editing and narrative

In last weeks lesson, we looked at what editing is and how it changes the meaning of a piece of media.
For example, we saw how adding a narrative to a scene can completely change the meaning - to help us see this we looked at a clip that portrayed how a show like big brother might be edited.
This sounds strange, as big brother is advertised as being 'live', however, nothing we watch on the tv actually is live, as we are 15 minutes behind what is really happening - so there is time for it to be edited.
Big brother is aggressively edited to change the meaning of what is happening, this is done to make the show more entertaining to the audience, but also means it is not real life.
This is done by the editors placing different narrative over the scene. For example, if one person was telling a story and the others were listening, we could mute that, and play a narrative of somebody saying he's boring, or we could play a narrative of someone saying how interesting and entertaining he is, and these would show the scene with completely different meanings.
We can also cut scenes to show something, for example, if we wanted it to seem like two people are into each other, we could omit all the scenes were they aren't close, or aren't getting along, and only show the scenes in which they appear to be flirting.
