OBS Replay Buffer is not a continuous-streaming tool: it saves recent footage when you trigger its configured hotkey. To keep an ASMR stream running on YouTube, use an encoder connected to a YouTube live stream. For a live performance, send your microphone and other audio sources through the encoder; for prerecorded material, provide playback to the encoder. Test the whole setup and plan for YouTube’s archive and rewind limits before relying on a long broadcast.
What OBS Replay Buffer does—and what it does not do
Replay Buffer captures recent material so you can save it on demand using a configured hotkey. It does not, by itself, keep a YouTube livestream going. OBS’s overview describes enabling the buffer and setting its save hotkey in Hotkeys; YouTube’s continuous broadcast workflow instead connects an encoder to a live stream.
For a live ASMR session, the encoder sends the current microphone and other configured audio/video inputs. For a continuous prerecorded program, some playback source must feed the encoder. The official setup pages cited here do not provide a complete OBS playlist-loop recipe or establish unattended restart behavior, so verify those details for your chosen playback workflow rather than assuming Replay Buffer supplies them.
Set up a continuous YouTube encoder stream
- Create or select a live stream. In YouTube Studio, open Live Control Room and create or select the broadcast. Use the stream URL and stream key provided for that stream.
- Configure the encoder. Enter YouTube’s server URL and stream key in your encoder’s streaming settings. Keep the key private; anyone with it may be able to send video to the stream. Follow YouTube’s encoder setup guide for the current workflow.
- Choose settings your connection can sustain. YouTube’s RTMP/RTMPS guidance recommends CBR and a two-second keyframe interval, not exceeding four seconds. Choose bitrate according to the resolution and frame rate you intend to send, using the current values in YouTube’s encoder settings; there is no single appropriate bitrate for every stream. Leave about 20% upload-bandwidth headroom, as YouTube recommends.
- Feed the right material. For live ASMR, confirm the intended microphone and audio chain are selected. For prerecorded programming, configure a playback or playlist source that actually supplies the material to the encoder. Do not treat Replay Buffer as that source.
- Start the encoder and inspect the preview. Start sending to YouTube before the public event begins. In Live Control Room, confirm the incoming preview and check that picture and sound are present before going live.
- Run a representative test and monitor it. Test with audio and movement like the real session. For ASMR, include quiet passages and transitions so you can catch noise, clipping, dropped audio, or changes in level that a loud test might hide. YouTube advises continuous monitoring of audio/video quality and testing before the event; also check that any local recording you intend to keep is being written and growing.
Choose the stream format around the result you need
“Continuous” can mean keeping one public broadcast online, preserving separate recordings, or allowing viewers to rewind. Those are different outcomes, and YouTube’s duration limits matter when planning a long session.

| Viewer or creator goal | What to plan for |
|---|---|
| One uninterrupted public broadcast | Keep the encoder and its input running, monitor stream health, and have a recovery plan for interruptions. The official pages cited here do not establish that a particular OBS playback setup will restart itself after a failure. |
| Automatic YouTube archive | YouTube says streams under 12 hours are automatically archived. Do not assume a longer continuous broadcast will produce a complete usable archive. |
| Viewer rewind (DVR) | YouTube warns that DVR may be limited or unavailable on very long streams, particularly beyond 12 hours. Check the DVR guidance against the broadcast you plan. |
If your broadcast needs an archive, consider ending and starting sessions in a schedule that keeps each stream under 12 hours, then verify the resulting recordings in Studio. This is a planning approach, not a guarantee that every stream will be available in every account or circumstance.
RTMP or HLS: do not switch protocols just to fix continuity
YouTube documents both RTMP/RTMPS guidance and HLS for supported cases. HLS is not automatically a lower-latency or more reliable substitute: YouTube says it has higher latency than RTMP because it sends video in segments. Its HLS setup specifies 1–4 second segments, TS format, and a rolling playlist. See YouTube’s HLS setup guide before choosing it. HLS’s segment requirements do not, on their own, solve a failed encoder, unstable connection, or playback source that has stopped.

Troubleshoot a stream that will not stay continuous
- YouTube receives no video: Check that the encoder is running, the stream URL and key match the selected Live Control Room stream, and the encoder is sending to that destination. Recheck the preview before going live.
- The preview has video but no ASMR audio: Confirm the intended microphone/input is selected in the encoder and that its meter responds during a test. Listen to the actual stream, including quiet passages and transitions, rather than relying only on the local monitor.
- Video or audio breaks up: Compare the selected bitrate and output settings with YouTube’s current guidance for your resolution and frame rate. Make sure the connection has roughly 20% upload headroom and test under representative conditions.
- A prerecorded program stops advancing: Check the playback or playlist source that feeds the encoder. Replay Buffer saves recent content; it does not provide a looping playlist or guarantee that a source restarts.
- The stream ends after an interruption: Check whether the encoder, computer, network, or input source stopped. The YouTube pages cited here explain encoder connection and monitoring, but do not promise automatic recovery for a particular local setup. Test your recovery procedure before depending on it.
- There is no complete archive or rewind: Check stream duration and the YouTube archive/DVR limits before treating a long broadcast as a permanent recording or rewindable program.
Or let it run in the cloud
For prerecorded ASMR that should stay live on YouTube, StreamNeo is a cloud option: upload your recording or build a playlist, add your YouTube stream key, and go live.
