    Ben….this is the most ridiculous tutorial I have ever seen…

    JUST KIDDING!

    Just got around to watching the first part. When i saw your preview, my first impression was “huh….so-so.” I wasn’t going to “waste” my time with watching 3 whole parts. However, after reading all the wonderful comment you got, I thought I’d give the first part a try.

    I’m very glad I did. The way you went about creating the UI was creative and useful and the addition of expressions I have never seen made it all the better! I loved the way you actually explained parts of the expression and then showed how changing parts of the expression would change what was produced.

    The creation of a UI is nothing I will probably ever do in any of my personal projects….BUT the parts of your tutorial, especially the expressions, will come in very handy!

    So….since I saw in the comments to part two that there were people just dying for my opinion….there ya go! :D

      Thanks buddy! That’s exactly the response I was looking for… The whole point of this exercise was to teach people some expressions they may have never seen before, and show them what each one does so that they can apply that knowledge somewhere else.

    I was looking forward to the third part… very exhaustive tutorial covering even small details, and this should be very useful for a beginner in the art of AE.

    Thank you Ben – I learned a lot from this tut!
    1 question if you have time – is there a way to slow down the random speed of the numbers in the expression so they don’t generate so fast?
    Thanks!

      Sorry for taking so long on the reply – been really busy lately!

      I thought I covered this in the tutorial, but I might be wrong. It was a really, REALLY long recording session. I’d watch it back, but my own voice still haunts me :P

      The following expression should make a lot of sense to you since it was done throughout the tutorial. The very first line is the one that’ll delay the counting. Experiment with changing the number in the brackets (3, in this case) and see what it does!

      posterizeTime(3);
      S=thisLayer.transform.position.speed
      S
      Math.round(S*10000)/10000

    I was the designer and lead animator on the Terminator Salvation “machine vision” sequences, and am honored that our work has inspired these tutorials!

    After Effects was our primary software, and most of our techniques were very similar to the ones you have outlined here. In some cases we animated things by hand that you have scripted, and in other cases we ended up with much more complex setups.

    The most involved use of expressions was in creating a curved altimeter style widget for the T800. It was built from the start with the ability to art direct every element using sliders and other expression controls (about 30 by the end) in the base comp. Here is and example of some variations I threw together by adjusting a couple sliders: http://www.jeremycox.com/stuff/HUD_demo-web.mov

    My one critique would be your use of typeface. This is mostly just a warning to others, but using OCR-A will always make your work look dated and there are all sorts of interesting alternatives out there.

    Good job!

    - Jeremy
