What is the name of this effect in After Effects? how to create an intro animation just like this: 
                
            ? What is the name of the effect (time around 00:00:02 until 00:00:05)? I am trying to search it over Youtube but doesn't find something that I want.

The main effect that I am looking for is the text forming from a bubble and the bubble bouncing over the text. Thanks.
You can search "After Effects morphing" and you will find some tutorials which you will help to recreate intro like in this video. It's not a standart (by default) effect in After Effects. It's an animation created from scratch, probably in After Effects. It's a Shape Animation, shape morphing, mask morphing, liquid animation.
