The ATEM ATEM SDI Pro ISO Switcher from Blackmagic Design is a four-input live-production switcher with an integrated control panel designed for multi-camera live streaming up to HD video to the internet via Ethernet output. It features a USB output that allows you to record the program output as well as record the individual 3G-SDI inputs to an external USB drive (not included). In addition to recording the program stream and individual inputs, the ATEM Mini Pro ISO also records the embedded audio and analog audio inputs, generating a DaVinci Resolve project file of your live stream. This allows you to take your live production into DaVinci Resolve to make tweaks or adjustments using the source material that is already on your USB drive.The ATEM Mini Pro ISO retains the same size, button layout, and rear-panel interface connections as the ATEM Mini Pro, with new electronics that allow for the ISO recording and generation of the DaVinci project file
