I have some audio and want to add visuals to it and upload to YouTube.
Nothing fancy, just like slides,
00:00:30 and so on.
I have recent Mac and Windows machines to do this on. I'd like to do it on free or demo software if I can.
Please give a bit of a hint how to get started if you can. I took a look a iMovie, but … where to start, if you haven't actually got video?
