How to Get First Image of a Movie (.mov)

[R. Hillen]

Hello List,

I want to make a inventory over a lot of little movie-snippets.

 From Users Point of view
- he drags a movie-snippet onto a card,
- the card script calculates the URL of the movie and puts it into a 
field,
- a script gets the first image of the movie and puts it into an 
image-object.

Any hints, how to get this first image?

Thanx in advance.

Richard.
