6G-SDI 4K to full NDI encoder with loop-through.
Ask us a quick question about this product — signal compatibility, use case fit, or anything technical. We usually reply the same day.
The Pro Convert SDI 4K Plus encodes 6G-SDI 4K30 to full-bandwidth NDI with an active loop-through. It is the bridge for 4K SDI cameras that output single-link 6G-SDI (most current cinema and broadcast cameras) into NDI-based IP production workflows.
Full backward compatibility with 3G, HD and SD-SDI is built in, so the same device can encode 1080p60 from an HD camera in one production and 4K30 from a cinema camera in the next. The loop-through means the SDI signal continues feeding downstream broadcast equipment while NDI encoding runs.
PoE-powered, standalone, configured via web UI or Control Hub. For broadcast 4K NDI workflows it is the standard recommendation; if your cameras output 12G-SDI 4K60 instead of 6G-SDI 4K30, look at the Pro Convert 12G SDI 4K Plus variant.
