In this Premiumbeat exclusive tutorial we show you a technique for seamlessly transitioning from one comp to another in After Effects.
Using a vector-based ‘eyeball’ transition I’ll demonstrate a technique for transitioning from one comp to another in AE. The tutorial covers a few simple After Effects fundamentals including:
- Creating an eyeball simulation
- Shape editors
- Using exclude effects
- Working with alpha mattes
While this tutorial is rather specific the techniques involved in making an animated eye transition can be used in a wide variety of motion graphic situations.

|1||Create a new composition, new black solid, and new text titled “Start,Start,Start”.|
|2||Create a new dark magenta shape layer. Make a mask over the first “start”. Duplicate the mask twice and drag down to cover all the words.|
|3||Set a keyframe on all the mask paths. Move the playhead forward 10 frames and position the mask path off of the letters.|
|4||Move to the beginning of the composition and move the mask to begin on the far left.|
|5||Set opacity to 0 at the beginning and end of the animation then set the opacity to 100 percent.|
|6||Offset the keyframes.|
|7||Easy Ease all the keyframes. Use the graph editor to make a curved line.|
|8||Duplicate the dark magenta layer, place it above the text and give it an alpha track mask.|
|9||Create an exact duplicate of the composition and change the text to “End End End”.|
|10||Create a new composition called middle.|
|11||Make a new null object that scales down from 100 to 50 over the course of a few frames.|
|12||Parent the start composition to the null object.|
|13||Create a diamond shape over the “Start” pre-comp using the pen tool. Make sure you turn off the fill.|
|14||Use the convert vertex tool to round off the top and bottom vertices.|
|15||Set a keyframe for the shapes path.|
|16||Move forward 10 frames and close the eyeball. Move 10 frames forward and open the eye again.|
|17||Add a rectangle to the shape layer, add an exclude intersection effect.|
|18||Parent the shape layer to the null object.|
|19||Create a new black solid and add it to the back. Create a new white ellipses shape layer and make the shape equal on the x and y scaling.|
|20||Duplicate the ellipses and create an eyeball like the picture.|
|21||Parent the shape layers to the null.|
|22||Set keyframes to scale the pupil down over time.|
|23||Duplicate the eyeball and include only the inner pupil. Set the “start” layer to alpha matte so it only appears in the pupil.|
|24||You can stylize using keyframes on the pupil position, strokes, fills, among other things.|
