- Recommended for 1080p 60fps: 6,000 kbps
- Recommended for 720p 60fps: 4,500–5,000 kbps
- Required keyframe interval: 2 seconds
- Audio bitrate: 160 kbps (AAC)

### YouTube Live
- Recommended for 1080p 60fps: 6,000–9,000 kbps
- Recommended for 1080p 30fps: 4,500–6,000 kbps

### Bitrate Units
- 1 Mbps = 1,000 kbps
- 1 Gbps = 1,000 Mbps = 1,000,000 kbps
- Safe streaming bitrate = ~80% of upload speed

### H.265 vs H.264
- H.265 (HEVC) uses approximately 40–50% less bitrate than H.264 at equal quality
- H.265 is NOT supported for Twitch live streaming
