What it is

NDI Tools (Vizrt) is the IP-video swiss-army-knife. Tools like NDI Bridge + NDI Closed Caption integrate with speech engines to inject captions into NDI streams. Used heavily in church AV + event production.

Best for: Houses of worship + live event teams running NDI-based video routing with live captions.
Watch out for: Caption surface is integration-led; users still need a speech engine.
