The term synopsis refers to a piece of work that is a summarization of a larger piece of work. A synopsis can be written in the form of tables and charts, as prose, as an abridgment or even as a consolidated re-write of the original work.
A synopsis is often written but can also take verbal or visual form. An individual can give a shortened verbal account of an event or written work and that would be a synopsis. Additionally, production of a video synopsis exists as well, in which a longer piece of work is summarized in a shorter video.
