One way that I get a closer look at something in a movieis as follows.
1. rent or buy dvd of movie.
2. Next I put the disk in the DVD rom I have on my computer system.
3 play the show to find out the chapter where the item of my interest is.
4.When the sequence begins you the frame to frame advance.
5.Each time there is a close up I frezze the frame and then save to a file.
Now that I have some stuff to work with, I can print the image or enhance it with one the imaging programs on my system.
Not sure if that would help but you have something to consider.
