The Hitchcock system by FX Pal is a computer tool that edits your home video for you!
First it sorts the good shots from the bad, using a wide range of image analysis techniques.
Then it computes a suitable length of all the clips, and suggest to you three versions of different length.
In the Hyper-Hitchcock version, the different versions are interlinked with hyperlinks. They call it detail-on-demand (and not stretchvideo).
Sounds pretty amazing, huh?
