There are a variety of free programs available that can re-encode a video to a smaller size using the x264 codec. For example, most professional encoders use MeGUI and StaxRip. These are excellent programs but they can be kind of complicated for the average computer user. You might know these releases as “300MB movies” or something like that.

Today I’m going to show you how you can re-encode a video using only one program – you don’t have to use any other external software. You don’t have to know anything about video encoding either; I’ll explain every detail as we go on.
