6G-SDI 4K capture in a USB dongle — professional broadcast SDI at 4K.
Ask us a quick question about this product — signal compatibility, use case fit, or anything technical. We usually reply the same day.
The USB Capture SDI 4K Plus brings 4K SDI capture into the portable USB dongle form factor. Using single-link 6G-SDI input it captures 4K video at up to 30fps, with full backward compatibility for 3G, HD and SD-SDI sources.
For broadcast and live-production teams who need a portable 4K SDI capture device — for field production, fly-pack rigs, OB-truck temporary builds, or laptop-based monitoring — this is the most compact option available. The dongle is small enough to live in a kit bag yet captures the full 4K resolution from professional broadcast cameras.
The active SDI loop-through keeps downstream broadcast monitors and switchers running while capture is active. FPGA processing means the host laptop's CPU stays free, allowing comfortable simultaneous streaming or recording.
