Footage not being used and Outtakes

Here is a brief sample of some of the footage not currently being used within my project in the form of a 5 minute video

I estimate that I have filmed over 4 hours of footage in total. However, I have distilled it into this video. There are some obvious reasons such as orientation that these clips have not been used . However, many of them were not used purely because there was not enough space in the video . Also included is footage that was rejected originally for it being to shaky. I attempted to stabilise it using the built in stabilisation of Imovie but even that did not work and thus the footage was redundant.
