ThunderFace 4K Duo Device


Video assist profession requires dedicated tools, designed to provide the finest monitoring and playback experience. Introducing ThunderFace 4K Duo, output device made for QTAKE Pro.



Zero-latency Processing

ThunderFace converts DisplayPort output of the computer directly to SDI signal, without internal buffering. In this mode, SDI outputs are limited to same frequency, but video output is delivered with lowest possible latency.

8x SDI Output

Using high resolution DisplayPort output from the Mac running QTAKE Video Assist software, ThunderFace device can deliver eight separate HD or two Ultra HD outputs in perfect sync, using 3G-SDI and 12G-SDI standards.

Single Cable Connection

ThunderFace device connects to your Mac using a single cable which provides video, audio and control data transfer. Additionally, in case of MacBook Pro, it also charges your computer with 60W power delivery standard.

Quiet Active Cooling

Innovative, whisper-quiet fan from the iconic Noctua brand is integrated within the user-replaceable part of the chassis to keep the device running at low temperature even with the most demanding dual 4Kp60 setup.

Metadata Support

In addition to video and audio content, ThunderFace device can deliver separate metadata for each SDI output, including LTC and VITC timecode, camera positioning data for VFX, as well as HDR and Dolby Vision metadata.

Firmware Updates

Shipping device firmware provides functionality listed in the Features section. ThunderFace is based on a powerful programmable hardware platform, which enables future extension of functionality via firmware updates.
