There is an app I like to use on my pc called "lightshot". It's for windows or mac, if you download it, you click prnt-scr on your keyboard, and it allows you to take a screenshot where you can resize the screenshot in real time. So for instance, if you had this movie up on your pc and wanted to take a body shot of Erza, you could take a screenshot and then align a few dots on screen so it's only a shot of her body instead of the full screen :) Here's a link to it: https://app.prntscr.com/en/index.html
