To save a YouTube gaming broadcast as a VOD, stream from OBS to YouTube Live and let YouTube archive the broadcast; for a dependable backup, record locally in OBS as well. YouTube can automatically archive streams shorter than 12 hours, but streams longer than 12 hours may not be captured at all. OBS’s Replay Buffer is for saving recent gameplay clips, not for replaying or archiving a YouTube broadcast.

Choose what “rerun” means for your gaming stream

A YouTube VOD is the saved archive of a completed live broadcast. YouTube can automatically archive a stream shorter than 12 hours; a broadcast that exceeds 12 hours may not be captured at all. YouTube recommends keeping a local archive as a backup. YouTube’s archive guidance explains the limit and archive controls.

OBS local recording gives you a file on your computer, independent of whether the YouTube archive is available. The Replay Buffer is different again: it saves a recent segment when you press its configured hotkey. Use it for short clips, not as a VOD rerun feature. OBS overview covers recording and Replay Buffer options.

Install OBS and confirm Linux can capture the game

OBS’s Linux installation guidance recommends Flathub for non-Ubuntu distributions. For Ubuntu 18.04 or newer, it documents installation using the OBS Project PPA and apt. The installation page was published in 2021, so check current packaging guidance for your distribution before installing: OBS Linux installation instructions.

Check that gameplay is visible and that the audio mixer meters move when the game plays and when you speak into your microphone. If a meter stays still, add or select the relevant desktop-audio or microphone source in OBS and test again before broadcasting.

Decide whether to record the full session or save short clips

For a full-session local backup

In OBS, open Settings → Output and configure recording, then choose a save location under Settings → Output or the recording options available in your version. Make a short test recording and confirm the file opens and grows while recording. Leave enough free disk space for the session; file size depends on your chosen recording settings and duration.

For recent gameplay clips

Enable Replay Buffer in OBS’s output settings, set a buffer duration that fits your available memory, and assign a save hotkey in Settings → Hotkeys. Start the buffer before play and use the hotkey to save the recent segment. A buffer only retains a recent window of gameplay; it does not create or restart a YouTube VOD.

Connect OBS to YouTube Live

YouTube requires a verified channel and no live-stream restriction during the preceding 90 days. Check eligibility and current Live Control Room labels in YouTube’s live-streaming eligibility guidance.

  1. Open YouTube Studio and enter Create → Go live to open Live Control Room. Create or schedule an encoder stream.
  2. In the stream settings, copy the server URL and stream key. YouTube describes the key as the credential that lets an encoder send your feed; treat it like a password. Do not share it, and reset it if it is exposed.
  3. In OBS, open Settings → Stream, select YouTube as the service if available, and enter the stream key. If your setup requires manual configuration, use the server URL and key provided by YouTube. Do not substitute a URL or key from another stream.
  4. Start streaming from OBS and check the Live Control Room preview and stream health before making the broadcast public or beginning gameplay. YouTube recommends setting up the encoder ahead of time and checking the preview.

For current encoder connection and key instructions, see YouTube’s encoder setup guide.

Set stream quality for stable gameplay, not just the highest number

YouTube’s general encoder guidance calls for RTMP or RTMPS, constant bitrate (CBR), and a two-second keyframe interval; do not exceed four seconds. Resolution, frame rate, bitrate, and ingestion codec should be chosen together. A higher-quality signal can look better, but it also asks more of your upload connection and computer. Use YouTube’s current recommendations for your selected resolution and frame rate rather than treating a single bitrate as universal.

In OBS, set the output mode and encoder in Settings → Output, video dimensions and frame rate in Settings → Video, and keyframe interval and bitrate in the streaming encoder options. Label placement can differ between OBS versions and output modes. Compare your chosen quality against your reliable upload capacity, then test with gameplay that has similar movement and audio to the real session. Watch OBS’s dropped frames and YouTube’s stream health during the test and broadcast. YouTube’s detailed, changeable recommendations are in Live encoder settings.

End the broadcast and find its YouTube archive

  1. Stop the stream in OBS when the broadcast is finished, then confirm the stream has ended in Live Control Room.
  2. In YouTube Studio, open Content → Live to find past broadcasts and their archive status.
  3. Open the relevant archive to change its visibility or delete it if needed. Keep the OBS local recording when you need a separate copy or when the broadcast approaches YouTube’s 12-hour archive limit.

Troubleshoot the common setup failures

  • The preview is black or the game is missing: try Display Capture or Window Capture, then verify the correct display or window is selected. OBS documents Game Capture as Windows-only, so do not depend on it in Linux.
  • There is no game or microphone audio: check the correct devices and sources in OBS’s audio settings and mixer. Test the meters and a short recording before going live.
  • YouTube does not receive the stream: confirm that the channel is verified and eligible, and that OBS has the current server URL and stream key from the intended Live Control Room stream. Reset the key if it may have been disclosed.
  • The stream buffers or drops frames: lower resolution, frame rate, or bitrate and test again. Check both OBS’s connection indicators and YouTube stream health; the sustainable setting depends on the connection and system load.
  • The VOD is missing after a long broadcast: YouTube may not capture streams exceeding 12 hours. Use a local OBS recording for sessions where a complete archive matters.
  • The recording is missing or unusable: check OBS’s configured save location, available disk space, and whether the file grows during recording. Test playback before relying on the file as your only copy.
