I'm encoding a movie with TMPGEnc and i'm a little confused with the aspect ratio part. The mpg i made had the tall skinny look to it, which i know is a prob with the aspect ratio, but i'm not sure which option to pick to fix it. My problem is that i'm not sure which option will cram the whole picture onto the screen and produce the tall skinny effect like i have, or which keeps the image the same as the original file and letter box it for example. Basically what i'm asking is, what does each option for the aspect ratio in TMPGEnc literally do to the video? Thanks!
