I am new to FCPX and have been using it for the past month or so.
In my current project I would like to be able to make the screen strobe/blink/flash at a certain rate per minute - specifically between 8-13 per second over the top of the footage I have, rather than replacing it.
I have tried to achieve this with the 'flashing' effect in the video filters menu but I can't seem to adjust anything other than the 'intensity' which seems pointless.
I have searched for similar questions and answers but can't find an answer for this with FCPX.
I have seen the blink filter discussed but I don't think this is in FCPX
