I got into it because my parents produced a video about the area I grew up in, back in the late 80s, and I only have VHS copies. The master tape is probably lost but the guy who shot it said there might be a copy made about 20 years ago on DVD that the editor made for archival purposes.

Since then it's turned out that people want their old tapes copied over quite a bit. I don't do it "professionally" simply because I cannot afford to dedicate that sort of time to it, because people actually expect it to be done more quickly than "okay today I have a full day of Teams calls where I don't need to say much so I'll get on with something fun" ;-)
