Baseline internet speeds should be at least 1.5Mbps download and 0.5Mbps upload with a consistent signal for successful recording (up) and playback (down). You can test your current speed here.
If you are running into unexpected behavior, network/IT administrators should ensure the following are available for users:
- TCP ports 80 & 443 (standard)
- TCP port 1935 (for RTMP Flash recording)
- UDP port 19302 (STUN)
- UDP port range 40000-65535 (TURN/STUN/ICE port range for WebRTC)
- Whitelist the domain *.pubnub.com
If you are recording a video comment and it takes a long time to connect (more than 5-10 seconds), or if it doesn't connect at all, network administrators should ensure that all of the ports listed above are open.
