i think the twitch effect from video copilot is a combination of fx and scripting. It uses the speed of a
second layer to drive the blur or the faked chromatic aberration .
So to achieve this fx you would need a module and a combination of filter.
Just like Andrew Kramer did.
And is there a module that let´s one layer follow the motion of a second one ?
I have installed the freeframe Filter but there is not twitch filter.
I found these filter Set:
Maybe there is something you like ....http://vjfx.com/main/en/mmshowcase/mmshopfreeframepacks
But i think to achieve the effect you need a combination of effects.
And i don´t know if i´m wrong , but there is no layer motion blur in MD8?
At least i havn´t found it. I can apply the trace effect, but this is a Master effect.
I hope i could help.
