Changes since 4.1.3
  • macOS releases now use the NDI runtime installed from the redistributable.
  • Source:
    • Lower input latency
    • New "Sync" option. You can choose between "Internal" (generate frame timestamps locally) or "Network" (use NDI frame timestamps). Use "Internal" mode if you encounter audio desync issues.
    • New "Bandwidth" option (replaces the "Low bandwidth" checkbox). You can choose between "Highest", "Lowest" or "Audio Only".
  • "Dedicated output" filter:
    • Lower output latency
    • New "NDI name" option. Dedicated output NDI name is now independent from the filter's name.
    • Now compatible with audio-only sources (like the Desktop audio source).
Windows, Linux and macOS Install instructions: see the release page on GitHub.
