Upgrade Information
An internet connection is recommended for Wirecast license activation.
As long as your Wirecast (version 8 or higher) license is entered into the software and your Wirecast Access Plan is active, you will be allowed to upgrade to the latest unlocked version of Wirecast for free.
Add-ons
Remote Desktop Presenter – Please use the Remote Desktop Presenter version 2.0.8, available as a separate download from Telestream: www.telestream.net/dtp.
PLEASE NOTE: Wirecast 9 and later versions have dropped support of HDV licenses/cameras. Please click here for additional information.
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 TestMy.net/upload.
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
Rendezvous
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)
Bandwidth4 – Add 4 Mbps | Processor4 – i5 quad-core5
Pro (7 guests + 1 host)
Bandwidth4 – Add 5+ Mbps6 | Processor4 – i7 quad-core5
4Based on a single simultaneous stream of 720p30 x264 @ 4.0Mbps.
5Minimum recommended processor with example stream4. More demanding workflows may require a more capable CPU.
6Bandwidth per guest will scale downwards as more are added to maintain reliability.
See our Rendezvous Best Practices Guide for more information.
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.
For ProRes recording please refer to Apple’s ProRes data rate specifications.
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 bitrate (4Mbps or higher) for a quality encode.
Simply switching to a higher framerate 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.
