*Think about a play at your child's school; while your concentrating on your kid some other kid on the other end of the stage does something funny. Now you can go back "in time" and grab both shots and even a short section of video for context.* I'm not sure that is the case. The weakest link in photography and videography is the human holding the camera. No amount of technology can fix that. What does that mean? People with camcorders tend to zoom and pan like there's no tomorrow (classic case of "just because you can doesn't mean you should"). So assuming that a normal person is shooting their kid's play, they probably don't know to shoot it wide, meaning that the funny moment will be still offscreen, since the camera's zoomed in on their kid. And I haven't even mentioned any depth-of-field settings yet. Some of the ideas in the concept are neat and make sense in theory, but in practice, you're just going to end up with way more video that none of your friends and family want to watch and are too polite to tell you so.
