    Looks fine, but I was rather expecting something more realistic ;)
    Although very useful info :D

    I really liked this! Really well presented Ewan! It’s hard to get the dynamics correct when working with 2D layers and expressions… but this is coming really close… AND NO KEYFRAMES! haha…

    Good job man!

      …well someone’s in a good mood, shouldn’t you be taking care of the baby?

  • Lyndon

    Dude, freakin sweet! I so wanna punch some jello now :P

  • Lyndon

    Dude I hate to sound like a tard but I totally got lost typing in that expression. You mind providing us w/ a simple copy and paste to get the jello jigglin?

    thx in advance.

      Hi, here’s the expression in full:

      warp =effect(“Warp”)(“Horizontal Distortion”);
      decay = .9;
      end= 0;
      duration = thisComp.frameDuration;
      current = Math.round(time / duration);
      amount = 0;
      for (f = 1; f <= current; f++){
      difference = warp – end;
      amount = (amount – difference) * decay;
      warp+= amount;
      }
      warp

      • Lyndon

        You’re awesome

      • Lyndon

        Phew! Finally got it, thanks man :)

        warp=effect(“Warp”)(“Horizontal Distortion”);
        decay=.7;
        end=0;
        duration=thisComp.frameDuration;
        current=Math.round(time/duration);
        amount=0;
        for(f=1;f<=current;f++){
        difference=warp-end;
        amount=(amount-difference)*decay;
        warp+=amount;
        }
        warp

        warp=effect("Warp")("Vertical Distortion");
        decay=.7;
        end=0;
        duration=thisComp.frameDuration;
        current=Math.round(time/duration);
        amount=0;
        for(f=1;f<=current;f++){
        difference=warp-end;
        amount=(amount-difference)*decay;
        warp+=amount;
        }
        warp

        That should work :D

    And here’s the French version for copy/paste:

    warp = effect(“Déformation”)(“Distorsion horizontale”);
    decay = .9;
    end= 0;
    duration = thisComp.frameDuration;
    current = Math.round(time / duration);
    amount = 0;
    for (f = 1; f <= current; f++){
    difference = warp – end;
    amount = (amount – difference) * decay;
    warp+= amount;
    }
    warp

      Super ! Merci ! :)

  • random

    thnxx dude the tutorial of yours is very good and i enjoyed learning it

    once again thnxx for the share ;)

  • Leilani

    I love the tutorial, but I can’t get my expressions to work. I’ve copied and pasted the expression code but I get an error saying:

    After Effects warning: Syntax error Expression disabled.

    Error occurred at line 1.
    Comp: ‘Animation’
    Layer: 1(‘Jello_Text’)
    Property: ‘Horizontal Distortion

    Any ideas?
    Thanks! =)

    Most of the tutorials on this site won’t play, it gives a playback error message. The commercials before the tutorials play fine…of course, but the tuts won’t play at all. I’m on Mac OSX and have tried both Safari and Firefox with the same result.

    Also, I wish there was a link to report problems like this instead of having to post in a comments thread since there’s no way to know if anyone from AEtuts will even see it. Just a suggestion.
