The music video for "Left Behind", directed by Dave Meyers, focuses on a young boy, first seen cutting up meat in a meat market. He then goes to his dirty, rundown home where bullies throw stones through his windows. The boy pours filthy water on his Froot Loops and watches an old television set which faintly bears the word "Slipknot" in static. The band is shown performing the song in a dry, dead forest which, toward the climactic end of the video, turns to night and is heavily rained on. As the lead single, "Left Behind" also marked the video debut of Slipknot's new costumes in promotion of Iowa.
There are two versions of the video, a slightly edited version (for airing on TV) and an unedited version for the DVD.
