Most files can easily be compressed by using compression software such as WinRAR or WinZip. Video files, however, require their own compression software as they must be compressed without interfering with how the video or audio is displayed. Video compression software is easy to find and may include basic or specific tools to compress videos and perform related tasks. To narrow the user’s search for video compression software, a number of video compression programs have been listed below.

Sorenson Squeeze 6
Sorenson Squeeze 6 is a video encoding software that is capable of compressing videos to a fraction of their size. It also modifies existing attributes of the video such as brightness, sound levels, and pixel ratio.

Sorenson Squeeze 6 includes both one and two-pass variable bit rate compression, high definition encoding options, and audio and video filters.
