    This is the highest level I've seen on a tutorial... like ever.
    Perfectly planned out, explains all the details and no wasted time.
    I rarely comment on stuff, but this tutorial deserves some serious love.
    Thank you!!!

      thank you for the kind words. I'm glad it ticks all the boxes for you.

    the amount of work that was done before opening after effect to explain it is amazing i love it thanks !!

  • @AlanCrytex
    @AlanCrytex Před 6 lety +21

    I really love the effort you put on to demonstrate how it basically works in the beginning! Thank you for the tutorial.

    • @ECAbrams
      @ECAbrams  Před 6 lety +3

      You're very welcome. Glad you enjoy it. I'm going to try to stick with this kind of format for basic expression tutorials moving forward.

    Thank you for breaking this down in plain english! I am not math-minded and have hesitated to learn expressions because it's not the easiest thing for me to pick up immediately, but the clear explanations paired with accompanying visuals made this soooo much easier to understand. I also appreciate your delivery -- digestible for a beginner without skipping over the basics or sounding condescending

    • @ECAbrams
      @ECAbrams  Před 6 lety +13

      This comment has made my morning. There were definitely earlier scripts and recordings that were a bit too "math-splaining". I feel like taking the time on this was just validated :)

  • @maryamsamadi4714
    @maryamsamadi4714 Před 6 lety

    Besides subtracting in-point time from current time, you can determine the phase (in radians) of the wave according to y=a*sin(2*Pi*f*time+phase) but it gets a little sciency. Your solution is easier.

      Thank you very much. I'm trying out some new audio gear here so I'm glad my voice is comforting, rather than powerfully grating. It might be my Canadian affect. We could get into some process stuff. I do often get into that on live streams, which is also a thing that happens on this channel.

      Perhaps. I don't use that one as much in my work. I think we may get into some of the random functions like random() and noise(). But we will certainly come back to the Math family soon enough :)

  • @shawns9902
    @shawns9902 Před 6 lety +2

    Evan, is it safe to assume the intro section from 2:29 onward (the black and blue wave shapes) was created using Wave Warp or is there some way to apply Math.sin to shape paths?

  • @motionology3667
    @motionology3667 Před 6 lety +5

    Math.sin() - The entire swinging motion occurs from this expression. Math.sin() creates a sine wave, an
    occilating value positive and negative from the original starting value it is given. There are two values
    that you can give this expression to effect it’s output. The first being it’s source value,
    Math.sin(SOURCE VALUE). This is traditionally assigned to time, since time’s value increases
    exponentially with each frame of your After Effects timeline. The second value isn’t really mentioned
    anywhere, it literally is an optional modifier where we basically multiply the resulting output value of
    Math.sin() by another value. This increases it’s overall resulting value. You do this by using the “*”
    multiplication operator. So Math.sin(time)*20 will produce a value 20 times greater. In addition to
    modifying the final result, you can also modify the speed of time in the same way. So
    Math.sin(time*2)*20 will make time move 2 times as fast with the same 20 times greater value.
