I am looking to have a logo fade from the left, right and top until it appears as a small circle. I am very new to After Effects and wondered if someone could point me in the right direction. Thank you!
You can add a mask with a feathered edge and animate the mask.
You can create a gradient the shape you want to fade to assume and use Gradient Wipe.
You can use blurred layers as track mattes and animate their position.
But it sounds more like you want to transform the shape of the logo and deform it into a small circle that disappears. If that is the case then the options include the distortion tools in AE. Fading usually means opacity so when you say turns into a small circle I get confused.
