AV.io 4K UserGuide Getting started

Getting started

Welcome and thank you for buying Epiphan Video’s AV.io 4K!

This guide contains all the information necessary to successfully use AV.io 4K to quickly and easily capture live
video content without any configuration – simply connect the cables and you’re ready to go!

This guide starts off by jumping right into it by showing you how to start capturing video, then we’ll take you
through how AV.io 4K works, followed with some technical referencematerial, and we’llconclude with a
walkthrough of some optional video capture configuration.

Let’s get started!

About AV.io 4K

AV.io 4K is the latest addition to Epiphan Video's industry-leading video grabbers product line, adding 4K
resolution support whilemaintaining support for HD and SD resolutions. To use AV.io 4K, there's no software
to install; simply connect the cables and go. It works on Windows,Mac and Linux and integrates seamlessly
with your favorite third-party applications such as Skype, Adobe FMLE, Wirecast, VLC mediaplayer and
Quicktime.

AV.io 4K captures resolutionsup to and including4096×2160, making it the simplest way available to capture
DCI 4K and 4K UHD digitalsignals.

For those curious as to the difference between DCI 4K and 4K UHD, these arejust different definitions of a 4K
resolution. 4K UHD (3840×2160) is the standard 4K resolution available on televisions and other common
display screens. The 4K resolution of 4096×2160 is referred to as Digital Cinema Initiatives (DCI) 4K, and is the
resolution used almost exclusively for cinema-scale film production. It is rareto find this resolution outside of
a cinematiccontext. AV.io 4K is capableof supportinginput and output at either.

AV.io 4K UserGuide Indicator LED details

Indicator LED details

The color and action of the indicator LED depends on whether you are connected by USB 3.0 or USB 2.0. For
maximumperformance, always use a USB 3.0 port and the included USB 3.0 cable. Note that frame capture
rate will be reduced when connected via USB 2.0, and it is likely that any attempt to use4K resolutions with
USB 2.0 will be unstable.

From the operating system's UVC drivers, the application will receive the AV.io 4K supported colorspace,
resolution and frame rates. If you’re not sureif your controller is USB 3.0 or USB 2.0, plug AV.io 4K into the
capture computer and look at the indicator LED. After initial boot up(red LED), blue is used for USB 3.0 and
green is used for USB2.0:

AV.io 4K UserGuide How AV.io 4K works

How AV.io 4K works

Once you’re ready to start capturing, you’ll need either a built-in or third-party application to capture video
and audio content with AV.io 4K.

The application communicates with AV.io 4K and negotiates a color format (the range of available colors),
frame rate (frequency at which frames in a video sequence aredisplayed) and frame resolution (size of a
singlevideo framein pixels). Higherframe rate means smoother video capturewhile resolution determines
the aspect ratio of the video output as wellas its resolution and degreeof definition.

With the help of AV.io 4K, the content from your video source is automatically configured and captured on
your computerthrough your selected application. If the application requests a framesize that is smaller or
larger than your video source, AV.io 4K automatically scales the video for you. For consistent and widely
compatible output, audio is automatically resampled to 16-bit 48 kHz stereo audio.

No configuration required!
