My support expired on my perpetual (lifetime) Wirecast license, how can I renew?

We are no longer selling support renewals for perpetual/lifetime licenses. You can stay on your last supported version, purchase a new Subscription to regain access to updates and support, or use our self-help resources.

How to lower CPU usage

System CPU usage should remain below 70% while streaming.

  • Disable “Live GPU Accelerated Icons”
  • Set canvas size to 1280×720
  • Select a lower resolution encoding preset
Why am I getting dropped frames?

We recommend checking your bandwidth via speedtest.net. System CPU usage should remain below 60% while streaming. Try switching to MPEG4 if using H.264.

  • Chroma Key: Supports Green and Blue screen. Use main, fill, and back lights for best results.
  • USB Webcams: Supported via AVFoundation (Mac) and DirectShow (Win).
  • PTZ Cameras: Visca over IP control supported (e.g. PTZOptics).

Detailed Technical Specifications & System Scaling

*Review Wirecast release notes to ensure version / OS compatibility.

Supported Operating Systems

macOS Compatibility macOS Sequoia 15 or macOS 26 Tahoe.
Windows Compatibility Windows 10 (version 1809 or higher), Windows 11 (21H2, 24H2 natively supported).

Hardware Capability Baseline

Minimum Baseline
Processor (CPU): Intel® 6th Generation or newer CPU – or AMD Ryzen™ 1000 Series or newer CPU; Apple M1 or newer. Note: May be insufficient for 1080p+ or 60 fps workflows.
Memory (RAM): 8 GB of standard RAM.
Graphics Engine (GPU): Intel HD Graphics, 2 GB video memory, DirectX 11 capable; Apple Silicon: 8 GB of unified memory. Note: Insufficient for advanced Multi-Viewer workflows.
Storage / Hard Drive: 7200 RPM Hard Drive (HDD) required for local record-to-disk pipelines.
Recommended (Pro) Optimal Target
Processor (CPU): Intel® 7th Generation or newer CPU – or AMD Ryzen™ 3000 Series or newer; Apple M1 or newer.
Memory (RAM): 16+ GB of RAM; Apple silicon: 16 GB of unified memory.
Graphics Engine (GPU): Dedicated Nvidia GeForce, 4GB+ video memory, DirectX 12 capable; Apple silicon: 16 GB of unified memory.
Storage / Hard Drive: High-speed Solid State Drive (SSD) or fast RAID array for flawless local multi-track ISO capture and Replay functionality.

Network Stack & Best Practices

Required Ports & Bandwidth

Bandwidth Baseline: Total bitrate needed x 2 = Required upload bandwidth. Upload speed can be tested at websites such as TestMy.net/upload.

Ensure these network ports are open for traffic:

  • 53 (DNS), 80 (HTTP/HTTPS), 443 (SSL)
  • 1935 (RTMP), 2935 (RTMPS)
  • 3478 / 5349 (STUN/Rendezvous peer-to-peer)
  • 5353 (mDNS for local NDI source discovery)
  • 5960-59xx (NDI port range, 1 port per active source)
  • 7272 (Remote Desktop Presenter)
  • 49152-65535 (WebRTC Media/Rendezvous – selected dynamically)
If behind a strict network firewall, check with your streaming target destinations for explicit domain whitelisting guidelines.
Hardware Acceleration Requirements
  • Intel Quick Sync Video: Requires an Intel CPU with an active Intel® QuickSync Video core.
  • NVIDIA NVENC: Requires a dedicated NVidia GPU featuring Kepler architecture or newer.
  • Apple Hardware H.264: Natively utilizes modern Apple Silicon unified pipelines or designated Mac processing arrays.
Rendezvous & Encoding Guidelines

Rendezvous utilizes WebRTC streams which scale system compute targets. Based on single simultaneous 720p30 streams @ 4.0Mbps:

  • Studio (2 Guests): Allocate +4 Mbps bandwidth | i5 quad-core CPU baseline.
  • Pro (7 Guests): Allocate +5+ Mbps bandwidth | i7 quad-core CPU baseline.

High Frame-Rate (60fps) & CPU Stack: Maintained system CPU usage exceeding 60% increases dropped frame likelihood. Consider lowering target canvas resolutions if resource saturation occurs.
