Seamless transition
You can put on repeat animation with a smooth transition between frames when one scene imperceptibly turns into another, can’t you?
Seamless transitions draw your attention at once and maintaining it throughout the whole motion. The frames move fluidly from one to another. Graphical elements and camera movements add some more effects acting as tools of scaling, rotation, zooming and spinning to achieve the right goal.
Here is another shot from Aver project with a catchy seamless transition that will surely gain your heart (at least we hope so :)
