AV.io 4K User Guide

Automatic image scaling & audio resampling

Automatic image scaling & audio resampling

If your source content is larger or smaller than the frame size chosen by the application, AV.io 4K
automatically

scales your source

to match the desired frame size! No user configuration required!

AV.io 4K also automatically performs

audio resampling

, meaning that no matter the bit depth or frequency

of audio through an HDMI audio source, AV.io 4K automatically resamples your audio so that your application
gets a consistent audio sample rate and bit depth, even if you change the video source!

Third-party applications

AV.io 4K uses pre-installed drivers on your OS (called

UVC drivers

and

UAC drivers

) to communicate with

third-party applications and capture content. Due to AV.io 4K's use of UVC/UAC technology, there is no need
for driver installation. Just like a webcam, your AV.io 4K device is immediately recognized as a camera device
(like a web cam) and can be used to capture content via any UVC-compatible third-party application.

Third-party applications that work with AV.io 4K include, but are not limited to the following list. Try your
favorite capture application!

Zero-install applications (included with your OS)

Skype

(with Windows 8.1 and Windows 10)

Windows Camera app

(with Windows 8.1 and Windows 10)

QuickTime

(with Mac OS X)
