Need help finding HQ game images for numerous games

Does anyone know good ways to capture high-quality images from match videos? Are there any programs that I can use to get images that will print-out perfectly on a full 8.5"x11" sheet of paper. I need to get a large number of HQ images from numerous games and I need them to print out well.

I haven’t found any images on the Internet that are close to being what I need. I figured this would be the place to come for help.

Edit: I figured that since this isn’t just finding images, but involves getting them for myself, it didn’t fit in the “find and image thread.”
