Im guessing he changed vid settings to full blast (if they arent there yet anyway). Then turn on AntiAliasing.
Open the film in Film viewer, get to the scene youd like a screenie from, hit "pause", adjust view/angle, click on "Full Screen" button to the right. Wait till all the graphics are loaded again, then "Print Screen" on your keyboard. Open Photoshop (or any other pic editing software - even paint works). Paste the screenie in a new file.
