I got an oldish videocamera from a friend for free today, but it only records VHS. I want to be able to put footage from it on my computer without having to use a converter box. Is there some sort of thing I can get that I can wire up inside of an empty VHS shell that will convert the signals from the videocamera real-time and write them to files on an SD card? There is RCA output, so maybe I can do something with that?
