We have now started to include some audio in to our clip, even though it is not essential we would like to include it maybe to gain a few extra marks if we are fortunate.

A sound film is a motion picture with synchronized sound, or sound technologically coupled to image, as opposed to a silent film

I belive that our group is currently considering to make our own sound track off garage band to include, although we have included a loop track for the beggining of our clip.
