4KTV at SMPTE: Broadcaster Update
U.S. broadcasters have employed 4K on the production side. Bob Seidel of CBS said the network is now acquiring assets in 4K. He also described how the network used 4K for what it’s calling “Heyeper Zoom,” with emphasis on the “eye.” CBS employed six 4K cameras at the Super Bowl to acquire footage at 3840 x 2160 pixels and used the footage for slo-mo replays and highlights.
Beginning of this year, Fox did NASCAR in 4K… acquisition, FOR-A FT-100 and Canon C-500, which was also used for the MLB All-Star Game along with AJA’s KiPro Quad DeBayer. For NFL games, Fox used the Canon C-500 with AJA’s KiPro Quad DeBayer and Corvid Ultra, as well as EVS XT servers.
What Fox has learned with Super Zoom, Callahan said, is that:
- Not every play lends itself to 4K.
- Focus is critical.
- Filtering is needed for extraction.
- Uncompressed is better.
- Motion blur is still a problem with 4K.
- Moving 4x3 Gbps SDI can be difficult.
