animation breakdown

The video has been set to private, but based on your other responses...
Have you watched through Adobe's provided tutorials? YouTube is a sea of info, with wildly varying quality, but Adob'es stuff will get you through the basics with some clearer structure.

There's also a great series here (commissed by Adobe) to get you familiar with a lot of the basics of the UI and workflow.

That would be as trivial as cutting out the individual images in Photoshop, importing them and animating their positions, then add a few effects for drop shadows and color corrections.

If this part is animated, what are the animation techniques?

There's a million things in each of the assembled clips alone. You can only learn the individual techniques and then apply them, which includes mask/ shape layer animation, tons of cutouts, making hair wobble with distortion effects, using Wave Warp and others to create spiky/ wavy patterns and so on. Point in case: The individual techniques are basic stuff, it's merely a matter of how they are applied and strung together. You can find enough tutorials on those by searching for terms like "graphical splash animation", "splash writing" and similar.
