Here's the breakdown of the video tracks. View the image above to see how I stacked them!
Video 1 = Background (in this case, the "matrix-esque") design.
Video 2 = Footage of me in front of the green screen, colored keyed out.
Video 3-5 = Emoji .png still images (found via Google search)
In the .gif animation above, you can see how I animated each emoji individually: left to right, down and up, or diagonally across the screen. I clicked to select the specific emoji clip on the timeline that I wanted to animate, and then chose the tiny pencil icon that pops up when you hover over it. One of the editing options is to "start" and "end" your image at two different points on the screen. When you preview the clip, you can see the image slide across the screen!
