Teradek's latest edition of multi-camera switcher software Live:Air Action is now available for download on the App Store. Teradek demonstrated how the app can be used at a small, local event to switch between multiple cameras and stream to 3 different video platforms simultaneously.
Live:Air Action connects up to 6 cameras feeds together for mixing, using iOS devices (iPhones, iPads & iPod Touches) as camera sources or video cameras linked with Teradek encoders as camera sources.When you connect all the devices to the same WiFi network that Live:Air Action is on, the app picks up the camera sources and populates them on the camera select screen, which you can choose for live editing and switching.
For a mini concert held by musician Rebecca Jade, Teradek deployed multiple cameras around the venue and used Live:Air Action for live switching and broadcasting to multiple destinations using only a single cellular connection.
Teradek said in a blog post - "We set up 3 cameras in different spots all pointed to the stage. 2 Canon HF-G20s on Manfrotto tripods were placed on both sides in front of the stage to capture close-up shots, while a Canon XA-10 was placed on a Redrock One Man Crew further back to capture the cover shot.
Each camera was connected to its own VidiU Pro encoder, which were all connected to the same WIFi network provided by a Link. This allowed our Live:Air Action app to automatically detect the 3 camera feeds and populate them in the app’s control surface.
When the concert began, we had two crewmembers controlling pan & tilt of the two front cameras, while the back camera rotated left and right automatically from the One Man Crew. These feeds were sent to our switching operator’s Live:Air Action app, where he controlled the feed being broadcast.
Using the Internet connection provided by a Node USB modem with a T-Mobile SIM (connected to the Link), the feed was sent from Live:Air Action directly to our Core management account. From Core, the feed was broadcasted to 4 separate video platforms: 1 Facebook Page, 1 Periscope Channel and 2 YouTube Channels. With the Node providing 26 Mbps to our Live:Air Action app, the stream from Live:Air Action fed Core perfectly."
Teradek commented "Using this collection of live streaming solutions, we were able to achieve a superb low-cost HD multi-camera broadcast without needing enterprise-grade production equipment of traditional large workflows. At the same time, simulcasting with Core meant the event was able to reach 4x the audience of a normal, single-destination stream without needing additional bandwidth or hardware."
