Dynamic Link and After Effects; Working with After Effects … Mikey shows how to work with the random seed layer, and link multiple wiggle expressions from numerous layers together to create a wave effect. This is achieved by setting the "seed" value, which will tell. Something confusing you may run into when working with the random expression is that properties calling for two dimensions, or two values, need special attention. Hence, I can't just draw a random sound wave and use the Trim Paths effect. A common effect you see in music videos is an audio waveform, often overlaid on the video action, that pulses in sync with the music. I searched there and on several similar sites. A typical range would be 0 to 20 for both channels. With regards to your file - I downloaded it, but for some reason I cannot replace the music file with my own. Simply change the seed value if you want a different opacity value. Audio Spectrum is not going to generate waves that look like those. You can type any number you want for the minimum and maximum values, but the smaller number should always be the first number. Another option might be to create a gradient filled shape layer then control the start and end point of the gradient with the data from both channels. Here's a good description of what waves … These multi-value 'buckets' are called arrays. Tell me, please, where I was wrong. Instead of typing in a numerical value, you can have After Effects use the layers number.
