A faster upgrade to its predecessor, the UltraStudio 4K Extreme, Blackmagic Design UltraStudio 4K Extreme 3 is built with a Thunderbolt 3 interface, which features a 40 Gbps transfer rate that better supports 4K ingest when working in RGB or stereoscopic formats. The super high speed of Thunderbolt 3 is fast enough for the highest bit depth HDR uncompressed RGB 4K and stereoscopic formats, such as those used for high end feature films. Like the previous model, UltraStudio 4K Extreme 3 still offers PCIe, 12G-SDI, HDMI 2.0, and analog connections, 4:4:4 sampling, and real-time H.265 encoding. It supports 4K DCI and UHD footage in up to 60 fps.
