5. Advanced connectivity for livestreaming workflows
Canon offers camera solutions ideally suited for integration into livestreaming workflows with a variety of outputs, such as HDMI or more robust connections, such as SDI for linking to live production switchers.
"A camera's connections are the basic prerequisite for integration into a professional production environment, and SDI is mandatory," says Thorsten. "The 12G-SDI output of the Canon XF705 has very low latency and provides a secure cable connection." The Canon XF605 also features 12G-SDI output, which supports high resolutions and frame rates, including 4K 4:2:2 10-bit signals up to 60p over a single cable.
In addition to their 3G-SDI and HDMI terminals, both the Canon XA65 and Canon XA75 are equipped with a USB-C output which supports Full HD UVC streaming in Windows or MacOS. The Canon XA60B and Canon XA70 also come with the convenience of UVC compliant USB-C connections, ensuring that they're easy to set up and use with camera applications on your computer.
IP streaming capabilities also feature in many Canon cameras, including the XF605, EOS C70 and EOS C300 Mark III. "Although these will need a decoder connected to the camera, it means the signal is already in the required format to be efficiently streamed over a network," says Aron.
"Some people may want to simply take the HDMI or SDI output and put that into a production switcher, which will then encode it and stream it live. An alternative that requires less hardware, however, is to have your cameras connected to a local area network and then go through an IP-based livestreaming software solution. It's another option to consider when you're choosing the right workflow for your needs."
Support for SRT (Secure Reliable Transport), a broadcast-standard protocol that enables high-quality streaming in unstable or unpredictable network conditions, comes as standard with the CR-N700 PTZ camera, and it's also available for the CR-N500 and CR-N300 via a firmware update. The CR-X300, CR-N700, CR-N500 and CR-N300 also support RTMP/RTMPS (Real-Time Messaging Protocol and Real-Time Messaging Protocol Secure), which enables content to be shared directly to platforms such as YouTube and Facebook.
The Covid-19 pandemic forced everyone to adapt their workflows, and livestreaming continues to be an essential part of the content creation mix. Canon is excited to be able to support this burgeoning area of production with tools that work effortlessly together, enabling users to focus on the content.
