Product Overview

The Vizrt Spark Plus IO 12G-SDI (FG-003004-R001) is a compact, bidirectional NDI-to-12G-SDI and 12G-SDI-to-NDI video converter supporting UHD 4K at up to 2160p60. Designed for broadcast engineers and AV system integrators adding 4K IP video to existing SDI infrastructure, it connects via a single Ethernet cable with Power over Ethernet (PoE) no separate power supply required. The Spark Plus IO 12G-SDI bridges SDI-based broadcast facilities and IP production workflows with minimal installation complexity.

Product Description

The Spark Plus IO 12G-SDI handles bidirectional conversion: it encodes 12G-SDI video to NDI for distribution across IP networks, and decodes NDI streams back to 12G-SDI for output to SDI monitors, routers, or downstream SDI equipment. Resolution support extends to 2160p59.94, covering the full UHD 4K broadcast range. Audio handling includes 16-channel encoding from the SDI signal and 8-channel decoding to embedded SDI audio, plus a 3.5mm analog line-level input for embedding and a 3.5mm analog output for de-embedding audio feeds. PoE operation eliminates the need for a local power outlet at the converter position, simplifying installation behind displays, on camera rigs, or in compact rack-mount positions. Program and Preview tally LED indicators provide visual confirmation of on-air status. The web-based UI provides remote configuration and monitoring from any browser on the network. NDI virtual input, multicast mode, and NDI network identification support flexible integration with TriCaster systems, 3Play replay, and any other NDI-capable production equipment. For broadcast facilities adding 4K NDI capability to SDI-centric routing infrastructure, the Spark Plus IO 12G-SDI provides a direct, low-friction conversion path.
