What is DVI2USB 3.0?
DVI2USB 3.0™ is Epiphan's professional-series external DVI-I video grabber. In a nutshell, it captures images
and video from VGA, HDMIand DVI-I video sources and digitizes them on your laptop or workstation via
connection to a USB 3.0 port.
The video capture workstation can record and/or stream the resulting uncompressed diagnostic-quality
images and videos. On Windows, both audio and video capture is supported for HDMI sources. Thanks to
EpiphanVideo capture technology, this small, portable product connects directly to your computer's USB 3.0
port - no need for a large workstation with a free peripheral component interface (PCI) slot.
DVI2USB 3.0 captures video and audio from any single link DVI, unencrypted HDMI, or VGA source. Meeting
greater demands for transferring larger files at faster speeds, this external video grabber supports USB 3.0
technology, capable of transferring uncompressed data with speeds of up to 5.0 (Gbits/s) - about ten times
faster than USB 2.0.
In practice transfer speeds are dependent on factors such as USB load and hardware
configuration.
DVI2USB 3.0 is versatile and can be used with multiple workstation configurations. It is backward compatible
with USB 2.0 connections, however it transfers video at a reduced frame rate when using USB 2.0.
Using the included Epiphan Capture Tool, DVI2USB 3.0 captures full 1080p HD at 30 frames per seconds and
supports resolutions up to 1920×1200. When working with third-party software, such as Windows Media
Encoder with YUV 4:2:0 chroma sub-sampling, 1080p video is captured and recorded 60 frames per second.
For more information about maximizing the frame rate when capturing, recording and streaming video using
third-party applications, refer to the How to Record Video using Window Media Encoder tutorial on Epiphan’s
website.
