Meet this artist I know.

Sarah, aka Seduff, is a 28 year old TV editor from Australia. She has a BA in Media Studies/Graphic Design. She spends her free time editing videos on youtube. She likes to take TV shows she enjoys and re-edit the scenes. One of her favorites (and mine) is a British TV show called Doctor Who.
Sarah is a true artist in the sense that she edits in such away that the clips (although pre-existing) become a story of their own. She can make the clips take on emotions that were not present in the original episodes from which they were taken.
Even if you are not familiar with the shows, you can get an understanding of them because of the way they "become" an episode in themselves.
Below is an example of her work titled The Lonely Angel. Again, these are clips which are taken from many different episodes of Doctor Who and joined to make something entirely new.
