Apparently they've been erasing more arm rods again as well.
But yeah, videotape was always intended to be standard definition, so it's not like it can be remastered into HD without actually up-converting it, which is, unfortunately, going to distort it somewhat; unlike film, which actually has a natural resolution that's even higher than HD, it's just technology has only been able to catch up to it - in fact, 8K is the closest we've come so far to matching film's resolution.
