibility, rules, and copyright
YouTube says a channel must be verified and must not have had live-streaming restrictions in the previous 90 days to stream live. Live content must follow YouTube’s Community Guidelines and Terms of Service.
Use video and audio you have rights to stream. YouTube warns that a live stream receiving a copyright strike or matching another copyrighted live broadcast can lead to live-streaming restrictions. Repeating a video does not give you rights to its contents.
