So imagine I want to put something together for let's say a presentation with a bunch of videos in various formats, like from a phone, off the internet etc with some sounds some recorded live and perhaps some music in the background all into one 5 min long clip, how would one do such a thing?

Not too fussed on the quality and don't plan on doing it again so simple and free programs would be great!

tl;dr?

c'mon help me out.
