Direct 12G-SDI Multi-Channel I/O
for iPad Pro

ThunderFace 4K Duo+ provides direct 4-channel 12G-SDI I/O for iPad Pro, without compromising signal quality, metadata transmission, or standard output frame rates in professional video environments.


A new approach leveraging modern, high-performance tablets, which combine substantial computing power in a slim form factor with color-accurate HDR displays capable of precise image evaluation, along with the flexibility to run multiple productivity applications simultaneously.
When integrated with iPad Pro and the free QTAKE Monitor application, ThunderFace 4K Duo+ enables a portable, professional multi-camera SDI monitor-recorder without ongoing software licensing fees. ThunderFace 4K Duo+ handles input and output, while the iPad Pro runs QTAKE Monitor for recording, playback, clip database, metadata management, LUTs, scopes and more.
