random flicker effect
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??

wow thanks for the rapid response and solution i’m not too up on scripting and i know this is a really dumb question but how do i enter the scripting into the program ??

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 )

thats fantastic thank you so much for the super quick response, my new random flicker clip is just rendering now!!! are there many other little scripts like that or any websites that have help on building them/examples of them…?? i was aware it was do-able but hadn’t looked into it much….. thank you again…. i really appreciate it

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.D O N E

Hi Andy,
i am editing an hip hop music video on final cut pro and i would like to use the flicker effects as weel. i read your instructions but i failed several times. is there a way you can please email me the filter so i can install it. Thank you so very much for your help.
the client ask me for lens flare and blink effects as well. that is not a prob. i have used them before. but any idea will be welcome. -
Step 9?

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 –>
