As I start to dig a little further, the thing that I would really favor in creating output DVD slideshows/movies is to be able to add "chapters" so that they can be indexed and an individual can start with something right where they want. I'll be creating a slideshow for my daughter's cheer team from fall (football) through winter seasons (competitive). And even there, there are three distinct rounds during competitive season. And of course, final end of the year sports and awards banquet.
So in replacing Premiere, I want those chapters. As I start to learn each of the replace open source products, I've found that Windows Movie maker may not be able to create those chapters (I'll continue to try it out at any rate). But the bigger issue is that it does not appear to be able create a DVD in a standard dvd format that can be used on any player.
So that lead me to further searches and it looks like I've stumbled into an additional 'open' source cross platform tool.
One Warning I can offer, do not just accept 'standard' installs as they seem to include bloat/crap ware.
However the other tool I found this evening is one called "DVDStyler" :
DVDStyler - Free DVD Authoring Application Downloads actually appear to be hosted on Sourceforge.
It looks like even if I use Windows Movie maker, I'd still have to import it into DVDStyler to actually create generic DVD. According to Microsoft, the Windows Movie Maker can make DVDs, the video format is windows "wmv" format and while "most" DVD players may work, I'm fearful that some families on our team will inevitably have a player that won't work (and I'll need probably need between 30 and 40 for families/grandparents and separated/divorced parents). I don't want to take the chance that the 'movies' won't work.
The saga continues...
