actually video you got from MV Master app is RGB + ALPHA Video which is used to create MV video effects. you got both video in one video . both video has black color so by using ffmpeg we have to pass black color code to ffmpeg command. ffmpeg will use that black color as transperent area and after that we have to overlay that video to image
