Best Encoding Settings for Streaming: Optimize Video & Audio Quality
Encoding settings directly impact stream quality, latency, and performance. This guide covers the best OBS encoding settings, bitrate recommendations, and hardware optimizations for Twitch, YouTube, and Kick.
Understanding Encoding: x264 vs NVENC vs AMD
OBS and other streaming software offer different encoding methods. The right choice depends on your CPU, GPU, and upload speed.
x264 (CPU-Based Encoding)
Uses your processor (CPU) to handle encoding. Recommended for high-end CPUs with strong multi-core performance.
- Best for streamers without a dedicated GPU
- Offers higher quality at lower bitrates but uses more CPU resources
- May cause lag in CPU-heavy games
NVENC (NVIDIA GPU Encoding)
Uses NVIDIA graphics cards to offload encoding, freeing up the CPU.
- Best for RTX and GTX series GPUs
- Reduces CPU usage significantly
- Newer GPUs (Turing/RTX) offer quality almost equal to x264 medium settings
AMD AMF (GPU-Based Encoding)
Uses AMD graphics cards for encoding, similar to NVENC.
- Optimized for AMD Radeon GPUs
- Lower CPU impact but may have lower quality at equivalent bitrates
- Best for Ryzen and Radeon setups
Recommended Bitrate for Streaming
Bitrate settings control how much data is sent per second. The right choice depends on your upload speed and streaming platform.
Bitrate for 1080p Streaming
Best for high-quality streams with a fast internet connection.
- Twitch 1080p 60fps - 6000 Kbps
- YouTube 1080p 60fps - 9000 Kbps
- Kick 1080p 60fps - 8000 Kbps
Bitrate for 720p Streaming
Lower bitrate for viewers with slower internet speeds.
- Twitch 720p 60fps - 4500 Kbps
- YouTube 720p 60fps - 6000 Kbps
- Kick 720p 60fps - 5000 Kbps
Best OBS Encoding Settings
These are the best settings for a smooth, high-quality stream:
- Encoder: NVENC (if available) or x264
- Rate Control: CBR (Constant Bitrate)
- Keyframe Interval: 2 seconds
- Preset: Quality (NVENC) or Medium (x264)
- Profile: High
- B-Frames: 2
Hardware Optimization for Streaming
For the best performance, optimize your hardware settings:
- Enable Game Mode (Windows) to reduce background processes
- Use NVENC or AMD AMF if available to reduce CPU load
- Close unnecessary background apps like Chrome or Discord overlays
- Monitor GPU/CPU temps to avoid overheating
Fixing Common Encoding Issues
Having stream stuttering or encoding overload? Try these fixes:
- Lower bitrate if viewers experience buffering
- Use NVENC or AMD AMF instead of CPU encoding
- Reduce output resolution from 1080p to 720p
- Check internet speed and ensure upload rate is stable
