Quickstart, or deep dive, our user guide has got you covered.
AV.io SDI has no drivers to install? How does it work then?
AV.io SDI is a USB Video Class (UVC) and USB Audio Class (UAC) drivers. These drivers come with the operating system, meaning there is no software for you to install and configure!
Since AV.io SDI has no driver software, what do I need to capture video content?
To capture video content with AV.io SDI, you will need to 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. Nearly every application that works with web cameras works with UVC hardware like AV.io SDI.
Are there any configuration options at all with AV.io SDI?
Available through the Downloads page, AV.io Config allows users several basic configuration options. Users can enable/disable special capture frame sizes, select the audio pair for capture, set aspect ratio preservation, choose power-saving performance mode, and update firmware on their AV.io SDI device.
Can I capture 3G-SDI with my AV.io SDI?
Absolutely! AV.io SDI supports video capture from 3G-SDI, HD-SDI and SD-SDI and audio capture from 3G-SDI and HD-SDI.
Can I capture VGA with AV.io SDI?
Can AV.io SDI save captured signals as a movie?
Using any third party application that supports UVC capture devices, you can save your captured content as either images or as a video (depending on the options available in the 3rd party application). For example, using VLC you can easily save your SDI signal as a video on your computer.
What interface is needed for AV.io SDI?
AV.io SDI connects to your computer via USB. It works best with USB 3.0 (SuperSpeed), but can also work with reduced performance (and without audio capture) when plugged into a USB 2.0 port.
How can I verify whether my system has USB 3.0?
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.
How many frames per second can AV.IO SDI capture?
AV.io SDI captures video at 60 fps for any resolution up to 1080p unless the application specifies a different frame rate.
Does AV.io SDI scale or reduce the resolution of the images it captures to transfer to the computer?
That depends! For example, if 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.
Does AV.io SDI work with operating systems not listed in the technical specifications?
Because AV.io SDI uses USB Video Class (UVC) and USB Audio Class (UAC) drivers, it should work on all UAC/UVC compatible operating systems. However we only test and support the subset of OSes listed in our technical specifications.
Can I use different video sources with AV.io SDI while maintaining the same capture signal?
Yes. Unless you have changed the advanced configuration settings, you can change your video source (e.g. change what is plugged in to the SDI end of the AV.io SDI) and video capture will not be paused or interrupted. The exact content of captured screens while nothing is attached to the SDI port is not guaranteed.
The video output resolution that I want is not listed in the list of supported modes for AV.io SDI. Can AV.io SDI capture at this custom resolution?
Yes. Using AV.io Config, you can configure AV.io SDI to add the exact resolution of your input signal to the list of supported output resolutions. If the capture application chooses this resolution, AV.io SDI will capture video at this special resolution.
Can I connect more than one AV.io SDI device to the same computer?
You can connect up to 4 AV.io SDI devices to the same computer, however the USB bus can become overloaded, causing reduced capture rate (fps). Test with different USB ports to determine the limits specific to your computer’s configuration.
Does AV.io SDI use frame compression when capturing video content?
No, AV.io SDI sends uncompressed video to the capture computer. Compression may happen when you save the signal as a video (e.g. when you save with a codec like H.264).
Will AV.io SDI have firmware updates?
AV.io SDI will have occasional firmware updates. Customers who have registered their AV.io SDI will be notified via e-mail of any new firmware upgrades. The product registration page can be found here.
What is the capture delay when capturing with AV.io SDI?
AV.io SDI has near-zero latency (capture delay). However, third-party applications may introduce some delay. If low latency is important, test with various capture tools to find the one that introduces the least delay possible.
Help! My image appears reversed in my capture application!
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!
There are black bars on either side of my captured video content! How do I get rid of these?
By default, AV.io SDI 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.
These downloads give you access to the latest developments for your device. You can load this firmware onto your device using the AV.io Config tool. You can learn the full process for updating Firmware in our user guide.
AV.io SDI firmware
For most uses of AV.io SDI, the configuration tool is not required. However, it is necessary for installing new firmware, and for advanced usages such as creating custom resolutions.
AV.io Configuration Tool. When installing on Windows 10, you may need to right-click the file and choose Run as administrator.
*For Windows 7 64-bit, please use this version of the configuration tool.
