The requirements differ depending on which streaming method you choose:
Uscreen Live Studio: Stream from your web browser or mobile app (iOS/Android) with fixed, optimized settings (no configuration needed)
Third-Party Tools (RTMP): Advanced streaming with full control over encoder settings
Gated Zoom Links: Host interactive Zoom meetings directly through your Uscreen platform for two-way interaction

📝 NOTE: Uscreen provides the stream key, player, and CDN delivery. Your encoding setup (streaming software settings), audio/video equipment, and internet connection are your responsibility. Our support team can help with Uscreen-side issues (event setup, stream key, player behavior), but cannot configure or troubleshoot third-party streaming software.
Encoding Settings Reference
Setting | Recommended Value | Notes |
Video Codec | H.264 (x264) | Most compatible |
Audio Codec | AAC | Standard for streaming |
Keyframe Interval | 2 seconds | Required for smooth playback |
Rate Control | CBR (Constant Bitrate) | Prevents quality fluctuations |
Audio Bitrate | 128-160 kbps | Stereo, 44.1 or 48 kHz |
Quality Presets by Resolution
Resolution | Bitrate | FPS | Use Case |
1080p (Full HD) | 4500-6000 kbps | 30 | High-quality streams, professional content |
