Welcome to our community, Mario
As with anything, the answer is a definite "it depends".
You are able to create it all in a single project. But I'd
only do it if I were certain that each segment would be about 10
slides each.
Personally, I'd plan on 10 different projects. Before
embarking on this adventure, you need to determine what size will
work best. My personal preference is to stick with 640 x 480. But
many also choose 800 x 600.
This way, if all 10 projects are sized identically, things
are more consistent. You may also find you need to combine two or
more. Or share assets. This will all be easier if they are all the
same size.
Cheers... Rick
