Make video capture effortless
With AV.io SDI+, capturing video from SDI devices on Windows, Mac, or Linux is as easy as using a plug-and-play webcam. Simply connect any 3G-SDI, HD-SDI, or SD-SDI device to one end of the capture card and your computer to the other, then select your device as a source in your software. That’s all there is to it – no driver installation required.

Size and scale effortlessly
There’s no need to think about video scaling or aspect ratios with this capture card. AV.io SDI+ will automatically adjust your image based on the software you’re using, delivering superior video quality even when swapping between sources.

Elevate your favorite apps
You can use AV.io SDI+ with any program that accepts USB as a video source. That includes video conferencing apps like Zoom and Microsoft Teams as well as streaming software such as Wirecast and OBS.

Capture great audio
With high-quality audio capture and more ways to bring audio into your projects, AV.io SDI+ ensures your content will sound as great as it looks.

Bring in your audio
Capture audio directly from your 3G-SDI or HD-SDI source, or through the 3.5 mm input to capture from a mixer or other external sources. You can even bring in audio from both inputs simultaneously.

Minimize noise
Whisper-quiet performance makes AV.io SDI+ a silent addition to your workflows, meaning it won’t add noise or distract from the task at hand.
