This document provides steps to hide a video behind an image file using command prompt. It involves selecting a video and image file, converting the video to a .rar format, opening the command prompt, and using the "copy /b" command to combine the image and video files into a new single image file. While the combined file will appear as a normal image, using WinRAR the hidden video inside can be extracted. The process embeds the video into the image file covertly.
