Editing is the post production section of the whole filming process though there are a lot of purposes of editing these are:
1. Rearrange the footage that you have captured into the order you want
2. Remove any unwanted footage
3. Add transitions
4. Add effects such as text
5. Add audio
6. To make the whole film flow and fit together so it can be used to view
Editing footage is used to help put a story together and helps develop the story telling. To create the story the footage would have to be put into sequence so that the story will then flow and the story will be able to be understood by the audience.
