Well any image format is fine since it's easy to convert between formats 
without user interaction.

Yes so you either know the frame or byte position or time, and the number of
frames required. So what's difficult about building a simple script to control
this automatically given an input file, eg:

	movie_file.avi		start-pos	no_frames
	movie_file2.avi		start-pos	no_frames

etc...

There is no clicking involved in this either?? 

I doubt you're going to find a solution that does exactly what you want, but
mplayer with a shell or some other script controlling it can do what you want
automatically. I'm not pushing mplayer - if someone else knows something that
can do this easily on the command line then plz share.


OK I just tested it, it appears produces 1 png file for each frame 
(so that = LOTS of files). And of course when the video-out method is a file
no graphical windows are opened, it's all command line.
