It took me FOREVER to find what IRE stood for. I could not remember for the life of me. I knew it had something to do with Radio Engineers, but the “I”… After Google failed miserably, I turned to the FCP manual. And there it was:
IRE (Institute of Radio Engineers) - Also refers to an analog video signal unit of
measurement for luma, established by the Institute of Radio Engineers.
The IRE level is indicated on the waveform monitor.
