Collage vs Montage???

We learn that a collage is: an art form, made from different media.  It can include newspaper, photos, colors, natural stuff like leaves, flowers, grass etc. and a montage is: the process or technique of selecting, editing, and piecing together separate sections of film to form a continuous whole. But really what is the difference well let me tell you with simple words. A collage is a set of pictures and a montage is a short of video clips. Here is an example of a collage and a montage.
