    i am trying to produce the effect of one clip flickering in and out over another clip. I have used the blink effect but this is not random enough and looks stilted if i edit the effect parameters time line thingy (sorry for not knowing the technical name…). I am only using final cut so anything with motion or after effects etc is out…. any one have any suggestions??

    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.

    Hah! I think step 9) might have been something about christening the effect with a cold one from the fridge. Seriously tho, My mate Luca Bono built a really cool flicker filter which I highly recommend … grab it here –>
