Have you ever watched a tutorial and felt a bit peed off when there was an animation that just wasn’t explained? An effect that just ‘made’ the whole thing? This happened to me when I saw the intro to a tutorial that included an uphill wobble effect that displayed some text as it moved.
I stumbled on the original You Tube just recently and worked out how it was done. It’s dead easy and I’ve put together a short tutorial for you.
It was done using an Alpha Matte. An alpha matte is placed below a layer to act as a mask (note it will use any pixel above 0% opacity). I created the shape above in Illustrator to animate the wobble-in.
And that’s all there was to it.
Hope you found it easy to follow. 🙂 (You may have to turn on HD display mode).
