Broadcast infrastructure from Blackmagic Design was key in the multicam workflow used by Darts in Motion to live stream the Professional Darts Corporation European Tour (PDC). The production company has been involved with events in the Netherlands and Germany in 2014, and are now preparing for tournaments in Austria and Gibraltar alongside three more in Germany later in the year.
The camera chain consists of seven Panasonic PTZ HD cameras connected via SDI to Blackmagic’s Compact Videohub 40×40 router, and an ATEM 2 M/E Production Switcher with ATEM 1 M/E Broadcast Panel is used to produce the master output.
“To give ourselves maximum mobility and flexibility we built our PPU systems into two 14 HE racks on wheels,” revealed Robbert van Loon of Darts in Motion. “Live production being what it is, each job we do for the PDC can have differing requirements. That means we can be working with anything from as few as six inputs all the way up to 16. Because of that we designed a separate SDI input panel as a bridge between our camera and graphics chain and the 40×40 router from Blackmagic.”
“Using the ATEM’s built in Multiviewer, we then live switch the PGM feed using the ATEM Broadcast Panel and overlay graphics using the ATEM’s upstream keyer (USK),” continued van Loon.
The production team then has to duplicate the clean PGM feed, using an SDI Distributor. Another copy of the PGM is also recorded in Quicktime ProRes HQ on a Blackmagic Design HyperDeck Studio SSD broadcast deck for archive purposes, while a second HyperDeck Studio is used to record a backup of the PGM in ProRes LT.
“One of the features we really like on the ATEM switcher is SuperSource. It’s perfect for showing the famous darts ‘split shot,’” explained Robbert. “In years gone by a cameraman would need to adjust his shot every time the split was on. Now we adjust the shots with the ATEM’s built in DVE player. This is a big improvement.”
