Exactly, that is all science 'fiction'. Its not possible to add data that was not there before.

There have been a lot of advances in this recently - I'll have to go and find some of the submissions here on HN that suggest that it's not as far fetched as people often assume. You'd expect it to be science fiction to read sound off vibration of leaves in a room, but that's been done. You'd expect it to be science fiction to eavesdrop using a cell phone's accelerometer, but that's been done. Correlate several frames together, increase the contrast, who knows what might be possible. Or, you know, build the next "To Do" list manager or Candy Crush replacement.

I think that most of the users here (including the OP) understand the difference. But sometimes there is some information in the video. For an unrelated success case, you can read the reconstruction of the video of the first spacex "landing" http://www.nasaspaceflight.com/2014/06/recovering-falcon-9-ocean-landing-video-done/ http://www.nasaspaceflight.com/2014/06/recovering-falcon-9-o... Another case was the reconstruction of Pluto surface using images of the Hubble in 2010: http://www.nasa.gov/mission_pages/hubble/science/pluto-20100204.html http://www.nasa.gov/mission_pages/hubble/science/pluto-20100... In this video the resolution is good, the problem is that there is a big reflection over the windshield that covers completely the driver. Perhaps if you can subtract the reflections and take an average between all the frames of the video you could get something. I'm not very optimistic. I'll be happy if it's possible to count how many passengers were in the car. Tall/Short. Fat/Thin. But I guess it will not be possible to get facial details. [Somewhat unrelated: A few years ago, I analyzed videos to track particles with a resolution on 1/10th of a pixel. It was easier because the particles were round, so you only need to guess where they are. But obviously it was not possible to see if they have a smile face painted on them.]
