3G-SDI to USB 3.0 capture for live producers

The GRACETOP GTUS-SDI2USB222 converts a single 3G-SDI source to USB 3.0 while providing an HDMI loopout for local monitoring. It accepts SD-SDI, HD-SDI and 3G-SDI signals up to 1920x1080 at 60 fps. The device is recognised as a standard webcam on Windows, Linux and OS X without driver installation. Bus power over USB 3.0 eliminates the need for an external supply.

Upgrade from USB 2.0 or software-only capture

Moving from a USB 2.0 dongle raises throughput from 40 MB/s to 300-350 MB/s, enabling full 1080p60 recording without dropped frames. The jump is worth it when streaming to Twitch, YouTube or Facebook at 1920x1080 59.94 fps or when OBS, PotPlayer or VLC must ingest uncompressed SDI directly. It also replaces a separate SDI-to-HDMI converter because the loopout carries 480i through 1080p simultaneously.

Sustained streaming without CPU load

Video and audio processing is handled entirely on the dongle, so the host CPU remains free for encoding and scene switching during long sessions. Automatic input detection locks to 30, 40, 48, 50, 59.94 or 60 fps and scales output to 640x360, 1280x720 or 1920x1080 as required. The aluminium enclosure measuring 78x50x20 mm dissipates heat passively, maintaining stable 300-350 MB/s throughput for hours.

Questions about this item

What physical space does the 78 x 50 x 20 mm capture box need on a desk or rack?

The unit measures 78 x 50 x 20 mm and weighs 130 g, so it fits in a shallow tray or can be velcro-mounted behind a monitor without blocking adjacent ports.

Which step do users most often miss when connecting the SDI source, USB 3.0 cable and HDMI loop-out?

Plug the SDI source into the single SDI input, connect the supplied USB 3.0 cable to a blue USB 3.0 port, then attach the HDMI cable to the HDMI output — the device appears as a webcam instantly with no driver install.

What part will need replacement first if the box is used daily for live streaming?

The included USB 3.0 and HDMI cables are the only consumable items; the capture box itself has no fan, no internal battery and no user-serviceable components.
