AV.io HD is a UVC-based capture device. The supported operating systems that work with AV.io HD already have the drivers required to run UVC hardware, meaning there is no software for you to install and configure!

To capture video content with AV.io HD, you will need a software application that works with UVC hardware. Some such applications are native to certain operating systems, while most others need to be downloaded and installed from a third-party source.

Available through the Downloads page, AV.io Config allows users several basic configuration options. Users can enable/disable special capture frame sizes, aspect ratio preservation and a power-saving performance mode; and apply firmware updates to their AV.io HD device.

Absolutely! You may capture both video and audio from an HDMI signal using a HDMI-DVI converter cable, included in the box. Note that AV.io HD cannot capture a protected or encrypted HDMI signal.

Yes, you can capture video from a VGA source using the VGA to DVI cable provided with your AV.io HD purchase.

AV.io HD cannot save captured video as a movie on its own, but compatible third-party video capture applications may have the ability to do so.

AV.io HD is compatible with both a USB 3.0 (SuperSpeed) and a USB 2.0 USB interface. Note that capture performance via USB 2.0 can be reduced.

USB 3.0, also known as SuperSpeed, comes standard on all computers manufactured after 2011. Check with your computer or motherboard manufacturer to verify that USB 3.0 is present on your system.

AV.io HD can capture at 60 fps at any resolution up to 1080p unless the application specifies a different frame rate.

That depends! For example, the source input resolution is smaller or larger than the output resolution selected by the third-party application in use, then capture resolution will be affected accordingly.

AV.io HD is designed to work with all UVC-friendly operating systems, specifically Windows 7, Windows 8.1, Windows 10, Mac (x10.10 and up) and Linux (kernal 3.5.0 or higher). Unfortunately, operating systems not listed have poor support or no support at all for USB 3.0 and UVC-based capture hardware.

Yes, changing video sources will not negatively impact the capture signal.

Yes. By default, AV.io HD adds the exact resolution of your input signal to the list of supported output resolutions and will capture video at this special resolution if possible. However, the capture resolution as dictated by the third-party application will override any AV.io HD custom capture settings.

You can connect up to 4 AV.io HD devices to the same computer, however the capture rate (fps) will suffer with simultaneous video capture.

No, AV.io HD uses uncompressed video format.

Yes. AV.io HD can capture unencrypted images and video from DisplayPort, Mini DisplayPort and Thunderbolt outputs. In order to capture video from these formats, the appropriate converter cable must be purchased separately. Epiphan does not guarantee results when using third party cables.

AV.io HD will have occasional firmware updates. Customers who have registered their AV.io HD will be notified via e-mail of any new firmware upgrades. The product registration page can be found here.

AV.io HD has near-zero latency. However, third-party applications may cause additional capture delay.

This is just a visual quirk – image mirroring happens with most UVC-friendly applications. But don’t worry! All captured video content will appear correctly despite appearing reversed in your application!

By default, AV.io HD preserves the aspect ratio of your input signal by adding black bars to the sides or top and bottom of the frame if the application using the signal requests a frame size with a different aspect ratio. This aspect ratio preservation option can be disabled by using the AV.io Config tool found on the Downloads page.
