Internet Connectivity You may want to check that the following ports are open for traffic on your network: 80 (HTTP/HTTPS), 443 (SSL), 1935 (RTMP), 2935 (RTMPS), 3478 (STUN/Rendezvous), 5349 (STUN/Rendezvous), 5353 (mDNS for NDI sources), 5960-59xx (NDI port range, 1 port per each NDI source in use), 7272 (Remote Desktop Presenter), 49152-65535 (WebRTC Media/Rendezvous – selected at random). If you are behind a firewall, check with your streaming destination for any sites you may need to whitelist.

Best Practices

Minimum Required Upload Speed

  • It is recommended that an upload speed rate of at least double the selected video bitrate be available, especially for a total target bit-rate of 10Mbps (Megabits per second) or less, or when there are multiple outgoing streams.
  • Upload speed can be tested at a website such as
  • Additional tasks that can consume upload bandwidth on the network should also be considered when determining how much of the available upload bandwidth can be allocated towards streaming


Wirecast Rendezvous uses WebRTC technology that can be very resource intensive. For the best experience, we suggest considering the following table when choosing hardware:

  Studio (2 guests + 1 host)   Pro (7 guests + 1 host)
Bandwidth4 Add 4 Mbps Add 5+ Mbps5
Processor4 i5 quad-core6 i7 quad-core6

4Based on a single simultaneous stream of 720p30 x264 @ 4.0Mbps.
5Bandwidth per guest will scale downwards as more are added to maintain reliability.
6Minimum recommended processor with example stream4. More demanding workflows may require a more capable CPU.

ISO Recording

  • Solid State Drive or fast RAID array recommended for ISO Recording and Replay functionality.
  • Actual data rates will vary depending on quality level selected for ProRes or x264, as well as the resolution and frame rate selected.
  • Total expected data rate should be compared to available disk write speed to ensure adequate disk throughput.

Failure to ensure the available disk write speed is greater than the highest expected total data rate may result in frames being dropped from recordings (ISO, Replay, and Record-to-Disk).

See our ISO Recording Guide for more information

Hardware accelerated encoding requirements:

  • Intel Quick Sync Video encoding requires an Intel CPU with an Intel® QuickSync Video core.
    List of Intel CPUs supporting QuickSync
  • NVIDIA NVENC encoding requires an NVidia GPU with Kepler architecture or newer.
    NVIDIA only maintains a general list of supported GPUs
  • Apple Hardware Accelerated H.264 encoding requires a Mac with an integrated Intel GPU*.
    *This may change in the future, as the Apple API decides what hardware acceleration method is to be used. At the time of this writing, only Quick Sync via an Intel GPU is supported.

High frame-rate streaming (60fps):

  • High frame-rate streaming will result in increased CPU usage and require a higher bit rate (4Mbps or higher) for a quality encode.
  • Simply switching to a higher frame-rate without ensuring the CPU and bitrate are sufficient may result in a lower quality encode.

CPU Usage:

  • Consider lowering your canvas frame rate and/or streaming resolution to lower CPU usage.
  • Maintained system CPU usage greater than 60% will increase the likelihood of dropped frames.
