Rock-solid SDI-to-USB video capture

Portable and reliable SDI capture card
Epiphan SDI+™ brings USB plug-and-play convenience to your SDI sources. You can easily capture 1080p video from any SDI camera or device with nearly zero latency, bringing in audio through HDMI, the 3.5 mm input, or both. This card is compact and based on tough-as-nails technology that’s even been used in space, so you can confidently carry it wherever there’s video to capture.

Make video capture effortless
With 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.

Take your capture card with you SDI+ is light and compact. It’s powered over USB, which means one less adapter to carry around. And with its rugged all-metal exterior and durable connectors, it’ll stand up to repeated, long-term use.

Size and scale effortlessly
There’s no need to think about video scaling or aspect ratios with this capture card. 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 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, 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 SDI+ a silent addition to your workflows, meaning it won’t add noise or distract from the task at hand.
