capture devices brings professional connectivity and 
high quality video capture to your laptop or 
workstation. U-TAP SDI is bus powered with the 
ability to simply and easily bring in video across

directly in macOS X®, Windows® and Linux®.
  
Pocket Power U-TAP SDI offers 
easy, cost effective and portable solutions for plug 
and play capture that is compatible with Windows, 
macOS and Linux operating systems and a broad range 
of creative applications. From video conferencing, 
streaming, social media, gaming and more, U-TAP SDI

  U-TAP SDI is 
smaller than a smartphone, with USB connectivity 
that provides a quick and easy way to connect SDI 
sources for capture, without the need to install 
additional software drivers. Small enough to carry 
anywhere with you, its bus powered USB connectivity 
ensures you will never be looking for a power 
source.
  U-TAP SDI provides an SDI looping 
output, allowing you to loop through the source SDI 
signal to monitors, switchers and more. U-TAP SDI 
supports frame rates up to 1080p 60, for your HD 
High Frame Rate (HFR) projects.
  
Rugged and Reliable U-TAP is small, 
rugged, reliable and backed by AJA's world renowned 
support. Small enough to fit in your pocket and with 
no power supply to carry, it can go with you 
anywhere.
  Silence defined with no fans or 
moving parts, U-TAP won't detract from the recording 
or streaming experience, but quietly enhance it with 
automatic video scaling and aspect ratio conformity 
based on your application’s requirements, all the 
way up to 1080p 60.
