TikTok LIVE Agency Stream Key: OBS Setup Guide for Creators

If you have a stream key, OBS can make your LIVE look and sound professional. This technical guide documents a proven configuration, scene design for vertical screens, QA steps, and a troubleshooting tree.

Core configuration

  • Canvas/Base 1080×1920 and Output 1080×1920 at 30 fps.
  • x264 or NVENC; bitrate 4500–6000 kbps; CBR on; keyframe 2.
  • Audio 48 kHz with noise gate → compressor → limiter; target −16 LUFS.

Scene design

  1. Intro scene with countdown and rules.
  2. Main scene with camera crop, topic bar, and chat dock.
  3. CTA scene for follows, gift recap, and next stream time.

Stream key steps

  1. Receive key from agency when eligible.
  2. Paste RTMP URL + key in OBS → Settings → Stream.
  3. Run a private test to check sync, dropped frames, and CPU.

Lighting and camera

  • Three‑point lighting; avoid ring glare by raising the key light.
  • Lock exposure and white balance.
  • Keep background simple to avoid compression noise.

Troubleshooting

  • Audio delay → add 120–180 ms sync offset.
  • Crackling mic → adjust buffer size or change USB port/hub.
  • Bitrate spikes → enforce CBR and cap at ~5500 kbps.
  • High CPU → reduce filters or switch to NVENC.
