I have no audio or video of any of my four grandparents. As they were all born in the first decade of the last century, this is hardly surprising; they didn’t live long enough to have smartphones pointed at them.
I suppose the only people of their generation recorded for posterity were those who worked in radio, film, television or music, or anyone who made the news. If your nan or gramps wasn’t some kind of celebrity, footage of them probably never existed, unless you had a cine-camera enthusiast in your bloodline. I don’t. No, this kind of remembrance was the preserve of a privileged few.
