4K SDI Capture via USB
The Magewell USB Capture SDI 4K Plus bridges the gap between 4K broadcast infrastructure and computer-based production. It captures 6G-SDI signals at up to 4K 30fps with full embedded audio, and is fully backward compatible with 3G-SDI, HD-SDI, and SD-SDI sources.
Why Choose the SDI 4K Plus?
As broadcasters and production houses upgrade to 4K cameras, you need a capture device that can keep up. This dongle ingests 6G-SDI signals carrying 4K content and delivers them to your computer as a standard webcam feed — no drivers, no complex setup.
The SDI loop-through lets you pass the signal to a downstream monitor or recorder while capturing. The 3.5mm audio input lets you embed external audio from a mixing desk. Built-in cable equalisation supports 6G-SDI runs up to 75 metres, with longer distances at lower data rates.
Future-Proof Your Kit
Because it's backward compatible with every SDI standard from SD through to 6G, this one device works with your entire camera inventory — both current 4K models and older HD gear. StreamKit provides a 3-year warranty and free UK delivery on every unit.
