The Blackmagic ATEM SDI Extreme ISO is an 8-input SDI live production switcher combining advanced keying with full multi-stream ISO recording for broadcast-grade SDI productions.
Large SDI rigs need both headroom for creative keying and a safety net of every camera recorded separately. The SDI Extreme ISO handles 8x 3G-SDI inputs, each with its own standards converter, and supports up to 9 layers across 4 upstream and 2 downstream keyers, plus 4 chroma keyers for green screen work on any input. It records all 8 SDI ISO feeds plus the program output as 9 separate H.264 streams over USB-C, and automatically generates a DaVinci Resolve project file for a full post-production re-edit.
