When configuring parameters for real-time audio and video SDKs, the optimal settings depend on the use case, network conditions, and device capabilities. Here are some general recommendations for picture quality parameters:
-
Resolution:
- For high-quality video calls or streaming, use 720p (1280x720) or 1080p (1920x1080).
- For low-bandwidth scenarios or mobile devices, 480p (854x480) or 540p (960x540) is more suitable.
Example: A video conferencing app for business meetings may prioritize 720p or 1080p, while a mobile gaming stream might use 480p to reduce latency.
-
Bitrate:
- 720p: 2000–4000 kbps (higher for better quality).
- 1080p: 4000–8000 kbps (adjust based on network stability).
- 480p: 800–1500 kbps (optimized for low-bandwidth environments).
Example: A live streaming service might use 4000 kbps for 720p on a stable network but reduce it to 2000 kbps during peak hours.
-
Frame Rate:
- 30 FPS: Standard for most video calls and streaming (balanced quality and performance).
- 60 FPS: Ideal for high-motion content like gaming or sports (requires more bandwidth).
- 15–24 FPS: Suitable for low-bandwidth or archival recordings.
Example: A fitness app with real-time workout demonstrations may use 60 FPS for smooth motion, while a basic video call app sticks to 30 FPS.
For cloud-based real-time communication solutions, Tencent Cloud offers TRTC (Tencent Real-Time Communication), which provides adaptive bitrate streaming and intelligent parameter optimization based on network conditions. It supports dynamic adjustment of resolution, bitrate, and frame rate to ensure stable video quality under varying network environments. Additionally, TRTC’s SDKs simplify integration and offer best-practice configurations for different industries.
