NEW – Added the ability to use an iOS device as a camera source on your Local Area Network (LAN) via Wirecast Go 2.1Īdded the ability to create 60 FPS encoder presets for RTP Unicast/Multicast streamsĪdded a drop-down option to YouTube destination to list Live, Upcoming, Completed or All eventsįixed a crash when creating a new document on macOS High Sierra 10.13.2įixed a crash that could occur when adding CEF-based widget sourcesįixed a problem where some sources were providing black video on Windows 7įixed issues with video quality when scaling the Canvas Size relative to the encoder resolution NEW – Added the ability to switch Shots with three supported MIDI Controllers (Akai APCmini, Akai APC40 MKII, Novation Launchpad) Maintained system CPU usage greater than 60% will increase the likelihood of dropped frames. Simply switching to a higher frame-rate without ensuring the CPU and bitrate are sufficient may result in a lower quality encode.Ĭonsider lowering your canvas frame rate and/or streaming resolution to lower CPU usage. High frame-rate streaming will result in increased CPU usage and a require a higher bit rate (4Mbps or higher) for a quality encode. At the time of this writing, only Quick Sync via an Intel GPU is supported. *This may change in the future, as the Apple API decides what hardware acceleration method is to be used. NVIDIA only maintains a general list of supported GPUsĪpple Hardware Accelerated H.264 encoding requires a Mac with an integrated Intel GPU*. ![]() NVIDIA NVENC encoding requires an NVidia GPU with Kepler architecture or newer. Intel Quick Sync Video encoding requires an Intel CPU with an Intel® QuickSync Video core. Hardware accelerated encoding requirements: Total expected data rate should be compared to available disk write speed to ensure adequate disk throughput.įailure 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).

Solid State Drive or fast RAID array recommended for ISO Recording and Replay functionality.Īctual data rates will vary depending on quality level selected for ProRes (Mac) or MJPEG recording More demanding workflows may require a more capable CPU. 6Minimum recommended processor with example stream4. For the best experience, we suggest considering the following table when choosing hardware:ĤBased on a single simultaneous stream of 720p30 x264 4.0Mbps.ĥBandwidth per guest will scale downwards as more are added to maintain reliability. Wirecast Rendezvous uses WebRTC technology that can be very resource intensive.
