RE: Video from before the time of video
Now that's quite a project there but really interesting.
I remember watching some old super 8 cine films at home when I was a kid. There was no sound on those. I remember my Dad had a clockwork type camera which only ran for a limited time before having to rewind it.
A friend converted these old films and put them on DVDs. Some of them I had never seen before. It was interesting to see them as there was some footage of my grandparents. They didn't really look how I remembered them but I expect the films were taken when I was little, so they were probably only in their early 60s. There was footage of me crying all the time...I was a really miserable child apparently.
I hope you find some hidden gems in there Steve. It's a very nostalgic and lovely thing you're doing.
