I need a step-by-step instruction on how to do this with After Effects or any Adobe software that you might recommend.

I've been browsing around the net and can't find a clear answer. The keyframes thingy are too complicated for me so I need a simple solution like the one in the video. I am using Windows 7 so I can't buy the Apple software. Can After Effects do this or should I use Premiere Pro? I'm relatively new at video and audio editing. I want the picture to bounce in sync with the drum beat or cymbals like every 4 seconds or so. Not only that, I want to control the direction to where it bounces to - upper left, upper right, center, etc.

If keyframes are too complex for you After Effects isn't your tool of choice. I've got 10 year old cub scouts that can use AE. I'd take the bull by the horns and dive into the basics by following this link. 

Once you have a little more confidence you can run through a tutorial, any tutorial, on using Audio Keyframes. The procedure is very easy. It goes something like this:

  1. Put the audio in the timeline.
  2. Use Animate>Keyframe Assistant>Convert Audio to Keyframes to create a null named Audio Amplitude and effects sliders named Left, Right and Both
  3. Put the image you want to control in the timeline and press S to reveal the scale property.
  4. Alt click or Option click on the stopwatch to begin an expression.
  5. Use the pickwhip to connect scale to the Both Channels slider.
  6. Open up the graph editor, select the Audio Amplitude Both Channels Slider property to reveal he range of the levels you want to use for your animation.
  7. Screen Shot 2011-10-06 at 6.31.17 AM.png
  8. In this case I want to use 25 to 60 so anything below 25 is 50% scale and anything above 40 is 100% scale
  9. Modify the expression created in step 5 to look like this:
  10. temp = thisComp.layer("Audio Amplitude").effect("Both Channels")("Slider");

    s = ease(temp, 25, 40, 50, 100);

    [s, s]

You're done.

Sorry about that. I'm not very familiar with the terminology and don't even know what a layer is. My video editting experience is very limited because I only used MovieMaker. Thanks for your instructive response and link to get me started. I'm sure to read the material you provided me. I really appreciate it. Cheers!

I love your posts, Rick, but this is perhaps the funniest thing you have ever said in this forum.

And I'm proud of everyone of my cubs in Pack 1849. The greatest test of my humility came when a 10 year old answered a post I placed on an xcode forum concerning an app that I'm working on for an iPhone. He suggested a video chat. I took it. In 10 minutes he solved my problem. The app is coming along nicely thanks to pubescent kids who post their IOS tutorials on YouTube.

Getting back to JChrisG's problem, If you don't know what a layer is you must learn. It's not that hard to get enough of a handle on the technology to start making animations. Start HERE.

Hi, I am trying to achieve something similar but the coding part still seems a bit alien to me. I have tried to mimic what you did and wrote the expression exactly as you did but After Effects says This project contains an expression error. I am at this point confused. Not sure what I am doing wrong. Before modifying the expression everything works but is of course behaving way too extremely for my taste.

What is the full text of the expression error message? Could you show us some screenshots of your expression and the relevant layer effects it is pointing to?
