I found this very Interesting. I thought that the sound comes from the video recorded but it';s not, shame on me hahaha. It fools me a little bit.
We might take sound for granted when we watch movie.
Agreed or not we do. Sound is very important for every movie. Have you ever watched a movie without a sound? In my opinion, sound gives us what the movie want us to feel. Like in Horror films when it comes to the moment of intense the sound goes stronger or sometimes faster, in romantic films the sound is kind of having slow beat that would captures the audience mind to focus on what they see not what they have heard.
If we watched a movie we always remember the actor or the people who used to portrayed it and from that we tend to forget the sound which was a very important aspect.

I could say that the secret of Foley is pretty much cool. When I saw the Video from the post, Foley artist are having hard times on doing synchronized movement with the use of right materials to stamp, to hit and Etc. to attain the sound of what should it be. Foley was made a remarkable art using sound effects that is very essential on filming. Such a great contribution. :)
