Objective and test method

• Objective: achieve a clean, stable YouTube stream that prioritizes intelligibility and reliability over maximal sharpness
• Method: 15-minute test at 720p30 CBR ~3,000 kbps, single scene, one webcam + one window capture, verify Stream Health and VOD

Preset ladders (pick one and only scale up after a clean test)

• Baseline: 720p30, CBR ~3,000 kbps, Keyframe 2, Profile High, AAC 128 kbps
• Mid: 1080p30, CBR ~6,000 kbps, Keyframe 2, Profile High, AAC 160 kbps
• High: 1080p60, CBR ~9,000 kbps, Keyframe 2, Profile High, AAC 160–192 kbps

Encoder choices and when to switch

• If you have NVIDIA Turing/Ampere/RTX: use NVENC (new) in OBS
• If Intel iGPU is available: try Quick Sync Video
• If neither applies: x264 at veryfast or superfast for older CPUs
• Symptoms that demand a switch: encoder overload warnings, rising render time, or persistent dropped frames

Reference: OBS system requirements

Scene design that protects frame time

• One scene for your first shows; add cuts later
• Prefer Window Capture over Display Capture when possible to reduce unexpected GPU spikes
• Use static overlays first; introduce stingers/animated filters only after stable tests
• Avoid multiple browser source instances; if needed, pre-render graphics to images or short MP4s

Audio pipeline for clarity

• Set OBS sample rate to 48 kHz; match your audio interface to 48 kHz
• Mic chain minimalism: Noise suppression (light), Compressor (2:1–3:1), Limiter (-1 dB ceiling)
• Always meter while speaking; target peaks around -6 dBFS
• Monitor through wired headphones to avoid Bluetooth delay

Network and headroom rules of thumb

• Always keep ≥30% upload headroom above chosen bitrate
• Prefer Ethernet; if Wi-Fi, use 5 GHz and sit near the AP
• Close background sync (cloud drives), auto updaters, and heavy browser tabs

YouTube Live Control Room checks you should actually watch

• Stream Health: bitrate consistent, no “insufficient bandwidth”
• Latency: keep Normal latency unless live Q&A requires Low latency
• Audio levels: confirm mono/stereo routing is correct and not clipping
• After the test, review the VOD at 1× and 1.5× speed for artifacts and A/V sync

Troubleshooting by symptom

• Choppy video, CPU OK, network OK: your render time is spiking; remove animated sources and browser overlays, lock FPS to 30
• Dropped frames (network): step bitrate down 500 kbps at a time; if still unstable, step down to 540p or 480p
• Audio pumping or distortion: lower compressor ratio, verify limiter ceiling, reduce input gain at interface

When a browser studio may be the better architecture

If your streams are panels, interviews, or tutorials and your PC struggles, a browser-based studio offloads composition/encoding to the cloud and simplifies guest onboarding. It’s a different architecture that many teams adopt to reduce local CPU/GPU risk while keeping quality consistent. See: StreamYard
