If you want to make videos family friendly, it's probably better to aim for removing violence than nudity, as one is clearly worse for the psych than the other. Expansion: how are nude scenes not family friendly? Not trying to start any flame wars here, just trying to understand how one or two scenes with nudity suddenly means the video is not family friendly? We all go through life seeing nudity, so should be fine.…
One film I think of in this regard is Schindler's List. I've seen both the original and the TV edit that Spielberg made to broadcast for teenagers to see. The primary edits I noticed were sex scenes and post-sex nudity. Those scenes weren't gratuitous(they showed something about the characters) or anything, but were edited(either cut or blacked out part of the frame). BUT there was still lots of nudity in the edited film. This was nudity of a different nature. People forced to strip down and paraded in the open for inspection.
Sometimes parents just want to take the easy path and consider all nudity as out of bounds for their kids. I think that's fine.
