Usage Notes

Sorry, there’s no proper ReadMe as yet.

You can probably work out the basics for this app – load some NDI® sources into the inputs using the drop-down menus under each input channel, click on the small screens to select that input, shift-click to select to Preview, press Take or the Enter key to switch Preview/Program. You can also use the top row of keys, 1,2,3,4,5,6 to cut inputs to Program, and the row below, the Q,W,E,R,T,Y keys to select inputs to Preview.

For the audio, you select one input as the Master audio, but if you want the audio to change to particular inputs when selected, then enable the AFV (audio follow video) button for that input. PFL (pre fade listen) allows an audio input to be monitored via a different audio device (so you can check it while it is not “on air”.

There are no audio level controls for the NDI® stream – everything (video & audio) is simply copied from input to output for minimum latency – but the monitor outputs (Program & PFL) have three-way “dim & cut” controls – the loudspeaker icon. Click near the top for “full”, in the middle for “dim” and near the bottom for “cut”.
