series of quick camera shakes with abberations

I'm mind boggled about doing that seem rather simple.

I am trying to achieve a series of transitions that involve camera shakes with camera abberations effect. It take me a while to make a single one and I am barely satisfied with.

What I do is to separate the logos in 3 layers different in additive blend mode and apply a wiggle on each of them, but it doesn't look professional and it take a while to tweak, I need to do this about 10 times for each logos. Heck. I won't bother getting a pluggin that can do it.

Wiggling is the hardest part because I am doing it manually. Maybe I can make it more simple with a slider control effect expression, but I never used it yet.

A concrete example is this YT Slideshow, which is about the same thing I try to achieve:

I don't see your example, but check out this thread from last year. I even uploaded a example file. See if that gives you a start. Camera Twitch/Shake Colour transition

You could try this.

Use this expression as an interactive, keyframeable Wiggler. Apply it to the property of the layer you wish to wiggle.

wigfreq = 3; //wiggle frequency
wigamt = 30; //wiggle amount
wigdetail = 3; //detail of noise
wiggle(wigfreq, wigamt, wigdetail)

to build off mathew's expression, this one will 'bump' at every comp layer marker, so you can trigger the wiggle by adding comp markers.

freq = 10;
amount = 50;
detail = 5;
decay = 10; //how fast it slows down

n = 0;
if (thisComp.marker.numKeys > 0){
n = thisComp.marker.nearestKey(time).index;
if (thisComp.marker.key(n).time > time){
n--;
}
}

if (n == 0){
value;
}else{
t = time - thisComp.marker.key(n).time;
a = amount/Math.exp(decay*t);
wiggle(freq,a,detail);
}

Have you seen VideoCopilot's plugin Twitch? Because it seems that example used just it.

thanks, indeed Twitch is about the answer I looked for, so I bought it :)


I appreciated the scripts bits tho, could use if for other purposes.
