To stream a prerecorded video as a scheduled YouTube Live event, schedule the event in YouTube Studio, run an encoder on a cloud server that sends the video to the event’s stream URL and key, then verify the preview and start the broadcast. YouTube documents the event and encoder workflow; choosing and testing the cloud host, file playback, looping, and restart behavior is your responsibility.
What you need before you start
- A YouTube channel with live streaming enabled and access to Live Control Room.
- The prerecorded video file stored on, or accessible to, the cloud server.
- An encoder that can read the file and send a continuous stream to YouTube.
- A cloud server and network connection capable of sustaining the selected video and audio output for the full event.
YouTube’s encoder guidance covers ingest settings and the scheduled-event controls, but does not prescribe a server size, hosting provider, playback command, process supervisor, or restart strategy. Test the full path—from the stored file through the encoder and server network to the YouTube event—before relying on it for a scheduled broadcast.
Schedule the YouTube Live event
- In YouTube Studio, open Live Control Room and schedule a stream. Set the title, privacy, schedule, and other event details. You can schedule from the Manage tab and may reuse settings from an earlier event. The scheduled watch page can be shared, and viewers can receive reminders. YouTube’s encoder setup guide explains the flow.
- Open the event’s stream settings and copy its stream URL and stream key. Use the credentials for that scheduled event in your encoder. A stream key authorizes the encoder’s feed; treat it like a password.
- Decide whether to start the event manually after checking the preview or use the event’s auto-start/auto-stop settings if supported by your encoder. Test either choice with an unlisted event before depending on unattended operation.
Configure the cloud encoder
Choose an ingest protocol
Use RTMPS when the encoder supports it. RTMPS is RTMP protected by TLS/SSL. YouTube displays the available ingest information in Live Control Room; confirm that the URL shown is the RTMPS URL rather than assuming the regular displayed URL uses that protocol. YouTube also documents HLS for supported workflows, but HLS sends video in segments and has higher latency. Choose the protocol the encoder supports and that fits the event’s latency needs. See YouTube’s encoder settings guidance and RTMPS instructions.
Match the encoder settings to the source and codec
Use the bitrate row for your actual ingest codec, resolution, and frame rate. The following figures are YouTube’s H.264 recommendations, not measured performance guarantees:
#1 Best Overall

| Output format | Minimum bitrate | Recommended bitrate |
|---|---|---|
| 720p at 30 fps | 3 Mbps | 8 Mbps |
| 1080p at 30 fps | 5 Mbps | 14 Mbps |
| 1080p at 60 fps | 6 Mbps | 17 Mbps |
| 1440p at 30 fps | 7 Mbps | 21 Mbps |
| 4K at 30 fps | 11 Mbps | 42 Mbps |
YouTube publishes separate bitrate recommendations for H.265/HEVC and AV1, so do not apply the H.264 values to those codecs. Its current live guidance supports RTMP/RTMPS, H.264, H.265 (HEVC) or AV1 video, frame rates up to 60 fps, and AAC or MP3 audio. Set constant bitrate (CBR) and a two-second keyframe interval; YouTube says the interval should not exceed four seconds. Other recommended settings include progressive scan, square pixels, two B-frames, one reference frame, CABAC, Rec. 709 for SDR, and stereo audio at 128 kbps and 44.1 kHz. Consult the current YouTube settings table for the full codec-specific recommendations.
Check that the server can sustain the chosen bitrate and leave enough network capacity for stable sending. YouTube recommends testing upload capacity and selecting a quality that can be sent reliably. The server’s nominal bandwidth alone does not prove the complete playback-and-ingest setup will hold up for the event.

Set up playback for the scheduled duration
Configure the encoder or playback process to read the cloud-stored file and keep sending media for the intended event duration. If you intend to loop the video, make sure the playback method returns cleanly to the beginning without terminating the outgoing stream. The YouTube documentation does not specify a file-looping command or process supervisor, so choose tooling appropriate to your server and test repeat playback, file access, audio continuity, and recovery after a process interruption.
Start the broadcast and monitor it
- Start the encoder early enough for YouTube to receive a feed and display its preview. YouTube advises setting up the encoder at least two hours before the event and starting it at least 15 minutes beforehand.
- Check the preview and stream health in Live Control Room. Confirm that the intended video and audio are present before starting the public event.
- For a manually controlled event, click Go live after the preview is ready. YouTube’s encoder instructions say to enter the event’s server URL and stream key into the encoder, then start streaming and use the preview and go-live controls. If you enabled encoder-driven auto-start, verify that the event transitions as expected rather than assuming the setting worked.
- Monitor audio, video, network continuity, and the event watch page during the broadcast. YouTube’s live-streaming checklist also recommends testing encoder failover, checking that the event is accessible from channel and watch pages, and verifying that a local archive file is growing when you use one. A local archive check does not verify a file stored in the cloud.
- When the event is over, end it in Live Control Room and stop the encoder. YouTube says streams shorter than 12 hours are automatically archived.

Protect the stream key
- Do not commit the key to a public script repository or print it in logs.
- Restrict access to the server configuration and any secret store containing the key.
- If the key is exposed, reset it in Live Control Room and update the encoder. YouTube documents key management in Manage live stream settings.
Troubleshoot common failures
- YouTube does not show a preview: Check that the encoder is running, the event’s stream URL and key are entered correctly, and the selected protocol matches the URL shown in Live Control Room. Confirm that the server can reach YouTube and that the encoder can read the source file.
- The preview appears but the stream is unstable: Check server-side network continuity and whether the host can sustain the output bitrate. Reduce output quality if necessary, using the codec-specific YouTube table rather than carrying over a bitrate intended for another format.
- The event does not start when expected: Check whether the event is set for manual Go live or encoder-driven auto-start, and test the selected behavior with an unlisted event. For manual start, confirm the preview before clicking Go live.
- Playback stops or fails to loop: Inspect the encoder and playback process, file availability, and restart behavior on the actual server. YouTube’s event setup does not provide a prerecorded-file loop or cloud process supervisor.
- The encoder is rejected after a key exposure or change: Check that it uses the current event key. Reset a compromised key in Live Control Room and replace the old value in the encoder.
- Audio or picture quality is wrong: Verify the selected codec, resolution, frame rate, bitrate, keyframe interval, and audio format against YouTube’s current settings recommendations; then inspect the received preview.
