3G-SDI to full NDI encoder with loop-through — broadcast SDI into your IP network.
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 Plus is the broadcast-grade SDI to NDI encoder — the same SDI-to-NDI engine as the SDI TX but with an enhanced management feature set and higher-channel audio support. Up to 16-channel SDI embedded audio is preserved through the encode.
For broadcast facilities, OB trucks, and high-end live-production environments where the SDI feed needs to retain full audio and metadata through the NDI conversion, this is the encoder we recommend over the simpler SDI TX. The enhanced management makes it easier to integrate with broadcast automation systems and remote production workflows.
Compatible with every NDI source on the network: vMix, Wirecast, NewTek TriCaster, OBS via the NDI plugin, and any other NDI-compatible system. PoE-powered with active SDI loop-through so the SDI chain continues uninterrupted.
