Hi Marcel,
you can use the ImageJ built-in command File>Import>AVI.
The macro recorder (Plugins>Macros>Record) records the options, e.g.
run("AVI...", "select=["+dir+list[i]+"] first=2 last=4 use");
There, 'first' gives the slice number of the first slice to use,
'last' the last one, and 'use' stands for 'use virtual stack').
If you omit the 'first' or 'last' it takes the default, i.e., first=1
and last=the last frame of the movie.
If you have opened the movie, you can use the nSlices function to get
the number of frames in the movie.
