INOGENI SDI2USB3 SDI to USB 3.0 Converter
The SDI2USB3 brings SDI cameras into the same driverless USB 3.0 workflow as INOGENI's HDMI converters, taking a 3G-SDI input with an active loop-out connector so the same feed can run to a second SDI device without a separate distribution amp. It handles 1080p, 1080i, 720p, 480p, 576p, NTSC, and PAL at up to 60 fps, converting all SD and HD signals to a consistent 4:2:2 8-bit color space on the way out.
Embedded audio is extracted and delivered as two-channel LPCM alongside the video, and the card is UVC-compliant so it works with DirectShow-based capture software as well as conferencing platforms. It's built for rooms that standardized on SDI cameras rather than HDMI, and is compatible with Logitech UC cameras and codecs, Barco ClickShare Conference, Zoom Rooms, and Microsoft Teams Rooms.
