Using NDI Video in FAB Subtitler

NDI Video can be used in FAB Subtitler for the following functionality:

  • Insertion of open (in-vision) subtitles into video
  • Timecode reading

All above functionalities will work at the same time and they have been tested successfully with different NDI streams.

Required NDI Version

NDI Version 5.6 was tested by FAB and works correctly. Earlier versions may produce errors.

Configuration for Insertion of open (in-vision) subtitles into video

  • In “Options>System>Output devices" activate NDI, select the input stream and define the name of the output stream:

FAB Subtitler will automatically detect the format of the NDI video and create bitmaps with subtitles in appropriate resolution which will be overlaid over the video.

  • To start inserting subtitles into video click on “ON AIR" in FAB Subtitler

  • You can select whether FAB Subtitler shall insert open subtitles into NDI Video or it shall simply provide NDI Video with Fill&Key signals. The Fill&Key operation is described here.
