Best OBS Settings for Twitch: 1080p at 30 fps

Best OBS settings for Twitch at 1080p 30 fps
4,500 kbps
CBR, 30 fps, 1920×1080 output, 2-second keyframes, 160 kbps audio. You need about 6 Mbps of steady upload speed.

At 30 fps, 1080p needs less bitrate than 60 fps; 4,500 to 6,000 kbps is plenty for talking, art and slower games.

Encoder by graphics card

Your hardwareEncoderPreset

Apple silicon MacApple VT H264 Hardware EncoderDefault preset
No GPU encoder (CPU)x264Preset: veryfast (faster if it drops frames)

Hardware encoders barely touch game performance. Only use x264 if you have no supported GPU or a spare high-core CPU.

Upload speed you need

Upload ≈ (video 4,500 + audio 160 kbps) × 1.3 headroom ≈ 6.1 Mbps

Run a speed test while nothing else is uploading. If OBS shows dropped frames (red square in the corner), lower the bitrate by 1,000 kbps at a time or step down a resolution.

Frequently asked questions

What bitrate should I use for Twitch 1080p 30 fps?

4,500 kbps with CBR, plus 160 kbps audio. At 30 fps, 1080p needs less bitrate than 60 fps; 4,500 to 6,000 kbps is plenty for talking, art and slower games..

What is the best encoder for streaming to Twitch?

Your graphics card's hardware encoder: NVENC on NVIDIA, AMF on AMD, QuickSync on Intel, or the Apple VT encoder on a Mac. Use x264 only without one.
