Going through my short film, I have the risk of having too much or not enough filming to fit the duration of a short film. Around five minutes or a few minutes longer.
If I don't have enough:
I will be writing an extra script that'll go in-between some point of the short film to add a bit more in the story. The scenes will be different to what I already have planned out so I have opportunity to go different directions with the short film.
If I do have enough:
After putting the actual short film on a disc. I will put deleted scene on another. This will allow to demonstrate the other ideas I have stuck with and filmed. With the deleted scenes, I will also include bloopers and possibly some clips of before and after filming.
