Movie files show in Mac OS X Finder with an example frame from the movie. Unfortunately, it's captured from fairly early in the movie, so that different episodes of a series, or perhaps different movies from the same studio, will all end up with with essentially the same frame from the titles, rather than having a distinctive icon. (Which would sure be nice for my son, who can't read the filenames but would instantly recognize many frames from the films that fill our drive on the media machine.)
Best solution would be if I could specify which frame of the movie is used for the icon. Sort of like how, in Keynote, you can scrub to pick the representative frame to show before the movie on your slide begins playing.
Perhaps 2nd place would be if I could just change how far in it samples (maybe instead of 10 seconds, or whatever, 2 minutes in would be more likely to show a distinctive capture).
Anybody know how to do this?
