destroyed meaning

For this assignment i was trying to datamosh two movie clips. Didn't work out as planned not sure what i did wrong. I was trying to moosh a movie clip that i made from a previous  tel-com class last year that involved a dancing robot with a you tube clip that involved Charlie Chaplin. But instead i decided to take the picture clips and put them in a collage changed the file to bmp and messed around with it on word pad.
