Twitch Expression (Part 4) – Adobe After Effects Tutorial

So you want to make things twitch around but hate having to keyframe? Enjoy saving some sweet time with this expression tutorial series.

Part 6 of 6 of the Twitch Expression in Adobe After Effects. You can use this in any version of after effects so long as you can write expressions. If you follow all the steps though I’m sure you can do it.

If you’re finding this one too hard check out part 1 and go from there.

If this is too easy for you check out part 5, it’s a heap of fun.

Youtube won’t allow the characters in the expression so… not totally sure how to get you the expression if you need it. But if you pause and look at it you should be able to get it. Any also typing is fun right?

Thanks for watching in have a nice day.

    This is pretty cool , any why to get the a to be related to the waveform amplitude? Also have that damp out?

    it was [x,y]

    probably. That means like [x,y] no [x].

    my code must be of dimension 2 not 1?

    Thank you very much! I've been experimenting with this a bit and I can do a lot more stuff now! On the Amplitude slider I've put the time expression and that time expression leads to another slider so now I can actually make some sort of earth quake effect that is sliding in and sliding out! All because of your tutorials, thanks dude!
