Hi Milton,
That app which crops movies sounds quite desirable. I guess it`s a similar case to the app you created for making your mosaics as to general access to it? Maybe Photoshop CS3 has something along these lines...

Mark;
Each frame in the movie has a duration of 1/15th of a second (66.67 ms) and represents 2 minutes of real time (120000.00 ms). So 1 second of movie time represents 30 minutes of real time. I put the mouse cursor over the asteroid as I was recording it and you could slowly see it drift off at about 1 arc second every 2 minutes.
I have an old app I wrote 5+ years ago that also does cropping of any movie. You just give it the coordinates and it crops a chunk of the movie out and saves it to disk uncompressed.
So once I had the original movie cropped to the size I want, I used "Export to Movie.." to create an image sequence of .png files into a folder.
Then I used Astro IIDC's "Image to RGB48 movie" to convert the image sequence into a 15 fps RGB48 movie.
Then I used "Export to Movie.." with the RGB48 movie and converted it to an .mp4 file.
HTH..

That`s great Milton!
How were you doing it again?- you were saying each second of the movie is 30 minutes in time...Is it some sort of time/lapse movie or animation done with Astro IIDC? One shot every 30 minutes I guess- but how are they combined? I`m sorry I`m showing my ignorance!
