I'm thinking of trying out Adobe Premiere but before I waste my time getting my hands on it, is it actually any good? Basically I'm wanting to be able to edit videos in a somewhat non-linear fashion and superimpose images (and sometimes bits of other videos) over the footage, none of which is possible in Windows Movie Maker. Some very, very basic keying (fancy term for adding transparency to a green/blue screen, but also for other colours) might be nice, but not essential.
P.S. I am of course running Windows so Final Cut is out of the question... I get to use it in college but I never have any luck importing my own stuff into it due to compression codecs it doesn't recognise or something. Plus, you know, college isn't my house. Yeah anyway, has to be a Windows program.
