  • is there a paint bucket fill effect?

    I have something similar to an “audio wave effect” on the screen that animates, stretching from the left side of the screen to the right, and I’d like to color the bottom half of the screen below the wave a different color than the top half.

    I thought maybe I could put a mask around the window with the audio wave sticking out on both ends, then use the fill effect to fill in just the bottom half of the mask.

    I don’t want to rotoscope an audio wave and wondered if I can do it another way?

    Short Answer, Auto Trace to get one mask of your “audio wave effect” and the area below.

    I don’t know how you’re making your “”audio wave effect” on the screen that animates, stretching from the left side of the screen to the right,”. I used Render>AudiovSpectrum (Analog Lines) stretched from left to right. I then added an open mask, four points with the Pen Tool. The Mask is shaped like a bucket with the Audio Spectrum as a lid on that open bucket. Make sure the bucket overlaps the lid. Also make the bucket bigger than the bottom of the frame, meaning the mask points are outside the screen, so Fill will fill the whole bottom of the screen.I added stroke to the bucket mask.

    Then, Layer>Auto-Trace (Time Span=Work Area, Tolerance and Threshold at 1) to get masks of the shape of the bucket and lid.

    I got two masks on a new Auto-Trace layer, one for the inside, one for the outside. I deleted the inner mask, Mask 2, then Applied the Fill Effect (Render>Fill on AE6.5). Choose the color you want.

    !#!$!@#$ genius!

    yikesmikes you opened me up to a whole new option i was not aware of.

    I indeed am trying to make a bucket effect, but more like a glass of milk, and I got the top of the liquid to look ok by using advanced lightning, but couldn’t figure out how to color only below it.

    I just followed your notes and sure thing, it worked right away, thanks so much!
