This is not just a new simple slideshow template. This is a very handy and easy Slideshow Builder Template.
The key difference is that it contains lots of premade layouts and titles not stylised to fashion, business or game, cinema type of graphics. All elements are pretty universal. So they can be used, as shown in preview, in any type of photos/video/text demonstrations.
For the best result it requieres some knowledges and skills from user to work with After Effects. The archive has three tutorials and three premade simple examples of different customization (fashion, sport, corporate)
The main feature is expression controlled animation with time offset / delay function.
Just make one animation and all slides will repeat it one after another without any hard keyframing.
