Getting into motion design with After Effects can be quite intimidating, but there are a lot of similarities between Adobe's motion graphics, animation and video editing tool and Photoshop.
After Effects is a complex, huge application – just like Photoshop. But there are plenty of After Effects tutorials around to help get you started, so with a little time and patience, you can master the basics.
A seasoned Photoshop user should be able to get up and running with After Effects within a weekend, if not a day.
After Effects presents the features you need to create stunning moving images and motion graphics; it's up to you to provide the ideas and software solutions to make them happen. Just like in Photoshop, a little experimentation goes a long way.
