Streaming to Twitch

Twitch is the leading live streaming platform for gaming, creative content, and live events. pMix includes a built-in Twitch preset.

Getting your stream key

1. Go to Twitch Dashboard
2. Navigate to Settings → Stream
3. Copy your Primary Stream Key

Your stream key is persistent — it doesn’t change between streams unless you reset it.

Configuring pMix

1. Open Settings → Streaming
2. Select Twitch as the platform
3. Paste your stream key
4. Review the recommended settings:

Setting	Recommended value
Resolution	1920x1080
Frame rate	30 or 60 fps
Video codec	H.264
Bitrate	4500–6000 kbps
Keyframe interval	2 seconds
Audio	AAC, 128 kbps

Twitch recommends 6000 kbps maximum for most streamers. Twitch Partners may have higher limits.

Going live

1. Tap Start in pMix’s output controls
2. Your stream appears on your Twitch channel within a few seconds
3. Set your stream title, category, and tags in the Twitch Dashboard before going live

Tips

• Twitch requires H.264 — H.265 is not supported
• Keyframe interval must be 2 seconds — Twitch enforces this for transcoding
• Bitrate ceiling — Exceeding 6000 kbps may cause buffering for viewers without transcoding options
• Test with a VOD — Enable “Store past broadcasts” in Twitch settings to review your stream quality after testing
