The Product you link to uses templates; you drop in your content, rest is 'auto mode'.
If you like it quick, if you don't care, -zillions of other video look like yours - just do it.
You need a super-fast UPload internet connection.
And pricing and ToU are a bit … weird, for my taste
(the free videos are only ony THEIR YouTube site? wot??)
iMovie (pre-installed on any Mac) offers a few templates too, but is basicly a 'full flavored Non-Linear-Editing tool'
ok, maybe not sooo 'full flavored'
Watch the turtorials…
... That SnapThingie is the moving-image-variation of Instagramm:
Pick a 'look' - done.
Results in: all look same.
None look like the professional done demoes on the manufacturers website
