User Guide Indicator LED details
Indicator LED details
The color of the indicator LED depends on whether you are receiving power from the USBport and
whether or not a video source is connected to the input port. If the USB is plugged into a PC and there is
no video source connected to the input the LEDwill be solid red. Once an active video input is detected
the LED will turn solid white.
From the operating system's UVC drivers, the application will receive the AV.io HD+ supported color
space, resolution and frame rates. UVC stands for Universal Video Class and describes a type of USB
device that uses standard drivers that come automatically installed on most operating systems.
LED color USB/Input connection

User Guide How it works
How it 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 HD+.
The application communicates with AV.io HD+ and negotiates a frame rate (frequency at which frames in
a video sequence are displayed) and frame resolution (size of a single video frame in pixels). A higher
frame rate means smoother video capture while the frame resolution determines the aspect ratio of the
video output as well as its dimensions and degree of definition.
With the help of AV.io HD+, the content from your video source is automatically configured and captured
on your computer through your selected application. If the application requests a frame size that is
smaller or larger than your video source, AV.io HD+ 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!

User Guide Set up your device for capture
Set up your device for capture
To connect your AV.io HD+ for capture:
1. Connect your AV.io HD+ device to your video source, ideally directly to the source, but some video
sources may require special adapters
2. Connect your AV.io HD+ device to your desktop computer, laptop, or notebook
3. Open your favorite third-party application, select AV.io HD+ from the list of available input sources,
and start capturing!
And that’s it! No drivers to install and no extensive set-up! Just connect the cables and you’re ready to go!

User Guide Resolutions, aspect ratios, and capture rates
Resolutions, aspect ratios, and capture
rates
The resolution (also known as frame size or display mode) of a video signal, digital image, TV screen,
computer monitor or other display device is a count of the number of pixels displayed horizontally and
vertically. For example the resolution 1920×1080 (which is 1080p) creates an image that is 1920 pixels
wide and 1080 pixels tall.
The aspect ratio of an image describes the proportional relationship between its pixel width and height.
The resolution 1920×1080 (1080p) is quite a bit wider than it is tall. The ratio of its width to height is 16 to
9, represented as an aspect ratio 16:9.
AV.io HD+ outputs resolutions in commonly supported aspects ratios. The table below is a color-coded
legend for interpreting the table of product resolutions below it:
Aspect Ratio Common Use
4:3 Standard TV (NTSC/PAL) display and non-widescreen computer displays
16:9 Widescreen (HD) TV displays (1080p, 1080i, 720p etc.)
16:10 (8:5) Widescreen computer displays
5:4 Sometimes used in larger format computer monitors
AV.io HD+ generates a list of the following possible resolutions for your capture application to select for
output display:
640×360 848×480 1024×768 1280×1024 1920×1080
640×480 960×540 1280×720 1600×1200 1920×1200
Captured video content is output to your application at between 5 and 60 frames per second (your
application chooses one of these frame rates) when captured over USB 3.0. This table is not an exhaustive
list of all the resolutions your AV.io HD+ can output, just a list of common and tested resolutions.
13

User Guide Automatic image scaling & audio resampling
Automatic image scaling & audio res-
ampling
If your source content is larger or smaller than the frame size chosen by the application, AV.io HD+
automatically scales your source to match the desired frame size. No user configuration required!
AV.io HD+ also automatically performs audio resampling, meaning that no matter the bit depth or
sampling frequency of audio through an HDMI audio source, AV.io HD+ automatically resamples your
audio so that your application gets a consistent audio sample rate and bit depth, even if you change the
video source.
14

User Guide Third-party applications
Third-party applications
AV.io HD+ 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 HD+'s use of UVC/UAC technology, there is
no need for driver installation. Just like a webcam, your AV.io HD+ device is immediately recognized as a
camera device and can be used to capture content via any UVC-compatible third-party application.
Third-party applications that work with AV.io HD+ include, but are not limited to the following list. Try your
favorite capture application!
Zero-install applications (included with your OS)
Windows Camera app
(with Windows 8.1, Windows 10, and up)
QuickTime
(with Mac OS X, and up)
