Hello.
I've got kind of a problem. Me and my friend are doing a school project about computers, their history etc. First, we wanted to do a presentation about this in PowerPoint, but because of compatibility issues (MSO vs. LibreOffice in school) we'd rather like to do a simple video about it, kinda replacing the standard presentation.
My first idea was to do things like this in Sony Vegas, or Camtasia - you know, just copy some text, add some images, simple effects, music, etc. But it's really not optimised for doing things like this - it's slow and even simple text formatting takes high amount of time.
My question is, is there any software that could help me in this situation? Maybe some plugins for programs like Vegas?
Thanks in advance.
