Choosing the right bitrate is the difference between a crisp, professional stream and a pixelated mess. This guide covers the optimal bitrate settings for every major platform and resolution.
🚀 Quick Answer for 2026
Twitch: Use 6,000 Kbps (CBR) for both
1080p and 720p 60fps.
YouTube: Use 9,000 - 12,000 Kbps for 1080p 60fps (AV1/HEVC
supported).
Kick: Supports up to 8,000 Kbps for 1080p 60fps.

Twitch Bitrate Settings
| Resolution | FPS | Recommended Bitrate |
|---|---|---|
| 720p | 30 | 2,500 - 4,000 Kbps |
| 720p | 60 | 3,500 - 5,000 Kbps |
| 1080p | 30 | 4,500 - 6,000 Kbps |
| 1080p | 60 | 6,000 Kbps (max) |
⚠️ Twitch Limit
Twitch has a hard cap of 6,000 Kbps. Going higher won't improve quality and may cause buffering for viewers.

CBR vs. VBR: Which Rate Control is Best?
When setting up OBS, you'll see options like CBR, VBR, CQP, and Lossless. For streaming, there is only one correct answer:
✅ Use CBR (Constant Bitrate)
Twitch, YouTube, and Facebook Live all require CBR. This ensures your stream sends data at a consistent speed, preventing network instability. VBR (Variable Bitrate) saves data during quiet moments but spikes during action, which causes dropped frames and "stream lag" for viewers.
The Importance of Keyframe Intervals
This is the most overlooked setting. Twitch requires a Keyframe Interval of 2 seconds. If you leave this on "Auto" (0), your stream may suffer from:
- Stream delay increasing over time (viewer desync)
- Unable to play on mobile devices
- "Source Error" messages on Twitch
Fix: In OBS Output settings, set "Keyframe Interval" to 2.
Don't Forget Audio Bitrate!
Video isn't everything. Bad audio ruins streams faster than pixelated video. We recommend:
- 160 Kbps: Good baseline (Twitch Standard)
- 192 Kbps - 320 Kbps: Excellent/Audiophile (Best for YouTube)
Note: Going above 160 Kbps on Twitch is allowed but often diminishing returns for voice-only streams.
Bitrate vs. Upload Speed Reality Check
Your upload speed must be stable, not just high. A speed test might say 20 Mbps, but if it fluctuates, you will drop frames.
The "Safety Buffer" Rule: Multiply your target bitrate by 1.5. If you want to stream at 6,000 Kbps (6 Mbps), you need at least 9 Mbps consistent upload speed. This leaves room for game packets, Discord voice, and network fluctuations.
Common Bitrate Mistakes
- Setting bitrate too high: Causes buffering for viewers with slow internet.
- Using WiFi: WiFi is unstable. Always use an Ethernet cable for consistent bitrate.
- Ignoring your hardware: If your GPU is maxed out at 99% usage playing a game, NVENC has no room to work. Cap your in-game FPS to leave breathing room for OBS.
- Using CBR for recording: Use CQP (Constant Quantization Parameter) for local recordings to save space while keeping quality high.
FAQ
Is higher bitrate always better?
No. Higher bitrate only helps if your upload can handle it. Too high causes buffering for viewers and dropped frames for you.
Why does my 1080p stream look worse than 720p?
At Twitch's 6,000 Kbps cap, 1080p doesn't have enough data per pixel. 720p at 6,000 Kbps actually looks sharper than 1080p at the same bitrate.
What encoder should I use?
NVENC (NVIDIA) is best for most streamers - minimal performance impact. x264 gives better quality but uses more CPU. Use NVENC unless your GPU is weak.
