What you need to know is that the system didn't record at a real-time rate of 30 frames per second, but at something like 5 frames a second. So everything looked exagerrated and outrageously violent.
I saw a re-enactment of this specific case on a Court TV show a couple of months ago. They showed somebody in a split-screen of 5 frames per second and 30 frames per second doing simple stuff like picking up a doll and putting it in a crib, and it showed exactly how false this "evidence" was.
Yes, I say the camera/recorder manufacturer is solely responsible for her imprisonment.
Ok found a link for a basis of my earlier post:

The only new development was that an actual expert pointed out that time lapse video had been snapped- off at between four and seven images a second, compared to 60 images on a television-quality tape, creating a herky-jerky illusion.
''There was no assault,'' said Grant Fredericks, a former police officer and a noted instructor in forensic video analysis. ``It was so obvious to me and obvious to any forensic video analyst who looked at the tape.''
Indeed, an expert hired by the Broward state attorney's office came to the same conclusion.
