You can turn previously recorded videos into a continuous YouTube Live broadcast by looping a local video or playlist in OBS and sending it to YouTube with the stream URL and key from Live Control Room. The computer running OBS must stay on and connected. If you want the loop to run in the cloud instead, StreamNeo is a YouTube-only option: upload your video, add your stream key, and go live.
Before you start: check eligibility and rights
Make sure your channel can livestream
YouTube’s getting-started guidance says livestreaming requires a verified channel with no livestream restrictions in the preceding 90 days. The minimum age stated in that guidance is 16. Initial livestream activation may take up to 24 hours, so enable access before you plan to start.
Clear every part of the video for live use
Having uploaded a video before does not automatically grant permission to rebroadcast it live. Check the rights for the footage, music, images, clips, and other third-party material in every file. YouTube scans live streams for third-party matches; licensed material can still be interrupted unless the rights holder has allowlisted your channel. Looping a video does not change these obligations.
How to loop old videos with OBS
1. Prepare the video or playlist
-
For one video, open OBS and add a Media Source to the scene. Select the local video file and enable Loop so playback starts again when it finishes.

Arrange the scene as you want viewers to see it. Check that the video fills the intended frame and that its audio is present at a sensible level. If you want a title card or other on-screen elements, add them to the scene before going live.
2. Connect OBS to YouTube Live

3. Set bandwidth and monitor the feed
YouTube advises that upload bandwidth should exceed the stream bitrate, with 20% headroom. For example, if the outgoing stream uses 6 Mbps, aim for at least 7.2 Mbps of available upload capacity for that stream, not merely the connection’s advertised maximum. Other devices or uploads sharing the connection can reduce what is available.
Use the Live Control Room preview and stream health indicators to check for audio, video, and connection problems. Test the encoder and network setup before relying on a long broadcast, and keep an eye on the feed while it runs; a local loop depends on the computer, OBS, and internet connection all remaining available.
Decide how to preserve a replay
Do not assume a single 24/7 broadcast will become a complete YouTube replay. YouTube says streams under 12 hours can be automatically archived, while streams longer than 12 hours may not be captured at all. If preserving the full program matters, plan shorter broadcasts or make a separate local recording. YouTube also recommends keeping a local archive backup.

Local OBS or a cloud loop?
With OBS, you control the local scene and loop behavior, but the computer, encoder software, and connection have to stay available. YouTube’s encoder directory also lists Gyre as a cloud-based option for 24/7 prerecorded streaming. The directory listing alone does not establish current pricing, service levels, feature limits, or partner terms, so check those directly before choosing it.

The video does not repeat: For a single file, check Loop in the Media Source properties. For multiple files, check Loop Playlist in the VLC Video source and confirm VLC is installed.
-
YouTube receives no feed: Confirm OBS is using the stream URL and key for the stream currently open in Live Control Room. If you exposed the key, replace or reset it in YouTube before broadcasting again.
-
The preview buffers or stream health is poor: Check available upload bandwidth against the stream bitrate and YouTube’s 20% headroom recommendation. Reduce competing network use or adjust the encoder bitrate if the connection cannot sustain it.
-
The stream is interrupted after a content match: Review rights for all video and audio elements. A prior upload or a license does not guarantee uninterrupted live use; ask the rights holder about allowlisting where applicable.
