I've had a look online and I can't find anything so thought I'd ask here.
Does anybody know the best way to create a flicker effect?
I essentially want an effect to flicker on and off like a strobe/flickering neon sign.
I've tried doing it mathematically using random/gate/hold but it's not just creating the desired effect of having it flicker on very quickly and for very short periods.

Try this with a mask, you can always blur it if the line is an issue.

Perhaps you want something more sophisticated but a randomised transparency seems to be acceptable to me.
First Random controls the full ON/OFF flicker and the second the more subtle flickers. The offset controls the intensity and the threshold controls the amount of full ON/OFF.

Visuality, I was hoping to get it to flash at random so that ISF isn't suitable unfortunately, thanks for you help though!
Sadler, after having a fiddle this has done the trick great. Thank you!!

increase the ramp value to get it to strobe faster
