Continunity

This is a fundermental principle of moving image production. Continunity is normally secured by producers following the conventions of the classical realist text, this allows the plot and story to unfold in a way that the audience can assume what happens inbetween each shot or sequence. For example a person travelling on a train, the audience will not think it is short and they will assume inbetween shots there is nothing of significance. But if the character moved then the continunity rule has been broken.
