random flicker effect

scriptid "Random Blink" //DO NOT LOCALIZE
filter "Random Blink"
group "Video";
producesAlpha;

input op, "Opacity", slider, 0, 0, 100 detent 0;
input blinkAmount, "Amount", slider, 0.5, 0, 1;

InvalEntireItem
RenderEachFrameWhenStill
fullframe;
code
exposedbackground = 1;

float doBlend;
doBlend = Random (0, 1);

if (doBlend < blinkAmount)
dest = src1;
else
channelfill(dest, 0, 0, 0, 0);
blend(dest, src1, dest, op/ 100);
end if;

1) open FCP
2) right click the Flicker filter in the Effects bin and choose Open in Editor
3) select all the text that appears in the subsequent FxBuilder window and press delete
4) now copy and paste the text of that effect in its place
5) go to the FxBuilder menu and choose Create New Plugin (or words to that effect)
6) save the plugin on the desktop
7) then copy it into /Library/Application Support/Final Cut Pro System Support/Plugins
8) relaunch FCP


... failing that just bung me a email (address is in my profile) and I'll email the filter to you and then you can install it in the Plugins folder as above and relaunch FCP ( steps 8 and 9 )

Random "anything" goes directly into Motion.

Stack the two clips
Apply the parameter behavior "Randomize" to the Opacity parameter of the overlaying clip.
Tweak to taste.
